LONDON W H ALLEN & CO LIMITED 13 WATERLdO PLACE SW '1893 WTMAK ASD SOKS, LIMITED, LOHDOH AMD BEDHIIL. PREFACE. The Author has been induced to republish this series of Essays, of which the original production dates from 1871 to 1889, by two considerations. First, that there is not in existence any single book treating, however generally, the whole field of Naval Defence, where the great principles of strategy and tactics are placed side by side with the material and personal conditions which, either govern or are governed by them. Secondly, that the range of their dates not only forms a record of the progress of Naval ideas, but shows that in a considerable number of cases, it has been possible to specify the causes which were in operation to produce results, and to forecast the results many years before they appeared. In general the essays form a series of inductive argu- ments, and will be found, it is apprehended, to show the general trustworthiness of that method when applied to the determination of practical questions of Naval policy. If the theory, now between fifteen and sixteen years old, which is given in the second chapter be studied, it will be seen that the principles then laid down, and arrived at by IV PEEFACE. inductive reasoning, either have produced or are producing the effects anticipated for them. Very notably has this been the case with the question of sail-power as applied to men-of-war. Inductive reasoning made it clear fifteen years ago at least, that sail-power, except as a mere auxiliary, must disappear from British men-of-war ; and it was only a want of reliance on the processes of argu- ment capable of being used, that continutd an ex- penditure over masts and sails which might have been saved with advantage. At the time of publication the Naval world is busi'^d in denouncing the very heavy gun, its necessarily small number in each ship, and the consequent character of ships which the very heavy gun determines. But this denuncia- tion, it is shown in Chapters II., and VII., written aa far back as 1877 and 1871, was certain to come at some time or other. The causes which would condemn the concentration of artillery power in a very small number of exception- ally powerful houches d, feu on board a warship were open to all from the first, and the inductive process of reason- ing might, had it been used, have pronounced against it more than a score of years ago. The importance of a systematic classification of our ships was hardly felt in 1877, when Chapter II. was written, though the reasons demanding it could be set out. It is, in fact, only the failure to employ, and wholly rely PREFACE. V apou, the iadacfcive method of reasoaing, which leads us from time to time, or keeps us, on paths over which our steps must be retraced. It is hoped, therefore, that tho republication of these Essays will not tend to create reactions which throw us back, but rather to encourage us in placing reliance on tentative experiments, and reasoning strictly based on their results. If we could say so many years ago that sail-power was a mistake, and that the very heavy gun was a mistake, but that classification was a vital necessity, is there any reason to show that we cannot test every step towards Naval change by the same processes before we em- bark on courses that will only carry us to the wrong goal in the end ? Chapters I. to VI., treat of the main principles of Im- perial Defence, and of the sabordinate facts on which they rest. Many of these principles are even now contested, and some of the facts behind them are denied. But to be right upon both is a fundamental necessity for our Empire, and we can only be right if we test every point by experiment or analysis, and then reason carefully from an established basis. Chapters VII. and VIII. treat entirely of tactical prob- lems, and their bearing is necessarily most important on all questions relating to the construction and armament of yi PREFACE. our ships. The science of Naval Tactics still remains in an exceedingly vague and unsatisfactory state ; but the Author is now, as ever, persuaded that there are no difficulties in patting it on an absolutely sound basis in peace time. He believes that proper experiments and proper inductions arising thereon, are entirely reliable as the foundation of the science ; and he has always viewed with some alarm the general apathy of British Admirals on the whole sub- ject. He trusts it may never be with any of them, as it was with Villeneuve on a great historical occasion. " No doubt," wrote this unfortunate Admiral in August, 1805 " it is thought that sailing hence with twenty-nine ships, I am considered able to fight with vessels of anything like the same number ; 1 am not afraid to confess to you that I should be sorry to meet with twenty. Our Naval Tactics are out of date ; we only know how to range ourselves in line, and that is precisely what the enemy wishes for. / have neither time nor means to agree upon another system with the Commanders of the vessels of the two nations."

IMPERIAL DEFENCE.^ Within the last few years tlie minds of both soldiers and sailors have been steadily at work on the study of Imperial Defence, and though it cannot be said that many canons relating to that subject have been universally accepted, it is not to be doubted that all our ideas on the matter are clearer than they were. Not only so, but month by month the points of difference have been defined, have narrowed the issues, and cleared the controversial field. I may be pardoned, perhaps, for assigning to my brother. Sir John Colomb, the leading part in laying down and continually differentiating the governing principles of Imperial Defence. He took up the study more than twenty years ago, at a time when it had not been touched ; and in his first pamphlet " The Protection of our Commerce and, Distribu- tion of our War Forces Considered," which was published in 1867, may be fairly said to have given the key-note to all subsequent discussions. He followed up this paper with a number of others, all clinging closely to the main principles first enunciated, while working out the sub- 1 Written in 1889. 2 ESSAYS ON NAVAL DEFENCE. ordinate grouping of the details which were necessary to make a complete scheme. Many military writers have contributed to the elucidation of the great subject, but it has been a misfortune that, as a rule, military men have closed their eyes to the long series of principles within which it is necessary to work, and have treated their own proper functions in plans of defence as if there were nothing outside them, nothing limiting or governing the details. With many of them this local defence of the land of each locality has been the be-all and end-all of their pur- view ; they have very generally agreed that the communi- cations between localities separated by water has been no part of their business to study or consider, and they have adopted the position that the idea of such existing commu- nications must be ignored. This erroneous method of dealing with the question — for the moment we suppose open communications we alter all the conditions of the problem — seems really to have originated in the Duke of Wellington's famous letter, improperly published in 1847, not so much in the words of the letter itself as in a curious consensus of determination to drop the limiting words used in the letter as if they had never been there. And yet the limiting words on the one side, and the very small addition to our means of military defence against invasion asked for (and long ago doubled) on the other, were of the very essence of the Duke's thought. ' This is what the Duke said to Sir John Burgoyne : " You are aware that I have for years been sensible of the alterations produced in maritime warfare and opera- tions, by the application of steam to the propelling of ships at sea. This discovery immediately exposed all parts of the coasts of these islands, which a vessel could approach IMPiiEIAL DEFENCE. 3 afc all, to be approached at all times of tide, and in all seasons, by vessels so propelled, from all quarters. We are in fact assailable, and at least liable to insult, and to have contributions levied upon us on all parts of our coast ; that is the coast of these, including the Channel, Islands, which to this time, from the period of the Norman Conquest, have never been successfully invaded I have in the above words represented our danger. We have no defence, or hope of defence, excepting in our fleet. . ... But as we stand now. and if it he true that the exertimis of the fleet alone are not sufficient to provide for our defence, we are not safe for a week after ike declara- tion of war In that space of coast" (that is, between the North Foreland and Selsey Bill) " there are not less' than seven small harbours or mouths of rivers, each without defence, of which an enemy, having landed his infantry on the coast, might take possession, and there- in land his cavalry, and artillery of all calibres, and establish himself, and his communication with France.'' I have printed what I consider to be the limiting condi- tions of the Duke of Wellington's alarmed views, in italics ; from which it appears that, could he have bsen assured by the naval officers of that day either that the fleet was sufficient to provide for our defence, or that it could pre- vent a French force landed on our coast from maintaining its communications with France, his alarm would have subsided. Bat even when he was far from being assured on these points, he professed that he would be amply satisfied with additions to our military forces which have long been exceeded. Taken apart not only from the limiting expressions, but from the immense changes in all the conditions which have come about since the Duke wrote, we may freely admit that this celebrated document B 2 4 ESSAYS ON NAVAL DEMNCE. formed a sort of military charter for the localisation of the defences of the Empire. For if the British Islands were to be properly and efficiently defended by local works and local military forces, so could every separate part of the Empire be defended by like local means. So also could each town, port, estuary, or coast entrep6t be kept scathless from the enemy's touch by military and local means. And the converse of the proposition might, on the same grounds, be defended. If the security of our own communi- cations across the water could not be maintained, if those of the enemy could not be destroyed, the whole value of communications by sea was lowered. It followed that more stress must be laid upon the local powers of resistance of each item of territory composing the British Empire, and less attention should be paid to the defence of the communi- cations between these items. Communications were not of the essence of Imperial Defence ; it was lucky for the Empire that they were not, for they could not be preserved in war.l ^ As an instaoce I quote from a paper by Captain Stone, read at the United Service Institation, with Lord Wolseley in the chair, on January 18tb, (1889). " My premiss is that the possession of nasrul arsenals, dockyards, and coaling stations must practically decid'i the question of naval supremacy ; that such supremacy is abso- lutely essential to our existence as a nation, and that the way to secure it is to fortify and arm our own arsenals, dockyards, and coaling stations in such a fashion as to enable them to resist an enemy's attacks, and at the same time to give a free hand to the Navy to attack those of the enemy with such force as may be available, after providing for the patrolling of our principal trade routes." And then the line, or atmosphere, of thought generated by this enunciation oE principles culminates in such an idea aa the following: "The case of Sevastopol is even more instructive, affording as it does an actual parallel to cases with which we may ourselves have to deal in the event of an invasion of our territory." That is to say, that the complete loss of command of the sea and the placing of it absolutely in the hands oE our enemies, is not recognised as a death-blow to the Empire, so long as spots of terri- tory can be kept intact. IMPERIAL DEFENCE. 5 This appears to me to be the kernel of the military thought for many years past. " The absence of the fleet " was the major premiss, not only in military writings on Imperial Defence, from that wonderful and stirring romance — " The Battle of Dorking " — through all its imitations, but through all the serious papers which military men have put forth. Not only so, but it was the same when views passed into acts of expenditure on defensive arrangements. The Navy was at first quite neutral on the subject ; a great portion of the Navy is neutral still. It generally held that it was in no way concerned with military expenditure. It laughed a little at the easy disappearance of the naval forces, either to the bottom by means which were miracu- lous in their efEecta — if that which is contrary to all experience is miraculous — or by decoy and delusion which rested on the slender basis of an argument historically sound so far as it regarded sailing ships only. But when the Navy laughed, it did so in its sleeve, and the military mind was allowed to pursue the train of thought it had fallen into, with very little check indeed from the Naval mind, which ought to have been busy with friendly and useful criticism. The Navy went farther sometimes, and directly countenanced the military theory that it could neglect communications with the vital points of territory if only each point were rendered individually secure. It to a great extent took up the simple idea which has every- thing on the surface to recommend it, and can hardly be shaken by anything but exceedingly close reasoning, that the local security of a mercantile port would always free the ships which would otherwise be necessary for its pro- tection. The idea may have been the outcome of estab- lishing as a fundamental principle the minor value of communications by sea. The Navy itself was becoming 6 ESSAYS ON NAVAL DEFENCE. permeated by the idea that in the next Naval war it would have something to do which was not concerned in main- taining commiiiiioations. What the something else was, has, I believe, to this day been left undefined. The full idea was promulgated by the Royal Commission of 1859-60, where the enormous sums to be spent on the local defences of Portsmouth, Plymouth, the Thames, and tho Medway were recommended and justified on the plea that the country would never stand the expense of maintaining a Channel Fleet sufficiently powerful to cover these ports, and therefore to preserve their water communications. 1 Yet, had we not allowed ourselves to fall into the strategical errors which we in our mistaken unconcern had permitted to the military mind, we could never hare stopped at that point. It the country would not provide a Channel Fleet, sufficient to cover these parts, what followed ? What was meant by not providing a Channel Fleet suffi- ciently powerful for the purpose? Was it meant that with all our forces assembled in the Channel we should be still too weak, or was it supposed that the something else which was not named would prevent such concentra- tion ? It is, perhaps, indisputable that it was the latter condition which was implied. But if so, then it was assumed that the commnnications over water of Plymouth, Portsmouth, and the Thames were to disappear, and might disappear without great harm, provided these three points were themselves made secure from capture and occupation. Sir John Colomb, for the first time, and, I believe alone, ran a tilt against all these ideas in his pamphlet of 1867, and especially in the following passages : — " The distribution of the forces for the protection of our 1 It is now scarcely conceivable that such an argument cpuld ever have been put forward except Id joke, IMPERIAL DEFENCE. 7 oommerce is a most imporfcant and, at the same time, & most difficult problem to solve. The magnitude of this national requirement is only equalled by the difficulty of meeting it with the means at our disposal. Like every- thing else upon a gigantic scale, it can only be accom- plished by the proper application of general principles. Now, in all naval and military operations, whether offen- sive or defensive, there is a golden rule, to neglect which is certain ruin ; it is the fundamental law which applies to all warfare, and is simply this — that the success of all operations depends upon the disposition of the forces in such a manner as will best secure the base of operations and ensure safety and freedom of communication. Know- ing this to be true, it remains with us to show how far it can be acted upon and applied to the object in view. "To determine the base of operations we look at a commercial chart, which is nothing more or less than a map of the world, showing the tracks of thousands of ships passing and repassing from one part of the globe to another. We know that on the proper distribution of our forces depends the safety of these innumerable vessels, and that this involves the prosperity, nay, the very existence of the British Empire in time of war. It is in reality the income of the nation which is thus scattered broadcast over the ocean. On examining this chart, it appears that all the tracks radiate from one point — the Channel — and that there by far the greatest number of laden ships are collected. One half of all the ships we are to protect are at and round this point. The Channel is the key of the position, the vital spot to secure against surprise, and it must ever be the base of our naval operations throughout the world. " JTow, the same law to which we have referred existg 8 ESSAYS ON NAVAL DEFENCE. witli equal force in all commercial enterprises. The base of all mercantile operations is money ; investments may be regarded as the advanced posts of monetary warfare. Upon the freedom of communication depends the safety of the enterprise. "Take, for instance, one of the great banks which lately failed. We are told the cause of the disaster was that the capital — i.e.. the money — was locked up ; the power to call in the advanced posts to the relief of the base, or capital, was wanting ; the lines of communication were cut oS by pressure from without, and the whole monetary edifice fell to the ground. " We may look upon the Empire as an immense com- mercial speculation. The base of operations is English money, which is laid out in investments in all parts of the, world. Upon the freedom of communication the com- mercial existence of the Empire depends. From this point of view, the greatest calamity which can befall this gigantic enterprise is that pressure from without which would threaten to cut oS the greatest number of its communications. That danger may, any day, assume a very visible form in the shape of a powerful foreign fleet in the Channel. The capital of the greatest commercial enterprise in the world could not be more effectually locked up than by the siispension of ' imports ' and ' ex- ports,' which would, as a consequence, follow such a contingency. "For the reasons we have briefly given, it is evident that the safety of the Channel must be maintained ; and that it is worse than useless to distribute the forces for the protection of our commerce over various parts of the world, while the base of our naval operations, the most vital spot in our commercial system, remains insecure. IMPERIAL DEFENCE. 9 As this involves the employment of a large sea-going fleet for Channel service only, it is advisable to ask the question, "Will not a fleet sufficient for this purpose be equal to the task of protecting England from invasion ? " The argument in these passages is very clear, and if it is true and complete, it must govern the whole strategy and art of defence of a maritime Empire. In such defence there must always be the two opposing ideas — that of the defence of each spot of territory apart from all the rest ; and that of the defence of the water connecting the spots of territory, considered with the spots of territory as a whole. It may easily be held, indeed often is held, that the two ideas are not antagonistic, but can be embodied and acted on side by side. I believe such an argument cannot be sustained. As a fact we know the thing is not so. No agreement has ever been come to in this Empire of ours as to how far the defence of spots of territory shall be carried, or how far their safety shall be left to be determined by the security of their communica- tions. All we recognise in practice is that there is not anywhere in the Empire a spot which has sufficient local defence, and this is equally the case with such great strategic centres as Portsmouth, Plymouth, Gibraltar, and Malta, as with such lesser centres as Albany and Thursday Island. No doubt opinion is not unanimous. There are high authorities who consider Portsmouth and Plymouth over- done with works ; and the great expenditure on Ber- muda and Dover has been condemned. But still, in the result, it is found that the argument of local defence- lessness always prevails, and expenditure everywhere goes on in recognition of it. But never, I believe, is expenditure undertaken except on the basis of the failure of com- paunioationg, That is to say, nev?r are the land defences, 10 ESSAYS ON NAVAL DEFENCE. or even perhaps the strictly local naval defences, intended to combine in any way with the general naval defence. This is invariably supposed to be absent ; that is to say, the communications are, at any rate for the time, supposed to be out. The question appears to be whether there is any other way of considering it ? The Royal Commissioners of 1859-60 were unable to combine the two ideas of defence, and their justification of the very heavy expenditure on the fortifications of Portsmouth and Plymouth rested on the sole ground that the defence of their sea communica- tions "would involve the necessity of retaining in the Channel, for purely defensive purposes, a fleet equal to any which could be brought against it, not only by one European State, but by any probable combination of mari- time powers, etc." It was not as the complement — as it has been put by distinguished officers — of the defence of the communications that the great defensive works were to be taken in hand, but on the clear understanding that this would be abandoned altogether. The local defence of the spots of territory was the alternative and opposing system of defence, and not the completion or adjunct of the other— the defence of the communications. Sevastopol may possibly afford us an illustration in point. When the British prepared to undertake its capture or destruction, there was attached to the port a very considerable fleet. The port itself was also strongly fortified and heavily garrisoned. The naval defence would have been complete if it had been able to prevent the landing at a distance from the port ; failing to do or attempt this, it collapsed, and the ships became useful for nothing but to be sunk so as to bar the entrance to the harbour. The port finally fell to the possessor of free water communications. But it IMPERIAL DEFENCE. 11 would not have fallen, for the invading expedition could not have started, had the Russian water communications been complete, and had those of the British been inter- rupted. After the siege was established, there was a certain threatening by the Russian steamships, which remained protected by the fortifications within the harbour, to interfere with the naval operations of the British. But evidently such attempts have either nothing to do with the present argument, or tend to confirm the view that the local defence of the spot of territory, and its defence by the preservation of its communications, are not concomitant. The threats of the Vladimir, such as they were, corre- sponded only to proposed sorties of the garrison, and so far formed a part of, and were subordinate to, the land defences only. Sevastopol forms the converse of the lines of Torres Vedras. Sevastopol fell when attacked by sea, and by forces resting on the sea ; Torres Vedras successfully resisted when invested by land, but with its communica- tions by sea intact. In both cases it was the holder of the sea communications who succeeded. But it was the sea communications which formed the complement of the Duke of Wellington's works ; while in the case of Sevas- topol the works stood alone. The case of Gibraltar is again analogous to that of Torres Vedras, and the converse of Sevastopol, and of all success- ful attacks from the sea, while it has differentiating features from the defence of the Lisbon territory. In 1780 this fortress was nearly starved out, because the British had allowed its communications by sea to be cut. It must have fallen, had not Rodney, in January, 1780, restored those communications and revictualled the place. But next year it was the same thing again. Gibraltar was on 12 ESSAYS ON NAVAL DEFENCE. the point of being starved out, when Admiral Darby relieved it with a convoy of 100 store ships in 1781. But both these attempts were desultory, and neither resulted, nor were intended to result, in permanently restored com- munications. And this probably for the reason that, except for the protection of Gibraltar, there was no object in keeping command of the adjacent waters. Our commerce thitherwards was insignificant, and so far from Gibraltar forming a base on which the Navy could rest, it was a great tax on the Navy of that day to preserve it. In February, 1782, Minorca, fortified and garrisoned, but with its sea communications cut, succumbed to the enemy whose com- munications were open. Gibraltar, however, withstood the tremendous attack by bombardment, chiefly from the sea, of September in that year, but would subsequently have succumbed to starvation had it not been relieved by Lord Howe, with the great force of twenty-six sail of the line. The conditions of Torres Vedras and Gibraltar were there- fore alike in so far as they depended upon the sea for supplies ; they were not alike in so far as the sea communica- tions were permanently open in the one case, and intermit- tently open in the other. Minorca, unrelieved from the sea, fell; Gibraltar, relieved from the sea, maintained its defence. But none of these cases could represent Portsmouth and Plymouth, as their supplies would come by land, and they could not be invested from the sea only. Again, neither Lisbon nor Gibraltar were, at the times mentioned, naval strategical points. At the moment it was of no conse- quence to naval operations whether they fell or stood. They were defended not as present bases, but as future possible naval bases, or perhaps, in the case of Gibraltar, only as a portion of territory which honour, and not Imperial defence. 13 utility, forbade the British to part with. What appears to be certain is, that had it been necessary to maintain the sea communications ■with Gibraltar for purposes other than the defence of the garrison, not only would the com- mand of the sea round Gibraltar have been preserved, but such preservation would have prevented all attempts to reduce the place either by bombardment or investment. As it was, the British naval force at the bombardment of Gibraltar was so small that it could only co-operate by landing the crews to man the shore batteries. So far, we do not appear to get a connection between the local defence of the spot of territory and the defence of its communica- tions by water. It seems quite impossible to say in what way the local defence by works and garrisons can assist the defence of its communications, though it is clear enough why maritime nations, which have little hope of maintaining sea communications, should fall back on the local defence of the spots of territory. The maintenance of sea communications involves the safety of the place communicated with. But we seem from this cursory examination to observe that what local and fixed defence is good for is only as a substitute for naval defence when the sea communications, eicher by accident or design, may be abandoned. There is little sign that the position of a fleet can be strengthened by works for defensive purposes as the position of an army can be. Nor do we easily get, in any form, a defence which combines both descriptions of passive force. The questions that occur, and require answering when- ever the amount of local defence to be given to a spot of territory is in debate, appear to be whether, apart from the defence of the place, it is necessary to maintain its sea communications, or whether these may be abandoned 14 ESSAYS Orf NAVAL DEP'ENCJi;. without material loss to tlie Empire, provided that the spot of territory can maintain itself apart from them ? If the place to be defended is a mercantile port, a port of call, or in the track of a great stream of commerce, but is not otherwise of importance, the communications of the place by sea are of more importance than the place itself, and it would be almost strangely uneconomical to expend upon the place itself, until every possible effort had been made to ensure the maintenance of the communications with it ; for the place cannot be touched as long as the communica- tions are intact ; and as the place without its communications is of minor value, we should have been sparing where we should have spent, and spending where we should have spared. It may be proper to take the opposite view in the case of spots of territory where communications may be inter- mitted without loss at any rate for a time, but which m.ust be preserved for special reasons. Here the non- maintenance of communications invites and allows attack, and it may be more economical to prepare the place itself to sustain it. In the days of sailing ships all communications by sea were more uncertain than they are now, and every day the means of maintaining them improve. On the other hand, tliere is little reason to suppose that the time necessary for the reduction of a place, or the cost of the reduction, have materially diminished, if it can be said that they have not increased. 1 So far the power of local defence is increased ; or to put ' The judgment of the American officers who witnessed the bombardment of the forts at Alexandria was, " that vessels are not yet, and never will be, able to fight on even terms with forts " Eeport on the Operations in Egypt : " Information from Abroad," War Series, No. III., p. 74. IMPEEIAL DEFENCE!. 15 it the other way, the necessity for heavy expenditure on the local defence which assumes temporary loss of com- munications is lessened by the advent of steam propulsion. Against a given force of attack with a given strength of defence there must be a given time for the place to hold out. If we assume a place prepared to hold out for a month, when both the news of its investment and the force to relieve it are carried by the wayward, uncertain, and moderate power of the wind, it becomes evident that the same place need not be made capable of sustaining a month's siege if the news of the investment can be carried by telegraph, and the succour can be sent by steam. Assume Gibraltar to be now as it was in 1780, a place with which communications could be intermitted without loss to the Empire, a place therefore which it is intended in the general scheme of defence should be left open to attack by sea. Then, supposing no telegraph and no steam, we must assume the investment by the enemy to have been established ten days before the Home Government could get news of it ; and suppose that when the news arrived the relieving fleet was ready to sail, we must allow a month to elapse before it could make its appearance at Gibraltar.l If then the communications of Gibraltar were not to be kept up, it was strategically necessary that it should be capable of sustaining siege and investment for at least forty days. If we bring in steam and telegraph into operation, we have the news of the investment conveyed in a few ' llodney's relieving fleet left Portsmouth on December 26, 1779, and arrived at Gibraltar on January 27, 1780. Darby's fleet sailed on March 13, 1781, and arrived April 12. Howe's fleet left on September 11, 1783, and arrived October 11. 16 ESSAYS ON NAVAL DEFENCE. minutes, and the relieving fleet arriving in fonr days. If we omit the telegraph on the assumption that the cables are destroyed, we have eight days between the beginning of the investment and the arrival of relief. From this point of view we can say that if it were necessary for the retention of Gibraltar that it should have been prepared to stand a siege of forty days in the time of sailing fleets, it need only be prepared to hold out for eight days, or one- fifth of the time, now that we are in face of steam pro- pulsion. But when it was necessary to prepare Gibraltar to stand for a certain time alone, and with its communications destroyed, imperial necessities did not demand that they should be kept up. The expenditure of money on Gib- raltar as a fortress now depends on whether the old policy can be renewed. In 1779, when we were at war with France and Spain, the whole naval force that we considered necessary to maintain in the Mediterranean amounted to no more than one 60- and one 50-gnn ship, four frigates, and a brig. There was then no great stream of commerce through the Straits of Gibraltar, as to which we had to choose whether to guard it or abandon it. It is probable that no strategist or statesman seriously contemplates now a days a scheme of imperial defence which assumes the destruction or diversion of the flow of British trade between the Pillars of Hercules. It is no doubt the fact that from time to time there springs up a certain advocacy of alternative routes to the East. Such advocacy is rea- sonable if viewed purely as suggesting an outlet in case of failure to preserve the Mediterranean route to the East. But I am not sure that I have met with any proposal to abandon the Mediterranean as a preliminary measure in thp defence of the Empire. If there are such proposals, I IMPEKIAL DEFENCE. 17 have not been informed as to how it is intended that Gibraltar and Malta are to be dealt with. In the event of onr failing to maintain our communications with the East via the Mediterranean and the Canal, we ought .to under- stand that we are either to abandon Malta and Gibraltar as we abandoned Minorca in 1782, or we must be prepared with very great naval forces for the purpose of relieving these fortresses from time to time, as we relieved Gibraltar in 1780, 1781, and 1782. We are either to give these strong places up, or we are ultimately to defend thera by the only means possible — that is, by naval means. With- out any question the maintenance of our hold on Gibraltar was, in the years mentioned, a hampering of, and not an assistance to, our Navy ; while the withdrawal of great fleets from the Channel might have left us peculiarly open to attack at home. It has been noticed by a very com- petent and observant oflScer that a connection between the maintenance of Gibraltar and the loss of our American Colonies might be established. Certainly if Howe, in the autumn of 1782, was able to quit the Channel for two months with 34 sail of the line, it would seem to show that but for Gibraltar such a force was available in North America, but it would take me too far from my subject to follow the thought out.l What we have to deal with is the illustration given by the case of Gibraltar : that while it would undoubtedly have fallen with less local defensive power than it had, it would equally have fallen had not the whole available Navy been summoned to its support. In considering the question, we ought not, I think, to suffer our minds to be involved in estimating the value of ^ Howe, leaving Portsmouth on September 11, did not return till November 14. Eight of his ships were detached. 18 ESSAYS ON NAVAL DEFENCE. Gibraltar itself. The whole relations between the systems of defence by local strength, available for a time, but after a time certain to fail, and the system of defence by the maintenance of communications, which is not limited in efEeotiveness by the element of time, are only equalled in importance by their complication. The practice we have grown into of assuming two funds, one of which is appli- cable to maintaining communications, and the other appli- cable to separate local defence, founded, as it must be, on the assumption of a failure or interruption of communica- tions, might quite conceivably be pushed to an extent which would weaken the whole Empire. For the fund is originally one found in the hands of the Chancellor of the Exchequer, and he does not go into the relative values of different sorts of defence unless called on to do so in Cabinet Council or Committee of Cabinet. So that, con- ceivably, if there should be no Committee of Cabinet on the subject, the reduction of estimate called for by the Chancellor might fall wholly on the defence of communi- cations, and not at all on the local defences of territories, which by themselves are nothing, but, considered as parts of communications, everything. And, indeed, according to Lord Eandolph Churchill's account, something very like this actually happened just before he quitted office. 1 Bringing equal pressure to bear on the War Department and on the Admiralty, he got the latter to yield up £700,000, which certainly came out of the defence of the communications, while the former only yielded up £150,000, of which possibly none came ofi the local defences. At the bottom' of the whole difficult problem — which is chiefly difficult, be it observed, from the fact that the 1 In December 1886. IMPERIAL DEF'ENgE. Id administration of the local defences is independent of the administration of the defence of communications — lies the difference of view which may be held regarding the com- mand of the sea. To those who think, as I myself do, that such a command of the sea as in all our wars with France and Spain we have held in the English Channel, is not very difficult for us to hold now all over the world, local defences will assume one aspect. To those who think that not only in distant parts of the world, but in the seas surrounding these islands themselves, we must look in future wars for conditions such as we dealt with when Rodney and De Grasse faced one itnother in the West Indies, or Hughes and Sufeen contended on pretty equal terms in the East Indies, the aspect of local defences must be entirely different. And I think it must be admitted that the latter view prevails, npt only amongst military, but amongst naval men. I am conscious myself that in my general thoughts regarding the relative values of the local defences of spots of territory, and the defences of their communications, I rate the latter higher, and the former lower, than most of my contemporaries. I always feel that in this I may be wrong, and yet every re-examination I make, every fresh illustration that I bring before my mind, with the view of balancing it, tends more and more to raise the value of all that keeps up communication by sea, and to lower the value of all absolutely fixed local defences. That is to say, I get further and further from the contemplation of a disputed command of the sea, believing that, should we negligently suffer it, we shall be taking, not the first retrograde step, but the final step which will complete our ruin as an Empire, and reduce us to a low place in the scale of nations. The difference between command of the sea and dis- 2 20 ESSAYS ON NAVAL DEFENCfi. puted command of the sea is illustrated commonly to my mind by considering France as maintaining her frontiers intact against the German armies, and thereby keeping her territory free and under her control; and France as invaded by German armies, which she sometimes defeats and sometimes fails to defeat, within her own territory. Supposing in this latter case ttat her towns were so well locally defended that the invaders could only invest them, as Metz and Paris actually were invested, and yet that the French armies should fail, as they did fail, to drive the invaders over the frontier into their own country, reason teaches us, and experience confirms it, that unless the local defences of the towns should either enable the numbers of the defending armies to be increased, or should increase the fighting power of the number other- wise existing, there would be no real strength for France in the locally defended towns. This conception follows close on the other conception — universally, I believe, accepted by the Navy from the moment I put it forward — namely, that the frontier of our Empire is the enemy's coast line. It is a very old con- ception, and must have been at the bottom of our ancient claim to the sovereignty of the four seas, or of the British seas, as they were indifferently called. But in the absence of Colonial territory, in the absence, in fact, of an Empire, and the existence only of a kingdom, it did not give the idea of that military force which it now possesses. If we are right in considering that to preserve the Empire we must preserve the control of the roads within the Empire, we cannot be right in considering our seaports as frontier towns, and our shores as defensible lines of demarcation between us and foreign forces. The two con- ceptions lie opposed to one another, and their divergence is IMPERIAL DEFENCE. 21 certainly as old as the days of Pitt, when he turned upon the Addington Ministry and selected the Admiralty, with St. Vincent at its head, as the best point of attack. St. Vincent's attitude then was no new one, and it is the general naval attitude now. It is perfectly true that every now and then we hear in naval companies of ex- pressions and concurrences which admit of a less full and hearty acceptation of the policy laid down by St. Vincent in Council, and by Nelson in action, than we sometimes expect. But this proceeds in part from feelings of tolerance and good nature towards the sister Service, which, truth to tell, were but weak forces in the minds of the two great seamen I have spoken of, and in part from the dormant condition of the critical faculty. Naval officers have ac- cepted pretty generally the term, " First line of defence,'' as applied to the Navy — a term which they never could have invented themselves — because they found it growing into general use, especially amongst military men, and because it seemed to give to the Navy something of the pre-eminently defensive character which they had in- stinctively felt to possess ever since they were children. But their critical faculty not being aroused, they did not perceive all the fallacies and incorrect conceptions which lay under the words. Yet I think the words never were good ones, and never could express a true conception. I recollect the late Admiral Sir William King Hall endeavouring to correct it in a speech at a City dinner by declaring that " the Navy was the first line of defence, the. second line of defence^ and the third line of defence." But though these words might well tpnd to modify a conception originally erroneous, they were not calculated to remove it. It is impossible to use the expression "a line of defence" without conceiving a defensive chain, liable to 22 ESSAYS ON NAVAL DEFENCE. be broken through, and with either something defensive or nothing defensive behind it; but such a conception is quite out of place in considering the functions of the British Navy. It is true that in contemplating Lord St. Vincent's naval preparations /or the defence of the British Islands separately from the rest of the Empire, Sir Edward Pellew spoke of them as a " triple bulwark " ; but then be spoke of a naval force really disposed in three lines : a main outer line of the heaviest character watching the enemy, an inner belt of cruisers, and a third body con- sisting of a concentrated reserve fleet, in case of any partial failure of the first line. But it would hardly have occurred to Sir Edward to include in his lines of defence the squadrons guarding our commerce and possessions in the East and West Indies, or the various ships acting as convoys to our trade in every part of the world. And it is apparent that we can — if the enemy's coast is our frontier — no more speak of the Navy as a " Jine of defence " than the French nation can speak of their army as a " line of defence " against the Germans ; or than the Germans can speak of their army as a " line of defence " against possible enemies, north or south. The British Navy, like the French or German armies on the defensive, must in the first instance guard the frontier and keep their territory — in this case water, and not land — free to lawful passage, and barred to the march of enemies. Should they fail to keep the frontier, they must fall back within the water territory, and endeavour to beat the enemies which have invaded it over the frontier again. Should they fail in this— as Francefailed in the German war the Empire is conquered, even as the French Empire was, notwithstanding that a sea-girt Metz, or a water-surrounded Paris of the British Empire should prove so strono- in IMPERIAL DEFENCE. 23 lucal defence that investment, aoad not assault, must be the tactic employed to reduce them. And the state of a conquered French Empire, through- oat which the communications are by laud, appears to me strictly analogous to the state of a conquered British Empire, throughout which the communications are by sea. I am unable to see any difference in principle, though there may be difference in the degree of its ap- plicability. The enemy gives the law to the territory in both cases. Fortified towns may hold out all over the land Empire, yet if the armies of the enemy hold the roads between the towns, the towns are bound to fall in due course, and perhaps without attack of any kind. Broadly it may be said that in all our naval wars this has been the case. Wherever and whenever we have been able to get the highways into our hands, the territories which they connect — omitting self-supporting continents, of course — have fallen to us. Wherever we have failed to con- trol the sea roads, we have not only made no conquest of territory, but have lost those territories which we possessed. Generalising for purposes of illustration, we must say that, without exception, we have controlled the English Channel, considered as a road to the heart of the Empire,- ever since the days of De Ruyter, in 1667. In that year the Dutch had a full command of the Channel, for Charles, listening to the economists, who had behind them the telling claim that his father had lost his head for refusing to be guided by them, had destroyed his naval force. It is illustrative of what has already been advanced as the principle of defence by fixed works, that Portsmouth was on this occasion considered too w^U locally defended to be attacked ; and it would be easy to quote the case to justify a heavy expenditure and a great reliance on such 24 ESSAYS ON NAVAL DEFENCK. ■works. But he would be a strange advocate who could soberly recommend expenditure which would encourage a return to Charles' disastrous policy. The works of Portsmouth could only have been brought into play when the game was so far given up that the Dutch were free to hold the mouth of the Thames,and therefore to invade at their leisure. But since that day we have never lost the control of the Channel, though we once had to fight for it on the spot ; and once we mistakenly fought for it when fighting was imprudent, and a beating might have lost it to us. It is not that hostile fleets have not appeared in the Channel, but it is that, with the exceptions named, such hostile fleets as appeared never felt themselves strong enough to fight for the command of the water, and as a consequence, were never able to attempt territorial attacks. In 1690 the French fleet appeared in the easternmost part of the Channel, in such strength that Lord Torrington would never of his own motion have attacked them, and yet was in his own mind quite easy as to the situation. " We were forced to fight,'' he said, " contrary to the opinion of the whole Council of War." Thus wrote the Admiral to Lord Nottingham, when off the Isle of Wight, on the 26th June : " We have now a pretty good view of their " (the French) " fleet, which consists of near, if not quite, eighty men-of-war, fit to lie in a line, and thirty fire ships ; a strength that puts me beside the hopes of success, if we should fight, and really may not only endanger the losing of the fleet, but at least the quiet of our own country too ; for if we are beaten, they, beimj absolutely masters of the sea, will be at great liberty of doing many things tliey dare not attempt while we obsfrve them, and are in a. possibility of find- ing Vice-Admiral Killigrew and our ships to the westward." 1 ■" Entinck's "Naval History," p. 584. IMPERIAL DEFENCE. 25 Queen Mary's Council, overriding the judgment of the naval men, ordered Torrington to fight ; and then ensued the partial engagement off Beachy Head, made partial, and kept partial specially by the Admiral, in order to avoid the complete defeat which the superiority of the enemy rendered certain ; and to prevent him getting that undiis- puted command of the Channel which might have been fatal to William III. The naval history of the next year is a perfect example of the whole policy of naval defence. The French were ready to invade us, as soon as they liad the necessary command of the Channel. England was aware that if the command of the Channel was wrested from her, invasion would follow. Tourville, at the head of an immense naval force, sailed up the Channel to cover the crossing cf a French army, which had orders to embark as soon as he appeared. Kussell was, however, strong enough to offer battle to this covering fleet, and the great fight of LaHogue gave to the English again their undisputed command of the Channel, and stopped all idea of invasion from that moment. The only other serious appearance of the enemy in the Channel was in 1779, when an enormous Franco- Spanish fleet appeared off Plymouth, and yet was entirely held in check by the neighbourhood of a much inferior fleet under Sir Charles Hardy. I can hardly look on the proposed invasion of 1744 from Dunkirk, and the arrival of De Roquefeuille's covering fleet at Dungeness as a really serious attempt, for his French fleet was not originally strong enough to fight for the command of the Channel, and precipitately fled on first sight of the English fleet under Sir John Norris. The projected invasion of 1759 was not at all unlike that of 1805, and in both cases the intended covering fleets 26 ESSAYS ON NAVAL DEFENCE. were beaten to pieces — in the first case by Hawke and Bos- oawen, before they could even think of the Channel ; suffer- ing in fact the fate of Villenouve at the hands of Oalder. This command of the Channel by our fleet is, then, a supreme element in the defence of the Empire, as Sir John Colomb has placed it. It cannot be omitted, argued away, or spoken of as doubtful in any possible scheme which is founded on reason. " No bulwark, no towers along the steep," can be substituted for it. They do not touch the fringe of the position. If it be argued that while the fleets of Torrington, Russell, Norris, Hawke, Boscawen, Calder, Nelson, and Oornwallis, were always able to prevent every territorial attack of consequence, so were the de- fences of Portsmouth able to prevent De Ruyter from attacking when he had command of the Channel, the answer seems to bo that these latter would neither have prevented invasion nor even attack on themselves had the Dutch been prepared for serious business. Not being so prepared, few games they could play were worth the candle, and the slightest of local defences were suflBcient to prevent an attack which could not be serious, and was in the nature of a raid only. But if the con.mand of the Channel was the only reliable defence of the kingdom when it was self-supporting and there was no Empire, how much more absolute is the necessity when there is no self- support, and there is an Empire with water roads ? If we contemplate the loss of the Channel now, we contemplate imperial ruin as a certain thing, and the conquest of these islands by investment as but a part of the ruin. And then every spot of territory we possess, which is not self-supporting, is only a smaller edition of the defen- sible status of the British Islands. If we contemplate our communications by sea with it being cut off, we contem- IMPERIAL DEFENCE. 27 plate its certain fall. We cannot, in short, admit such a contingency as Gibraltar, Malta, Bermuda, Hong Kong, Aden, or Singapore, being cut ofE from the rest of the Empire, and obliged to defend themselves when sur- rounded by the enemy. We contemplate their certain fall when we do this. We accept a return to the conditions I have spoken of as existing in the East and West Indies at one time, and as existing in the Mediterranean when we allowed Gibraltar to be bombarded, Minorca to fall twice, and Corsica and Elba to pass out of our hands. This sort of condition was all very well when, at the end of each year, we were able to balance accounts with the enemy in the matter of ships and territories captured by each nation. There was nothing vital about it, and no ruin involved on either aide. It was all an afEair of pawns, very interesting and exciting, as ultimately pre- paring for the check-mate which might be given by the gainer, but which was not, because of the fulness of the chapter of accidents, at all a certainty. Now, these changes in the possession of territories mean not only losses to the Empire which holds them, but stoppage of circulation and paralysis in the limbs of a delicate and extremely sensitive imperial body. Nothing was certain, nothing absolute, in saiUng naval war. In steam war all is absolute and certain ; time, supply, and force, if care is taken in the comparison. If coal were now as easily procured as water was then, and if the taking of water then meant that someone else was deprived of it, as is the case with coal now, we might be better able to afiord a disputed command of the sea in the vicinity of our ports of supply. Being as we are, dependent generally on coal that has to be carried across the sea, we must not only guard it in store but when, proceeding to stora Rightly 28 ESSAYS ON NAVAL DEFENCE, as we may, and do, regard the defence of the store as an all- important matter, we mast not forget that it is no use defending an empty store, and this we should be constantly doing if we guarded tho place of deposit and then left it. In the days of disputed command of the sea of which I am speaking, our water could be picked up in most places, our victuallers and store-ships were only required at long in- tervals, and the interception of them by the enemy had none of the certainties of time and place which now sur- round their possible capture. Let us look for a moment at what happens when disputed command of the sea is allowed. When Rodney got to Bar- badoes in February, 1780, he found De Guiohen blockading a British squadron in St. Lucia, and preparing to attack the island. Rodney's appearance sufficed to relieve it. Then followed an indecisive battle, and the British destroyed Fort St. Juan. Later, Rodney, reinforced, took St. EUstatia, Demerara, and Essequibo. Then the French were rein- forced and British territorial attacks had to be given up. There was another indecisive fleet action, and the French renewed their attempts on St. Lucia, captured Tobago, St. Kitts, Montserrat, and re-captured St. Eustatia, Demerara, and Essequibo, so that the British were left in possession of only Barbadoes, Jamaica, St. Lucia, and Antigua. Bat all this interchange of possession ceased after Rodney's action, which gave to the British the un- disputed command of the sea. So in the East Indies. The five battles between Hughes and Suffren were sufficient indication that neither was master, and accordingly each, as opportunity ofiered for a local command due to the wind, made such territorial attacks as time admitted. Hughes co-operated with the army in attacks on Negn.patam and Chinsura, and Imperial defence. 29 possessed himself of Trincomalee. SufEren, -watxjliing his chance, captured Cuddalore, and re-took Trincomalee, which he held till the peace. Thus we see always the same tale. If communications cannot be cut territories cannot be attacked. If communi- cations are cut and attacks made, territories will always fall if communications are not restored in time. Where ever it is necessary for us to keep up communications, we secure the place by the act. If we abandon the idea of uninterrupted comtaunications, then we embrace the idea of the certain fall of our territories. If we embrace the idea of uninterrupted communications, we dispense with that of assuming the necessity for very great local strength, and fall back on the immediate defence of our stored supplies, which need not include the defence of the sur- rounding localities, because our assumption is that sur- rounding localities cannot be attacked while our communi- cations are complete. We must not leave very important posts liable to capture by very inferior forces acting suddenly and by surprise. But we are not to suppose that any spot of our territory can hold out by itself with its sea communica- tions cut. We shall probably go fatally wrong, if we suppose that there is any real substitute for purely naval defence, or providing for the security of ingress to, and egress from, all our ports, whether fortified or not, and whether they be naval bases such as Portsmouth, Ply- mouth, Malta, Simon's Bay, Hong Kong, Bermuda, Halifax and Port Royal; commercial ports such as Liverpool, Newcastle, Cape Town, Durban, Bombay, Colombo, Cal- cutta, Melbourne, Sydney, or Brisbane ; or ports of com- mercial call, such as Gibraltar, Port Said, Suez, Aden, Singapore or Albany. 30 ESSAYS ON Naval dEfencJB. So long as we clearly understand that our fixed local defences are subordinate to, and assistant to, maintained lines of conimunication, and that purely naval force is never to be absent long enough to permit communication to be cut, we shall not allow much waste of money on what is not of the essence of imperial defence. But if we suppose that local fixed defences will relieve the Navy of any part of its historically defensive character, and assume that fixed defences are a real substitute for naval defence, and will either strengthen the Navy for purely offensive warfare or enable us to maintain a less complete fleet, then it should seem that we are not reading at all, or not reading aright, the teachings of naval history. ai CHAPTER II.

But I conceive that, willingly or unwillingly, any essayist who attempts to deal with the matter presented to him, must do so on the prescribed lines. He must be as full as the limited space at his disposal will admit ; he must be as complete as his knowledge allows ; and he must deal with his subiect according to the classification of its component parts which is furnished for his guidance. I shall therefore endeavour to let these rules govern the observations contained in the following pages. 1 Written in 1877. 32 ESSAYS ON NAVAL DEFENCE. It is, perhaps, so far fortunate that these limits of classi- fication have been drawn ; for were " the development of the maritime power of Great Britain" left without note or comment, as the subject of the essay, the views of the competitors might turn out so various and so contradictory, that an undue pressure would be placed on the shoulders of the judges, even if any really useful result were achieved. But on the other hand, an essay would never be complete which failed at the outset to grasp its subject as a whole, and to announce with what central figure the subordinate groups were to combine, in order that the picture might charm the eye with its beauty, and the sense with its truth. My conviction is that, in considerin point out that I have made a very close examination of the economical results of sail power, as applied to an iron- clad through two years' service, and to a gun- vessel through some fifteen months. I should state that the ironclad had a sail area equal to four square feet per ton of displacement, while the gun-vessel had sixteen square feet. As to the ironclad, I found, I think beyond the possibility of doubt, that her masts and sails cost the country, partly in coal 1 It will be clearly seen that up to this point I have done little more than amplify the views of Captain J. C. R. Colomb on " Im- perial Defence," taking — as I am bound to do— the more naval view of the question. THE DEVELOPMENT OF NAVAL POWER. 69 partly in wear and tear, and partly in interest on capital, not less than £2,000 a-year over and above what the ship would have cost had she been entirely mastless. A.S regards the gun-vessel, I traced her minutely over a voyage of 6,100 miles, of which only 1,800 were done under steam, with or without sail, and 4,300 were done under sail alone. The wind was fair and strong for more than seven-tenths of the voyage, and the foul winds never exceeded the force of five. Under such circumstances, the resort to sail only, delayed her voyage by about fourteen per cent. Supposing she had had no masts or sails, that the fair wind would not help her in any way, and that the masts and sails as exist- ing did not in any way retard her when the wind was foul, then it is possible to say that this ship, while reducing her speed as above, did actually save sixty per cent, of her coal on this particular passage, so very favourable to such result. Bttt being here concerned with the money cost, we must ask several questions. Suppose the ship, even as she stood, had steamed at the reduced speed forced on her by the resort to sail, would she not have made a probable saving? Can we truly say that fair winds, even without any sail, do not make an economy on coal ? Is it not true that masts and yards do in fact greatly retard a ship when steaming against foul winds ? What was the cost in wear and tear, and interest, of the sail power ? Lastly, this ship had -3 of light foul winds to -7 of strong fair winds j suppose we allow "1 for the difference of force, and say that she had •2 foul to -8 fair winds ; and suppose we strike a proportion, allowing that a ship must expect as much foul as fair wind, what shall we get as the result? To answer the last question, and the rest with it, we get her average gross saving at no more than thirty seven per cent., from which we must deduct the loss due to foul winds acting on masts 70 ESSAYS ON NAVAL DEFENCE. and yards, and the gain due to fair winds acting on a mast- less hull, as well as the probable saving due to the reduced speed. When I followed this gun-vessel to conditions where fairer averages may be taken, I got a gross saving of coal, without any per contras whatever, such as I have noted above, of five jxr cent. only. In this case the struggle to make a steamer a sailing ship, or a sailing ship a steamer, whichever way it may be looked at, has resulted in a ship very helpless indeed under all circumstances requiring propulsive power. Space does not permit me to go more into this question at present ; I have brought this forward to throw the onus probandi on those who differ from me.l So far, I have got at two conclusions ; our war ships must offer defence at sea, and they must Lave each a coal supply equal to 4,000 miles steaming at five knots, while their sail power is to be reduced to a pure auxiliary.- 1 have now to consider how ships may be made most capable of offering this defence at sea, and I shall best do this by considering something of the classification of war ship.s. In the first in- stance, what induces classification at all, and what classification is best suited to British requirements ? There always have been classes of ships, for the simple reason that it would have been uneconomical to have built but a single class. In the great naval epochs of the past, the classification was almost rigid. The line-of-battle ship, the frigate, and the sloop, formed the three great divisions into which all navies were then classed. The more technical " rate " then, as now, sub-divided all classes of ships abo.ve the sloop, but the ^ Wbtther these arguments were good or bad, the conclusion has certainly been in accordance with them, sail having disappeared from the Navy. — Ed. '-' Speed in comparison to coal consumption has so much increased, that the rate called for is now generally put at ten knots instead of five. But It is obvious that the principle has been accepted and maintain ed. — Ed. fHE DEVELOPMENT OF NAVAL POWER. 7l " rate,'' though it meant more than it now does, was not so complete a classifier as the terms used above. To-day the classification has very much broken down. We have the ironclad, the frigate, the corvette, the gun-vessel, and the gun-boat, as the neuclei of a possible classification ; but " classification " as a part of a settled naval policy does not exist. One of the most prominent results of the older classification was an agreement among nations that each class of ship was designed to fight her fellows; one of the results of the present, perhaps unavoidable, want of classi- fication, is that there is an idea that any ship should be ready to attack any other. Purely naval opinion is clear enough, that the old system was right ; but public writers of power and influence are not wanting to say that naval opinion, in this instance, is wrong. Yet nothing has occurred as yet to shake the lesson of history on this point, and naval opinion is so far right to rest upon it. The economical results of a happy classification will be admitted on all hands ; but those who have been in power have feared that with our present knowledge of the new naval forces and weapons daily growing up, any classification is as likely to be unliappy as to be happy. France is quoted against a classification, but I think when she produced many ironclads — or earlier, when she produced many paddle steam-frigates — of a particular type, she got a good econo- mical result for the time, and the ships she built with an eye to classification are not more obsolete than those which we bailt without an eye to classification. Names will help us much on a matter of this kind, and so far as I can see, we should do well to adopt a simple nomenclature which would have the double effect of steadying our view, and of giving us an easy way of speaking of war ships. The term "ironclad " is after all a fallacious one, as there is as yet no 72 ESSAYS OK NAVAL DEFENCE. settled system of placing the armonr, nor any regulated allowance of its thickness or quantity. But all ironclads, whether large or small, whether with much or with little plating, are now expected to fight all other ironclads, whether success be probable or no. Most ironclads will assemble in fleets, as they do at this moment, and I should propose to call that class of ship which represents the old line-of-battle ship in this matter — a " Fleet-ship." Then I see no reason why the next class should not retain the name of " Frigate," the next " Corvette," the next " Sloop," and the last " Gun-boat." " Sloop " is a fine old name, without at present any home ; I do not see why it should not take in all Her Majesty's ships commanded by commanders, and find a home there. I suppose there will still be " Dispatch vessels," "Torpedo-boats," "Rams," &o., but these in my view are temporary and insignificant, and I leave them out of my scheme. Under these five classes I should range, as best I could, the existing Royal Navy, and all future ships should be designed to more and more nearly approach the ideal uniformity typified by the classification adopted. Before I go farther, I should point out that the " gun-boat" will he practically left out of my general scheme. Such vessels are more weapons of attack than of defence, they are quickly built and would always be prepared with reference to special localities and particular duties. The few employed in peace time have fields of operation in guarding those very minute commercial rivulets which flow up shallow waters in various parts of the world; and in war time their defen- sive powers would still be similarly engaged ; they would never be expected to patrol the greater channels of com- mercial intercourse.! Taking first therefore the " Fleet-ship," I am prepared * It is a little difficult now to believe that fifteen years ago THE DEVELOPMENT OF NAVAL POWER. 73 to say that she should be a broadside ironclad of moderate dimensions, of moderate gun-power, and with a moderate thickness of armour. I say this with a full knowledge of all the shafts levelled at such ships, and in full view of the modern gun, the ram, and the three classes of torpedo ; and I am prepared, I think, to show that " power and economy" to use the excellent words of the Council, are not to be got for the Fleet-ship, but out of this type. The touchstone of the whole matter is to be found in this combination of economy with power ; because, as a moment's reflection shows, uneconomical power is not power in the true sense of the word. In approaching the question, a fixed sum of money m^ust be assumed to be spent in a given time. The most powerful single ship which can be produced for this sum of money is not necessarily the most powerful naval force which the money can command. It is only so if the same money will produce nothing capable of matching her except a sister vessel. Nor would it be economical to pro- duce such a single ship if she were so vastly superior to every other, that nothing could face her singly. The question would arise, whether she could be where she was wanted at the time she was wanted, or whether two or more ships could not be .built which — only costing a like sum — would be as much superior to her when combined as she was to any former single ship. The drift of this argument is in part perceived by those numerous writers who assert the demise of armour-plating and who see in the Chinese " Gamma " and " Delta " the there was no classification of our ships. It was first introduced in 1887 and now comprises (I) Battle-ship=, three classes; (2)' Cruisers, three classes ; (3) Sloops ; (i) Gun-vessels ; (5) Gun-boats, three classes ; (6) Special vessels. It is a classification which will bear compression, and the mere fact of adopting it tends that way. The gun-vessel appears to be dropping out. — Eb. 74 ESSAYS ON NAVAL DEFKt^CE. answer to the "Inflexible."! They are quite right so far as they go, but they do not carry their argument suffi- ciently far. The "Inflexible" was an answer to the Italian " Dandolo," but was not an economical answer. If the " Inflexible " mounts only four 80-ton guns at a cost of £500,000, and if the "Gamma " mounts a 38-ton gun which she can fight at sea, at a cost of only £25,000, it is pretty certain that so far as gun-power is concerned, the " Inflexible " is neither powerful nor economical. But then if this is admitted, we cannot stop with the writers alluded to, at the " Gamma ; " as the type of future gun-ship. The " Gamma's " fire from her one gun is slow, and not more certain than that of much smaller guns. If all nations now took to building " Gammas," it would very soon be dis- covered that the occupation of the 38-ton gun, as well as of all heavier, and some lighter types, was gone ! No one in his sober senses would build and arm a " Gamma " to fight another "Gamma;" or if he had already committed himself to the ship, he would speedily alter her armament, and substitute several lighter guns for the single heavy one carried by his opponent. Thus the "Dandolo " destroys herself and her guns together, by producing the " Gamma " — a statement which, to many persons, will appear to say that we are in a vicious, circular style of argument in the matter of guns and armour. I, however, am assured that the "Dandolo" with her 100-ton .guns and her heavy plating, forms one extren-.e, and the " Gamma " the other, of a system of experimental argument, which will bring us all to a happy mean between them. When you have a ship which, costing a certain sum, is able to successfully defend herself against two or more ships costing together 1 Vide Mr. Brassey, in the Times of 30lh May, 1877. THE DEVELOfMEXT OF JCAVAL POWEH. 7o the same sum, all by the use of guns and armour, then, so far as guns and armour alone are concerned, that type is permanent. If the " Inflexible " or " Dandolo " could reply, gun for gun, to the number of " Gammas " which could be built for £500,000, it would not be so easy to condemn her as opposed to a fleet of the latter class. It is because she can only reply to at best a very few of them that she shows as an uneconomical power. To regard- this question in its true light, it must be remembered that againsi guns there are two kinds of defence — resistance, ofiered by armour, and avoidance, offered by a small target. The " Inflexible " is the extreme representative of the former ; and the " Gamma " of the latter. If defence by resistance is offered, the attack can only meet it by increasing the weight and space occupied by the guns ; as both of these are limited afloat, the numbers of guns carried by the attack are limited and controlled by the strength of armour offered in defence. Armour- plating has in my opinion no other function than this. Invulnerability can never, I think, be attained. If, how- ever, defence by avoidance is offered, then the attack reduces the size of its guns, in order to increase their num- ber. It would be paradoxical to assert it as a fact, but it is well to contemplate the possibility of very heavy armour, combined with only numerous light guns in a single ship. It is quite true that such a ship would be comparatively in- offensive when attacking an ironclad, but what would the ironclad do with her guns which enly just pierced under very favourable conditions ; and what again would the ideal unarmoured ship with only a few guns do against the other's many ? But passing this by, we see that by carry- ing armour you compel your enemy to take few shots at you in any given time ; while if you carry a greater number of 76 ESSAYS ON NAVAL DEFJ!;^fCli. effective guns than he does, you compel him eitlier to in- crease his armour so as to reduce the number of your guns, or else compel him to abandon armour altogether. He can, as we have seen, only do this by a more or less near approach to the " Gamma " idea, and if it is more costly to put afloat in " Gammas " a number of guns equal to those lighter ones with which you are prepared to meet them, your guns being numerous, then he has no resource except to build, armour, and arm, a ship of the same type as yours, and so fight it out with similar weapons on equal terms. This is the argument as regards guns and armour, and to me it is as clear as daylight that on these grounds the heavy gun will remain, and that the ironclad will re- main, but I doubt about the very heavy gun, and the very heavy armour. I do not think that there is as yet anything in the ram or torpedo to alter this prediction. It is impossible on the data available outside the Admiralty, to say exactly whereabouts this medium between the " Inflexible " and the "Gamma" will lie, but as it is necessary for me to assume a medium in terms of English armour and guns, I take it at the 18 to 25-ton gun, and from 10 to 12 inches of the present armour plating. As to the latter I must express a firm conviction of very old standing, that practically little has been done in the matter of armour for ships. I think that by the use of steel, of chilled iron, or by discoveries in the distribution of armour, or of all combined, its resisting power for a given weight will be probably much increased, whereas I do not see that the effective power of the gun is capable of very material increase irrespective of increased size and weight.l The only point I make in the above selection is a security that my Fleet-ship cannot be success- ' I am struck by the ooinoidence that I correct the proof of this page on my return from witnessing the absolute triumph of the Harvey armour-plate over the B-in. gun. — Ed. THE DE\'ELOPMEXT OF NAVAL POWER. 77 fully attacked by guns of less power tliaii the English 18- ton gun, and that this gun to be efEective must engage her at less than 800 yards. These are moderate desires, and quite within our compass, and I suspect that such ships cannot be economically and successfully attacked with guns except by ships of like nature ; but this will appear later on. For the Fleet-ship we have thus got four of her chief elements : namely, (1) a coal-carrying capacity equal to 4,000 miles at 5 knots ; (3) a rig absolutely auxiliary ; (3) 18-ton to 25-ton guns ; and (4) 10-inch to 12-inch armour. If it is at this stage alleged against me that a single "Dandolo '' coming am^ongst my fleet of moderately strong ironclads must put them to flight, as her armour is imper- vious to their guns, then I answer that to float a " Dandolo " my enemies must have long time and preparation ; I will suspend the building of one or more of my Fleet-ships when the time comes, in order to build at a less cost than that of the " Dandolo," and in a much shorter time, a sufficient number of " Gammas " to master her. This is setting aside what I might do with my moderate ironclads themselves in the way of rams and torpedoes.l In every class of war ship I think a great principle should, as far as possible, govern construction. This is the principle of dudlUy ; everything should, when possible, be doubled, in order that the disorganisation or destruction of one part should still leave the fellow of it efficient and ready. No single chance shot, chance blow, chance acci- dent, ought to utterly paralyse the ship ; she should, to the fullest possible extent, be provided with a second item ' This formed, and still forms, the argnment against the very heavy gan and the very large battle-ships. I see nothing to alter lu it, but believe it will receive more general acceptance now than it did when written. I believe it is generally agreed that it would have betn better had the arguments prevailed. — Ed. 78 ESSAYS ON NAVAL DEFENCE. to fall back upon should the first be destroyed. Thus, for the Fleet-ship, she should be double below water — a ship within a ship — in order to allow her outer skin to be pierced without admitting water to the ship proper. In her compartments they should be so arranged that no two of them would sink her when filled. Her engines should be double, with a double set of boiler? — each engine being capable of connection or disconnection with each set of boilers, or with all or any of them. The two sets of boilers should be in separate compartments, and if possible, one compartment should be before, and one abaft the engines. The engines themselves should be each in a separate com- partment. The screws would of course be twin, and, I think, might well have gearing connecting each with the other when desired, so that one engine could work both in case of the other being disabled. But the greatest applica- tion of the dual principle should be in the gun armament of the Fleet-ship. This should be double : a heavy arma- ment to meet armour, and a light one to meet " Gammas," torpedo vessels, and all other unarmoured ships. The heavy battery should be divided into two, so that a great disaster in one half battery will not affect the other. I should carry this duality to very great lengths in the larger ships. There should be two steam fire engines, each to do the duty of bilge-pumps and capstan engines, and the two capstans should be capable when manned of taking tho place of the steam fire engines. The whole, and half the pumping power should be capable of acting on any single compart- ment, and a double set of pipes would make the danger of accident twice as remote. In the smaller classes of ships the dual principle could not be carried so far, but I suspect it might go farther than we think for.l ' I still hold to this principle of duality. — Ed. THE DEVELOPMENT OF NAVAL POWER, 79 When sketching out the great principles which should govern construction in an ideal English Navy as a defensive force, I have to remember that it is to repel the gun, the ram, or the torpedo with success, and it is time that I should write the general principles I propose to adopt for these purposes. I have already mentioned the two species of defence against guns, namely, resistance and avoidance, and these also avail us against rams and torpedoes, though not perhaps to a like extent as against guns. I think each species of defence should be employed in every case. As against the gun, I propose to use armour for resistance, and to reduce the size of the vital target to the smallest limits. I am strongly disposed to think that I would not confine armour to the fleet-ship, but would employ it to a limited extent in the frigate. In the placing of this armour, I should follow a dictum on which we are all pretty well agreed now, although the principle does not appear in all past types of ironclads, namely, that the ship should be pro- tected first, and then the guns— or rather, and then the men. As proper systems of compartments do in fact offer great protection to the ship, it does not necessarily follow that all, or even the greater part of the armour should offer no protection to the guns ; on the contrary, I think it is only where compartments are absent that guns should be without resisting protection, and I can conceive a cellular hull without armour, carrying an armoured battery of guns, with much prospect of success in action. But the Tleet- ship, and perhaps the Frigate, would in my scheme have their water lines and their batteries both protected by armour, but its disposition will differ from any which has to my knowledge been as yet proposed. For the defence against Rams, I offer in the first place the avoidance by manoeuvring, but I am not prepared to incommode my coal 80 ESSAYS 0\ NAVAL DEFENCE. stowage already fixed on, by any shortening of the ship for manoeuvring purposes. I am quite ready to condemn ex- cessive length for the attainment of excessive speed, but I must have my 4,000 miles of steaming power whatever be the consequence in length. I am strongly disposed to think, however, that a ship may often avoid a fatal crushing in her side by opposing resistance to it. With plating arranged as in the " Devastation" target of May, 1871, in two thicknesses, it is possible to back the butts of two plates by the centre of a third ; if this vertical structure is again backed by a horizontal angle-iron or feather such as an iron deck represents, it would have great resisting power, and with an inner skin behind it might be successful against a Bam. But if the great principle of duality, as applied to compartments, be adopted, I do not see how a single Bam is to inflict fatal injury, and I would risk it. For defence against the torpedo, I rely very much on avoidance. The course of investigation into the torpedo question has not been, so far as public knowledge goes, to raise that weapon in naval esteem. As a harbour defence I have for the present nothing to say to it, but as a sea attack, with which I am now alone concerned, the Whitehead is the only species which is seriously feared. Eeasoning from analogy, I should think it fair to suppose that the fear of the weapon will not increase as it becomes familiar to the Navy, and as those weaknesses which exist in every new invention are brought into view. But when all this is said, the weapon cannot be ignored, and the only defence of resistance that I know of is a proper system of compartments. If a ship is prepared to stand one exploding Whitehead without sink- ing, I suppose her to have used her defence by resistance to the utmost, and this she may attain by taking care that no two compartments when filled will sink her. THE DEVELOPMENT OF NAVAL POWER. 81 Thus far, for the purely defensive arrangements of a purely defensive British Fleet. But a defensive fleet is not necessarily inoffensive ; on the contrary ; much of its defence must rely on. the fear of its enemies to attack. With what weapons is the fear to be established, and how are these weapons to be disposed ? I have already committed myself to the gun, up to the moderate weight of 25 tons, and I have already claimed its disposition on this broadside as the best. To me it is an astonishing question which is com- monly put — " Whether is the bow or the broadside the most important fire ? " because I have never heard a serious argument in favour of the bow fire. I know that an opinion in its favour exists, or is supposed to exist, because in a great many ships the broadside is weakened, and very many terrible inconveniences and dangers submitted to in order to supply bow fire. But I have only heard it asserted in support of this policy, that as a ship must not expose herself to be rammed, she must be prepared to fight an end-on battle. But unless she is pretty close to her enemy, and in a particular relative position, there is no objection in life to her presenting her broadside, and an end-on battle must become a broadside one after the lapse of a very few minutes. But here again, the question is one of fact, not opinion. It is certain, because a ship is longer than she is broad, that the broadside fire can always be made more powerful than the bow fire. It is also certain that the vertical target presented by a ship end-on is less than that presented by a ship broadside-on. I have examined the firing of some of our ships provided with bow fire, and find that bow guns of an average ship throw away 26 per cent, of their fire, under conditions when the broadside guns of the same ship only throw away 16 per cent, of their fire. But the idea of bow and stern fire has not a 82 ESSAYS ON NAVAL DEFENCE. grown up, as we generally suppose, on reasoned ground ; wc have been drawn into it by an historical process. Bow and stern chasers were in old days, and may be now, re- garded as useful adjuncts to a ship's armament, and there- fore there was always that idea to rest upon. The paddle-wheel occupying the space required for broadside guns, drove them to the bow and stern. As there was little space there, an increase in the power of the " pivot guns " was sought as a substitute for their necessary reduction in number. Screw ships found the pivot-gun already established, and adopted it as their long-range weapon of attack. The naval mind was thus familiarised with the idea of " all-round fire." The two merits of the turret ship, as originally proposed, were its entirely ar- moured condition and its " all-round fire." There was a tendency to show that other arrangements besides the turret could develop " all round fire,'' — so we got ships with guns placed ill for broadside fire, but well for bow or stern five. And having such guns, controversy arose as to their relative values. It was never seen that to make all-round fire important was the natural aim of those who supported the turret system, but that it was, with the screw ship in motion, and especially with the twin-screw ship, a matter of less vital importance. When it was as easy to turn the ship as the turret, why lay such stress upon the arc of training ? In the result, the great merit of all-round fire was given up, and the supporters of turrets — having already given up complete plating — claimed for turrets — a claim they still support — the power of mounting heavier ord- nance than any other system. But meantime we had got the special end-on, and the special broadside fire into a good many ships — the real history of birth was forgotten — and ancestors were found for each kind of fire in questions of THE DEVELOPMENT OF NAVAL POWER. 83 tactics which were practically younger than the ships themselves. Oa such grounds I throw over without fear the " end-on " fire ; I decline to weaken the broadside for an advantage so problematical, and I prefer to be very strong in the directions where my strength would most naturally develop itself, to making myself everywhere weak. I am certain that my enemy must either fly, or let me get my broadside to bear on him, but I do not know any means of making him fight an end-on action if he does not choose to do so. I have, however, no objection to a light end-on fire as an adjunct to the heavy broadside fire ; and I think that if the foremost and after guns of my heavy broadside battery can bear a little more forward and after training than the others, it will not be amiss, pro- vided it does not detract from the ordinary broadside power. Such is my present faith as to guns. As to the ram, I hardly know any class of ship to which I would not fit it. I am not so anxious for a " spur " proper, but I think that every class of ship ought to be able to ram her fellow without too much damage to herself, on any con- venient opportunity. I am not so well disposed towards the torpedo. I think that it is not impossible a tow- ing torpedo may be constructed worthy of a place in the armament of a defensive fleet-ship, but I have no belief whatever in the Harvey as a defensive weapon, and I ex- clude it without hesitation from my scheme. I have much more faith in the " outrigger," but as I hinted in the early ' pages of this paper, it appears to be the proper weapon of a blockaded, not of a blockading or patrolling force. There remains the locomotive torpedo, of which the Whitehead is the most celebrated illustration. If I leave this weapon out of my scheme, I must not be understood as rejecting it, but it is too young, too little known, and too untried a 3 84 ESSAYS ON NAVAL DEFENCE. to take a place in a scteme which boasts of being founded on fact.l I think that I have thus far marshalled and discussed all the great principles which should govern construction, and it now behoves me to show their practical application to the classes of ships I have suggested as proper for our Navy. I shall here give no more than an outline, because the explanation of several completed designs would be foreign to the purpose I assume to be held in view by the Council of the Institution. I do not suppose that all speci- mens of each class will ever be identical in all respects, but I consider that they should be as nearly so as the gradual development of improvement allows. I think there would probably be two divisions of the Fleet-ship class, the smaller for the more distant services, and the latter for blockade and fleet work nearer home. I should put the displace- ment of these ships at 8,000 and 6,000 tons respectively, and probably the one might be called on to mount 25-ton guns, and the other 18-ton guns. The Frigate would dis- place about 4,000 tons ; the Corvette 2,000 tons ; and the sloop from 600 to 1,000 tons. I shall now proceed to describe a second-class Fleet-ship according to my design, and in doing so will compare her with an existing type of her own displacement. Such a comparison is necessary to fix our ideas and to show the advantages gained by ad- hering to the principles I propose. The first-class Fleet-ship would be of the same type, but larger in every way, while the frigate would in many respects be a smaller Fleet-ship. The Corvette and the Sloop would differ in arrangement, but there would be between them a more complete sym- metry than exists just now. ^ This is the argument for holding to the old system of arming the broadside. All subsequent experience confirms me in it, and I thiiik I eee the change coming in accordance with it. — ^Ed. THE DEVELOPMENT OF NAVAL POWER. 85 The existing type of ship which I hare selected as my exemplar is the " Invincible " class, of which the displace- ment is 6,034 tons; the I.H.P. say, 4,500; the heavy armament ten 12-ton guns ; the light armament insignifi- cant ; the armour 8 inches thick to protect the vital ■ water-line, and not exceeding 6 inches elsewhere. The compartment arrangements are such that the two largest communicate by a supposed watertight door below water, and are together amply sufficient to sink the ship when full. The inner skin does not reach the water-line, nor even the deck below the water-line, so that a leak below the water-line lets the water directly into the body of the ship. The class carries some 460 tons of coal, 160 tons of masts and sails. The weight of the hull, including armour and backing, is 4,000 tons, and of the armour itself 900 tons. The plating extends 5 feet below the water-line, and to about 4 feet above it. It is connected by armour to that of the main battery, which carries six 12-ton guns, mounted as broadside guns, in the usual ports, and above this main battery is a central armoured upper battery, the guns in which are mounted to train from a fore and aft position to one exactly absam. The class is rather deficient in boiler power J and of course very deficient in coal stowage ; at five miles to the ton, which is probably their average steaming power at five knots in smooth water, the class has no more than 2,300 miles in their bunkers. Their area of plain sail is about 24,000 square feet, or about 4 square feet per ton of displacement ; and to enable the " Invincible " to carry this sail, she has 360 tons of ballast, otherwise use- less, and a drag upon her. The " Invincible " is thus, to my view, a second-class Fleet-ship. She has been designed to resist the attack of every gun of less power than our own 6J-ton 7-inch gun; 8t) Essays oN jstaval defence. which penetrates 6-inch plating at 400 yards. It is part of the design that a fatal wound cannot be given at the water-line by a gun of less power than the 12-ton. Some advantage has, however, been allowed to the compartmental arrangement, as a protection from the fatal effects of shot. As to the attacking powers of the design, immense, and to my view, undue advantage had been credited to fore and aft fire, and very great sacrifices have been made to protect the fore and aft guns by armour. In the first place, the area of side armour covering the main battery is 247 square feet per gun ; therefore to mount five guns on the broadside would cost 1,235 feet of armour, or 2,470 feet for the double broadside ; add to this the ends at 1,150 square feet, and we get 3,620 square feet as necessary to mount ten 12-ton guns in a single broadside battery. But to mount these guns as in the " Invincible," six on the broad- side, and four fore and aft, costs 4,445 square feet, or 825 feet more : or, taking the armour at 6 inches with 10 inches of backing, a weight of 102 tons. Besides the actual weight thus lost, the height of the upper battery induces weight by carrying the gunwale up to it ; and its moment above the centre of gravity has much to say to the necessity of ballast. The question therefore remains for those to answer who advocate the protected fore and aft fire, " Are you prepared to spend 1 00 tons of weight on it, when the whole of your heavy armament costs you but 300 tons ? Is it better to increase your heavy armament by one-third, or to spend the weight in placing some of your guns so as to fire in a line with the keel ? " In designing the propulsion of the "Invincible," the con- clusion has been that coal supply is less important than sail power, and practically it is seen that it has been considered wise to spend 526 tons of weight on the development of Bail The DEMfiLOPMEXT OF XAVAL POAVER. 87 power. I say nothing of the actual performances of the class under sail, for it may be an accident if they are not proficient in that respect. Now, it may be observed that in the case of a second- class Fleet-ship of 6,000 tons, I am prepared to advise a certain trusting to the compartmental system for the pro- tection of the ship ; that I do not think it is wise to spend 100 tons of weight on obtaining a protected fore and aft fire ; and that I do not think it is wise to spend anything at all approaching 526 tons on the development of sail power. I propose, in placing my views in the concrete, to take the lines of the " Invincible " below water as a fixed standard to work upon, and I propose very little alteration in her outward form above water, and practically none in her construction. In this way every proposed alteration will have a measure, or 'standard of comparison, and the rough outlines of my design may be criticised by an appeal to existing facts. It is necessary for me to state that as I have only collected the main points of the " Invincible's '' design here and there, and by calculation and inference therefrom, my figures must in no case be thought rigidly accurate. In a paper of this kind, I have thought that a reasonable accuracy is all that is required. Turning now to Plate II,, we have before us the profile or elevation of my design for a second-class Fleet-ship to supply the place, say of the lost " Vanguard." In the design, the bow and stern above water are both thrown in a little to make up for the placing of certain weights on the extremes of the upper deck, which are not present in the " Invincible." A light poop coming forward 47 feet is added, as a set-off against the removal of the deck above the " Invincible's " upper battery. The whole of the gunwale fore and aft is lowered 88 ESSAYS ON NAVAL DEFENCE. 2 feet, and the removal of this weight may be taken as margin to cover deficiencies ; otherwise the exterior of the " Invincible'B " hull is practically unaltered. In the " Invincible " the lower deck is 2 feet 6 inches below the water-line, and in the " Outrageous " this deck is carried up 3 feet, to 6 inches above the water-line. Below this deck the " Outrageous " is divided into nine main water- tight compartments. The distance from No. 1 to No. 8 bulkhead is the same as in the " Invincible," but between these there are in the " Invincible " but four main compart- ments — compartments, that is, with bulkheads carried up to or above the water-line. In the " Outrageous " there are at least seven. In both " Invincible " and " Outrageous " the double bottom extends from No- 1 to No 8 bulkhead ; in " Outrageous " this double bottom is carried up to the lower deck ; in the " Invincible " it stops short 5 feet below the water-line, but in the " Invincible " it is 4 feet 10 inches wide at that point, whereas in the " Outrageous " it nowhere exceeds 3 feet 6 inches, The main deck of the " Out- rageous" is 7 feet 10 inches above the lower deck, which gives a height of 6 feet 6 inches below the beams on the lower deck before and abaft the the battery, and of 5 feet 8 inches under the battery itself. The main deck is 7 feet 7 inches from deck to upper deck, or 6 feet 6 inches under the beams. This may be thought low for the 18-ton guns I propose to put in the battery, but I see no reason why the axes of the guns should not be brought down in mounting, and 6 feet 6 inches will allow 10° elevation and 10° depression even to the 35-ton gun. It is most important to reduce the area of plating, and the consequent exposure of the men under iti The upper deck gunwale is 4 feet 6 inches high, repre- senting a parapet to admit of rifle fire over it. As compared 5 E 3 "T" =] D D -rl ■i^. e THE DEVELOPMENT OF NAVAL POWER. 89 with the " Invincible," the main deck of " Outrageous " is 2 feet 7 inches higher above water than her main battery deck, and the centre of midship port of " Outrageous "is 11 feet 2 inches above the water-line, while that of " In- vincible" is 9 feet 10 inches. Tho upper deck of "Outrageous" is thus raised above water 7 inches more than that of " Invincible," and this statement concludes all that is necessary to say of the general structure of the pro- posed ship. I may say here that in proposing these changes, I am not forgetting either weights or moments, but as to the former, the simple raising of the decks does not increase them, and additional bulkheads, &c., are made np for by the removal of others. I come now to my arrangements below water, and my explanations will refer to Plate III. as well as to Plate II. The ends before and abaft the main compartments may very well stand as they are ; the usual arrangement of sub- divisional compartments properly tight, and without the treacherous but common sluice valves, ought to make the ends reasonably secure, so far as they go. The first com' partment counting from forward in both ships would con- tain water, hemp cables, &o., and perhaps chain cables ; though in " Outrageous " I might possibly stow them else-- where with advantage. In the second compartment are 4 boilers and 20 furnaces, two-thirds of the whole boiler power of the ship. In the " Invincible " the whole boiler power is in this compartment, and this traverses the great "dual principle" to which I have committed myself. This compartment in " Outrageous " likewise contains, in round numbers, 300 tons of coal stowed at the backs and ends of the boilers. The third compartment contains the magazines, which occupy the whole of the compartment in a fore and aft direction, and to within 4 feet of the inner 90 Essays on naval defence. skin transversely. The crown is the same distance below water as that of " Invincible." Coal is stowed as a reserve above the crown of the magazines, and in the wing spaces. The magazines are two in number, divided by a fore and aft bulkhead ; each has three passages, which are lighted through No. 4 bulkhead from the engine room. The handing rooms are on the fore side, and each has two supply scuttles, and one return. The supply is prelected from the lower to the main deck by a wrought iron cylinder 3 inches thick, so that bursting shell, or light shot, shall in no way interfere with it ; and as the supply is direct to the battery, much less labour is involved in it. Passing to the fourth compartment, we come to the engines, which I assume would be compound in the new ship. In the " Invincible " the engines are together, but in the " Oatrageous " I propose to separate them by a fore and aft watertight bulkhead — still following out my principles. Abaft the engines is No. 5 compartment, which contains two boilers, each of five furnaces, placed athwartships between the shafts, with 140 tons of coal stowed behind them in each wing. In the " Invincible " this compart- ment takes the engines, but I prefer, as I have said, to liave some boiler power abaft, as well as before the engines, so that there shall be a double system of communication between the engines and their prime mover. But now, as the space at my disposal for engines, magazines, and boilers, from No. 2 to No. 6 bulkheads, is exactly the same in " Invincible " and " Outrageous," it may well be asked how I am able to put into it boiler power to 30 furnaces against the " Invincible's " 26 ; coal to very much over 600 tons, against the " Invincible's " 460, and power to the extent of 56 tons, against 30 carried by the " Invin- cible ? " The answer is simple enough. THE DEVBLOPMEXT OF XAVAL POWER. 91 I have rid my ship of light rooms, of a wasted passage, and of a shell room, and beside this the compartments are everywhere higher. As to the shell room : so soon as it was admitted that shell may be carried in the open, there was an end to shell rooms, and I have properly left the whole of the shell to be stowed as convenience dictates. The after compartments, as in the-case of those forward already spoken of, might remain as in " Invincible " for the stowage of water and provisions. Ascending now from the holds to the lower deck, the observer would find it clear fore and aft, except as to cabins extending along each side. Unlike the "Invincible," there are no watertight bulkheads with assumed watertight doors, and the deck is comparatively lofty, except under the battery. But though there are no bulkheads, a reserve of buoyancy is got in a much more really secure way. The main bulk- heads are prolonged for 2 feet above the deck, so that water cannot ilow freely beyond them. As to convenience, these are readily stepped over ; and as to safety, no errors or neglect of those on board can mar their good effects in time of trial. I may here observe that I have always thoroughly distrusted appliances such as watertight doors, sluice valves, Vide U.S.I. Journal, vol. xxv, p. 316 THE NAVAL DEFENCES OF THE UNITED KINGDOM. 147 the Federal method will always be an element of steam blockade. It may be that the coal question is more insuperable than it appears. But it is evident that if it is, which appears to me in the highest degree unlikely, all that it can possibly do is to throw us back from Lord St. Vincent's system of naval defence upon Lord Howe's system. How can we under either system get an enemy's ironclad fleet into the Channel, and free to bombard Portsmouth or Plymouth Dockyard, or to force the Thames, the Med way, or Harwich ? I think that the country has a right to call on those who are urging expenditure on the hypothesis of an enemy's ironclad fleet in command of the Channel to justify their hypothesis in some way, Nothing can be more un- businesslike than to spend money to meet a very improb- able contingency, and I venture to think that one which has not occurred for centuries is primd /ade improbable, and cannot be assumed. I want to put it to those authorities who are for spending this money, whether they accept the basis of naval defence as determined by Lord Howe or Lord St. Vincent, or whether they are prepared with another System, and if so, what it is ? I cannot accept at their hands the pre- liminary hypothesis of an insufficient fleet for any system of naval defence, for neither they, nor anyone else in the country, has formulated such a condition of things for acceptance. But I am willing that they should say we have not, or shall not have force enough to adopt Lord St. Vincent's method. But then I turn round at once and say, that there is nothing else for us to adopt but Lord Howe's method. If we cannot defend ourselves by masking the enemy's fleets in his ports, but yet have the superior naval force, L 2 148 ESSAYS ON NAVAL DEFENCE. what can we possibly do, being moderately sane, but con- centrate that superior force in a defensive attitude, and wait ? The ironclad squadron which is to bombard Ports- mouth must come out of some port. If we have not the power to prevent it from coming out of that port, and therefore cannot send our fleet there, can we — still being moderately sane — do anything else with our fleet but keep it at home, and ready ? And if the enemy's fleet is inferior, which by the hypothesis it is, how can it come and attack US ? The First Lord of the Admiralty uses a curious expres- sion in approval of spending the money in fortifications, which might otherwise come into his hands for the strengthening of the naval defence. He says the fortifying the home ports " must largely increase our ofEensive naval power, for the bases of operation from which our fleet can issue will require little or no naval defence." What meaning can we attach to these words in view of either of the systems of defence before us ? Would Lord Howe have agreed that because Portsmouth, Plymouth, and the Thames were strong, therefore he could dispense with his reserve fleet at St. Helen's, or take the grand fleet away to attack Eochefort ? Most assuredly not. What would become of our Channel commerce, what would hinder invasion, were he to leave the Channel open behind him ? How could he attack Rochefort with the Brest fleet free on his flank ? The strength or weakness of Portsmouth or Plymouth could not afEect in the slightest degree the necessities or the conduct of Lord Howe's system of defence. If that system succeeded, the fortifi- cations would not be necessary ; if it failed, the enemy would have an ample choice without thinking of Ports- mouth or Plymouth. THE NAVAL DEFENCES OF THE UNITED KINGDOM. 149 In a system of defence conducted on Lord St. Vincent's principles, the status of Portsmouth or Plymouth would be equally powerless to aid or control the action of the fleet. If the blockade succeeded, the fortifications would not be called in question ; if the blockade failed at any point, the evaded squadron must fall back on the Channel. In no case could a squadron proceed on an offensive ex- pedition leaving the territorial waters open to the enemy. The strategical error which underlies the whole demand for this vast and growing expenditure on fortifications and other fixed defences is of old standing, and I venture to think that we all shared in it — I am sure I did — a few years ago. I shall best bring it out by mentioning two utterances, one quoted by Sir Charles Dilke quite recently, and the other occurring in the discussion on General Oollinson's paper in 1874. The author whom Sir Charles Dilke quotes without disapproval, says that the state of the works at Plymouth and Portsmouth is such that in war we should probably withdraw two considerable por- tions of our fleet from the blockade of the enemy and place them at those two ports to prevent their reduction. The other observation fell from the then Captain, but now Colonel, Ardagh. He said : " It would be perfectly pre- posterous to employ an ironclad to defend a port when you could construct a fort at one-twentieth of the cost of the ironclad, and put one-sixth of the personnel into the fort to defend it." Setting aside the obvious slip of the intellect which befell the first writer when he forgot that a blockaded force was blockaded, and therefore could not attack Ports- mouth or Plymouth, and coming to his divided disposition of naval force to defend those ports, we can see how easy it is to go wrong. It is manifest, when we think of it, 150 ESSAYS ON NAVAL DEFENCE. that if there were force enough in ironclads at Plymouth to defend Plymouth, Portsmouth would not want any further defence except on the supposition, hardly capable of being made, that Portsmouth and Plymouth were attacked at the same time ; and that in no case would a naval strategist, having to defend Plymouth and Ports- mouth by ironclads, divide his force. And the same error, though it is not so close to the surface, was in Captain Ardagh's mind when he spoke as he did. In no case ought a naval strategist, having to defend the ports and coasts of these islands by naval means, to think of separate naval defence for separate ports when the attack is of a serious character and re- quiring time for its accomplishment. We have seen that this was well enough understood by our forefathers, even when the movements of ships were slow and of almost measureless uncertainty. It is ex- ceedingly singular that when we have ships of which the movement is both rapid and certain, we should have so clean forgotten it. And so we have Captain Ardagh stating a thesis which is entirely a wrong one as applied to the defences of these islands, but which we have all of us accepted over and over again as truth. Ton can defend a harbour, he says, in these islands, by fortification at one-twentieth of the cost of its defence by ironclads- This is no doubt true if the defence by iron- clads were like the defence by fortification and required separate constructions for each harbour. But it is the reverse of truth as matters stand. If on any line of coast of these kingdoms there were twenty ports, each port requiring to be defended by some- thing equal to a single ironclad, which plan would be the cheapest ? To build twenty forts, each equal to an iron- THE NAVAL DEFENCES OK THE UNITED KINGDOM. 151 clad in power, or to build one ironclad and station her in tbe middle of the line of coast ? Captain Ardagh might have argued that the construction and arming of the twenty forts would not have cost more than the construction and arming of the ironclad, but he admits that the forts would take three times as many men as the ironclad to man them. And again, when the first rough estimate put forward for defending our mercantile ports, not against ironclads, but only against cruisers, is given at over two millions, we may be confirmed in our doubts as to whether twenty forts, each equal to an ironclad, can be prepared and maintained for the cost of one. Into this same strategical error we seem to have fallen in .building the group of coast defence ironclads, and the coast defence gunboats. The idea was, and is, to distribute them at different ports ; and they were intended to be the answer, not to sporadic raiders, but to the ironclad squadron. But five or six ironclads of little locomotive and no sea-keeping power, distributed at different points, can only be a defence against a very limited strength of attack ; and on this point Captain Ardagh was perfectly sound in 1874. A much smaller number of ironclads of good locomotive power and good sea-keeping qualities, is a more powerful form of defence when concentrated at one point on our coast, con- nected up with the electric telegraph, and ready to act on any other point. The error we have fallen into arises, I believe, from forgetting that the strategy of the naval Power in command of the sea is necessarily diverse from that of the naval power which cannot hope to have it. France, in building coast defence ironclads and sta- tioning them at her great war ports, is pursuing a policy which can be supported by sound reasoning. Bach 152 ESSAYS ON NAVAL DEFENCE. of these ships is, in her place, the equivalent of a sea-going ironclad, and would compel the enemy, if he determined to blockade, to appear ofE the port with a sea-going ironclad for every coast defence ironclad within it, or to suffer the chances of a reverse. But the superior Navy cannot logic- ally contemplate or prepare for any other position than that of the superior Navy. If she does, every pound she spends on that assumption is so much subtracted from her own power, so much deliberately spent in encouraging inferior naval Powers to hope. There is nothing in history to show that there can be in steam naval wars those alternations of success and failure which existed in our sailing naval wars. There are no longer the uncertainties on which those alternations rested. Times and spaces which were then incalculable and might turn to the advantage first of one side and then of the other are now fixed and known. We sometimes speak in a vague sort of way, as a justifica- tion for the spending of millions on defences which are not naval, and pre-suppose naval failure, of what we are pleased to call Nelson's being " decoyed " to the West Indies. But if we came to chapter and verse about it, we should see that from no point of view does that action of Nelson's justify the inference drawn from it. In the first place there was no "decoy,"' in the proper sense of the word. If Villeneuve had pretended to go to the West Indies only, and had turned back into the Channel, leaving Nelson to pursue a false scent, there would have been something in the " decoy." But as it was. Nelson simply followed him all the way there and all the way back again, continuing the watch on him which he would have pursued had Villeneuve not quitted the Mediterranean, and masking his force throughout the proceedings. Not only bo, but when Villeneuve, after THE NAVAL DEFENCES OF THE UNITED KINGDOM. 153 forming his junction -with the ships at Ferrol, was ready to proceed up Channel, there was in front of him, oiS Brest, a full muster of the whole of our available force, including Nelson's ships. If, therefore, there was any danger to England from invasion at this juncture, it arose, not from any errors, mistakes, decoys, or evasions, but from the prosaic fact that the country had not provided a sufficient naval force for the work it had to do. Strategically, there was nothing novel or startling in that episode of naval war. There was a junction between some of the divisions of the enemy's force, which had often been completely carried out before, and was now only partially carried out in consequence of that very " decoy " which is generally supposed to have led up to its completion. Had Nelson never quitted the Mediterranean, then indeed Villeneuve might very possibly have gone on to Brest, for he would have been conscious of having shaken off Nelson's fleet. But as it was, when he sailed from Ferrol for the last time, he was certain that Nelson was near him (he was really two or three days' sail ahead of him), and was con- scious that, strategically, Napoleon's plans were a failure. How far this consciousness influenced his decision to retreat to Cadiz we cannot say, but we can say that it was certainly an element in enforcing that decision. So we come back again to the point from which we started, that there are before us two systems of naval defence for these islands, that of St. Vincent, which was also that of the Federals, a systematic and close blockade of the whole of the enemy's ports ; or Lord Howe's system, which assumes blockade to be impracticable, and concentrates the naval force at home in a defensive expectant attitude. Both systems assume a reserve fleet which would not be brought into action but upon the failure of the main fleets to prove 154 ESSAYS ON NAVAL DEFENCE. defensive. Coming back again to them, we have to repeat the request that those who are calling for the expenditure of money on defence which is not naval, and assumes naval failure, should show distinctly how and where the failure is likely to take place. I do not mean to deny that generally what has happened before in naval war may happen again, except where the use of steam power distinctly forbids it, as, for instance, the blockading fleet being blown off the coast as it used to be. But if it is once admitted that we can safely refer to history and experience, then I claim that we can rely on naval defence just as we used to do. But I think it is imperative on us to prepare to adopt St. Vincent's method, and that solely on account of our commerce. Draw a line in imagination from Cape Finisterre to Cape Clear, and consider that perhaps 9,000 British ships cross it either outward or homewardi bound every year, of a value only to be reckoned in hundreds of millions. Consider then that in the wars of the past, until the blockade system was in thorough working order, it was about this line that both sides made some of their heaviest captures. Ooasider too that Spain in the days of Queen Elissabeth checked her commerce as a measure of self- preservation ; that Holland stopped hers entirely for two wars with us ; and that Germany in our own time did the like. Consider that for the same reasons any naval opponent of ours would leave us no commerce to prey upon, and we can see that this line from Cape Finisterre to Cape Clear would be the scene of peculiar disasters to us without any compensatory advantages under a revival of Lord Howe's system of defence. When, in our earlier wars with France, the vohime of the commerce of each THE NAVAL DEFENCES OF THE UNITED KINGDOM. 155 country was so far equal that the captures were also nearly eqaal, the struggles over this line were pretty nearly equally productive and equally disastrous to each side. Now the disaster could only be on our side, and the pro- duce on the side of the enemy. In order to protect our- selves over this line, I see no means but a revival of convoy — which always was, and always must be of doubtful value alone — or a close blockade of the enemy's ports. It seems impossible to deny, in the face of American experience, that steam blockade, properly undertaken, is exceedingly efEective; perhaps if I mention that the number of steamers captured or destroyed by the Federals amounted to three- fifths of the whole number of steamers of 100 tons and upwards now possessed by France, it will serve to show what a tremendous engine that blockade was. There is therefore nothing so likely to protect the line and the free passage of our commerce as close blockade ; and close blockade on St. Vincent's system, with a reserve squadron at home, does away with all this waste in fixed defences. It appears to be clear that logically we have no right to spend the money we propose to spend. For if the blockade be eSective it is certain our coast cannot be insulted. If it be not effective it is incumbent on us to make it so in order to protect our commerce. There is no logical sequence in taking away money from blockade to spend it on forts and submarine mines, because if the blockade be so efiBcient as not to need it, it is certain the ports cannot be attacked ; and if the blockade be inefficient it is imperative to make it so. But if it cannot be made so, commerce must suffer, but the ports are no more open than before to attack, for the fl.eet must be concentrated at home on Lord Howe's system. I had intented to have gone pretty fully into the dangers 156 ESSAYS ON NAVAL DEFENCE. to which our shipping near at home, all round our coasts, and ofE our ports would still be liable even after all the greater measures of defence were completed. Time does not permit it, however, and I must only glance for a moment at the question. At times when Lord St. Vincent's method of naval defence was in full force, and when the enemy's war ships were hardly to be met with at sea, the systems on which our commerce was attacked changed, but the attack was still effective. The scene of the attack shifted from that great line we have been speaking of, and centred itself pretty well at Beaohy Head. There never were such swarms of privateers seen as were to be met in and about the Channel in 1810. We captured them by the score annually, but they captured our ships by the hundred. The mischief was no longer done by the great war ships such as the grand corsairs like Jean Bart, Dugnay Trouin, or Thurot, commanded. Such ships could not get through the blockade. Their places were taken by luggers and cutters and snows carrying only six or eight guns, but with plenty of men for boarding and forming prize crews. These " despicable craft," as contemporaries called them, were small enough to slip in and out of the French ports almost without let or hindrance, but they were found competent to face an Indiaman off the Bill of Portland. There was nothing stopped them. The more of them we captured the more they swarmed, and the Admiralty of that day, with more than 600 cruisers at their command, fairly admitted they were beaten. They had reason to confess, seeing that over 600 of our merchant ships were carried into the enemy's ports under our noses in one year. These excessive losses were in part due to a relaxation of St. Vincent's system off the smaller ports, which was deprecated by contemporary observers. But still in 1804, THE MAVAL DEFENCES OF THE UNITED KINGDOM. 157 when this was not the case, the captures of our ships ran up to 387. This is as much as to say that a very good blockade was not a perfect one. From the numerous small ports in France small i-aiders did manage to make exits, and the richness of the prizes justified the risks. Admitting, as we must do, that though steam blockade can be very much closer and more stringent than sailing blockade ever was, we cannot expect it to be absolutely perfect, and remembering that the prizes are far richer than they used to be, it is not reasonable to assume that the 900 steamers in France thrown out of ordinary com- mercial work by the war would not be largely employed for raiding purposes. There are 620,000 or 630,000 British ships entering or leaving our home ports every year — 1,800 or 1,900 a day — and they cluster like bees off all our great estuaries, the Thames, the Humber, the Tyne, the Clyde, the Mersey, the Severn. A great rich belt of trade eternally girdles our shores, of which the richness may be measured when I tell you that I have had the ships counted from Beachy Head for a period, and that there are always thirty-five ships in sight there, and there is a ship passing every five minutes. If the "despicable" privateer, eighty years ago, could make such havoc when shipping was thin and winds un- certain, what grounds have we for supposing that the equally " despicable " raider will not in a future war do much more mischief in the much larger and richer field now open to him ? Plainly, none. That sort of attack on our commerce is as certain as any operation of war that can be reasonably predicted. The operations of the raider will be limited by the question of coal supply, and what he does must be done in two or three days. Should no steps be taken to prevent 158 ESSAYS ON NAVAL DEFENCE. him, the raider who is lucky enough to break the blockade will assuredly make for points where the shipping is thickest, and where most w;ork can be done in the shortest time. No doubt he will approach in the guise of the innocent British or neutral merchant steamer. His object will be to run alongside two or three ships and secure them by means of prize crews for capture, or dynamite for destruotionj before his real character has been discovered ; and speed in the transaction will be all-important to him. It seems as if, unless there are armed ships ' on the spot wherever shipping is thickest, a single raider in the short time at his disposal might do enormous damage. Our noble Ohairmanl has headed a movement to utilise the great Volunteer forces which are so ready to hand in this country, and to commit to them the charge of defend- ing our home waters against the raiders of the class specified — the only class which can in any properly organised system of naval defence approach our shores. The idea has been to arm local steamers so as to make them the equals of the raiders they are likely to meet, to man them with Volunteer crews, and to station them at all points where shipping is likely to be threatened by the sudden rush of the raider. The Admiralty has given its concurrence and approval of the plan, and we look to see it extend, not only on the ground given, but also from the absolute necessity which is before us of enabling the citizens of a naval nation to throw themselves into the defence of the waters surrounding these islands which certainly ought to be preliminary at least to the defence of the land. In this paper I have not estimated whether our present fleet is, either in quantity or quality, sufficient to carry out ^ Earl Cowper. THE NAVAL DEFENCES OF THE UNITED KINGDOM. 159 Lord St. Vincent's plan of defence. It has seemed to me that such a discussion would properly follow the acceptance of his system. But I am bound to say, in order to avoid misapprehension, that we seem to be little prepared for it, and that in war even with France alone, we should have to fall back on Lord Howe's system, which I understand to mean practically the abandonment of our commerce, though our shores would be perfectly secure.

THE RELATIONS BETWEEN LOCAL FOUTiriCATIONS AND A MOVING NAVT.l In a lecture delivered in this theatre on the 18th January, Captain Stone of the Royal Artillery made a sort of excursus iato the domain of naval action and policy, when discussing the employment of "Quick-firing Guns for Fortress Defence." In laying down certain propositions with regard to the re- spective functions of a moving Navy and fixed fortifications, and in declaring himself a " looker on " at the game of a combined effort, or of a rival effort, between these two elements of defence, I thought Captain Stone was doing good service in challenging, ab initio, those who supported or denied his positions, to come out, and state their case. As I listened to the lecture and to the discussion, I came to the conclusion that probably neither lecturer nor audience had exerted the critical faculty in sufficient strength to notice how far an acceptance of the propositions put forward might lead us if we followed them up ; and at the same time, I felt that under a paper with a secondary title, it would hardly be convenient to raise a full debate on pri- mary issues. But those who listened with me, must, I think, agree that primary issues of great moment were raised in the ' Written in 1889. LOCAL FORTIFICATIONS AND A MOVING NAVY. 161 paper, and pronounced upon with decision in a way which does not wholly accord with some presumably careful ex- aminations that have been recently made. The paper on the " Naval Defences of the United King- dom," which I had the honour to read here last year, did undoubtedly tend to raise the value of moving naval defence and to depress that of locally fixed defence. Cap- tain Stone's paper, to which, so far, this is a reply, unques- tionably took the opposite view, and practically claimed? that " Naval Defence " was a contradiction in terms ; the rdle of the Navy not being defence at all, but attack. Here, as the lawyers say, " issue is joined " and most conveniently so for discussion. It is seen that a very wide divergence of opinion is not only possible, but is in flourishing exist- ence, on the subject of the relations between fixed fortifica- tions and a moving Navy, and I hardly think we can better employ a couple of hours than by endeavouring to thrash out some of the truth as to these relations. In the Navy I venture to think that we ought to bo a great deal more critical and observant than we are on the subject of our fixed, or localised, defences against naval attack. And though I advert to the matter with the greatest possible diffidence and deference, I sometimes fear that the Army is hurting its efficiency by pressing forward the idea of strong coast works at home and abroad. I sit at the feet of Colonel Maurice so far as I form any notions of military policy, and I fail to see how such views as he expresses stand any chance of being carried out, if we are to greatly shut up the military forces of this country in detached garrisons all over the world. With still greater deference, and very humbly indeed, I venture to say that in our military policy, I seem to detect three incompatible lines being pursued. There is the line JI 162 ESSAYS ON NAVAL DEFENCE. which steadily regards the invasion of these islands, not as a possible conclusion to a series of disasters such as history furnishes us with no examples of, but as an incident of war at least as prominently near us as a great sea-fight. This line, when pursued, demands the raising, main- taining, and training of a vast body of troops on principles such as we find in continental countries, and it will ask for the fortification of London, at least, if not for converting defensible points surrounding London into a series of first class fortresses. It was this policy that dictated the great land-side works which profess to defend the arsenals of Portsmouth and Plymouth. The second line of policy is what I understand to be that of Colonel Maurice, where the Army is to be prepared for embarkation under the convoy of, and disembarkation under cover of, the Fleet, for those sudden military attacks at unprepared points of the enemy's shores, which the rapidity and certainty of transport over a commanded sea, makes easy for this nation. The third line of policy is that sketched by Captain Stone, if 1 rightly apprehend him, namely, the dispersal of the Army all over the world in detached garrisons. The three lines of policy would seem to me to require three separate armies to carry them out in their entirety ; and if I endeavour in this paper to show cause against the last of them, where my naval knowledge, and some study of the question may justify me in holding an opinion, I trust I shall not have intruded too far on military ground in men- tioning the first and second. Nothing could be more satisfactorily clear than Captain Stone's expression of view ; and it is always an advantage to the solution of a controverted question to start with a clear enunciation. LOCAL FORTIFICATIONS AND A MOVING NAVY. 163 " My premiss is," says Captain Stone, " that the posses- sion of naval arsenals, dockyards, and coaling stations must practically decide the question of naval supremacy. That such supremacy isabsolutely essential to our existence as a nation; and that the way to secure it is to fortify and arm our own arsenals, dockyards, and coaling stations in such a fashion as to enable them to resist an enemy's attacks, and at the same time to give a free hand to the Navy to attack those of the enemy with such force as may be available, after providing for the patrolling of our principal trade routes, and the formation of such fleets as may be con- sidered necessary to enable us to force on a naval engage- ment when opportunity offers, with forces adequate to inflict a crushing and decisive blow on the enemy.'' The main view here is that the fortiflcation of posts described will enable a given naval force to do things which it could not do were the posts left locally undefended; and a principle underlies it, declaring that naval force is not properly a defensive, but an offensive force ; while military force, concentrated in localities, is truly the defence of, a maritimo, empire. Sir John Adye, in a letter to the " Times " last year, on which I had the temerity to offer some criticism, did not quite take up the general relations between fortified har- bours and moving fleets, but he spoke of " adequate land defences of harbours " being the " complement " of their naval defences. He presupposed, however, at least so far as our home porta are concerned, a loss of the command of the sea, and an enemy free to attack without fear of inter- ruption from the sea. He said : " As regards land defences, I would point out, in the first place, that should this country be threatened with attack by an expedition across the sea, it is very important that our enemies should be denied M 2 164 ESSAYS ON NAVAL DEFENCE. access to our harbours, and should be compelled, at all events, to make their attempt on the open coast. Their chances of success will be much minimised if they have no secure base of operations." (Sir Edward Hamley used, I think, the same argument in the same way.) " That is one point, but there are others. When hostili- ties arise, our vessels, whether of war or of commerce, will often require to return to port to discharge their cargoes or to obtain supplies of coals, munitions, food, &c. They may also have to take refuge in consequence of damages in action, or by stress of weather ; and when necessity thus compels them to seek a harbour of retreat, it is essential that they should be able to refit in security, and be free from molestation." At this point I must discriminate a little. We can see that the same view precisely does not animate the minds of two military men, one of whom brings to it the weight of experience in a long and very distinguished career ; while the other must treat it by the light of a less experienced intelligence which even a short career has shown to be of a high class. Present to Sir John Adye's mind is a picture of more or less failure of our naval forces, more or less incapacity to protect territory by purely naval means, or more or less defeat at sea. If fortifications are necessary to " deny the enemy access to our harbours,'' if they are required to enable " vessels whether of war or of commerce, . . . to return to port to discharge their cargoes or to obtain supplies of coals, munitions, food, &o.," this must either be because of the inability of a moving Navy to do it ; or because the military defence by fortifications can do it equally well at a much more economical rate. If fortifi- cations are necessary to enable ships to take refuge under LOCAL FORTIFICATIONS AND A MOVING NAVY. 165 them after damages in action, or by stress of weather, the conception must be'that the enemy has beaten them so much as to be able to follow them up, and to be only prevented from annihilating them, or hindering the restoration of their efficiency, by the fortifications within which they have secured themselves. These several conditions do not appear to be at first pre- sent to Captain Stone's mind. In his view the Navy is in full competence and efficiency. There is no question of its failure in any way. But fortified arsenals and ports of supply are a convenient method of releasing naval force which must otherwise be detained locally for the defence of the ports. It is, in Captain Stone's conception, a fundamental postulate of naval warfare, that when an Admiral leaves the arsenal from which his fleet emerges complete, for the purpose of an attack on one of those of the enemy, he must be assured that his own port is thoroughly well locally defended. And the inference is that if it is not thoroughly well locally de- fended, he cannot attack, for he must remain there to de- fend it himself. Undoubtedly both sets of opinion as to the relations be- tween fortified ports and a moving Navy are largely held ; and the holding of them is not confined to the military service. Being largely held, it almost inevitably follows that there must be, somewhere, a certain amount of truth about them. But, on the other hand, I think it may be safely said that none of them would arise naturally out of the study of naval history. More than that, I think they do not arise directly from the reason of the thing, when we come to face it. I rather think such thoughts are not the cause, but the effect, of fortified ports. Having observed fortified ports all over the world, we have imitated, without much 166 ESSAYS ON NAVAL DEFENCE. close examination, that which we have seen, and ap- plied it to our own ports ; having done so, we search for and produce such raisons d'itre as we are able to do, to account for their presence ; and then we call in those raisons d'Stre as an argument for the extension of the system. The impoftanoe of the question I raise, and the difficulty in dealing with it, spring from the fact that, primd facie, no one denies the value, if not the necessity, of a certain amount of local defence for the ports of a maritime empire. But then no one knows where to stop. I can never forget that while many military and perhaps more naval men think that the gigantic defensive works of Portsmouth and Plymouth have been over-done. Colonel Schaw demanded, in this theatre, in December, 1886, that £833,000 more should be spent upon those at Plymouth before they could be in any way considered complete. T need hardly advert to the Report of Mr. Stanhope's Committee lest year. It will be fresh in all our minds that the demand for local works, both new and additional to old ones, was very large indeed, and that the actual millions taken up by loan for this service did but partly represent the view which was put forward as to the necessities of the case. Who is to fix the degree of fortification at which the local defence of a port should stop ? If an authority de- clares the fortification of any port is insufficient, what argu- ments can we use to prove that it is sufficient ? As a naval, friend of mine, for whose opinion I reasonably have a high respect, has said : " There is nothing between a light bat- ■ tery and a first class fortress." I, myself, have generally felt that the arguments which will call for any fortification of a port against attack from the sea will equally apply to ask for its defence against all the navies of the world. I cannot tell, myself, what the measure of the defence ought LOCAL FORTIFICATIONS AND A MOVING NAVY. 167 to be ; and the only certain check I know, upon expen- diture on local defences when once we begin, is our general way of looking at it. It does not appear to me to be of any use saying that defence by the fortification of ports and defence by a moving Navy must go hand in hand. Were they both under the same administrative control — which could only be naval control, with any reason — they might be dealt with side by side, though I do not think that even then they could be said to go " hand in hand." But as we stand, they are rivals for the open palm of the Chancellor of the Exchequer, and nothing is to be gained from not recalling the fact and stating it plainly. The reason of the thing, and the history of the thing, come to my mind with a plain conviction that fortification of ports is but an ineflScient substitute for their naval defence, and that as we propose a naval increase we should logically propose a fortification decrease. But the reverse is our policy, and the moment the naval experts urge a naval increase, the military experts, and sometimes the naval ones too, are equally, if not more, urgent for local port defences. I should like to say here, that for the purposes of my argument, and to keep it clear of side issues, I wish to roll the fortification which is got out of land batteries, coast defence vessels, and submarine mines, all into one. When I speak of fortified ports, I mean ports that are locally protected against attack, whatever the means used may be. But I do not include such local and movable defences — such light vessels — as may be prepared not to defend the port itself from attack, but to warn ofi the roving cruiser which might seek either to blockade the place, or to capture or destroy the unarmed ships frequenting it. 168 ESSAYS ON NAVAL DEFENCE. I draw a distinction, in fact, between the defence of the port against attack, and the defence of the communications of the port. As I have said above, I think the best standard we can at present erect as to the share which fortifications should carry away from the till of the Chancellor of the Exchequer, is one dependent on our general way of looking at the whole question ; and I do not know that there are any proper spectacles through which we can see, except the historical spectacles. But let me first follow up the thoughts that have formed themselves in Captain Stone's mind as consequences of the thesis used as a starting point. Looking at the functions of the Navy he tells us that, " upon the declaration of war one of the first duties of our Navy will be to attack the enemy's military ports, dock- yards, and coaling stations, and thus secure heavy odds in our favour from the outset. In order to secure the greatest results, the rdle of our Navy miist be essentialli/ offensive, and it is much to be regretted that an unreason- able dread of bombardment should have been aroused recently by the naval manoeuvres, tending to form an un- educated public opinion in favour of keeping our fleets in home waters in any national emergency. Bombardment is an operation which requires a vast expenditure of amuni- tion and a considerable time to be effective, and the material damage inflicted is by no means proportionate to the cost of the undertaking, or to the risk incurred in carry- ing it out." We have here the development of the initial idea. Our fleets are absent making attacks on the enemy's ports, which must be, by the hypothesis of possible attacks behind the fleets, well known to be empty of the enemy's LOCAL FORTIFICATIONS AND A MOVING NAVY. 169 warships ; these latter being, as a consequence, free to do what seems good to them. But they are withheld from attacking our arsenals because of the strength of their fortifications, and from bombarding where there are none, because of the cost and tedium of the operation. " I will venture," continues the lecturer, " to touch upon one more naval question, and that is the question of blockade. It has been stated that to spend money on land defences, while our Navy is admittedly insufficient in numbers, strength, and speed for the duties it will have to perform, is an altogether mistaken policy; and further, that if our naval strength were increased as it ought to be, there would be little or no necessity for any land defences at all, inasmuch as the enemy's ports could be so efficiently blockaded that our shores, our commerce, our Colonies, and our coaling stations would be as free from hostile enterprises as they are in peace-time. Our recent experi- ences of naval blockade, when the " Warspite," " Severn," and " Iris " escaped from Berehaven, and united at a rendezvous ofE the Hebrides with the "Rodney" from Lough Swilly, would seem to indicate that the game of naval blockade is likely to be a dangerous and unprofitable one for the blookader, and that the blockading squadron might employ its superior strength to better purpose, and more in consonance with the fighting traditions of the British Navy, by attacking and seizing the enemy's ports !ind coaling stations, and thus forcing on a decisive naval engagement.'' " It will, I trust, be granted that the Navy has its own sphere of action quite apart from the defence of ports and coaling stations, and that this duty must rest principally with the land forces." The " Times " lately remarked that a good deal of the 170 ESSAYS ON NAVAL DEFKNCE. apparent difEerences on defence questions proceeded from want of clear definitions. In these passages there are two words, " offensive '' and " blockade,'' which are ambiguons, and are differently understood. It has come about that a naval meaning has enveloped the word " offensive." It is now common to hear naval officers speak of " ofEensive defence," but they do not thereby mean " attack." They mean advanced defence, and I notice the word applied both to the functions of a squadron watching an enemy in his own port, and " defending '' the sea behind it, by making sure that if he comes out he will be followed and fought ; and to the f auctions of local defence vessels, which operate in waters adjacent to a port and are ready to attack an enemy beyond the reach of the batteries. The word " blockade " I endeavoured to show in my paper on the subject, covered three distinct meanings, namely, "sealing up," "masking," and " observing," and possibly, if Captain Stone has founded his opinions as to the results of the experiments of last year, on what naval officers have said about blockade, he may have failed to fully apprehend their meaning on account of the varying value of the term " blockade." It is well known that Nelson repudiated the term " blockade " when applied to his long watch of Villeneuve in Toulon, and, whatever difEerences there may be amongst naval officers as to the capacity of a blockading squadron to seal another up in its port, there is no rift in the general conviction that the enemy must be watched wherever he is, and followed up, for that the disruption of the Empire is certain if force enough, and of the right kind, be not provided for this purpose. Probably all that naval Officers are certain about with regard to the escape of the ships named from Bantry and LOCAL FORTIFICATIONS AND A MOVING NAVY. 171 Lough Swilly is, that the blockadors had neither force enough nor of the right kind for the work they had in hand. Judgment is perhaps suspended on the point whether any force would be competent to seal up a determined and enter- prising enemy. Captain Stone having, as we see, laid down the functions of fortifications as freeing the Navy, incidentally takes up Sir John Adye's position, and imagines one of our fleets being driven into the shelter of a fortified Plymouth by a superior force of the enemy, " there to refit, coal, and await reinforcements." That means, of course, the loss of the command of the Channel ; and thus having gradually advanced on the original thought of a sea left open to the enemy, while our Navy makes an attack on his land, he passes imperceptibly to the contemplation of our absolute loss of command at sea as something to be looked for in ordinary course, and as something presumably recoverable by military means developed in fortification. "The case of Sebastopol," he says, "is even more instruc- tive, afEording as it does an actual parallel to cases with which we may ourselves have to deal in the event of an invasion of our territory." Here, we must observe, that never, in any war which might have partaken of the naval character, was there such a collapse as the naval force of Russia exhibited. . Never in any naval war was there such complete and absolute command of the sea as England then enjoyed. We see, then, how imperceptibly by laying down a certain founda- tion and building on it, we come to the calm preparation for a state of things impossible before the entire destruc- tion and conquest of what we call the British Empire. Yet I admit that Captain Stone is consequent in his illustrations. It has long seemed to me that if we start with supposing 172 ESSAYS ON NAVAL DEFENCE. to use Sir John Ayde's forcible and difEerentiating words, that fixed fortifications are a necessary " complement " of naval force, we mast be prepared to adm.it that total loss of command of the sea is to be regarded as but an incident of naval war. The conception which Captain Stone has of the Navy carrying the war to the enemy's coast, while leaving an apparently open sea behind it, has so much truth in it that it may be said to be as old as naval war itself. But two corrections appear to be necessary before we can say that it is wholly true. I cannot stop to give instances, but the rule certainly is that a Navy cannot alone make attacks on the enemy's strongholds. Perhaps, if we take out of the list of attacks the bombardments of Algiers, Acre, and Sweaborg, we shall leave nothing behind but such attacks as have been made by the Army under cover of the Navy. I am sure, when I mention it, that the fact will start up in every mind as a familiar one, but 1 ought not to leave it without reminding you that the want of troops was the chief thing that paralysed the French Navy as an attacking force in the Franco- German War. The other correction is that the Admirals who 300 years ago recommended the policy of attack, never imagined it required fortified bases behind them. Their view was the opposite. Sir William Monson, Elizabeth's youngster and James I's Admiral, in advocating that policy, wrote, " that whilst the Spaniards were employed at home by our yearly Fleets, they never had an opportunity nor leisure either to make an attempt on us or to divert the wars from themselves ; by which means we were secured from any attempt of theirs." The historical case of this active naval policy stands thus : It cannot be undertaken at all until the command of LOCAL FORTIFICATIONS AND A MOVING NAVY. 173 the sea is secured — that is, until it is certain that neither the base nor the communications with the base can be threatened, and thai the operation cannot be interfered with from the sea. It must always be abandoned if there is the least chance of the loss of this command of the sea. Let me just recall that so well has this always been understood, that the command of the British seas was the mainspring of all our naval wars, until a time came when it was recognised that we opened the war on the basis that we held the seas. There is positively no explanation of what was done at sea in the Dutch wars but this. It is incomprehensible that the whole naval force of each side should have gathered against the other again and again, and simply fought for the mastery, unless something was to follow when it was gained. And what could follow it but the power of attack on territory as well as the control of the water ? Neither the Dutch nor ourselves ever got so far in mastery at .sea as to contemplate attacks on territory, for we cannot look at De Euyter's raid of 1667, which could not be put in force until we had disbanded our Navy, as an attack. It was an insult, under cover of a not very creditable quibble. Fortification conld not be said to have come into any relations with the moving navies in the Dutch wars. Neither side could attack them for fear of interruption by the other. When, later, we fell into war with France, there was at first the same thing over again. In 1690 Lord Torrington had a divided force, and found himself off the Isle of Wight in greatly inferior strength to the French. But he perfectly understood the situation. The mere neighbour- hood of an inferior naval force which was free to attack was an absolute bar to any operations of the enemy against our shores. " A strength," he wrote to the Council, " that 174 ESSAYS ON NAVAL DEFENCE. puts me beside the hopes of success if we should fight, and ^really may not only endanger the losing of the fleet but at least the quiet of our country, too ; for if we are beaten, they being masters of the sea will be at great liberty of doing many things they dare not attempt whilst we observe them, and are in a possibility of joining Vice-Admiral Killigrew and our ships to the westward."! Here we have the whole argument " in little." No conceivable arrangement of fortifications could have strengthened Torrington's hands ; there was no question of fortifications relieving his naval force. The French Fleet was there endeavouring to fight the English for the com- mand of those waters, in order subsequently to make territorial attacks ; Torrington could not accept battle be- cause, if he wore badly beaten, he would cease to operate as the defensive force that he was. The very object the French had in view was to drive him off the sea under territorial shelter, and therefore the provision of such shelter was not a thing to be contemplated by the Admiral. The .one great fear, both in the mind ol the Admiral and of the Council, was that he might have to. retire north to the Gun-fleet, where his observation would be weakened ; and the Council forced on the battle of Beachy Head to avoid it.2 Torrington, however, saw more clearly, and he would not allow the battle to proceed as far as to leave him really beaten. By this action he won the campaign, and the French, failing to get the command of the sea, were obliged to abandon their designs. The narrow straits in which we found ourselves, had, by the next year, given wisdoin to the Council, and Russell, 1 Bntinck's " Naval History," p. 548. ' Mr. Laughton tells me that this was due to a discreditable intrigue ot Bussell's, LOCAL FORTIFICATIONS AND A MOVING NAVY 175 with a large concentrated force in 1692, fought the concen- trated Navy of France at La Hogue exactly on the principles, and with the objects, of our fights with the Dutch. The French were thoroughly beaten, and ever since have com- menced war with us on the understanding that they were to spend most of their time under the shelter of their fortifications leaving the water territory to us. Four times since then has France made preparations for an attempt to wrest this command of the sea from us, and to follow it up by territorial attack. In 1744, 1759, 1779, and 180.5, fleets were fitted out to dispossess ours of their water territory, and armies were held in readiness to invade so soon as the Channel was clear. In 1744 and 1779 the fleets showed in the Channel, but dared not make good their pretensions. In 1759 the intended Channel commanders were smashed up ofE their own coasts by Hawke and Boscawen ; while in 1805 Villeneuve failed of the nerve which was required to face the enormous risk. In no case through all these series of operations can we bring our fortifications into relations with our fleets at all in the home waters. On the other hand, there were always the closest relations between the French fleets and the fortifications under which they sheltered theniselves. Our Admirals never thought about their bases being fortified, being fully persuaded that they were themselves their defence. And the mere fact that the open anchorages of Cawsand Bay, Torbay, St. Helen's and the Downs, were their points d' appui, accounts for the absence of all expressions of doubt as to the support which might be afEorded by the shore. But I suppose the answer may be that these were the ' days of sailing ships, and that steam has altered all the 176 ESSAYS ON NAVAL DEFENCE. conditions. It is right to advance the argument, provided it be followed up, but not otherwise. Experience has taught us certain plain principles of naval war, and a new factor has been introduced. We cannot say that this new factor has voided our experience, though it is proper to say that it mmf have done so, and to examine the possibility. What is it that steam and electricity have done for naval war ? They have everywhere replaced uncertainty and chance, by certainty : they have immensely shortened times, and distances as measured by times. If, in a general way, the balance of power on a water stage of war was liable in the days of sailing ships to dis- turbances through the influence of the chaptei of accidents, it is far less liable to such disturbances since the days of steam. There has been experience enough to confirm the dictum. Perhaps there never was so smooth and un- broken a naval campaign as ours against Eussia. It was steam alone which made it so. It is on clear record that it was steam alone which enabled the Federal States to adopt that " anaconda " policy to which the South ultimately succumbed. It could only be the conviction of the uselessness of all attempts, which caused the Germans to make practically no diversions by sea in the Franco- German War. Certainly in the Chilo-Peruvian War there were cross purposes of the old sort until the " Huascar " was captured. But a naval war between two ships on one side and one ship on the other is hardly of a character to generalise from. And so we have it that the feature of steam naval war is certainty. If it be true, as undoubtedly it is, that combinations for attack can be more suddenly and with less warning put into action; it is also true that the time which can be allowed for the attack, before it is inter-' LOCAL FORTIFICATIONS AND A MOVING NAVY. 177 rupted, is very much limited, and the limit is very much more sharply and certainly drawn. With regard to fortified places exposed to attack from the sea, the general efEeot of steam can only have been to add to their strength, not to demand its increase. No one has yet discovered or invented a fortified port capable of maintaining itself for all time against a sea attack. Every such place as yet has fallen when attacked from the seal unless relieved from the sea, provided the attack has been persevered in. And the point is that steam has made relief from the sea more certain and more speedy than it used to be. Relief which was necessary to preserve Gibraltar used to reach that fortress in a month at the earliest. It would now reach it in three or four days. An enemy, with three weeks before him, might very well proceed to the attack of a place, which he could not dream of if he had only three days before him. SufEren, when he dared the attack on Trincomalee, did so because he thought Hughes was a fortnight distant at Madras. A modern Suffren could not now attack Trincomalee unless a modern Hughes was no nearer than Suez. But let us construct and follow up such a case, as is suggested by Captain Stone's postulates of the relations between the fortified base and the squadron which is attacking the enemy's arsenals. Let us suppose that an Admiral is bombarding Brest with ten battle-ships, and that he is enabled to do it because his base, Plymouth, is securely fortified. I must assume that, in the view put forward, there is an unmasked force of the enemy within striking distance of Plymouth, for if there be not, the ^ Attacked from the sea, that is, as I have said in the earlier part of my paper, by combined naval and military force, the only force capable of making a determined attack. N 178 ESSAYS ON NAVAL DEFENCE. fortifications can play no part. The condition of the Admiral off Brest is that he requires constant supplies of all kinds from his base ; there will be a constant going and coming of store-ships and war-ships, and every now and then an injured ship going home for repair. The Admiral is distinctly told that he has his " own sphere of action quite apart from the defence '' of Plymouth as a port, but in the middle of his bombardment he receives intelligfinoe that five of the enemy's battle-ships — a part of his unmasked force — are lying a mile or two off Penlee Point, just.clear of the Plymouth batteries. What is the Admiral going to do ? Can he go on with his bombard- ment, while all his supplies are liable to be cut off, and his ships, in going and coming, to be destroyed in detail ? It may be perfectly true that these enemies cannot long maintain themselves, though why they should not do just as he himself is doing, it is not so easy to see. But I do not think there can be any disagreement amongst us in deciding that our Admiral has no course open to him but to abandon his attack and proceed full speed after the five battle-ships that have been threatening his communica- tions. Yet, if this be so, the whole theory of fortifications at the base " relieving '' the naval force falls to the ground. Plymouth, separated from him, is as bad — to him — as Plymouth destroyed ; and the threat of separation governs his conduct in precisely the same way as the threat of destruction does. As far as I can carry my reasoning powers this hypothetical case is conclusive, and it governs the circumstances of every open port which is fortified. There remains no ground for saying that the fortification of a port which it is necessary to keep open will in the slightest degree relieve .the naval force. LOCAL FORTIFICATIONS AND A MOVING NAVY. 179 Bat suppose Plymoath in this case to have no fortifica- tions at all. What then ? I imagine it will be said that five battle-ships would steam up and destroy the dock- yard, and so do a permanent injury instead of a temporary one. If so, the Brest fl.eet must still come home just as before, and, therefore, there is no effect on the fallacy that the fortifications of the base, or open port, will relieve the naval force. But an inner question arises as to whether the five battle-ships would steam up and damage, even if it were entirely unfortified ? Naval history, as far as it goes, is conclusive with a negative answer. It tells us that the neighbourhood of a possibly interfering naval force is a complete bar to any attack on the shore whatever. Though time presses me, I cannot forbear to give some illustrations. One of our earliest entries into the Medi- terranean in force was made by Russell in 1694. The French fleet was then parrying on operations against Barcelona, but the arrival of our fleet at Oarthagena was sufficient to cause their entire abandonment, and to force the French to retreat to Toulon. Next year Russell, being engaged in an attack on Palamos, 150 miles from Toulon, abandoned it on news reaching him that the French were in a condition to put to sea from that port. This instance is the more interest- ing since, at the very same time, we, being unthreatened by sea in the Channel were at our leisure bombarding, and in great part destroying, St. Malo, Granville, Dunkirk, and Calais. The attempts to re-capture Gibraltar, made by the French in 1704-5, were always frustrated by the appear- ance of Sir John Leake's squadron from Lisbon. Twice was the attack proceeded with, and twice was it abandoned in fear of Leake's ships. N 2 180 ESSAYS ON NAVAL DEFENCE. Thurot's elaborately prepared attack on the east coast of England in 1759 was prevented by the presence of the squadrons of Commodore Boys and Sir Percy Brett. In 1782 SufEren was proceeding to the attack on Nega- patam with land forces. The intelligence that Sir E. Hughes was in the vicinity caused the immediate dis- embarkation of the troops, and abandonment of the design. Whenever it has been determined to proceed with a territorial attack capable of interruption from the sea, it has been necessary, either to mask the possibly interrupt- ing force, or to employ a fleet of observation as a guard against interference. Thus, Sir George Rooke could not have attacked Gibraltar had he not been able to do it with no more than twenty-two ships, while thirty-seven formed a guard ready to engage the French if they had appeared. When De Grasse captured the island of Tobago in 1781, almost under the guns of Rodney at Barbados, he took care not only to employ surprise in the operation, but to have such a covering fleet as made it impossible for Rodney to think of attacking him. When Suffren captured Trincomalee in 1782, he be- lieved he was taking pains to assure himself that Sir Edward Hughes' fleet was at least a fortnight distant ; but yet the thing was done under guard of a fleet which was capable of fighting a drawn battle with Hughes on the eighth day, the place having fallen on the sixth. When it was determined to attack St. Malo and other places on the French coast, in 1745, an essential part of the plan was the masking of the French war-ships in Brest by Rear- Admiral Anson. In 1761, when Keppel attacked and captured Belleisle, LOCAL FORTIFICATIONS AND A MOVING NAVY. 181 it was a necessary element of success that a strong squad- ron should mask the ships in Brest. All these lessons are found in full force as late as the Franco-German War. Then Bouet-Willaumez was in com- mand of a vastly superior fleet, yet would not risk the simple bombardment of an ill-defended coast town, Kolberg, because of possible interruption at the hands of the inferior German squadron, which was 700 miles dis- tant. But to make the reasoning complete, we must not omit to note that two Commanders, and I believe two only, have been found to defy these lessons of experience — the Duke of Medina Sidonia, and Admiral Persano ; the former defied the tlireat of the naval force at Plymouth, the latter of that at Pola. Whether a third Commander will be found to follow in their footsteps is probably questionable. The fact that a fortified Brest and a fortified Toulon has always preserved the French fleets from our assaults is, of course, conclusive as an argument that the naval Power which has not the command of the sea, may, by means of fortifications, preserve a fleet for a time at any rate. It is a matter of fair reasoning to say that if your fleet is the most precious thing you have, even when it remains in a state of forced inaction, you can preserve it in your harbours by means of local defences of such strength as will send the enemy anywhere and everywhere before he will be driven to make his attack on the fortified ports. But we cannot forget, at the same time, that a householder can make the fastenings of his hall door so strong that the very last thing the burglar will think of will be the forcing of. them. But I conceive we have established the fact that before a country can employ such fortifications at all, she must have surrendered the command of the sea, 182 ESSAYS ON NAVAL DEFENCE. and if such, command has been necessary to her empire, she must have abandoned empire. Let us for one moment push this thought home as in the applied case of one of our fleets being beaten under the shelter of the Plymouth works. When we think of such a thing, we must, in the face of what has been said, suppose that we hare no relieving fleet at hand. Were there such a fleet, it is manifest that the victorious enemy would court destruction in pursuing our beaten fleet up an intricate harbour, where it was liable to be caught by the relieving fleet. We do not, in fact, in our thoughts admit the existence of a relieving fleet. There could not be such a thing at Portsmouth, for instance. Yet the theory must be that in some way this command of the sea, which has been lost, can be regained, and be regained out of Plymouth alone. How is the fleet which has been defeated into Ply- mouth to come victorious out of it ? And supposing such a thing possible, how long will it be before this happens, and what will the enemy be doing meantime ? It is a clear historical fact that France never tried to get the command of the Channel unless she had an army ready to make use of that command. Will she not always follow that plan, nay, is this not what we are chiefly told to fear ? Would it, in any of those cases I have men- tioned, have mattered the least to Prance whether she had driven our fleets under fortifications, or only up the har- bour ? Would not either process have equally served her turn ? I think that when we thus press £bings home, we begin to see that there is great reason to doubt the wisdom of spending largely on gigantic defensive works with the idea that our beaten fleets may recover themselves behind them. I have been considering the case of great naval bases LOCAL FORTIFICATIONS AND A MOVING NAVY. 183 with which it is of imperial necessity that communications should be open, and where severed communications mean loss of command of the sea, and break up of Empire as a certain consequenco. These great ports do not really differ in character so far as I can see, though they difEer in degree, from what are generally called coaling stations, that fe, ports of supply. If we think of Gibraltar, Malta, Aden, Colombo, Singapore, and Hong Kong, we usually , regard them as ports of supply for our Eastern traders as well as for our war-ships engaged in protecting them, and without going at all beyond that thought — perhaps only in- cluding the latter branch of it — we have spent, and are spending enormous sums on the local defences of each place. What is it exactly that we are aiming at ? What are the conditions we assume to be present when these works shall be brought into play ? There seem to me to be but three possible sets of them. First, that the existence of the local defences shall act as such a scare to the enemy that they will never approach. Second, that we have lost the command of the sea, but could regain it if only these places are preserved to us. Third, that though the places should not fall, enterprising raiders might suddenly cut in and destroy the coal and other stores which would be, without local defences, exposed to assaults lasting too short a time to be interfered with unless every defence were on the spot. Two of these places, Malta and -Gibraltar, have had a history, and a third place of like strategical character — Minorca — brings in a history necessary to complete the other two. The history of Malta is quite simple. France with a local command of the sea, which could not have existed in. steam warfare, took possession of the place. The French I 184 ESSAYS ON NAVAL DEFENCE. losing the command of the sea, simply in consequence of the presence of a superior fleet, held on to Malta from September, 1798, for two years till September, 1800. It has never been threatened since, but we have never since lost the command of the Mediterranean sea. The whole of our operations during our command of the Mediterranean were (unless we except the small use made of Minorca in 1799) conducted with undefended bases, generally open road- steads. Minorca, by the joint efEorts of the Army and the Fleet, fell into our hands in 1708. It was then a duly for- tified place, but we were in command of the sea. In re- mained in our possession till 1756. Then, as will be remembered, Minorca fell as a consequence of Byng's failure to wrest the command of the sea from the French. Coming back into our hands in 1763, we held it till 1782. From the outbreak of the war with France, in 1778, we had made no attempt to keep the command of the Mediter- ranean Sea. Our commerce there was of small account, and such as it was, it must have been abandoned, as the full force we maintained, was but one 60-, one 50-gun ship, 2 frigates, and a sloop. When Spain declared war in 1779 there was nothing to prevent her bending all her energies to the recapture of Gibraltar and Minorca. Neither was there any relief for Minorca from the sea, and it accordingly fell in February, 1782. But again, we had restored com- mand of the sea in 1798, and Minorca became ours once more, as soon as we desired it, without the loss of a man. Here then are two places, Malta and Minorca, both ' for their time very strong places, yet both following simply the possession of the sea. That the fortifications prolonged the sieges may be admitted, but what must also be allowed is, that these places could only be attacked by the Power LOCAL FORTIFICATIONS AND A MOVING NAVY. 185 which held the command of the sea. In these instances then, it seems we must narrow the functions of fortifica- tions down to preseifving the places for a limited time after the sea, and with it the communications, have been aban- doned. We" cannot contemplate bringing the fortifications of Malta into actual use until we have abandoned the Mediterranean and our Eastern commercial route. I venture to think that when great sums go into the works of Malta there is not a distinct recognition that we are preparing to abandon the Mediterranean route to India and the whole of that line of commerce. The case of Gibraltar is full of instruction. I have already mentioned how it fell into our hands, and how it was kept in our hands in its earlier days, not by the strength of its fortifications, but by the relieving fleet of Sir John Leake, who had his base at Lisbon. Spain being in 1780, as we have noted, in command of the sea, made a most determined set at Gibraltar as well as at Minorca. I believe we generally consider that the former place was preserved to us by its strength. We are not always reminded that what really preserved it was the employment of the whole available naval power of England in 1780, 1781, and 1782. In each of these years it would have fallen, just as Minorca fell in the last of them, had not immense fleets been dispatched to cover its re-storing and re-victualling. In January, 1780, Sir George Rodney, with fifteen sail of the line, after defeating the Spanish fleet, opened communications with Gibraltar and relieved it. In March, 1781, Admiral Darby sailed for the relief of Gibraltar with no less than twenty-nine sail of the line, near 200 victuallers, store-ships, and others. And connected 'nith this fleet there is the remarkable fact that just about the time that it would have been ofE Brest, 186 ESSAYS ON NAVAL DEFENCE. De Grasse was sailing with a great fleet and army for operations against us in the West Indies. Such a coinci- dence ought to make us extremely cautious in acting on the supposition that fortifications will relieve our fleets. Those of Gibraltar certainly did not in this case. In Sep- tember, 1782, Lord Howe sailed with thirty-four sail of the line and an immense convoy. The fleet, engaging in a partial action with the Spanish fleet, for the third time prevented Gibraltar from falling into Spanish hands. We may say, indeed we must say, that but for her fortiflcations, Gibraltar would not now be in our possession. But we must also say that had it been necessary for us to keep up unbroken communications with Gibraltar, as it now would be on account of our trade, the fortifications would never have been called into action ; and had we not for three successive years put out our naval strength to relieve it, the fortifications themselves would not have preserved it to us. Again, we seem to be met by the conviction that fortifi- cations can only represent delay. That they are not of themselves of use to a moving Navy, as fortresses on land may strengthen the position of a moving army by cover- ing its flanks, &c., but that wherever communications are given up, they may enable a place to hold out until relieved. Some thoughts of a highly paradoxical character will intrude themselves at this point. Gibraltar was a very strong place with a very weak garrison when it fell into the hands of Sir George Rooke. Because it was a strong place it was ever after necessary to put within it a strong garrisoUi At a time when it was not of the slightest use to us, it exhausted our naval strength in its defence ; had it not been a strong place with a great garrison we should LOCAL FORTIFICATIONS AND A MOVING NAVY. 187 simply have evacuated it when it was necessary to abandon the Mediterranean, just as in 1797 we evacuated the island of Elba. We should have done it in the consciousness that it would fall back into our hands as soon as we re- occupied that sea, and the place became of restored value to us. Considering it to be merely a dep6t for the supply of our war-ships, we must note it as an exhausted dep&t — the shell of a depot — unless we kept up communication with it. That is to say, it could not in any way have assisted us to regain the command of the sea, for we must have got the command of the sea before we could restore its value as a depot. There is, therefore, a certain danger in making a depot which is necessary to us, too strong locally, as, should it fall — as it must if we abandon the command of the surrounding sea long enough — the fact of its strength may retard and hinder the restoration of our oom- mandof the sea. Had the Spaniards not originally made Gibraltar strong, we could not have held it when we left that sea, and Spain need not have exhausted herself in fruitless efforts to get it back again as a necessary part of her restored command in those waters. I am only using Gibraltar as an illustration, not sug- gesting more with regard to that particular fortress than to say that if our communications with it are necessary, the place must be held by means of these communications and not by its isolated strength, and that the illustration governs all naval depots — that is, all naval bases which are not producers of naval strength, but only renewerg of that strength^depots which in these days of steam are chiefly regarded as stores of locomotive force. ., Gibraltar may not be of great importance as a naval dep6t. In the wars of the past it certainly only shared 188 ESSAYS ON NAVAL DEFENCE. the importance which, from the naval point of view, was held by the wholly indefensible bases of Tetuan, Lagos Bay, and Palmas Bay. But were Gibraltar once more in the hands of Spain, the necessities of our case would probably determine that if we were to retain our Mediter- ranean route to India and the East, we should repossess ourselves of it. It may not be of advantage to the Power whose life depends on a free Eastern highway, but it might be impossible to preserve that highway free if the Power determined to bar it were in possession of Gibraltar. Reverting now to the three alternative functions which might be assigned to the fortification of Malta, Gibraltar, and other depdts on a line of communication, we do not seem justified by history in assuming that any fortification will act as a scare to prevent the Power controlling the sea from making his attack. Secondly, we are hardly justified in supposing that if we lost the command of the Eastern routes, these dep6ts being still held by us would materially assist us in regaining it, and this for the simple reason that they would be exhausted depots when we restored communication with them, though, after we had regained command, they would be of the same use to us which they are at present. There remains the third function of fortification, namely, the protection of the stores — the protection of the dep6t proper, and not the shell of it — from the sudden surprise and destruction which might be effected in a short time by a small force. I think that the original claim for the local defence of our coaling stations did not go further than this. I think that if the writings of the earliest advocates of this mea- sure are studied, it will be seen that the last thing they Jiad in their minds was that coaling stations should, or tOCAL FORTIFICATIONS AND A MOVING NAVY. 189 could, stand alone. Indeed, I might almost go as far as to say that, in one prominent case, the conception now held by the general body is exactly the reverse of that put for- ward more than twenty years ago, and still held by him.l The idea of prepiration for several communications with coaling stations, which has dominated our actual policy with regard to them, was totally absent then. The defence sug- gested was a local sea defence which would prevent com- munications being out by anything short of a considerable force, for it was plainly felt that a dep6t must cease to be a dep&t, and must lose the whole of its value, if the stream of replenishment ceased to flow into it. Think of Singapore for a moment, simply as a naval base. Oar squadron comes in, exhausts the coal supply, and quits. The enemy closes round, seizes the colliers which would have replenished the exhausted stores, fills up his own bunkers from them, and either destroys the rest or dis- patches it to some convenient hiding-place. Our own squadron comes back, drives off the enemy, and finds an empty coal dep&t. So far as our war-ships are concerned, what difEerence does it make whether Singapore has alto- gether fallen or whether only the coal store is empty ? Our squadron there is powerless, while the enemy is left in possession of the sea. The fortifications have abso- lutely failed to hold any relations with the moving Navy. They have not guarded its stores, and they cannot in any way assist it to recover the command of the sea. If, on the other hand, a coal store is very much exposed, the strongest works may be passed by, and an enterprising enemy on a dark night, with good store of dynamite and combustibles, but with very little force, might in an hour or so destroy all the value which the works had been erected to guard. ' Sir John Colomb. 190 ESSiYS ON NAVAL DEFENCE. I think what took place with regard to Port Hamilton gives us a most usefal measure of the real naval thought with regwd to the fixed defences of a purely naval depftt. Superficially we should read it that the Navy rejected Port Hamilton as a depdt unless it had been heavily fortified and garrisoned, but would have been glad to hold it other- wise. And, still, superficially, it would appear that the sole objection to the unfortified dep&t would have been the necessity of detaching ships, really required elsewhere, for its local guard. But the moment we go below the surface we find the governing thought of a different character. Port Hamilton, if valuable as a naval basis at all, would have been chiefly so for operations against the Russian Siberian ports, such as Vladivostock, in the event of war. But the naval instincts, resting on all the broad facts of naval history, declared that such operations required a preliminary com- mand of the sea, also, that if such command existed, unde- fended naval bases would be established as close as possible to the scene of action, and Port Hamilton would, in conse- quence, fail to be of any value. The general conclusion arising seems to be that no moving Navy has ever really laid a stress upon fortified bases. When it is in command of the sea it will always seize and hold convenient bases, but it will rarely, if ever, of itself, spend much on the local defence of the bases. Their defence is involved in the command of the sea. A moving Navy must either be in command of the sea, or fighting for it. It holds its command by the same tenure as an army does, and as two armies cannot command the same territory, so neither can two fleets. If in a given territory, the army of one belligerent cannot attack the fortress of the other while the army of the other is LOCAL FORTIFICATIONS AND A MOVING NAVY. 191 besiegiag another fortress of the first ; so neither can these things happen on the water, Fortifications will shelter beaten, and, therefore, inactive fleets, just as they will shelter beaten armies. Plymouth and Portsmoath might become to our Empire and our fleets, what Metz and Paris were to the French Empire and armies — ^mere receptacles for shutting up force in, while the Empire was being over-run. I do not think that had we, thirty years ago, regarded them from this point of view, we should have spent as much on their local defences as we have done. As regards commercial porta and oat-ports, whether naval bases or not, I take it as plain that every nerve must be strained to secure our communications with them in war, and that it is extremely difficult to defend the ex- penditure of any money on local defence until the commu- nications are absolutely secure. When the communica- tions are secure, the provision of local defence on the supposition that they are not secure, becomes somewhat anomalous. But, on the other hand, outlying property of very great value left very much exposed, is a direct temptation to the attack of it. A Malta dockyard without any defence at all, and capable of being got at and destroyed in a few hours by a couple of dashing cruisers, would be such a tempta- tion; as we might presuppose that our communications would not always be so close as to make it absolutely certain that there might not be half-a-dozen hours when no opposing cruiser of ours would be either in port or in sight. That is one way of looking at it. But when we are dissatisfied with a Malta dockyard, which we admit is a temptation only to a great battle fleet and a heavy land 192 ESSAYS ON NAVAL DEFENCE. force, and when we propose to spend heavily on the works protecting it, rather than on maintaining communication with it, then we are, I think, looking not at the preserva- tion of our Empire, but at its disruption. We must be contemplating the abandonment of our route to India vid the Mediterranean for some indefinite time, and we must be contemplating either the ultimate loss of Malta, or the exertion of the whole of our naval power at intervals for its relief and retention, all at a time when we cannot make the slightest use of it, and are, by the hypothesis, desperately pressed elsewhere. I should observe that all the steam wars confirm the teaching of the sailing wars, respecting fortifications. They have never stood a determined attack from the sea ; they have never given, or restored the command of the sea ; but they have sheltered beaten and inferior fleets, small and large, just as they did in times gone by. But, on the other hand, Bouet-Willaumez carried on his naval war in 1870 from the wholly undefended bases of Langeland and Kioje Bay, even as we had, fifteen years before, carried on ours from the undefended dep6t of Nargen, and as Nelson had, seventy years before, carried it on from the anchorage of Madalena. As I said at the opening of my paper, I did not think we could do more with so difficult a question as this, than suggest ways of looking at it. It will be apparent that my way of looking at it tends to put very great restrictions on the extension of fixed works and of local defences of any kind. I have endeavoured to look at the matter all round, and wherever I formed an opposite view, to endeavour to press it home to its consequences and see what they came to. I have not adverted much to the local defence of purely commercial ports, because I cannot shake myself LOCAL FORTIFICATIONS AND A MOVING NAVY. 193 clear of the conviction that it is the oomnmnications alone of these that are worth defending, and that while the ports are nothing without them, the defence of them includes, inexorably, the defence of the port itself. It is a mere instinct with me which admits light batteries at the entrances of such ports. I cannot, when I face it, reconcile their existence to my reason. 194 CHAPTER V. BLOCKADE : UKDBR EXISTING CONDITIONS OF WARFARE. 1 Had I recollected when I accepted the invitation of the Council to read this paper, that Captain Long had in. 1881 read one here under the title of " The Study of the Tac- tics of Naval Blockade as affected by Modern Weapons," I think I should have asked permission to make some alteration in the present title, for the changes which have taken place in the conditions since then are not such as to suggest any entirely new ground, and I do in fact only hope to approach Captain Long's subject from a possiialy rather different point of view. Indeed the chief change of condition which we may note is perhaps some change of opinion since Captain Long wrote, not of a very solid or reasoned kind, and not founded, so far as I can see, on any definite data. It may be well to point out in the first instance that the blockade of which I have to speak to-day is military blockade — the blockade of war-ships by war-ships. Other- wise it might be easily supposed that it would be proper to touch on the law of blockade and the intricatie question of prize for breach of blockade. If we call the blockade of war-ships military blockade, it would no doubt be convenient » Written in 1887. BLOCKADE. 195 to call the other civil, or commercial blockade, for although it is a military operation it has behind it the sanction of law, whereas military blockade has only the sanction of force behind it. And in considering the subjef.t we shall at once see that whereas we ordinarily speak of military blockade as if it were but one thing, or but of one kind, it is really three things, or three kinds of the same thing. It will be clear to you that this is so when I mention the three words Sealing-up, Masking, and Observing. These words denote three quite- different operations, and yet we know that they have at all times been carried out and spoken of under the same name. I will give you three familiar illustrations which will at once make the distinction clear. Nelson, in March, 1794, speaks of blockade in its first and special sense when he writes, "The blocking up of Corsica he (Lord Hood) left to me : it has been accomplished in the most complete manner ; not a boat got in or a single soldier landed, although 8,000 men were embarked at Nice." Here the object was more to prevent ingress than egress, but it would have been just the same had he claimed that not a boat or a man got out. The ports of Corsica were sealed up. The intention was that nothing floating should either leave or enter them ; that was the ultimate object, and it was attained. When Nelson arrived near Cadiz in October, 1805, with his full force, he was so far from blockading the Franco-Spanish Fleet that he purposely kept his own ships out of view, in order if possible to deceive the enemy into a belief that his numbers were smaller than they actually were ; but he kept close watch on Cadiz by an inshore squadron and repeating ships, so as to have the earliest intelligence of the enemy's movements. If the Franco-Spanish Fleet had not come out this would 2 196 ESSAYS ON NAVAL DEFENCE. have been called blockade. Similar operations bad often been conducted under that name ; but it was evidently not the sort of blockade which the same officer had carried out at Bastia. The object was the opposite of blockade. It was hoped that the enemy would come out, but every pre- caution was taken that if he came out he should be fought. The operation was not blockade ; it was masTcing. So long as the English Fleet was there the Franco-Spanish Fleet was harmless. It could only become mischievous after fighting and beating the English force. Before Nelson arrived off Cadiz the operation was called blockading ; but it was not ; nor was it masking. OoUing- wood took his station off the port with no more than four line-of-battle ships, well knowing that the Franco-Spanish Fleet might any day come out and surround him with thirty-five ships of the line. Oollingwood, therefore, was neither sealing-up nor maslcing ; he was observing. He had no power of keeping the enemy in port, nor of fighting him if he came out; but he had power of watching him, and of reporting his movements. He exercised both. He despatched Blackwood home with news of his arrival ; he remained watching himself ; and had the ships come out he would have hung about them and detached ship after ship until he was left alone to report on their route and probable designs. As there are, therefore, these three distinct operations included under the ordinary term blockade, it requires little reflection to see that we must consider them separately before we can come to any conclusions either on the general subject or on particular applications of it. I shall have to form and to express in this paper opinions as to how far " blockade " can be carried out " under existing conditions of warfare." These opinions are now freely expressed on BLOCKADE. 197 both sides of the question. Great differences exist ; but I am not sure that the disputants have commonly, or even at any time, drawn the distinctions that I have now done ; and it may be found that some of the difEerences have arisen from the fact that opponents have in their minds different things, though they have both been using the word blockade. We may easily, I think, come to two apparently opposite conclusions, and yet not be open to the charge of inconsistency. " Blockade " may be pronounced impossible in modern warfare, and yet " masking " and " observing " — commonly included under blockade — may be held quite possible. A great number of naval ofiBcers hold the opinion that it is worse than useless to go back to naval history for the lessons of modern naval war. I have been for many years past of the contrary opinion — an opinion which grows stronger every day — that it is impossible to form correct views of the present or future of naval warfare unless they are based on a pretty thorough investigation of its history in the past. A Royal Commission appointed in 1859, nominally to consider the " defences of the United Kingdom," but really only to consider the fortification of the Royal Naval Ports, reported in 1860 that, " it would be very unsafe to rely on the experience of former wars in judging of " the question of the power of our fleets to mask those of the enemy. No one certainly ought to " rely " on the experi- ence of former naval wars under sail to guide him in fore- casting the future of those under steam, if to " rely " meant to expect the same thing under very different con- ditions. But this sentence was probably meant to go fur- ther, and to say that past experience was no help to the preparation for the future. It was followed up by the 198 ESSAYS ON NAVAL DEFENCE. wide assertion that because of steam " the efficient blockade of an enemy's ports had become well-nigh impossible." It was the more remarkable that such a thing should be said at that particular date, seeing that six years earlier we had established and maintained by steam vessels a most rigorous and absolute military blockade of all the ports in the Russian Empire for two years. The very next year, too, was to -witness the establish- ment of a blockade of the coast of South America from the Chesapeake to the Rio Grande. And so far from this gigantic operation of war being unsuccessful, it resulted in the destruction of 270 sailing vessels and of 85 steamers, as well as in the capture of 939 sailing vessels and 210 steamers. This steam blockade also was undertaken by a nation totally unprepared for it — a nation which had, when the war broke out, only about twenty-four war steamers, all told in commission, of which the most part were on distant stations. 1 This operation was sealing- up pure and simple. The attempt was to prevent all egress and ingress from and to the enemy's ports — clearly the most difficult form of blockade. The Royal Commissioners were not thinking of this in their modified denial of its possibility. As they were showing that the naval defence of the United Kingdom was not to be depended upon, they must have in- cluded both masking and observing in their use of the word blockade. Blockade in their view had been rendered by steam well-nigh impossible, and so there was the broad chance that the enemy's fleets would evade the masking fleets off their ports and elude the watchfulness of the ob- serving squadrons. ' Soley : " The Blockade and the Cruisers." BLOCKADE. 199 I believe I shall not be far wrong in assuming that another Royal Commission sitting now, might, if it were to decline to examine and draw the lesson from history, be tempted to say that the torpedo-boat had made blockade " well-nigh impossible." It may not be amiss to notice that hardly anyone would agree that steam alone had made sealing-up, masking, or observing more difficult than they had been in the days of sailing ships. It may quite be that the same change of opinion will follow longer acquaint- ance with the torpedo-boat. But my point is that steam, looked at in the light of history, had at least not injured our powers of blockade in any of its three aspects. A contrary opinion could only be arrived at by taking into account all the advantages which steam gave to the enemy for escape from his ports, and neglecting all those which it had given to the blockading force for observing him. Such a blockade as the Federal States set up ofE the Con- federate ports could not have been thought of before the days of steam. It was steam which enabled the ships, to close into the mouth of the port. It was steam which, by mitigating, if not removing, the perils of a lee shore, enabled the Federal ships to anchor as close to the water passage they were guarding, as the range of the enemy's guns planted on shore would allow. There was not generally any real attempt at anything more than observing and masking during the revolutionary war, and only the inshore squadrons of frigates and light ships kept close off the ports containing the enemy's fleets. The dangers of a lee shore necessarily kept the blockading fleet with a good ofiing when the wind was foul for exit from the port ; when it shifted and made a weather shore, it blew the blockading fleet off, and the blockaded fleet out. 200 ESSAYS ON NAVAL DEFENCE. When Hoche and Morard de Galles had brought the pre- parations of the Irish Expedition to a state of completeness in December, 1796, in the harbour of Brest, Colpoys, with (apparently) fifteen sail of the line, was masking them. In the language of Schomberg he was " cruising off Brest '' (Fig. 1). The greater part of the troops were embarked as early as December 1st, and Wolfe Tone, whose journal gives a very fair picture of what was going on inside at Brest, ' embarked on board the " Indomptable " on that day. On the 3rd he could only say it was " pretty certain that the English were in force ofE Ushant to the number of sixteen ships of the line and ten frigates." Colpoys was generally so far off as not to be visible, but the mere idea of his vicinity was sufficient to delay the sailing of the squadron, yet the watch was so loose that Richery with five sail of the line and two frigates got into Brest from Rochefort on the 11th December, and this movement followed on the return to England of Sir R. Curtis' squadron, which had been cruising near Belleisle between those two ports. On the 15th December there had been for more than three weeks a fair wind out of Brest, and then they conld only see from th& lookout at the point, four sail of the enemy. These were Colpoys' frigates ; but he himself had been blown thirty miles to the westward, so that the Erench expedition was able to sail the next night. Colpoys, having thus missed them, returned to Spithead on the 31st. What is the lesson of history here if we choose to read it ? The fair wind out of Brest gave to the French all the advantages which steam could have put at their disposal ; but it took away from the fleet of Colpoys all the advan- tages it gave to the squadron he was watching. If Colpoys had had a steam fleet he would never have been blown PLATE 711. BLOCKADE. 201 thirty miles away. He would have been seen every morning from the Brest signal station, and it is doubtful whether even the idea of the expedition could have matured under such circumstances. As it was, Richery very nearly ran into Oolpoys' jaws on making for Brest. Had the former been able to maintain a position closer in, Richery would never have sailed from Rochefort. I think this historical lesson is complebe. The men are men whether the motive power of the ship be steam or wind. The French Expedition sailing in darkness through the Raz du Sein did everything that steam could have permitted. It was the absence of Colpoys which allowed of the escape. Had Oolpoys been independent of wind, he would not have been absent. Hence steam is shown, by the experience of the past, to have made masking a certainty which it never was before. We might easily misread another lesson, where the same Wolfe Tone tells us the best of the story. On the 8th of July, 1797, he arrived at the Texel and found De Winter's expedition ready to start ; troops were on board, and every- thing complete. The force consisted of fifteen sail of the line, ten frigates and sloops, and twenty-seven transports. The troops embarked came to abont 13,500 men. Lying in the Texel it is apparent that they looked straight out to sea, but though Duncan's fleet was very usually in sight from the Dutch ships, it was not always so. Wolfe Tone on the 14th of Jane counted from the stern windows of the " Vryheid " " ten sail of English ships of war, little and big, who had presented themselves off the month of the Texel." On another occasion De Winter was dependent on the return of a flag of truce for the numbers and force of the enemy (Pig. 2). On the 16 th July, the Dntch officers received their final 202 ESSAYS ON NAVAL DEFENCE. instructions, and only waited for a fair wind to sail, in de- fiance apparently of Dancan's squadron. But the wind was " as foul as the devil." On the 20th the Dutch saw nineteen sail of British ships, but were assured that not more than twelve of them were of the line. De Winter was in fact well aware of every movement of our Navy, and the distribution of our ships. Yet the nearest wind to the N.E. wanted, was N.W. " Damn it to all eternity for me ! " writes Wolfe Tone. On the 20th, Tone had been eighteen days on board, and they " had not had eighteen minutes of fair wind.'' On the 27th and 28th there was a fair wind, but so light that the Dutch could not stir. They could then see Duncan at anchor and counted twenty-two sail. De Winter was in the habit of landing with his glass, and scanning the English fleet from a neighbouring height. Occasionally they were cheered by a whifE of fair wind, but Whenever it came, the tide was foul and they could not move. So things continued till the 21st August, when the ex- pedition, as it stood, was finally abandoned. These conditions were pretty nearly the reverse of those at Brest. The weather was so fine that it enabled Duncan to anchor off the Texel, and to make absolutely sure that the Dutch Fleet was thoroughly masked. He had all the ad- vantages which steam could have given him. The Dutch, on the other hand, had all the disadvantages which dependence on the wind involved. Could De Winter have been supplied with steam for his motive power, how would history have been affected ? Simply it appears that the Battle of Cam- perdown would have been the Battle of the Texel, and would have been fought by the Dutch when they were loaded with troops. The masking by Duncan would have been effective either way. BLOCKADE. 203 Lord Bridport had the reputation of being one of the most persistent and daring of blockaders. An oflScer who had served under him wrote in 1799 that since Lord Brid- port had "held the command of the Channel Fleet, the French have beea blocked up in Brest harbour much closer than they ever were before. No Admiral at any time has kept Ushant so continuously on board as he has done ; not a day passed, when the weather permitted, that Lord Bridport did not stand in ; and when the wind would allow him, he has taken the fleet close in to the Black Rock; his own ship the 'Royal George' has even been within it, which, at the commencement of the war, was rarely done, even by 74's." When it is pointed out that the Black Rock is thirteen miles from the entrance to the Goulet of Brest, some idea can be formed of what was considered close work in 1799, and true explanation is offered of the escapes, and the evasions of our squadrons which sometimes occurred. One of the most remarkable of these took place in this very year 1799, and under the nose of this most dis- tinguished officer. In April, Admiral Bruix had at Brest twenty-five sail of the line, five frigatas, and five smaller vessels ready for sea. On the 25th, Bridport, at the head of sixteen sail of the line, but apparently only one frigate — the " Nymphe " — looked into Brest, and saw eighteen sail of the line at anchor in Bertheaume Bay. Five others were under way, and those at anchor were ready for aa immediate start (Kg. 1). If we had not heard what had just been written, we should have been astonished at Lord Bridport's immediate proceedings, and would have said that he led. up directly to the untoward circumstance which followed. He stood 204 ESSAYS ON NAVAL DEFENCE. away to the W.N.W. at two o'clock in the afternoon, and at four was twelve miles W.S.W. of Ushant, or 30 miles from the French Fleet. Only this one frigate, the " Nymphe " was apparently left to watch ; and it may be that the " Dragon," 74, was somewhat detached towards the " Nymphe '' for the pur- pose of repeating her signals to the Admiral. The wind was fresh at N.E., and the French were there and then getting under way. The accounts are not clear as to whether the " Nymphe " became aware of the fact or not. There was foggy weather either that evening or next niorning, or both, but the result was that at nine o'clock next morning — the 26th — the " Nymphe " jast caught the last ten or eleven of the French ships rounding the Saintes to the southward. The " Nymphe " made all sail to the N.W. to report, but at noon, when she was fifteen miles W.S.W. of Ushant, she had lost the French Fleet, and had not found her own. At one o'clock she saw the " Dragon," who repeated her signal to Lord Bridport, but it was then clearly too late. The French had six or eight hours' start. Lord Bridport, however, made sail for Brest, not apparently being satisfied with the " Nymphe's " information ; then discovering its truth, but not till the morning of the 27th, he fell back to Bantry Bay, being then and subsequently joined by ships which brought his number up to twenty- six. The French never, however, had any idea of Ireland ; they were oS to the Mediterranean, there to efEect certain combinations, and finally to return to Brest, where they lay in overwhelming strength. In this instance, Bridport was either intending to observe or to mask. As forces were on the way to join him, it is possible that he had not the intention of attacking Braix in any case with his sixteen sail. Bat it is clear BLOCKADE. 205 that he nevtjr meant to let the French Fleet out to be neither fought nor watched. Naval officers of the day spoke of the escape of the French as " extraordinary." To us, now, it would seem to have followed naturally on Bridport's proceedings. But as Bridport was not at all the man to let slip a chance, we can only assume that the necessities of sail and wind compelled a course which to our modern notions would seem so mistaken. But then the question for us here is, could this all have happened with steam fleets ? Bruix again, as De Galles before him, had all the advantages which steam could have given him. He had that fair wind which steam represents, and he used it so that he must have been well on his way at breaking daylight on the 25th of April. Was there anything wanting to success beyond the absence of Lord Bridport ? Would Lord Bridport have been absent if he had had a steam fleet ? I tak§ it that no argument can lie on the other side. Even if we allow that Bridport actually feared a battle when the odds were twenty-five to sixteen, and meant to risk the escape of the fleet rather than the chance of an action — still a withdrawal of thirty miles would never have been a necessity for a steam fleet in like disparity. But knowing what Lord Bridport was, and what his brother was, I can hardly believe that the risk of action would have weighed against the risk of the French escaping. I must, therefore, conclude that it was the dependence on wind which made it unsafe for a fleet to spend the night nearer than thirty miles from Bertheaume Bay. But if this be so, what a disclosure it makes of the real inefficiency of the observation, or the mask- ing, of hostile fleets in their own ports during the last great naval war, and what a curious commentary on the generally received axiom that " Steam has bridged the Channel." 206 ESSAYS ON NAVAL DEFENCE. It is useful here to recall Nelson's proceedings in masking Villeneuve at Toulon, as it may remind us that tremendous as the effort was, it failed in the end, and left Villeneuve master of the situation. We have to recollect that this operation difEered in character from those carried on ofE Brest and other Atlantic ports of Trance, inasmuch as the blockade rested on a base 180 miles ofE — the base of the Madalena Islands, at the north point of Sardinia. Nelson joined his fleet ofE Monte Ohristo on July 8th, 1803, and spent sixteen continuous weeks, till the 31st October, watching Toulon. Then the fleet fell back to Madalena for ten days' rest and refit, frigates remaining on watch. From this date to the 19th January, 1805, there was an average interval of thirty-five days ofE Toulon to eight days at Madalena or Palma In the year 1804 the fleet spent 306 days at sea, and yet Toulon was left practically open for two months out of the twelve. With a sailing fleet, retirement to a base 180 miles ofE must have been accepted as giving the escaping enemy three days' start at the very least, and it must have been known that the masking was thus abandoned. It is hardly to be supposed that with a steam fleet resting on the same anchorage, the masking would ever be interrupted for a day. The whole fleet would never abandon the watch. The coaling, provisioning, and re- fitting would have taken place in the ships one by one. Madalena would have become a permanent depot, 'vyhere colliers, store, and ammunition transports, would have assembled in safety. A ship detached from the fleet ofi Toulon in the morning would have been at Madalena for certain next morning, and might very generally have sailed the same night after completion. The work of BLOCKADE. 207 watcliing would have been monotonous, but never hard, even in bad weather. In fine weather, when there was no sign of a move — no lighting of fires — on the part of the enemy's ships in port, communication by boat between the ships of the blockading squadron would naturally be free ; and free also would be communication with traders loaded with all kinds of refreshment for the crews. Pressed by conditions which the invention of the steam- •engine has removed, Nelson was compelled to trust mainly to chance for masking the French. If he had had more frigates he might have had more warning ; but in no case could the retirement of the squadron 180 miles be con- sidered a maintenance of the masking. And thus it turned out; for though by good fortune the " Active '' and "Sea-horse" were able to report to Nelson at 3 p.m. on the 19th of January the sailing of the French on the day before, yet in that act of reporting, all trace of the enemy was lost. They returned quietly to Toulon, but Nelson knew nothing of it for a month, which he had spent in chasing vaguely to the east end of the Mediterranean. Again this arduous, but broken and incomplete, watch was set up ; and again the withdrawal of the whole fleet to Pula Roads in the south of Sardinia left the coast free to Villeneuve. But this time the news of the departure of the French was four or five days' old before it reached Nelson, and it was a fortnight more before the true destination was known. We are easily tempted to ask, when the masking of Villeneuve was of such transcendent importance, how it was that' line-of- battle ships were not detached in assisting the chain of look-out frigates. Nelson had certainly the idea in his mind ; and after the first sailing of the French he told off his two fastest line-of -battle ships, the "Spencer" 208 ESSAYS ON NAVAL DEFENCE. and " Leviathan," to act as a detached sqnadron, and to separate from the order of the fleet. But this was going such a very short way towards doing what we should now, with our present knowledge, and want of knowledge, con- sider a very obvious duty that there must have been very strong reasons on the other side. And then, too, ai'ises the question, why did not Nelson detach one ship at a time from Toulon, to Madalena ? The idea is the first which occurs to our mind when we think of blockade resting on a base at the present day ; it is not possible that it should have escaped our forefathers' notice. I can only suppose that it was the slow and uncertain powers of locomotion possessed by the line-of-battle ships which made the thing impossible. Nelson took his fleet across the Atlantic in chase of Villeneuve at the average rate of three knots only. The difference between the sailing powers of the frigate and the line-of-battle ship were certainly very marked, and it was perhaps a physical impossibility in most cases for a line-of-battle ship to safely watch an enemy's fleet which had frigates at command. So, too, the idea of detaching single ships to refit could not have been put in force on account of the extreme uncer- tainty of the period of absence. Some such strong reason there must have been ; but no such reason applies to blockade under steam. We need not go further into the history of blockade under sail. The teaching is very broad and very plain. It is that a base of some sort was always necessary for a blockading fleet, whether such base was Torbay for Brest, Madalena for Toulon, or Gibraltar and Tetuan for Cadiz. Such base is as necessary, but not more so, with steam ; but then with steam, communication with it has become so rapid, so certain, and so secure cihat none of the BLOCKADK. 209 interruptions enforced by dependence on the wind will tell against the closeness of the watch. Again, the closeness of the watch under steam will be in marked contrast to its looseness under sail. It may be true, and no doubt is so in some cases, that the steam ship requires more frequent communication with the base than the sailing ship, on account of the ex- haustion of her fuel supply. But the modern economies of coal have a tendency the other way, and in any case the consideration does not touch the argument. The experi- ence of the Federals, as well as our own during the Russian War, point to the seizure and maintenance of bases as an essential part of steam blockade. The com- mand of the sea with locomotion independent of wind has — if we are to go by experience — bred an audacity in this kind of thing which far surpasses our seizure of Corsica, Minorca, or Malta. It seems plain that wherever we want the convenience of anchorage and smooth water we shall take it, so long as we can make it safe on the land side. For the blockade of ports near our own shores we shall uBe our own ports, and where those do not sufiBce we shall be found begging, borrowing, or stealing others. It is evident that if the masking or observing of the enemy's fleet in the days of sailing ships was necessarily as loose as we have seen it, the actual sealing up was prac- tically abandoned as hopeless. So far as the enemy's cruisers and privateers went, attempts at sealmg up, if made, were singularly inefEeotive. Lloyd's Lists, quoted in the " Naval Chronicle " for 1807, give a loss of 4,314 British ships to the enemy by capture in the nine years from 1793 to 1800 inclusive, that is four captures in every three days, and showing a freedom for mischief on the part of the enemy of a remarkable character. p 210 ESSAYS ON NAVAL DEFENCE. Captures in the Channel and close off all our coasts appear to have been accepted just as wrecks and collisions now are. The " Naval Chronicle " supplied monthly lists of them without remark, and side by side with the wrecks ; and the prizes, if not met by our cruisers in the open sea, which was often the case, seemed to have no difficulty in getting into French and Dutch ports. The mere conception of such a blockade as the Federals in- stantly prepared to set up on the Confederate coasts, does not seem to have reached our ancestors down to the last, and we can only suppose that the presence of steam prompted the suggestion in the one case, as its absence ex- cluded it in the other. It appears to me that whatever opinions may be ex- pressed now, if we had a naval war we should follow the example of the Federals exactly, and I suppose we ought to succeed as well as they did, provided always we are wise enough to sacrifice everything for the command of the sea. I cannot contemplate in this paper a policy which should assume our failure in this respect, because to assume it is certainly to draw away the money which is necessary to maintain it. The policy of the fox with his hundred defences against the hounds, never commended itself to me so much as that of the melancholy cat, sadly admitting that it had but the one plan of running up a tree if the cry of the huntsman was heard. The issue of the fable should not, I think, be forgotten, by us when we are tempted to sail near the wind in the matter of naval economies. For the lesson of experience and of history is plain. It was the command of the sea alone which gave the Federals their bases, and thus their powers of blockade. The loss of the command of the Mediterranean Sea com- pelled the abandonment of Elba, in 1797, which had, in BLOCKADE. 211 succession to Corsica, become the base for our fleet. In the war between Chili and Peru, the former, though superior at sea, were obliged to abandon the important blockade of Iquique, because of the possible interference of the Peruvian " Huascar." The Federals, determined to take and keep the command of the sea, very soon set up a blockade based on it, which it has been rightly said is without a parallel. " The old traditional idea of a blockade," says Mr. J. R. Soley, in " The Blockade and the Cruisers,'' " maintained by a few large vessels moving up and down before a post at a distance, gave place to the entirely novel practice of anchoring a large number of small and handy steamers in an exposed position close to the bar at the entrance of the blockaded harbours ; and the boldness with which, after the first six months, men kept their vessels close in with the shore, and manfully rode out the gales at their anchors — a thing which sea-going men, as a rule, had regarded as impossible, and which woald have appalled the stoutest captains of former times — showed as clearly as the actual engagements the real stuff of which the Navy was made. " As to the legal efficiency of the blockade after the first six months, there can be no question ; and by the end of the second year its stringency was such that only specially adapted vessels could safely attempt to run it. . . . In the. last year it became as nearly perfect as such an operation can be made. Taking its later development as a type, it is probable that no blockade has ever been main- tained more effectually by any State ; and it is certain that no State ever had such a blockade to maintain." Be it recollected then the author is here speaking of sealing up ; of operations which go very far beyond the masking or observing which would alone be vital to us p 2 212 ESSAYS ON NAVAL DEFENCE. in a state of naval war, and that everything vital to the safety of their own coasts was included in the sort of blockade which the Northern States undertook. That the sealing up was not absolute is sometimes used as an argument that it was inefficient ; and parallels are drawn adverse to our own blockading powers in naval war, which rest on that position. In some minds it would even seem that the escape of vast fleets in the days of sail- ing blockades was a better indication of what we may expect, than the escape or entry of a small proportion of the flying blockade runners specially built for the service. But surely it is certain that, setting aside for the pre- sent the effect of torpedo-boats, no squadron, not even a small one, could have evaded blockading squadrons, when the watch was so close that only a proportion of the attempts made by single ships were successful, and that these succeeded, not by escaping notice, but by running the gauntlet. The opinion of the Wilmington blockading squadron was that one-third of the attempts to run the blockade out or in failed ; and it was estimated that forty out of the sixty-six special blockade runners were captured or des- troyed ; but of course most of them had had more or less success before they ended their careers. Captain Long in his paper has devoted a good deal of space to the attacks which were made on the outlying forts of the blockaded harbours, but although it be true that the possession of these forts was a very important element in absolutely completing the blockade, I do not think that anything of that sort comes within the scope of the present paper. It seems to me that I ought to use only the actual BLOCKADE. 213 blockading: work of the Federals in order to form an opinion as to what our powers really are in this way ; first con- sidering steam alone, and then observing how far the advent of the torpedo-boat may modify the conclusions. I think I may consider it established that the chief, if not the only, element in allowing the escape of our enemies' fleets and squadrons in the last naval war was the adverse action of the wind upon our own. We are now going to examine briefly whether the Federal experience in actual blockading work in 1861 to 1864 at all resembles ours at the close of last century. We are going to ask the Federals in fact, as those most competent to tell us, whether the story we have heard tha,t steam has bridged the Channel is a true one, or whether, so far as their experience is con- cerned, the fact is not just the other way ? As I have said, when the Federals pronounced for a blockade of 3,500 miles of coast, embracing 189 harbours and inlets, they had practically no advantages to start with except the initial command of the sea. It is difficult to doubt that the whole conduct and issues of the Civil War would have been entirely different had this command of the sea been seriously disputed. It does not appear im- possible that had the arrival of the " Monitor " in Hamp- ton Roads on the night of the 8th March, 1862, been de- layed sufficiently to have allowed the " Merrimac " to com- plete her victories, the initial command of the sea, on which everything hung, m.ight have been lost. But having the initial command, the Federals proclaimed the blockade, and proceeded to the sealing up of every harbour, creek, and inlet leading into the Confederate ter- ritory. At first, as might be supposed, there was no par- ticular plan. Ships were sent as they could be procured off the principal ports — Wilmington, Charleston,. Savannah, 214 ESSAYS ON NAVAL DEFENCE. Pensacola, Mobile, New Orleans, Sabine Pass, Galveston, &c. The command was originally divided into the Atlantic and the Gulf squadrons, biit latterly, when the blockading forces became numerous, the Atlantic command was divided into two, the North and the South ; and the Gulf command also into two, the East and the West. At first the blockade was a mere hovering off the ports by vessels which did not remain long and passed on elsewhere ; but soon, as ships of all sorts, sizes, and shapes, sailing as well as steam, began to accumulate, regular systems were adopted — systems which appear to me to have rested on the idea of " sealiug up,'' and which would not have been the same had the ideas been of " masking" or " observing," though they obviously included both. There was the old system of the in-shore and the off- shore squadron, with the difference that the in-shore squadron was the important one, and was continually pressed closer and closer in, while the outer squadron was spread over large areas as a sort of wide-meshed net to catch the fish which either had escaped or might escape through the other. The in-shore squadron was sometimes at anchor and sometimes under way, according to the geographical and other conditions. In the approaches to Charleston (Fig. 3) the in-shore squadron was in the first half of the war kept altogether outside the shoals, the off-shore squadron being beyond it. The Beach channel appears to have been the favourite one both for the entrance and the exit of the blockade runners. The attempts were always made at night, and there is no sign of much evasion in the matter. The ships appear to have been always seen, and always attacked both by the in-shore and off-shore squadrons ; but they trusted BLOCKADE. 215 to their speed and to tkeir lack, and dashed through the in-shore squadron and out to the off-shore squadron, only being run ashore, rammed, boarded or otherwise captured, in a proportion of cases. The in-shore squadron was generally forbidden to chase. If the ships could succeed in barring the progress of the blockade runner outwards, well and good; but if they missed the opportunity, they had to leave it to the off-shore squadron to chase. There was very little warning either way. The entering blockade runner might very often escape notice altogether of the off-shore squadron on dark nights, and if so she was amongst the in-shore squadron without any notice whatever. Issuing from the port, it was certain that very little warning would be given. There was no such complete and accurate system of night signals as the world now possesses, though it had been designed a year before the Civil War broke out. The rough appliances of rockets and blue lights, incompetent to do more than give general warnings, were the signals most in vogue. As the blockade-runner showed no lights, it was only the ships who were close to her that saw her at all, and mere general alarm signals from these ships were not of any use in directing the course of blockading ships at a distance, and there must have been a want of concert which a more accurate and complete system would have removed. But, again, we must recall the fact that it was sealing up which was aimed at — actual blockade. It was not the defence of the Federal coasts or the Federal shipping which caused the assemblage of such numerous blockading squad- rons; it was injury to the Confederate territory, the cutting off its supplies, and especially its supplies of con- traband of war, that was the Federal object. It was the 216 ESSAYS ON NAVAL- DEFENCK. ingress, as much as, or perhaps more than, the egress which was to be checked. Hence a disposition of the ships blockading which might not have obtained had the object been the masking of war fleets, squadrons, or single ships. The concentration of a large in-shore squadron close to the entrances of harbours would not be the most obvious arrangement for observing or masking. .The strength would be in the wrong place if these were the designs, because the blockade runner, whether ship, squadron, or fleet, had but to make the dash, and, if not stopped, would be free. The plan which would suggest itself where egress and not ingress was to be checked, would be but a few of the smallest, lightest, and fastest vessels, with the most perfect signal appliances, close to the entrance to the harbour, and the fighting ships proper in an arc-like chain in the oflBng. It would be the duty of one of the light observing vessels to follow the escaping vessels seawards, continually informing the off-shore squadron of the whereabouts of the chase, in order that a sufiBoient force might be concentrated upon it. We must, I think, never forget this double duty of pre- venting equally ingress and egress, which devolved upon the Federals, and we must put the question to ourselves whether, had egress alone been the thing to be stopped, there would have been even the proportion of exits which there were ? Blockade, I may repeat, is a vital operation to us only so far as regards egress. If we can prevent war ships escaping outwards we should be disposed to encourage their escape inwards as so much ofE our hands. But, as it was, blockade running at every one of the Confederate ports became gradually impossible, except to specially built and prepared vessels. Some of these BLOCKADE. 217 undoubtedly had wonderful success, which may easily support the arguments of those who say that the days of blockade are over. The late Hobert Pacha made six suc- cessful voyage to Wilmington in the " Don," but she was captured directly he left her. The "B.E.Lee," under the command of a Confederate Officer, who had been in the United States Navy, actually ran the blockade twenty-one times in ten months. On the other hand, we read of the "Nashville" lying for eight months iu the Ogeechee river blockaded by three gunboats, and utterly unable even to make an attempt to escape. As I used the escapes of large ileets and squadrons in the days of sailing ships to illustrate the looseness of blockades, so I may usefully illustrate the closeness of a steam blockade by one or two of the most striking escapes - of single ships. One of the most daring was that of the " Sumter " from the Mississippi on 30th June, 1861. (Fig. 4.) She was blockaded in Pass a Loutre by the " Brooklyn " and " Powhattan," off its mouth, but owing to the double duty which was thrown on these ships of guarding ingress as well as egress, on this particular day " Powhattan " was absent, and " Brooklyn " was in chase of a sail to seaward. " Sumter " seized his opportunity in broad daylight, and crossed the bar of the pass when the " Brooklyn " was 3J or 4 miles from it. She was reported to have 13 knots speed, while " Sumter " could only get between nine and ten knots. The " Brook- lyn " instantly made for the " Sumter,'' and it very soon became a stern chase, both being under sail and steam ; but the " Sumter " lying closer to the wind was able to compel the " Brooklyn " to furl her squaresails, and so to gain upon her. The " Brooklyn " soon gave up the chase, and 218 ESSAYS ON NAVAL DEFENCK. was never near enough to open fire on the Confederate ship. On another occasion, but this time in darkness, the " Sumter " evaded the blockade of a single ship. She found herself in the open Bay of St. Pierre, with her stern tied up to the shore, and blockaded by the Federal ship " Iroquois.'' St. Pierre being a neutral port, the " Iroquois " could not attempt a really close blockade, but she made arrangements with a merchant schooner to display certain signals to her in the event of the "Sumter" making a move in the night. Captain Semmes thought that those signals would be two only, denoting that the " Sumter " was oE to the northward, or was off to the southward. In this belief the " Sumter " slipped her hawsers and made off to the southward under the land. Those on board her saw the schooner show two red lights, which they took to be a signal that they were off to the southward ; they could also make out the " Iroquois " with their night glasses, but in the shadow of the mountains as they were, they rightly assumed their own invisibility. As soon as they were assured that the " Iroquois '' was off full speed to the south, the " Sumter " turned round and made off full speed to the north, and got away without being chased. Ihe " Alabama " performed the same feat under the same commander a-year later. This time it was from Port de Prance, Martinique, the blockading ship was the " San Jacinto," which Semmes contemptuously calls an "old wagon." The night chosen was dark and raining, and the " Alabama " merely trusted to her luck, and ran out under a full head of steam by the most southern route without catching even a glimpse of the " San Jacinto." The double achievement of the " Florida " in breaking the blockade inwards and outwards at Mobile has attained BLOCKADE. 219 a just celebrity. She was only half fitted and half manned ; it was an absolute necessity that she should get into a Confederate port for completion, and Mobile was ciiosen. This was in September, 1862, and the ship was then at Cardenas in Cuba. The force blockading Mobile consisted of the " Oneida " and five gunboats, but at this particular time all were absent but the " Oneida " and the " Winona " gunboat. One of the gunboats had gone to take post off one of the Mississippi mouths wbich was left unguarded, and three others were away for repairs or coal. The frigate " Susquehanna " had been off the port, but she, too, was away for repairs at Pensacola. The " Florida " approached under English colours in daylight, and the " Oneida," not expecting a ruse, and sup- posing her to be an English man-of-war intending to ask permission to enter the port, steamed out to her. The " Florida" simply took no notice ; profited by the momen- tary hesitation of the " Oneida," and passed on at full speed. The " Oneida " was not long in opening fire, and planted several shot and shell in the hull of the " Florida," to which the latter made no reply, and she escaped across the bar, if not in safety, at least without fatal damage. Captain Moffit of the " Florida " was of opinion that had the " Oneida's " guns been better laid she would have ended her career there and then. This plucky commander made his escape through a blockading fleet of seven ships four months later, choosing a dark night and a northerly wind; she made out the blockading ships before darkness came on, when she moved down to the bar. They, too, saw her, but seem to have made very incomplete arrangements to intercept her. The " Oneida " remained at anchor and did not even weigh when the flagship, the " Susquehanna," made the signal 220 ESSAYS ON NAVAL DEFENCE. for a blockade ranaer. Another ship, owing to certain formalities enforced on board her, did not slip till half an hour had elapsed. Only one ship, the "Ouyler," really gave chase, which she followed up for the rest of the night and the whole of next day. But the " Florida " evaded her the second night, and was safely engaged in burning Federal vessels the second day. The risks that these and other single vessels ran in making these escapes ; the numbers that failed ; the inefficient and temporary character of so many of the blockaders ; all seem to show that it was much easier for whole fleets to escape to sea in the days of sail than for single ships in the days of steam. It may now be held, on the strength of the great American experiment, that it is as difficult, but not more so, to prevent the exit of single ships in the days of steam as it was to prevent the issue of vast fleets in the days of sail. I have been anxious to get the question clear for argu- ment as to the influence of steam alone on the question of blockade. Having done so — as far as the limits of time will allow — we must add to the question as it stands the influence of the torpedo-boat. That being, so far as I can see, the only change in the " conditions of warfare " as affecting all natures of blockade since the termination of the American Civil War. It is constantly held that owing to the absence of interior naval force in the ports blockaded by the Federals, they were able to take a position and to do things which would have been impossible had there been such force. I can grant that had the Confederates been in any way able to dispute the command of the sea with the Federals, the whole programme of the latter would have been upset, but the facts are against the theory that the Federals were BLOCKADE. 221 not liable to attack issuing from the blockaded ports. They were very generally liable ; they were often attacked from within, and sometimes were beaten ofE. Yet the command of the sea made an unfavourable issue of these combats a matter of minor importance. The only one where the issues were really critical was the attack by the " Merrimac," of which I have already spoken. In March, 1862, the Elizabeth and the James rivers were blockaded by the following Federal ships lying in Hampton Roads : — The " Congress " and the " Cumber- land," sailing frigates, were lying at anchor at the mouth of the James river; the "Roanoake" and "Minnesota,'' screw frigates, lay further down towards the sea; there, too, was the "St. Lawrence," a sailing frigate like the " Cumberland." The " Roanoake," though a steamer, was disabled in her machinery, and was unable to move except by the assistance of tugs. It was known to all these ships that up the Elizabeth river, at Norfolk, the Con- federates had nearlj completed turning a sister vessel to the " Minnesota " — the " Merrimac " — into a river-service ironclad. They knew also that there were steam gun- boats up the James and Elizabeth rivers, and they ex- pected an attack with the object of raising the blockade of the roads and rivers. On the 8th of March the " Merrimac," accompanied by two gunboats, came out of the Elizabeth river and pro- ceeded to the attack of the " Congress " and " Cumber- land " ; three ganboats came out of the James river to assist. The " Minnesota," under her own steam, got under weigh to repel the " Merrimac's " attack, but soon ran ashore in such a position that the " Merrimac " could not get within a mile of her. The "Roanoake" also weighed, and was presently towed ashore by her tugs. 222 ESSAYS ON NAVAL DEFENCE. There she helplessly watched the " Merrimac's " destruc- tive powers, and, being at length got afloat, dropped down to her old position. As she was dropping down, the " St. Lawrence " was being towed up to the attack of the " Merrimac," but she also presently went ashore, and took no efEective part in the day's proceedings. The " Merrimac " and her consort gunboats went straight up to the " Cumberland." She fired into her, rammed her, and sank her in a very short time. While she was thus destroying her, the gunboats opened so heavy a fire on the " Congress " that she was fain to make sail and run ashore, where she was afterwards burnt by the " Merri- mac's." shells. On the approach of darkness the "Merri- mac," satisfied with her day's work, withdrew to her own side of the river. She felt herself in command of the sea and of the situation, and designed to complete the work next day at her leisure. But froin the sea, at 9 o'clock that night arrived the "Monitor," the Federal answer to the "Merrimac"; and when next morning she got under way to settle the business with the " Minnesota,'' still on shore, she found beside her a little new-fashioned engine of war with scales as hard as her own, and with guns whose shot, though they could not penetrate, were at least able to break up her plating. The " Monitor" was, in fact, able to cover the " Minnesota," owing to the shallow water in which the latter lay, and in the result the " Merrimac " withdrew to Norfolk without having added at all to her victory of the day before. The Confederates had lost the command of the sea and had failed to raise the blockade. In April, 1864, the squadron blockading the Roanoake river knew that they might expect an attack from the "Albemarle," an ironclad which the Confederates had BLOCKADE. 223 constructed up the river. The Federal force was only two small steamers carrying each a rifled 100-pr. and five or six 9-in. smooth-bores ; and two tugs. On the 18th of April the " Albemarle " came down the river by night, made straight for one of the Federal ships — the "South- field" — rammed her and sank her, the crew escaping to the other which was alongside her. This ship, the '' Miami," and the tugs, then disappeared beaten down the river, but they remained at its mouth, while the " Albe- marle " lay alongside the wharf at Plymouth. The squadron off the mouth was reinforced by three more powerful steamers, and, on the 5th of May, the " Albemarle " came down and fought an indecisive action with the whole of them, which, being without distinct advantage to her, left things as they were. As is well known, she was a few months later destroyed by Gushing with a spar torpedo, while she lay alongside the wharf, miles up the river at Plymouth. A bold attempt to break up the blockade at Charleston was made in January, 1863. Two ironclad rams which had been prepared inside the harbour — the " Chicora '' and the " Palmetto State '' — taking advantage of a thick haze, crossed the bar, and boldly approached the numerous vessels — ten or more — outside, which were spread over an arc five or six miles in length. In a very short time the Federals, " Mercedita " and " Keystone State," had hauled down their colours. Tlxey were on fire and leaking, while the rams were uninjured; but not being taken possession of, they were recovered by the Federals. The fight lasted from five till half-past seven in the morning, and then the rams returned into port. The "Atlanta" was an ironclad converted from her old service of blockade runner by the Confederates at 224 ESSAYS ON NAVAL DEFENCE. Wilmington. In June, 1863, the "Monitor," "Wee- hawken," and " Valiant," had knowledge that they would be attacked by the "Atlanta," and .on the 17th they advanced to meet her as she came down the river. The whole thing was over in a few minutes. The " Wee- hawken" fired five shots from her 11-inch and 15-icch guns ; four of them struck the " Atlanta " and did her such damage that she immediately hauled down her colours. The blockading squadron at the head of the passes in the Mississippi (Fig. 4), consisting of two sailing sloops, a steam sloop, and a paddle steamer, were driven down the passes on the 12th October, 1861, by the ram " Manassas," escorting fire rafts. Not much damage was done by either, but it was not considered feasible to maintain the position, and the blockade was in consequence partially raised. Galveston had been taken possession of by the Federals, and became the base of the blockading squadron. In December, 1862, they were led to expect a combined attack by Confederate ships and troops. The former were two river steamers armoured with cotton bales. They captured the " Harriet Lane," and the "Westfield" was abandoned and blown up. Galveston fell again into the hands of the Confederates, and the blockade was raised. From this brief review it appears that the presence of the blockading forces was ilearly everywhere contested from the inside ; and that though it may be true that neither of the combatant forces were on a large or efficient scale, yet proportionately, the Confederate efforts were never to be despised, and often they were critically near success. What they wanted and never had was the power of attack from the sea, and it is obvious that, as I BLOCKADE. 225 have already remarked, eyea a temporary power of that sort might ha\e changecl the whole face of the war. If the naval forces of England should have to engage in blockading operations against a naval Power, they would in the first instance be liable to attacks similar to those which the Federals experienced. But undoubtedly the particular force which promis:s to interfere most with blockaders is that of torpedo-boats, I must not say torpedo- vessels, for if torpedo- vessels are to take a large place in war, they will take it in the open sea, and as the equals of any other form of open sea naval force. That is to say, they will be the rivals of the battle-ship as at present developed, and aim themselves at becoming the fleet-ships of the future, as claimed by M. Gabriel Charmes. But the torpedo-boat does not in any way claim to take the place of the battle-ship. It tends to operate outwards from the land, and not inwards from the sea. It is more a prospective terror than an open match for the ironclad ; and its cheap- ness combined with its assumed destructive powers makes it especially the weapon proposed for the driving ofi of masking or observing forces in the operations of blockade. It is, as I have said, not uncommon to hear naval officers — and some of the best informed— express the opinion that the torpedo-boat has made blockade a thing of the past. I do not think a calm well-reasoned judgment can accept this view. It is almost obvious, however, that if the Gon- f dderate ports had swarmed with torpedo-boats, the in-ahore squadrons could not have been safely so numerous, nor could they have pressed in so closely, nor so perseveringly. But I have endeavoured to show that we may be misled by the American experience. To us the sealing up of the enemies' ports can rarely be the object. It was, for America, part of the " Anaconda " policy— a policy resting on the Q 226 ESSAYS ON NAVAL DEFENCE. power of almost entirely surrounding the enemy with, an impenetrable wall. We are not in a position to attempt such a thing with any country, and consequently our blockade will seldom extend beyond masking and observing — to measures of defence, not of attack. What are the necessities of this policy ? Not surely large in-sliore squadrons ? A single observing ship close in to the port, designed to evade the most modern forms of attack, and with her signalling powers developed to the utmost, is all that is necessary for all purposes of observing, when she is in communication with the real force off-shore. We see the bases of such observing ships in the new " torpedo catchers." They will have a speed which makes the actual attack of torpedo-boats remote ; they will have a draught of water, not only enabling them to press into the shallows about the port, but rendering the chances of a blow from the looomotivp torpedo uncertain. Three or four of such vessels forming an in-shore squadron, always closing in and laying quiet at night, and drawing off as day-light breaks in the morning, would keep quite as close a watch on the egress of the enemy as the numerous vessels of the Federals were able to do. They would naturally be powerless to prevent ingress, but as I have said, that would be immaterial to us. In the case of vessels or squadrons attempting to escape by night, it would be less the duty of these ships to engage them, than to hang on their flanks and continually report their move- ments by signal to the ofi-shore squadron, which would detach and concentrate sufficient force to intercept the runaways. If the in-shore observers were attacked either by like forces, or such as might be supposed superior, they would either fight them or draw them off, taking care however BLOCKADE. 227 that some of their number should evade action for the purpose of keeping up the watch. No doubt the work of these observers would require all the skill, daring, and perseverance that the Navy has always been accustomed to show, but it would not be of the harassing character which that of the Federal in-shore squadrons was. And this, simply because they would be relieved of the anxieties dee to watching ingress. There would be gallant fights, there would be reputations lost and won, but I am persuaded that the watch would be maintained. The experiments at Bantryand in the North of Ireland were not such as to dis- courage us. Nor is there anything in Federal or Con- federate experience against us. It may be true that dark misty nights will favour the enterprise of escape ; but they will also favour the closer and more intimate watch. The same veil which tends to hide the blockade runner out- wards, tends to hide the observer of his movements. But those who think that the torptdo-boat has destroyed the powers of blockade— that is, of masking and observing — think more of the fighting force— of the ofE-shore squadron — ^than of these specially prepared watchers. But here we want to recall that all questions of attack and defence are matters, not of dramatic romance, but of common sense and reason. The fleet proper need not ex- pect every kind of attack without notice. If its watchers fail to keep it warned, there is practically only the torpedo- boat attack which can be delivered as a surprise. In this attack, the net defence, though perhaps not a perfect one, is yet a considerable safeguard. I know of no reason why this net defence should not be trusted to at night and in all ordinary moderate weather. I do not know why the ships of the fleet cannot be maintained in such a fair approach to order, with their engines occasionally moving, Q 2 228 ESSAYS ON NAVAL DEFENCE. and their nets down, as may make a surprise by torpedo- boats a thing to be less feared — even if our commanders did not go so far as Hobart Pacha in their contempt for this form of naval warfare. A hostile fleet can hardly drop from the clouds on a blockading fleet so situated, but were such a thing to happen, drill should make the passage from the condition of waiting torpedo-boat attack, to bristling with life and movement on the approach of a fleet, a very rapid one. Very bad weather, or even bad weather, is of itself a security against torpedo-boat attack. And then we have to recollect that for the blockaded enemy all attack is a matter of reflection and reason. He will not deliver it in any form against any part of the blockading forces unless there is at least a chance of success. No doubt his efEorts against the in-shore ob- servers will be more or less incessant — when he can find them. But I take it that the escapes of the " Sumter " and " Alabama," which I have narrated, tend to remind us that small vessels designed to be hidden are not always immediately discoverable. The chances, in fact, are even for both sides. If the weather is clear, the watchers can keep their watch at greater distances. If it is thick, they can close in with the less chance of being discovered. Clear weather and thick weather do not assist or hinder one side more than the other. And it is so with the off-shore fleet. A torpedo-boat flotilla will not quit the harbour for the attack unless there be some reasonable hope of finding the off-shore fleet, and this need not disclose itself except in answering the signals of the iu-shore observers. But this disclosure presupposes warning, and is so much against the hopes of the torpedo- boat flotilla. BLOCKADE. 229 These are tlie general reflections which my historical examination of this most momentous question has called np in my mind. They are, if -well founded, very encourag- ing, but my whole paper seems but to utter but a single warning. Keep the command of the sea as you value the national life. With it you can do everything. Without it you will speedily be blotted out from the list of great countries. 230 CHAPTER VI. CONTOTS: ARE THEY ANT LONGER POSSIBLE?! In addressing ourselves to answer the que8tion.propounded in the title of this paper, it would appear desirable to ascertain clearly what is meant by the term "Convoy," and what are the limits bounding the action of that which we mean by the term. I think we shall observe that in some senses the meaning of the term is very closely defined and the boundaries of its action very clearly marked out j while in others a considerable amount of generality and even vagueness seems to surround it. " Convoy " has three distinct meanings, not only in popular language, but in official and even in legal termin- ology. The word is applied to denote equally the merchant ships guarded by an armed force ; the armed force itself ; and both the armed force and the merchant ships guarded when considered as one body. It is, however, a curious thing in law, that though an armed force may be efiectually guarding a fleet of unarmed merchant ships, it is not a " convoy " unless it has been duly appointed to guard the merchant fleet by some authority competent to order it to do so. This competent authority seems always to have been either the Admiralty or the Commander-in-Chief on the station. 2 > Written in 1887. ^ Abbott: "Law relating to Merchant Ships and Seamen." 1802. p. 188. ' CONVOYS. 231 Again, a ship may weigli in company withi an armed force properly appointed, and as part of the fleet of merchant ships guarded by sach armed force. She may keep com- pany, and to all outward seeming form ^ part of the convoy, and yet not be a part of it. She would not, in the eye of the law, be under convoy, for instance, unless she had ob- tained, or done her best to obtain, sailing instructions from the offiosr commanding the armed force. She might have obtained them, and yet if she had failed to obtain the necessary appliances — flags, vanes, (fee, for instance — which thjse instructions enjoined she would not be under convoy .1 These appliances 33em to have been in the discretion of the authority ordering the convoy, as to quantity and quality. Possibly they may have been variable in the dis- cretion of the officer commanding the armed force. I have noticed a case where Vice-Admiral Waldegrave, in 1798, laid down stringent regulations, when he was in command of the Newfoundland station, making certain provisions of sails and of anchors and cables compulsory on the ships to whom he granted convoy. He even went so far as to have the merchant ships inspected. Complaints having apparently arisen, he appealed to Lloyd's, and Lloyd's warmly thanked him. There is no hint that he had not the power to enforce his directions on the merchant ships, under penalty that, if captured, the owners could not recover from the underwriters on policies where the warrant was " to sail with convoy." 2 Five things, in fact, were necessary to make a legal convoy : — "■ Abbott, as abo7e ; Marshall on lasarance ; WAtotA's " Insurance Cyclopaeiia," 1873. 2 "'^xv. Caron.,"I, p, 81. 232 ESSAYS ON NAVAL DEFENCE. 1. It nmst be regular, under an oflBoer properly appointed by Government. 2. It must be from the rendezvous appointed by Govern- ment. 3. It must be convoy " for the voyage." 4. The master must have proper convoy, or sailing, in- structions, and must do and obtain all things that are en- joined to be done and obtained by those instructions. 5. The ship must be with the convoy till the end of the voyage. Gases are given illustrative of this legal interpretation of the term convoy. Thus a ship, after waiting a con- siderable time for convoy to pass a port, joined one off it in a gale of wind, and therefore could not communicate with the war-ship to obtain her instructions. This ship being captured before she had an opportunity of getting in- structions, payment of the insurance was resisted on the plea that she had not fulfilled the warranty of " sailing with convoy." It was held, however, that she had done all that was possible to obtain the instructions and was legally sailing with convoy. The foregoing tend to show how narrowly the limits of the term convoy may be drawn. It may now be shown how widely, even how vaguely, the word has been legally defined. Thus in reference to the third of the five conditions mentioned above, we are told that " convoy for the voyage " did not necessarily mean for the whole voyage from port to port, but only for such part of it as the Government may determine ought to be prosecuted under escort of an armed force. But this widening of the term is immedi- ately corrected by the well-established dictum that a policy of insurance with warranty to sail with convoy was void COKVOYS. 233 by default, whether the default was with the ship or with the Government.! It may be gathered, therefore, that Government decided on the amount of protection proper to be given to convoy. That there was still convoy, though there was no protec- tion, in all cases when that protection was authoritatively withdrawn. But then there was no convoy when protec- tion was withdrawn without authority, either by accident or default. Though it does not appear that it was in past naval wars at all usual to leave a convoy wholly without protection at any period of the voyage after weighing from the rendezvous, yet the existence of the legal dictum seems to cover and admit the fact of the practice. But again, in a curious way, ships might be legally under convoy though there never had been any intention of pro- viding them with an armed escort. This is shown in cases where the rendezvous appointed by Government was not the port of original departure. The Downs, for instance, was often the rendezvous, and if a ship was captured on her way from a northern port to join convoy at the Downs, she recovered from the underwriters when she was " war- ranted to sail with convoy,'' though she had never seen an armed ship. In the year 1747 a convoy was appointed to rendezvous before sailing at St. Helens. A ship departing from the Thames to go to the rendezvous was captured on the way there. Nevertheless, it was held that she was sailing with the convoy in the terms of her policy, because she was doing that which the Government providing convoy had enjoined her to do. Government never proposed to give her armed protection from the Thames to St. Helens, but ^ Walford art. " Cotvfy.'' He sa; s the law books "swarm with Cases." 234 ESSAYS ON NAVAL DEFENCE. only on and after leaving St. Helens. She therefore re- covered from the underwriters, because, though she had no armed protection, Government had not proposed that she should have any over that part of her voyage. Convoy, oddly enough in its legal sense, does not appear to involve the actual presence of an armed force, but obedience to the injunctions of Government with reference to the protection of commerce by the ships engaged in it. It appears almost as if all the laws of convoy — all the powers of recovery of insurance, and all the forfeitures of the same — might be revived and follow in the next naval war, even though convoy in its narrower sense might never be revived. No doubt the whole of the conditions — legal and other — under which the practice and principle of convoy were applied in the past have been seriously modified. It may be difficult to say how seriously the repeal of the Naviga- tion Laws, and the revolution in the commercial ideas of statesmen that this repeal heralded, have affected this question, but there can be no doubt about the magnitude of the change. Though the germs of these laws are easily discoverable in earlier legislation, it was not till 1650 thai the Parliament of Cromwell prohibited the traffic of ships built or manned in foreign ports, with the plantations in America, and not till the following year that the famous Act of Navigation was passed. This Act, specially designed to injure the immense carrying trade of the Datoh, provided that all produce of Asia, Africa, and America should be excluded from the British Islands and the Colonies unless it was imported in English-built ships, which were commanded by an English master, and manned by a crew of which the greater part were English. Nor could European produce CONVOYS. 235 he imported in foreign ships unless such ships were bond fide belonging to the countries producing the articles imported. This clause specially struck at the Dutch as the carriers of the world. These laws, with occasional modifications, remained in force, or were re-enacted, down to the year 1849, but by the legislation of that year the Privy Council retains discriminating powers in favour of English ships. As is well known, however, the powers are dormant, and the carrying trade in foreign commerce to and from all ports under English jurisdiction is abso- lutely free. Thus in former naval wars, British ships were under protective laws, and as a consequence were under more special orders and regulations than would now be con- sidered either proper or politic. Having no rivals who could step iu and take the carrying trade out of their hands, British shipowners were very ready to fall into the wishes of the Government; and British merchants and under ivriters accepted the leisurely and closely ordered methods by which Government thought fit to conduct the carrying trade of the country. Compulsory convoy, under p3ualtie.s not only of forfeiture of insurance claims but of direct fine, was recognised as the concomitant and conse- quence of monopoly in the carrying trade ; and at the outset of every war. Acts, differing little from each other, were passed, compelling all ships not speciilly excepted to sail with convoy if they sailed at all The last of these Acts was passed in 180.3, on the re- newal of the war with France, and, like its predecessors, was to be in force only so long as hostilities lasted. The preamble was : — " Whereas it will add to the security of trade to prevent ships sailing without convoy except in certain cases." The first clause enacted that : — " It shall 236 ESSAYS ON NAVAL DEFENCE. not be lawful for any ship or vessel belonging to any of His Majesty's subjects (except as hereinafter provided) to sail or depart from any port or place whatever, unless under the convoy or protection of such ship or ships, vessel or vessels, as shall or may bo appointed for that purpose.'' Then the penalty for sailing without convoy, or wilfully separating or deserting from it, was a fine of £1,000, or £1,500 if the ship were carrying naval or military stores. The penalty might be mitigated, but could in no case be less than £50 ; and it was recoverable from the " person in charge of the ship." Not only was the insurance voided by these statutable offences, but any person settling the insurance claim was liable to a penalty of £200. The masters of ships had to execute a bond not to sail without convoy, and not to separate after sailing, before their ships could be cleared at the Custom- House. The exceptions to the scope of the Act were : — Any ship not required by Act of Parliament to be registered ; any ship licensed to sail without convoy, and I think these were often such as specially armed themselves ; any ship proceeding with due diligence to join the convoy from the port or place at which the same shall be cleared outwards, in case such convoy shall be appointed to sail from some other port or place, except, nevertheless, as to the bond hereby required to be taken upon the clearance outwards ; any ship belonging to the East India or Hudson's Bay Companies. It was further provided that the Act was not to be extended to ships sailing from foreign ports where there was neither convoy nor officer to appoint one. Vessels from Newfoundland with fish might, except in certain cases from the port of St. John's, sail without convoy or licence. By the same Act the Admiralty was empowered to give CONVOYS. 237 notice to mastars to provide themselves with " flags, vanes, and other materials'' necessary for distinguishing their vessels, and there were the usual provisions as to the SBitting up of actions and the disposition of the penalties recovered. Such appear to be the main features of the law of convoy, resting as we have seen upon the Navigation Laws, but how far resting, a layman might find it difficult to determine. While this basis of law has disappeared, the vast changes in the mode of propulsion, and in the course of trade which have taken place, form almost as complete a revulsion of conditions as the legal status exhibits. It is impossible now to conceive a set of conditions which, in the middle of last century, gave rise to the following case : A Dutch ship bound from Holland to several Italian ports, during war between France and Holland, received a cargo for those ports and sailed under convoy to Portsmouth. There she waited a year for further convoy. Obtaining it as far as Cadiz, she lay a second year there, and then sailed for Italy and delivered her cargo. The master brought an action against the owners of cargo for the wages and victuals of the crew during the two years, and he gained his cause. No doubt much of the foreign trade in sailing ships is conducted somewhat on the old princi- ples of yearly voyage, but with steam-ships the voyages are as frequent as they can possibly be made, and the only delays allowed between the voyages are due to necessary repairs, to survey, to recoating the bottom, coaling, and obtaining cargo. Even did the state of the law now permit such com- plete Governmental supervision as the Convoy Act of 1803 reveals, it seems impossible that it could take a 238 ESSAYS ON NAVAL DEFENCE. similar form, but before discussing this point, it may be- wise to glance briefly at what convoy meant and led to in practice about one hundred years ago. Most students of naval history will readily recall the fact that the great battle of the 1st June, 1794, arose out of the question of convoy. The French and English fleets fought in the month of June, and on a spot some 250 miles west of Ushant, first because there was a French convoy expected from the United States, and, secondly, because of the existing necessity of convoying clear of the Channel, an English merchant fleet. The French war fleet was present to receive and escort home the valuable merchant fleet of 116 sail which arrived safely in France and without any help, a week after the battle. The English fleet was there because it was feared that a large convoy escort might fall into th& hands of the French if not succoured. Lord Howe sailed from Spithead in May with some thirty-four sail of the line, beside frigates, guarding ninety-nine sail of merchant ships which formed the East and West India and the Newfoundland convoys. The permanent guard for these ninety-niue merchant ships was two line-of- battle ships and four or five frigates. 0:ffi Falmouth, Howe directed 'the convoy to part company with him and proceed, but he did not trust them to their per- manent convoy only. Six sail of the line and two frigates, beside the permanent convoy, parted from Howe, and saw the East and West India ships to the latitude of Cape Finisterre before returning. Howe himself gave his thoughts to the home-coming French convoy, and after ascertaining _that the grand fleet had not left Brest, cruised for a fortnight to the westward, where it was supposed likely that the French convoy, slenderly pro- CONVOYS. 239 tected by two seventy-fours, two frigates, and a brig, might pass. Ratarning to Brest, he found th9,t the grand fleet had put to sea in his absence, and he became aware that Montagu, the oflBcer who had been detached on temporary convoy duty, was very likely, from his position, to meet and be swallowed up by the great French ■ force. He pushed west for the position and the result was the battle. Prom this brief historical statement it is very easy to see what were the general features cf the practice of convoy in the last naval war. There was primarily a gathering or assemblage of merchant ships at some appointed rendezvous, but no special protection of war ships was provided between the port of clearance and the rendezvous. The ships so assembled, were, so far as their subsequent movements went, absolutely under the orders of the officer in command of the protecting force. They were compelled to obtain a copy of the sailing orders or regulations for the guidance of the convoy, and to provide themselves with all appliances which might be necessary to the effectual carrying out of those orders. The Government, on its own part, provided an over- whelmingly strong escort for the earlier part of the passage, where an overwhelmingly powerful attack might be expected. As the voyage progressed, the temporary, and mora powerful escort, gradually fell away, until at some selected point, far enough at sea to be presumably beyond the reach of the serious attack by the enemy, the large temporary force bid farewell, the aggregated fleet of merchant ships broke up into its component parts, and each part under its own small guard, made the best of its way separately to its destination. Just as the exit of the merchant fleet was thus specially 240 ESSAYS ON NAVAL DEFENCE. and strongly protected, so was its return. The French and American merchant fleet, of which we have spoken, was to hav3 been accompanied by two line-of-battle ships and two frigates across the Atlantic ; and more than a month before it arrived, five sail of the line sailed from Rochefort to join it, and escort it home. The same methods were always usual, and concentration of force on both sides was a usual sequence. In August, 1793, Lord Howe took his whole fleet from Torbay to escort the Newfoundland ships clear of the Channel dangers, and to meet and escort the West Indian fleet home. Having effected both these objects he returned. Sir John Jervis sailed in November, 1793, with four sail of the line, escorting thirty-nine vessels bound to the West Indies, and thereupon the French detached six fast ships from Brest to intercept him. In April, 1793, Admiral Gell, sailing from Spithead with a squadron, detached a 74 to St. Helena to meet and escort the East Indiamen home. Admiral Cosby earlier in the year •escorted a convoy clear of the Channel with six ILne-of- battle ships, and then quitting it, left one line-of-battle ship to continue the escort to the West Indies. Such illustrations show us what convoy meant in prac- tice in the broad acceptation of the term, and our own in- stincts suggest to us that nothing of this nature will take place in the next naval war. But as we have to show that our instincts are not misleading us, it will be well to con- trast some of the practical conditions bearing on convoy about one hundred years ago with those existing now. And first as to the question of speed. The French and American merchant fleet, whose expected arrival led to the battle of the 1st June, and the safe arrival of which that battle was in the opinion of some historians the cause, CONVOYS, 241 sailed from Norfolk, in Virginia, on the 2nd of April, and did not arrive in France till the 12th of June, making a voyage, therefore, of some 3,000 miles in seventy-one days, or at the rate of about forty-two miles a-day, or less than two knots an hour. Even Nelson, in chase of Villeneuve, could not push his fleet at a greater speed than about three knots per hour. Five, or even six times this latter spaed would not be a remarkable achievement for a modern Atlantic liner. Concerning the number of ships requiring convoy about 100 years ago and now, the case is not so strong as against the possibility of convoy in the old sense. The increase of tonnage has mastered the increase of numbers to a great extent. The average tonnage of ships engaged in the foreign trade in 1792 seems to have been no more than 134 tons, whereas in 1885, the average foreign trade sailing ship was 815 tons, and the average foreign-going steamer, 1,132 tons. But the numbers of clearances have not risen pro- portionately with the tonnage. In 1792 the long-voyage trade appears to have reached thirty sailings daily from all ports in the United Kingdom, and for the whole foreign trade the daily sailings appear to have reached thirty- eight.l In 1885 the average clearances of the foreign trade in sailing ships was twenty-two ; and in steam-ships seventy-nine ; the two together reaching one hundred and one daily sailings. Apparently every steamer employed in the foreign trade, when freights are good, is cleared, on an average, six times in the year. But the average sailing vessel trading to 1 The figures for 1885 are indirectly from the statistical abstract by dividiDg the average tonnage into the tons cleared. The figures for 1792 are from a paper by S. Cock, commercial agent to the Cor- poration of Liverpool in 1801. E 242 ESSAYS ON NAVAL DEFENCE. foreign ports is only cleared one and a-half times a year. That is, with foreign trade steamers the voyage lasts two months, while, in the sailing vessels, it lasts eight months. A great deal of the sailing trade now follows the old rule of the yearly voyage, including the delay for refit and to collect cargo, and as the sailings of that trade have greatly diminished "itice the days of convoy, it is evident that, so far as sailing ships go, there are no physical disqualifica- tions which would prevent its revival in the next war. It is not at all impossible that if convoy could be pro- vided at the beginning of the Revolutionary War with Prance for an outgoing trade of twenty-five or thirty ships daily, or a suflBcient proportion of them, it could also be provided nnder the same system now, for an outgoing trade of one hundred ships daily. Nor would the assemblage of steam fleets or merchant ships at fixed rendezvous, or the conduct of such fleets across the oceans, be one whit more difficult now than they were 100 years ago. On the con- trary, steam is in everyway in favour of a revival of convoy, and if nothing else prevented such revival but the change in the mechanical condition of trading ships, convoy in the next naval war might be expected to revive. But as I have said, the repeal of the Navigation Laws has entirely altered the state of the case, and though the Crown has power to re-enforce them to a great extent, it is not thought likely that public opinion would demand its exercise. The real reasons why we must suppose convoy on the old system to be dead beyond recall are the changes in the course of trade and in the course of opinion. Opinion, thoroughly expressed against the system of convoy, showed itself as early as 1811, and a Mr. Richard Hall Gower, in some "Remarks relative to the Danger CONVOYS. 243 attendant on Conroys," puts the whole case for the sailing ships of that year as he might find it for the steam fleet of this year. He says as a preliminary, that security depends on a just application oi force and flight. But flight must be considered prohibited on account of the order for sailing with convoy, and there remains only the force which is re- presented by the men-of-war guarding the merchant ships. Again, convoy is the occasion of loss in the gross. When merchantmen sail singly, they can only be captured singly, but when they sail together, a superior force to the guard may capture it, and the whole convoy with it. As illustrations of these positions, we have, at the period of history already referred to, one or two incidents of which we may take note. Thus the squadron of fast ships which had put to sea to intercept Sir John Jervis's convoy to the West Indies, after nearly falling victims to Lord Howe's fleet, which they took for their expected prey, were recompensed for their alarm by meeting our Newfound- land convoy, and capturing no less than seventeen sail. Villaret Joyeuse, issuing from Brest in May, 1794, cap- tured eighteen or twenty ships in one operation. In the same month a squadron of four line-of-battle ships and six frigates and smaller vessels of the enemy fell in with Cap- tain Troubridge in the " Castor," convoying ships from the Channel Islands to Newfoundland, and captured him and fourteen of his charges. These gains to the enemy and losses to us showed the futility of the system of convoy, and made it plain enough to some minds that unless the guard could be so strong as to defy attack, the danger of collecting a mass of ships under such a mockery of pro- tection was much greater than that of leaving the ships free to find their own way, and trust to the chapter of accidents. E 2 244 ESSAYS ON NAVAL DEFENCE. And it was not only this, but that the practice of always sailing with the convoy made shipowners and shipbuilders equally careless to protect cargoes by conferring speed on their ships, or by suitably arming them. Our author is fully alive to the inconvenience of the system of convoy to trade. Not only must there be delay in collecting a great fleet of merchant ships at the rendezvous, but once started, the whole trade is at the mercy of the slowest sailer, or the most obstinate blunderer. Instead of the system of convoy, our author, writing be it remembered in 1811, would, first of all, patrol tho Channel by a chain of cruisers, connected with the land by a chain of signal posts. The cruisers were to ply be- tween the posts, communicating with them and with each other, so that any attempted breach along the line would quickly be met by a concentration from both ends of it, and no part would be unsupported. The foreign trade, thus guarded, but not convoyed, clear of the Channel, would then be free to pursue its way, but the recommendation was that the stems of foreign-going ships should always be armed, and the men-of-war, instead of convoying them, should be concentrated at such narrow seas and straits, aad off such headlands as forced the trade to concentrate in passing. It must be admitted that this writer was possessed of considerable breadth of view, and there appears to be good reason to believe that even had steam never made its ap- pearance, convoy under the old system might yet have fallen into disuse, as these eminently practical views made tlieir way. Our survey, so far, may be said to make opinion rather than fact the author of the old and universal system of convoy. And then we may follow up this thought by re- CONVOYS. 245 fleeting that it would be opinion rather than impractic- ability which would forbid the revival of convoy in a modern naval war. It is, indeed, obvious that even as we stand, the Government might, if opinion demanded it, employ numbers of the fast steamers which it is proposed to take up and arm in war, by way of convoy to the un- armed steam trade. There might easily be fortnightly, or monthly, sailing of convoy from the Thames, the Mersey, and the Clyde. The delays would not be so great, the dates of sailing would not be so irregular as they were, now that steam has the mastery of the elements. A steam fleet would be much more easily and safely conducted across the ocean than a fleet of even the most modern type of sailing vessels. Nay, further, a steam fleet of merchant ships is not the helpless flock of sheep that a sailing fleet must show itself on the approach of even an insignificant force of the enemy. "What could a couple of unarmoured cruisers do, if on approaching a fleet of a dozen mej'chant steamers, these apparently weaponless treasuries were to get into line abreast and make for the would be capturer at full speed ? If we can imagine the position for a moment, we shall find ourselves entirely in symp^thy with the war- ships in considering discretion the better part of valour. But if it is opinion and not mechanical or physical fact which offers the greatest resistance to the revival of convoy in the old sense, it may be well to examine shortly where the difference is, and on what it rests. We have already seien that the Government control of the seaborne trade rested upon the monopoly granted to British shipowners by the Navigation Laws. Bat we have also seen it wisely disputed whether the Government method was the best possible for the security of the trade it assumed to protect from the hazards of war. Few of us 246 ESSAYS ON NAVAL DEFENCE. will now deny that tlie writer of 1811, whom T have quoted, had all the reason on his side. Thus it will follow, that if there be any now desirous of seeing the Crown exercise its powers in a greater or less approach to the protection of Bdtish shipping as against foreign competition, these per- sons may logically decline to advocate the revival of the old system of convoy in war. There is probably at this epoch no second opinion bat that a'steam-ship, with a good pair of heels and one or two quick-firing guns in her stern, runs less risk of capture in war when she proc;eds alone on her voyage than she would when forming part of a fleet of merchant ships trusting to the slender guard of a naval force absolutely iacompetent to meet the concentrated attack of the enemy which such a prize would invite. But still, in 1811, it must have been the opinion of "the underwriters which upheld the system of convoy. If the shipowner and merchant found the war risks were taken at a less rate when the warranty was " to sail with convoy," it is presumable that the pressure on the Government was in favour of the enactment of compulsory convoy. If the underwriters had concluded that the risk of sailing with convoy was really greater than that of sailing without it, the pressure on Government would have been against the Act. What Government will be asked to do if we are un- happily involved in a naval war will now, as then, depend upon the views of the underwriters. I have made some slight endeavours to ascertain what those views are likely to be, taking it in connection with those of shipowners, and in view of the remarkable proposition lately put for- ward by the President of the Chamber of Shipping — that Government should take the war risks. Able men whose business it has been to give some CONVOYS. 247 thought to that part of the subject now before us, have divided the carrying trade of the country into three branches, viz. : — 1. The fast steam trade. 2. The slow steam trade. 3. The sailing trade. It is the uaiversal opinion that a declaration of naval war would be the signal for the abrupt cessation of the sailing trade all over the world. This opinion is entirely con- firmed by the circumstance that when the Franco-German War broke out almost the whole of the German trade sought the shelter of neutral ports, and remained there till the war was over. There was, I believe, no attempt at convoy, and though the French blockade was anything but complete, commerce shrank from the risks attending attempts to break it. The slow steam trade is a very large one, and its usual speed does not exceed nine or ten knots. It is presumable that this trade is not largely engaged with perishable cargoes ; nor would it ssem to rest so much on early markets. If convoy were to revive in any shape, it would probably attend on this trade. The fast trade must be a growing one, as by the economies of coal following double, triple, and perhaps quadruple expansion, the cost of speed is continually les- sened, and bulk and weigjit of coal necessary to carry a certain bulk and weight of cargo is continually decreasing. I find that in the opinion of men very competent to judge, and more likely to be right as their own interest rests on the soundness of their judgment, we are close upon a great petroleum revolution. If petroleum is so close at hand as these authorities suppose, tbs stimulus to fast trade will be very great. 248 ESSAYS ON NAVAL DEFENCE. All the arguments used by the writer of 1811 whom I have quoted entirely apply to the steam-ships carrying on this fast trade. As war-ships are now constructed it would be almost hopeless for them to touch a fast trader at 15 to 18 knots. 1 Only accidentally by night or at breaking daylight could the ordinary war-ship hope to get near enough for her operations against the great Atlantic or Australian liner. Practically, if attack were contem- plated they must be made by similar ships, armed for the purpose. But considering the enormous value of the intended prize it is not unlikely that she herself would bear the tax of being well armed. Reverting for a moment to the question of the sailing trade, its extinguishment, even in the absence of war, is a thing certain. Though in the ten years ending 1885 the average tonnage of sailing ships engaged in the foreign trade has risen from 586 to 815, yet the numbers have fallen from 5,327 to 3,180.2 The fall has never been less than fifty-seven sail in one year, and in 1880 no less than 450 ships ceased to be returned as engaged in the foreign- going sailing trade. Remembering that the average steamer takes twelve freights in the year, while the average sailing ship takes only two and a half, in the foreign trade, it is manifest that the sailing trade will hardly bear the growing economy in working the steamer, and its decline may be even more rapid than it has hitherto been. And this is notwithstanding the fact that in a waiting market trade, freight has even been higher for sailing than for steam-ships now and then. ^ The great iaorease of speed given to the later war-ships has somewhat modified this ; but the increased mass of the Merchant steamer must be taken on the other side. — Ed. ^ The numbers in 1891 were 2,127 ships, averaging 1,142 tons. — El>. CONVOYS. 249 Such being the general conditions, what may be ex- pected from the attitude of the underwriters towards the shipowner and the merchant in war, and how would the interaction of these three great interests tend to sway the Government in the way of protection by convoy ? The underwriter on the one hand neither likes loss of business nor a class of business highly speculative. So far as I am able to see he does not dislike but finds his interest in a business which is moderately speculative. When war risks can be fairly well estimated, they will be taken at premiums which fairly measure them. It appears that war risks on German ships were at the outbreak of the Franco-German War pretty freely taken at very low rates — 5s. per cent., I believe, in instances. But a few cases of heavy loss speedily ran the premiums up. I have been told that underwriters who had taken German war risks at 5s. sold them again at £5, incurring thus a certain loss rather than run the risk of enormous uncertain losses. It has been very generally stated to me by prominent underwriters that the rates for American blockade runners were enormous, and that the risks were very commonly declined altogether. Some authorities have told me that, on the outbreak of a naval war with England, war risks on English ships would not be taken at any price likely to be oHered by the merchant or shipowner. The risks on ships jfnd cargoes at sea might be much governed by the proclamation of war. If no time was allowed by the hostile Power before the attack began on ships which had put to sea ere the declaration of war was published, there would be so little measure of the danger of capture to which such ships were exposed that only the more specu- lative underwriters would take them. On the other hand> 250 ESSAYS ON NAVAL DEFENCE. some authorities appear to think that, as in the Frauco- Oerman War, the premiums on war risks might not ba heavy. They would immediately be affected, however, by the earlier reports of captures, and, in my judgment, panic might easily be set up and kept up if the list of captures were early and heavy. It will be easily understood that the ground we are now on is the most interesting and the most important of all, for we are dealing with the formation in the City of that opinion which is bound to make itself felt, if not to force the action of the Government. But while it is the most interesting and the most important, it is also the most purely speculative on which the future of convoy rests. My inquiries have been necessarily of a very limited character ; I have to endeavour to express impartially the general sense of the answers to questions put by me in friendly conversation with some of the leading authorities who have most kindly, in all oases, given me the benofit of their experience and opinions. It may be hardly neces- sary to warn my readers that it is very easy for a person like myself to be wholly mistaken on intricate matters of this kind, and even unconsciously to misrepresent the views of those who have kindly expressed them. In some conversations I have had I have' come away with the idea that a declaration of war by England with really naval Powers would at first result in an entire paralysis of trade. It has been said to me that in that case war risks would not be taken at any price which the merchant and shipowner could afford to pay. Neither ships nor cargoes would leave our ports uninsured against war risk under the English flag, and hence stagnation, at least for a time, would follow. But I am bound to say that it does not seem to be the CONVOYS. 251 general opinion that our trade in English bottoms could suffer the restrictions that trade in German bottoms suffered in the Franco-German War. All the authorities discriminate between different classes of ships as to rates of premium for war risks. It seems certain they would be highest on sailing vessels and lowest on fast steamers. And there seems no doubt that a warrant to sail with convoy would now, just as it did in the last French war, enormously reduce the war risk premium. Bearing in mind that current opinion in the City will, in the absence of correcting experience, govern all these questions, I note, not without some surprise, one or two positions which appear to be taken up as axiomatic. War with the United States, in spite of her limited N"avy,l would be regarded as much more threatening to our ocean- caTrying trade than war with France, notwithstanding her relatively enormous naval force. I presume that the naval view would be the exact opposite to this. There appears to €xist a confidence in the security of the steam trader against capture by the steam enemy, which would not be allowed to the sailing trader as against the sailing enemy. Naval opinion might tend a little in this direction from the belief that the average steam merchant ship would generally have the heels of the average man-of-war. In another way the opinion might be supported. Even supposing the war-ships had the heels of the trader, the fall of darkness would tend much more to facilitate the escape of the steamer pursued by a steamer, than of the sailing ship pur- sued by a sailing ship. All points of the compass are open to the escaping steamer to steer upon ; there were always twelve points tabooed to the sailing ship. Then as the 1 Now increased, and increasing. — Ed. 252 ESSAYS ON NAVAL DEFENCE. speeds with steam are much greater than they were with sail, it follows that a changed course on the part of th© escaping steamer, not followed, becaase not seen, by the pursuing steamer, will put a greater distance between them in any given time than could be put under similar circumstances between two sailing ships. That is, the two sailing ships might still find themselves near each other at daylight, while the steamers might be hundreds of miles apart. Biit if the man-of-war has the heels of the trader with steam, most of these considerations relate to meetings late in the day, and none of them relate to the case of an unfor- tunate trader finding herself within shot of the war-ship when dawn breaks. Apart from these circumstances, I know of nothing which makes a steamer less liable to capture by a steamer, than in the old days, or even the days of the " Alabama," a sailing vessel was by a sailing vessel, for it may be remembered that nearly all the " Alabama's " captures were made while she was under sail alone. If this confidence should underlie the early trans- actions in war risks, and should turn out to be misplaced, the reaction would be correspondingly great. If we consider the position of the merchant and the shipowner in time of war, we shall probably find freights rising for the owners of fast steamers, (1) because of the existing opinion that they are less liable to capture, and (2) because of the limited number of fast steamers and the cessation of the sailing trade. A rise in freight would enable the shipowner to pay a higher premium for war risks, but it would impair the merchant's power in that direction. For all the trade now carried on in the slow steamers, and for all the " waiting market " trade now carried on in the large sailing ships, there would be no CONVOYS. 253 direct demand for freight in fast steamers. Indirectly the demand might come because of the idea of security from capture, which was shown by the lower rates of premium. If the slow steamer could be secured from capture, or if it were even the opinion that she was so secured, premiums on the slow steamers and. on the cargoes they carry might be expected to fall. It is here that T apprehend the possibility of a revival of something like the old system of convoy. I do not say probability, but possi- bility that Government might be pressed, in the interests of trade generally, to assist in specially securing that part of it which is carried on in slow steamers. If there were such pressure, it might be yielded to by the employment of the armed merchant steamers which the present Govern- ment is using such wise and far-sighted means to secure. It will be obvious that the case of the merchant is that which would press, and it would be for him a consideration whether the high war risk premium, or the delays surround- ing convoyed fleets, was the greater evil. If the under- writer were to be of the opinion of Mr. Gower in 1811, he might doubtless not lower his premium for warranty to sail with convoy. But I gather that the idea of safety surrounding the presence of a war-ship would weigh the scale down against the closer reasoning of Mr. Gower, so far as respects the slow steam trade. It is germane to my subject, and I cannot therefore avoid pointing out what a remarkable temptation to a wholesale transfer of flag the Declaration of Paris would offer under all these circumstances ; and, on the other hand, whether, in spite of all our present ideas of free trade, the Privy Council might not be pressed in the exercise of some of the powers reserved to it in 1849. A heavy transfer of flag might so alarm the country as tg 254 ESSAYS ON NAVAL DEFENCE. make it demand, reasonably or unreasonably, some protec- tion for the British, flag in order to check the transfer. 1 In America, the Confederate cruisers appear to have captured or destroyed about 175 vessels; nearly all sailing vessels, and not always very valuable. The result upon Federal shipping generally was a transfer during the four years of the war of 715 American ships to the British flag. And in the first three years of the war about 38 per cent, of the carrying trade of New York disappeared. America has never recovered that blow : and though it would bs a mistake to ignore the effect of subsequent pro- tective duties, and of a change in the material used in ship-building, it would be an equal error not to fear that a temporary loss of our carrying trade might be irre- trievable . I suppose it is all these considerations which have led some shipowners to think of an arrangement with the Government. They probably argu3 that, first of all, Gorernment would have better knowledge of the probable risk than would be open to the body of underwriters. It would ba further said that if Government took the risk, all its energies would bs turned to minimising it by a proper disposition of its sea forces. The proposal, as I understand, is not that Government should become an underwriter in the ordinary sense of the term, taking war premiums and accepting the war risks. The idea is that shipowners now, in peace-time, would consent to pay a yearly premium or tax to the Government, on condition that if naval war with this country broke out, fixed values should be paid to the owner of the ship if she were captured or destroyed by the enemy. ' The legal difficulties of transfer are, however, very great iadeecl. — ^Ed. CONVOYS. 255 I am told that shipowners would probably accept reason- able conditions at the hands of Government as to what would, and what would not, forfeit their claim to payment for capture or destruction by the enemy. But the whole matter is necessarily in a very crude state as yet. I have heard nothing as to what shippers might have to say of it, yet it is evident that unless the cargo could be insured as well as the ships, we should not have made much ad- vance. I believe that in one of our recent Russian scares, this revived proposal had some consideration in the minds of the authorities, but it evidently did not lead to anything definite. The matter is brought into close connection with our subject in view of a remark I made at the beginning of my paper, namely, that in its widest legal sense, the benefits of convoy fell to the ships which happened to be captured while acting " in obedience to the injunctions of Govern- ment with reference to the protection of commerce." If it is to become possible for Government to take a direct pecuniary interest in the security of sea-borne trade when the country is at war, it will certainly control in some way the movements of that trade. This control may, in legal view, replace the Act of 1803. Government will never accept the risks qf heavy payments, and leave the merchant ships absolutely free. Authority will, in consul- tation with trade, settle how its risks may be minimised with least interruption to the trade itself. It would appear that in the old days, ships which dared to be to a certain prescribed extent armed, obtained licence to sail without convoy. Government, in accepting war risks for a peace payment, might not impossibly demand a certain armament of the ships insured in war. It is impossible to say whether it would not enforce modified convoy in some cases. Ac- 256 ESSAYS ON NAVAL DEFENCE. cording to its thouglit-out sclieme of oommeroe guarding, it would demand to control the movement of trade. Falling back on our author of 1811, if Government sub- stitute for convoy a system of patrolled routes and strongly guarded centres, it might very reasonably call on the ships for which it was responsible to pursue without deviation the patrolled routes and to pass through the strongly guarded centres. It almost seems possible to me that, without taking any special responsibilities, the Govern- ment, through the law and the underwriters, might press upon shipping to fall in with its scheme for the defence of commerce. Thus the points raised by the question given to me as the title of the paper may have a wider significance than appears on the surface. Convoy rested more on the general opinion of the merchant, shipowner, and under- writer, in days gone by, than on the A.ct of Navigation — which again was the embodiment of opinion. Convoy never would be revived without any resuscitation of the Navigation Laws, if, in war, underwriters would accept risks of capture and destruction by the enemy of ships under convoy at a much lower rate than without it. It is true that the course of trade now, in peace-time, is such as to make the idea of convoy abhorrent. But suppose convoy to be the alternative to either a partial cessation of trade, or a transfer of flag? This consideration of the course of trade would fail to affect the question. Commerce is timidly sensitive. Were a naval war de- clared to-morrow, and if the capture of a valuable English ship were posted at Lloyd's the next day, what would be the effect of the announcement on the proceedings of ships loaded and about to sail ? If Government thereupon an- nounced that a couple of ironclads would sail from Spit- CONVOYS. 257 head to join the Mediterranean Fleet, and would afford the protection of their presence to any ships choosing to sail in company with them, would the merchant or the ship- owner interested in a loaded ship going to the Canal, de- cline the offer because their voyage would be delayed a day, a week, a fortnight ? These are questions City men must answer. No doubt if at a moderate premium the risk of capture was covered, the course of the trade would not be altered. But, as I understand, there is a possibility —though it may not be a probability — of sudden and heavy advances in the rates for war risks, and that these rates would be much lower where the warranty was to sail with convoy, I conceive something at least of the old practice might arise almost before we were aware of it. When the Federal war-ship seized Messrs. Slidell and Mason out of an English mail steamer, we despatched, in December, 1863, the " Melbourne " transport under convoy of the '' Orpheus " across the Atlantic. I suspect that at least Government troopers, transports, and store-ships would, in a naval war, be placed under convoy just as in the old days. And it almost seems that whenever the markets allowed of it the merchant and the shipovrner would ask for convoy at the hands of the Government just as in older days, unless they were well assured that the enemy's cruisers were entirely masked by our own fleets and cruisers. 258 CHAPTER VII. THE ATTACK AND DEFENCE OF FLEETS. 1 The subject I have andertaken to illustrate in to-night's paper is one of extreme importance at the present junc- ture. It is not only desirable that we should find our- selves prepared with some defiaite views on naval warfare in the open sea, when carried out with the ships and weapons now at our command, but it must never be for- gotten that the views we may form will, and do, actually govern the nature of the designs produced by our archi- tects, and the disposition of guns and other weapons on their floating carriages. It would therefore be a culpable error for any one treating of the attack and defence of fleets, to confine himself to questions of mancsuvring merely, as though ships were, like men, of an unchange- able type. Writers of the past on the subject of naval tactics, such as Pere Hoste, De Morogues, and Clarke of Eldin, might well be excused if they thus treated their science. But such a method is no longer permissible. Writers of our age, who assume in some sense to lead opinion, must remember that we stand at the cross-roads of naval warfare ; we are no longer edged in by impassable barriers on the smooth highway of progress. Many roads nre open to us, and we have to make a selection, guided ' Written iii 1871. THE ATTACK AND DEFENCE OF FLEETS. 259 by a not much, better trail than the Indian hunter finds in his forests. I am the more anxious to press this point forward, as I believe we are not suifioiently alive to the fact that the current view on the atcaok and defence of fleets is the foundation of all design in naval materiel. I say I think we are not sufficiently alive to this fact, because I cannot believe, were it otherwise, that we should rest content with certain instinctive ideas, on the subject of future naval war, and make almost no attempt to formulate our instincts, and separate where possible the chaff from the wheat. If I were to make the assertion that the designs of our ships arise more out of instinct and tradition than out of any comprehension of how they are liable to attack, and how they are capable of defence, I should at first raise a feeling of incredulous surprise in the minds of my audience. Tet I do make the assertion, and think that a few sentences in explanation will entirely remove the incredulity, while they will strengthen the surprise. Consider for a moment how you could re- but my assertion. What sort of arguments would you use, and what sort of facts would you produce to sustain the counter-proposition that our ships were designed to deliver certain specified and approved attacks, and to offer certain distinct resistances ? You would be constrained to rely on the general proposition that the ships were designed to use their guns, and perhaps their rams for attack; and their armour for defence against guns. Beyond this you could . not go j and you wiU observe that it is a very small step. The gun and the ram are presented to your view as possible weapons, because they are both traditional j you cannot build a war ship except on the supposition that she is to use both or either -of them. Oil the other hand your instinctive desire for 8 i 260 ESSAYS ON NAVAL DEFENCE. protection from shot has given you armour plating. In what respect you have advanced beyond instinct and tradi- tion can only be proved by ascertaining whether you appreciate the relative values of the two weapons provided, and have designed your ship in agreement with that relation. Take an illustration from the infantry soldier, which is temptingly apposite to the case in hand. He has two weapons, his rifle and his bayonet. Their relative value is established and known, and no projector would be mad enough to sacrifice one iota of the known value of the rifle to the problematical value of the bayonet. But who can say of any ship in our Navy in which the two weapons are combined, that her gun-power is properly sacrificed to assist her ram as the superior weapon, or that her ram-power is judiciously curtailed to admit of in- creased ordnance ? 1 For clearness of expression, I am leaving out of consideration the third weapon — the offensive torpedo — which it will be necessary hereafter to treat distinctly ; but is not my assertion, even in the case of any single ship called upon to attack, or defend herself from any other single ship, quite borne out by the elemen- tary considerations I have adverted to ? 2 If we go a step beyond the single ship, and glance at the preparation made in our ships for combined attack, or combined defence, we shall light upon a complete abne- gation of any such idea. But returning to the single ship, and avoiding the con- fusion of the double weapon in the same ship, think what is ascertained as the best method of carrying ordnance ? Is the " Monarch " or the " Hercules " the more powerful 1 This language, more than twenty years old, is still applic- able.— Ed. . , ' The looomotive torpedo was not considered when this paper was written, but it does not affect the aigument, — Ed, THE ATTACK AND DEFENCE OF FLEETS. 261 ship ? or would the 5,000 tons of the " Monarch," and her four 2o-ton guns, fall victims to the attack of five lightly clad ships of 1,000 tons, each carrying a single 25-ton gun ? Then if the ram be alone considered, what are the rela- tive values of speed and turning powers for attack upon a. willing adversary, or for compulsory defence 1 May speed be judiciously sacrificed to turning powers, and to what extent ? Or must speed be secured at all hazards, and turning powers only considered afterwards ? If we are not depending on tradition and instinct, then categorical answers are forthcoming to all these queries. But if no such things are -extant — which is unfortunately true — and if besides, very little efiort is exerted in the attainment of true solutions, then my position remains unassailed and unassailable. Now, what I want you to observe in all this is, that while we are very apt to think that the ships and weapons presented to the naval officer for his uses in a complete state, cause him to take particular views of attack and de- fence, and give rise to his speculations on' the subjeob ; yet the converse of this is the case. He first forms views of attack and defence, and these find expression afterwards in material products. It is the abstract gun, ram, and torpedo, which form his original idea of warfare ; the con- crete weapons do no more than modify views already out- lined in his mind. If his original idea is crude, unthought out, above all, if there are diversities of ideal, the results in a material form will give rise to vagiie uncertainties, and endless discussions, such as those by which we find ourselves now surrounded. It will be seen, therefore, that from my point of view I could offer you no more important or comprehensive ques- tion than that I have chosen as the title of my paper. 262 ESSAYS ON NAVAL DEFENCE. I had no soDnsr plottsd out what I thought should be said on an occasion like the present, the facts it would be necessary to put forward, the deductions it would be proper to draw, and the general line of treatment it would be desirable to pursue, than I became overwhelmed with the magnitude of the task before me. For just observe for a moment what a paper on " the attack and defence of fleets " might be expected to deal with. Think in what aspects a professional audience might justly call upon me to place the subject before them. There would first be the theory of the matter. You would expect me to set out the theoretical relative values of the gun, the ram, and the torpedo, as offensive or defen- sive weapons. Each must, therefore, be carefully and separately considered, and then considered afresh in their relation to each other. It would next be proper to look at the state of naval opinion at home and abroad on this question of relative value, and to note how it might coincide or difBer with the conclusions independently arrived at. The ultimate con- clusions, whatever they were, ought then to be applied to the combat between single ships of existing types, and from the whole discussion should be drawn the deduction as to how present ships fulfil the ideal requirements so far. I do not think I exaggerate when I say that any discus- sion of the attack and defence of a fleet is absolutely valueless prior to the analysis I have sketched out, but it is apparent that such analysis would fully occupy the limits of a single paper. The next step in the enquiry would be the theoretical methods of making a fleet mobile and flexible under the oitrjl of an adaiifil. The state of naval opinion at home THE ATTACK AND DEFENCE OF FLEETS. 263 and abroad should be applied here, as it was to the values of the weapons, and compared with the facts. After this, you might fairly call upon me to consider the ofEensive and defensive features of the various formations proposed or possible, and of the movements by which they are obtained; and here it would be necessary again to glance at the state of naval opinion on this head. Then, and not till then, should we be in a condition to place our- selves in the positio.i of a fleet attacking, or a fleet attacked, and so deduce the rules within which we must act to give the greatest vigour to our attack, and the greatest solidity to our defence. In facing these conditions which seemed to me unavoid- able, I had to consider how I should meet them. I might touch very lightly and inefficiently on each branch of the subject, and compress the whole of it so greatly as not to extend the limit of time allowed, but I felt it was not just to so great a subject, so very casually studied, to treat it in that cursory way. If I had had any further doubts about it, they were fully resolved when I found that I had written enough for an hour and a half's reading, and had -not so much as touched the fleet question at all ! Therefore, to my great regret, I come before you to- night under the false pretence of a misnomer in title, " The Attack and Defence of Fleets," has dwindled to the attack and defence of single ships, and if I receive your censure at the outset for my acknowledged shortcomings, I shall hope to modify it by showing at the conclusion that I was a helpless instrument in the hands of my facts. Without further preface, then, I shall proceed with the examination of guns, rams, and torpedoes, in the order and with the objects I have pointed out. 264 ESSAYS ON NAVAL DEFENCE. Guns. In my paper on " Modern Naval TaoHos " read here five years ago, sea-going turret-ships were not, and the discus- sion of the gun-power of a fleet was necessarily confined to broadside ships, whose fire covered an arc of three points before and abaft the beam. In my "Lessons from Lissa," also read here in 1867, the " Bellerophon " was our representative ship, and the cal- culations used to illustrate gun-power were drawn from her capabilities. The "Monarch" is now our representative sea-going ironclad, and she must do duty as our typical ship. In so using her, I am not prejudging the great cause of turret versus broadside, on the contrary, my opening remarks show that I do not mean to take the " Monarch " as a per- fect ship, and consider how a fleet of such ships can be best employed. I take the " Monarch " as my ideal, in order that I may not find myself dealing with an impossible type, and because the " Monarch " embodies in the highest degree the principle of construction and armament most opposed to that found efficient in former naval wars. All round fire is unquestionably the object to which so much is sacrificed in the " Monarch," and if I were to take a ship like the " Hercules " as my representative, I should flnd the struggle after all-round fire just as prominent there, but carried out under a smaller departure from old methods of construction. The " Monarch " has the fewest and heaviest guns of any sea-going ship in the Navy, and she exercises her gun-power over a larger arc than any other. She is the embodiment of the idea that the gnn is the decisive weapon at sea, to which all others must give place, and that this weapon is most powerful when THE ATTACK AND DEFENCE OF FLEETS. 265 mounted in limited numbers, of the greatest size, and with the largest arc of training. The question 1 propounded four years ago in my paper on the battle of Lissa was, " whether the gun was advanc- ing or receding in power as a naval weapon?" The illustration was whether the guns of the " Bellerophon," as against a "Bellerophon," were more or less powerful than the guns of a 90-gun ship against another of her class before the advent of ironclads. The -question to-night is, so far as guus are concerned, the same but carried a stage further. "Has the gun-power of the 'Monarch,' as against a ' Monarch,' advanced or receded from the position held by the guns of the ' Bellerophon ' against a sister ship ? " In the discussion of the earlier stage, I endeavoured to show by an analysis of the forces at the battle of Lissa, how enormously the gun was falling back before the increasing work it was called upon to do. My comparison was in the first instance, that under the old sj stem of building and arming ships, each Italian gun would have had only 50 tons of material to destroy in completing the annihilation of the Austrian fleet ; and each Austrian gun would have had only 93 tons of Italian shipping opposed to it. With the new methods of building and armament, however, under which the Fleets actually met, each Italian gun had 260 tons of material to destroy, and each Austrian gun 432 tons : that is to say, unless the guns at the battle of Lissa could give shot for shot of the light guns used in former times, and each shot were about five times as destructive, the gun had receded from its place as a naval weapon. 1 then proceeded to show, that so far from modern guns keeping up shot for shot with their prototypes, their speed of fire was very materially reduced, and that 266 ESSAYS ON NAVAL DEFENCE. one round in two minuteB was as rapid a fire as could be expected. A Lissa ship opposed to another, gave an average of 346 tons of destructive work. A " Bellerophon " opposed to a " Bellerophon " gives 600 tons of destructive work to be done by each gun. A " Monarch " opposed to a " Monarch " gives no less than 1,275 tons of work. If, therefore, I had reason in pointing to the recession of the gun from its place as a weapon, by the results of the battle of Lissa, what am I to say when I find it has now receded three times as i&v as it had then? I imagined that guns, then, supposing them to give shot for shot with the old ones, must be five times as powerful to retain their places. Now, on the same principle, I must imagine the " Monarch's" g^ns to be about twice as power- ful as the "Bellerophon's," or about eighteen times as power- ful as the old smooth bores, in order to keep their place in the race. If the " Bellerophon's " plating be considered to have a resisting power of 36, the " Monarch " has a resisting power of 49, which again tells against the g^ns. But, on the other hand, the " Monarch's " guns exert a striking force of 5,000 foot-tons at 1,000 yards, in lieu of 2,400 foot-tons which the " Bellerophon's " guns exert at the same range. Making a proportion, we find that the power of resistance has increased in the ratio of 1 to 1'3, and of attack in the proportion of 1 to 2. The net result in favour of the guns is 0-7, and, consequently, the net recession of the gun-power since the " Bellerophon's " time, is in the proportion of 1 to 1-3. Now, it seems that a shot from the 25-ton gun, fired at a range of 700 yards, having on impact an energy of 170 THE ATTACK AND DEFENCE OF FLEETS. 267 foot-tons per inch of shof s circumference, fails to penetrate the " Hercules'" tai^et. The "Hercules" target is, in resisting force to the "Monarch," as 64 to 49, and the energy of the "Monarch's" shot, at 1,000 yards, is 137 foot-tons per inch of circum- ference. The proportion between the figures show that the resisting powers of the " Monarch's " side against her guns at 1,000 yards are as nearly as possible equal to those shown by the " Hercules " on the occasion referred to ; that is to say, that a '' Monarch " firing at another " Mon- arch," will fail to damage her at 1,000 yards when her shots strike fair. But how little can we calculate on this result ? The general idea concludes that a ship will rarely present her broadside to be fired at. To be fair to both sides, suppose the shot strike at an angle of 45°, and the resisting power of the " Monarch " rises from 49 to 98. In other words, it is doubled. What possible prospect has a "Monarch' of deciding an action with another "Monarch" by means of her artillery, under circumstances such as these ? But we are only on the borders of the " Monarch's " powerlessness as yet. In my paper on Lissa, I endeavoured to show that at the utmost rapidity possible, the " Bellerophon " could not fire more than 4 rounds per gun in 6 minntes, or 28 rounds in all. I am informed that the " Monarch " does not calculate on a greater speed of fire in action than 1 round in 3 minutes per gun ; that is to say, the rapidity has fallen from 28 rounds in the " Bellerophon," to 8 rounds in the "Monarch " in 6 minutes ! We have no grounds for sup- posing that more than a trifling increase of accuracy has been gained, and, therefore, I must debit the guns with this further reduction, equal to 3-5 in their power. If my 268 ESSAYS ON NAVAL DEFENCE. figures approach, correotaes^, the reoessioa of the power of the gun since the battle of Lissa, as exeniplified in the "Monarch" and " Bellerophon," is in the proportion of 1 to 4'8. The guns are now in point of fact, about five times as weak as they were five years ago. This seems to me a very startling conclusion to arrive at, and one which lies at the root of all construction and armament. It is not as though it were certain the gun must meet the gun, and therefore the recession was com- mon to both sides of the equation, but it is that some other weapon or weapons are making tremendous strides, and are beating the gun in competition. It may mean also that the manner of constructing the carriage — that is the ship — is at the bottom of the recession. In any case, 1 can conceive no more important subject for inquiry than whether my figures and deductions are correct. If they are, I can only express my belief that we are close upon a very extraordinary re-construction of our Navy. 1 Thus, far, then, for the relative place of the gun now, compared with that formerly held by it. Let us look at its actual power in view of the future comparison we shall have to make between it and other weapons. Uafortunately, precise figures are wanting here, and very little attempt has been made to obtain them, as they can alone bs obtained by experiment. The inquiry takes the form of two questions : How many shot will strike the hull of a " Monarch " in a given time in the open sea, and what amount of damage will they do ? and I must own it has struck me as alarmingly suggestive that I cannot get ^ The re-oonstructicn is still going on. Tiiese arguments, in- stiDOtively acting, have prodnoed the subsidiary armament of lighter guns. But the arguments show that this arrangement cannot; be permanent. — Ed. THE ATTACK AND DEFENCE OF FLEETS. 269 an answer oS-hand to either query. Nobody seems to have made the calculation, even with such data as are ob- tainable, and no steps have been taken to improve the data . It is true, I believe, that the materials for determining the number of shot which will strike a given vertical target at a given range, when fired from a steady platform, are ob- tainable, but such a determination must be a very fallacious guide to the results of practice at sea ; nor am I sure that even the materials obtained have been applied to determine the practical question. My figures must be, for these reasons, very imperfect ; but I am obliged to use what I can get. 1 The 12-pounder rifled gnn, at an elevation of 2°, is stated to be capable of placing fourteen shot out of every twenty in a target nine feet square. Speaking roughly, this amounts to saying that two-thirds of the shot fired from a rifled gun are capable of striking a target nine feet square at a distance of 1,000 yards. Actual practice at Shoebury- ness seems to bear out this statement fully ; for on firing twenty rounds from the 12- ton gun, the extreme error of elevation at 1,000 yards was only 13-5 feet, and the mean was only 4'7 feet. In direction, the extreme error was 9-75 feet, and the mean error only 4-4 feet. Out of the whole twenty shot, four only would have missed the " Monarch ;■" two would have fallen short, and two would have gone over. It appears safe to conclude from these figures that the " Monarch " is not liable to receive more than four- fifths of the shot fired at her at 1,000 yards ; and if the chances of being hit vary directly as the distance, at 2,000 yards the " Monarch " js only liable to receive two-fifths 1 1 do not know that any much more reliable figures are even now obtainable, but it may be taken that aoonraoy of fire has considerably improved. — Ed. 270 ESSAYS ON NAVAL DEFENCE. of the shoti tired &t her. 1 This is au admission iu favour of the guns ; for the ohaaoes of being hit diminish in a still greater degree ; but as the error given is entirely due to elevatioa, and the " Monaroh" as a target, is very much longer than she is high, the admission may pass. Under impossible oircumstaiioes, therefore, if a "Monaroh" opened fire on another " Monaroh " at 2,000 yards, she might hit her eight times in ten minutes, but none of these shot would damage the ship in a vital part, and probably would pass through no part of her plating. I use the expression " impossible oiroumstanoes," because to get that result, a steady platform, a fixed objuot, and per- fect coolness and daliburation are required, uot one of which conditions can be secured at sea in action. I have tried to obtain some idea of the deductions neces- sary for each of these conditions ; an unsteady platform, a moving object, and extreme rapidity of fire. But it is not easy. Taking the experiments carried out at Vigo between the " Monarch," " Oaptain," and " Hercules " for what they arc worth, it appears that the three ships fired for five minutes each at a rook distant about 1,000 yards, which was esti- mated to be 600 feet long and sixty feet high, or twice as long, and four times as high, as a ship. " Hercules " fired seventeen " shot, of which ten hit ; " Oaptain " fired eleven shot, and made four hits ;. " Monarch " fired twelve shot, and made nine hits. Speaking roughly, as I am bound to do with rough figures, it would appear that a ship such as the "Monaroh" would, under those circumstances, have been hit three times by the "Hercules," once by the " Oaptain," and say three times by the " Monaroh." ' Ihe real variation must be, at least, as the square of the distanoe, — Bd. THE ATTACK AND DEFiiNCli OF FLEETS. 271 We have seen that '8 of the shot tired would have hit a " Monarch '' at 1,000 yards, the platform being steady ; we now find from the foregoing experiment that '147 of the " Hercules " shot, .09 of the "Captain's" shot, and -187 of the " Monarch's " shot might be expected to hit her at sea in smooth water, when the distance did not materially vary. The question for us is whether these figures may be re- lied on as a guide — whether they fairly represent practice at sea, or either under or over estimate its accuracy. The only other figures at my disposal in order to check the cal- culation are the following. In some recent carefully con- ducted prize firing by one of the ships in the Channel Squadron, it was estimated that at from 800 to 1,200 yards there were only 25 lost shot out of 208 fired. A "lost shot " appears, according to the Admiralty circular, to be one which would miss the " Monarch," passing over her either en ricochet or directly. The firing on this occasion appears to have been exceptionally good, for a triangular target with nine feet sides is represented to have been hit no less than four times. If therefore we are to accept these shot not counted as " lost shot " to be a fair representation of the percentage erf hits in a " Monarch " at sea, we shall find it to be '88 of the shots fired. But we have quoted accurate figures showing that at 1,000 yards — a mean of the distances at which the practice under review was carried on — no more than '8 of the shot fired will strike a "Monarch" when the distance is accurately measured from a fixed and steady platform, and the gun is laid with a nicety impossible afloat. This "88 of hits cannot be therefore a true representation of the practice ; and I think naval men generally will admit that observations of the fall of shot taken from the roast-head and extremes of the ship, are, at their very best 272 ESSAYS OM NAVAL DEFENCE. of an extremely rough character. The tendency of ob- servers in such circumstances is almost always to exagger- ate the accuracy of fire, as I am bound to confess appears to be the case in the details of firing under consideration, But we have seen that the probable number of hits on a target 9 feet square, at about 1,000 yards, is 14 out of 20. A 9-feet square target gives an area of 81 square feet, while an equilateral triangle with 9-feet sides gives an area of 35 square feet in round numbers. Accepting the assumption that the fall of shot on a given surface varies as its area — which I think will be true enough for our present Durpose — we should find that -3 of the shot should strike the floating target in the case referred to. But as i only out of 208 struck it, the actual hits were -019 of the shot fired. Now compare the results of these two investigations. According to the record of " lost shot," this ironclad's prac- tice was really better and closer than that obtained from a steady platform at Shoeburyness ; while, measured 'by the percentage of hits on the target, it was very much worse. Looking again at the Vigo practice, the average hits of the three ships upon a " Monarch," at a 1,000 yards, was •141 of the shot fired, in lieu of the '8 of the shot which would have struck had the practice reached its maximum accuracy. If the prize firing practice had been as good as this, '053 of the shot ought to have struck the floating target in lieu of the "019 of the shot which actually did strike it ; in other words, ten hits ought to have been made instead of four. Artillerists may very likely smile at the rudeness of these calculations and surmises. No doubt they are very rude, but I am not conscious of the endeavour to establish a foregone conclusion of their means, and, dealing with THE ATTACK AND DKFENCE OF FLEETS. 273 them as rudely as they require to be dealt with, they appear to me to establish the probability that a very much smaller proportion of hits by shot will be made in action at sea than any of us have hitherto imagined. Is it really then the case that at the moderate range of 1,000 yards, under the most favourable circumstances, a " Monarch " can only expect to hit a sister vessel from twice to fifteen times out of every 100 shot? A.nd if she fires so many as 1,000 rounds of shot, will only from 20 to 150 take effect? This is a question we should not have left so long unanswered, and it ought to be ascertained with certainty without any delay. 1 I, however, cannot stop to ascertain how the fact may be ; I must make a reasonable assumption on the facts I am possessed of, and I take a mean position between the result deduced from the Vigo experiments and those taken from prize firing, and I lay it down that 10 per cent, of the " Monarch's '' shot will strike a " Monarch " in action at 1,000 yards. We have seen that the " Monarch" is, in her vital parts, impenetrable to shot from the 25-ton gun at 1,000 yards when struck fair. Practically, I believe she will be so seldom struck fair, that no part of her plating is vulnerable until within 1,000 yards, and in anything approaching the end-on position I feel bound to extend this invulnerability to within 500 yards of her adversary. However the ques- tion may be argued, it is certain that only a portion of the shot striking the " Monarch " will penetrate, and we cannot suppose this proportion greater than one-half with any cer- tainty. The amount of damage done by the penetration of 5 shot out of 100 fired must be small in any case. I have now tried to answer the one question as to the pro- 1 I do not think it is ascertained yet.^-ED. T 274 ESSAYS ON NAVAL DEFENCE. portion of shot which might hit a " Monarch " at a moan range, and the other as to the damage likely to be done. The next question arises from a combination of the two facts evolved from the argument, and it enquires " How much damage will be effected " upon a ' Monarch ' by another in a given time, say six minutes ? " And here I must endeavour to correct the assumed speed of fire by the same data taken to arrive at the per- centage of hits. At the rock off Vigo the speed of the " Hercules " was 17 shot in five minutes from four guns, being 3-4 shot per minute, or '85 shot per gun per minute. The speed of t'»;e "Captain's" fire was 11 shot in five minutes from four guns, being 2-2 shot per minute, or -55 shot per gun per minute. The speed of the " Monarch's '' firo was 1 2 shot in five minutes, or 2'4 shot per minute, or -6 shot per gun per minute ; the average of the three ships giving "66 shot per minute per gun. The average speed of the prize firing I have used was '7 shot per gun per minute. Wo must take it therefore that this is the maximum speed attain- able under the most favourable circumstances. It amounts to one round from each gun in a minute and forty-two seconds, so that I do not think there need be any fear of adopting the one round per gun in three minutes, which is assumed afloat to be the probable speed of "Monarch's" fire in action, as representing the truth. But for my pur- poses I would rather assume something above the average, and if I allow one round in two minutes, and 10 per cent, of hits, I do not think I place the gun at the range of 1,000 yards in action at all in arrear of its actual place. Our summary of the actual gun-power of the " Monarch," therefore, amounts to this. In six minutes from the opening of her fire on the THE ATTACK AND DEFENCE OF FLEETS. 275 sister ship at 1,000 yards, she will have fired 12 shot, of which one will have hit and another may have glanced, and it remains an even chance whether the single hit will have penetrated the enemy's armour. With this extremely curious conclusion to our investi- gation I shall leave it, and proceed to the newer weapon — the Ram. Samg. If we are to consider the question of the attack by rams with any hope of a good result, we must begin at the beginning. We must endeavour to treat the question from a purely abstract point of view. We must take two ideal ships of equal speed and turning powers, and condemn them to abstain from many methods of defending themselves which both would use in actual warfare. No disturbing causes must enter into our first analysis, but after we have seen how the case stands, when both ships are limited to strict rules in their behaviour, we can ascer- tain the relative values of those methods which would be used in practice, and we can determine which of them deserve the foremost place. While, however, we select two abstract ships for our purpose, we must take care they are not impossible types. The relations of the length to the turning powers must be such as existing types fulfil ; and the speed over arcs must be such as can be realised ; and, as it has been ascertained with regard to existing ships, that at their highest speeds they turn in a circle whose diameter is from four to six times their length, we may take a circle whose diameter is five times the length of our ships as a safe piece of data whereon to found our investigation. The two ships in diagram 1, therefore, are supposed to travel when their helms are hard over, on the arc of a circle T 2 276 ESSAYS ON NAVAL DEFENCE. whose radius is two and a half times their length. We must suppose them for the present unable to reduce their speed, and consequently unable to travel on a curve with a smaller radius ;l but we allow them to do anything they wish with their helms ; and we are to suppose each equally anxious to ram his neighbour and to avoid being himself rammed. For convenience we shall assume the speed of each ship to be 9 knots, and their length to be 100 yards, or 300 feet. The length of each ship in time, that is, the time it will take each ship to pass over her own length with helm amidships, will be 20 seconds ; 10 seconds will therefore represent half each ship's length in time. It must be now borne in mind that the fact of putting the helm over reduces the speed over the arc in a degree proportional to the amount of helm given. The "Beller- ophon," for example, when going 12 knots with helm amidships, reduces her speed to 7'8 knots over her arc ; and when going five knots with helm amidships, she reduces her speed to 3 '6 knots over her arc. This peculiarity in the action of the helm deserves more con- sideration than there is now time to give. It is, however, enough for my purposes to state that the fact is so, and that it will affect the question of ramming in the manner to be presently seen. Closer scrutiny of the phenomenon will be found in my former paper on " Modern Naval Tactics." If now we take two ideal ships under these conditions, represented in diagram 1 as a? and y, we shall observe that ' Thig smaller radius hardly exists for ships with steam steering gear. It was due to the smaller stretching of the tiller ropes and the greater power over the helm by the man at the wheel. But twin screws much increase manoeuvring power for ramming and avoiding the ram. — Ed. PLATE VIII. D J agratn I Fii- 3. e Diagram II Diagram . ni "h^ -Si To face page ^77. THE ATTACK AND DEFENCE OF FLEETS. 277 SO far as x is concerned, her object is to obtain the position given in Pig. 1 as regards y, and to avoid that given in Fig. 2. y, on the other hand, wishes the opposite. She desires to obtain the position given to her in Fig. 2, and to avoid that given in Fig. 1. What is the difference in these two positions ? What constitutes the badness of y's position in Fig. 1, and of ce's position in Fig. 2 ? In both cases these ships are 50 yards too far ahead in space ; and ten seconds too far ahead in time. What on the other hand constitutes the goodness of x's position in Fig. 1, and of y'a position in Fig. 2 ? The ships are in both cases 50 yards behind in space, and 10 seconds behind in point of time. It is clear also that if x were anything between her whole length and half her length in space; und between 20 and 10 seconds in time behind the position given to her in Fig. 1, she would still strike y a fair ramming blow, for y would not in that time or space be so far ahead as to let x pass astern of her. Again, by as much as x is less than ten seconds in time, or half her length in space, before her position in Fig. 1, by just so much does she run the risk of finding herself in the position given to her in Fig. 2. x'b object is therefore to be between 50 and 100 yards behind in point of space, and between 10 and 20 seconds behind in point of time. Her blow will be just as good if delivered abaft her adversary's beam, as it would be when delivered before it, and if she runs the risk of being too late, she only becomes liable to miss her blow, and does not leave herself open to attack ; whereas, if she runs the risk of being too early, she not only misses her blow, but lays herself open to destruction. Even at this early stage of the enquiry, therefore, it is not unimportant to note that if " excess of speed " be capable of substitution for 278 ESSAYS ON NAVAL DEFENCE. " being too early," and " lack of speed " for " being too late," a ram is not advantaged by the former in the sup- posed case. The ship x in Fig. 1, and the ship y in Pig. 2, hati gained her object and her complete victory. But before she could have got to that stage, there must have been a time when neither had any advantage over the other. They must have once been outside ramming distance, and free from attack, and therefore on an equality. And they may have entered upon the ramming distance on an equality, which had been converted into an inequality by the superior skill of .r in Pig. 1, and of y in Fig. 2. But they may have come into ramming distance on an in- equality, and the conqueror may have had it all Iiis own way from the first. Let us, therefore, examine what constitutes ramming distance first,, and then what consti- tutes the inequality. Every ship when advancing at speed carries on each side of her two circles of considerable size, within the cir- cumference of which no power on earth can place her. These circles will vary according to the speed at which the ship travels, and according to the power she possesses of stopping herself quickly. Another ship which is any- where inside this circle cannot be rammed so long as she remains there. It is clear from this that it must be from some point within this circle that a ship will find herself able to deliver a blow safe to herself and damaging to her adversary. Outside this circle neither ship can ever get an advantage over the other, both must always be equally free to move. I therefore assume that a ship is within ramming distance of another whenever she is on, or inside, the arc on which the other turns. And, extending this definition to meet oases where neither ship is within THE ATTACK AND DEFENCE OF FLEETS. 279 the circle of the other, though in close proximity, we may say their ramming distance is twice the radius of the arc described. In diagram 1, Fig. 3, I have represented the ramming distances due to y under the hypothesis we have assumed, and large as these spaces seem, you must re- member they are only the average spaces which existing ships carry about with them when steaming. The mere fact of being within ramming distance of another ship gives no advantage beyond the safety from your opponent's ram. The ship x at p, the centre of i/'s port circle, has no advantage over y, because y is also at the centre of .r's circle. Nor has x at q any advantage ; a; is in precisely the same position as regards y, as y is with respect to X. But suppose X to have come into t/'s circle as in Fig. 4:, and we shall see she has a great advantage. In this case x is inside y's circle, and, therefore, safe herself, while y is outside x's circle, and is, therefore, open to attack. It seems to me that the whole art and mystery of ramming will be found to consist in this endeavoar to get your adversary outside your own circle while you remain inside his. X has a manifest advantage on the face of matters in this figure. She is excluded from receiving a blow, and is not prevented from giving one. Let us therefore enquire more closely as to the exact chances she has of ramming y under the circumstances postulated. In the positions given, x is 40 seconds from the collision point 0, while y is only 25. If therefore both ships pursue their present courses, x will ram y 75 feet from her stern ; y cannot therefore continue her course with safety. Let us suppose she puts her helm hard-a-port, to turn from x along the curve y s. The average time of turning of four ships of the Channel squadron at 12 knots is given as 6 280 ESSAYS ON NAVAL DEFENCE. minutes 2 secondB, and at 5 knots, as 10 minutes 45 seconds. We may therefore assume tbat our ideal sliip y will complete her circle in 8 minutes ; it will consequently take her one minute to turn through four points, which will bring her to a. But x is just 55 seconds from the point a ; and she will, if she goes straight on, be herself rammed by y, 75 feet before her starboard beam. She avoids this mishap by porting her own helm, which has the double efiect of delaying her progress, and enabling her to strike y a fair ramming blow before she reaches the point a; y VD. short cannot escape either under steady or port- helm. If y puts her helm hard-a-starboard, she has a better chance, for x is only 25 seconds from the point h, while' y is a minute from it, and consequently y may get inside x'a circle and be safe, before x is aware of it. But x can only lose his chance from want of skill. It is his sole business - to keep inside y's circle, whatever happens, and he should put his helm hard-a-port immediately, and turn along the arc X q^. li y now persists in keeping his helm over, x has only to reverse his own at the right moment, and give y a fair ramming blow amidships. In the case before us, therefore, y does not appear to be able to avoid the stroke of a;'s ram by any employment of her helm. If 9 knots is her utmost speed, she cannot now increase it, so escape by that means is cut aS. If she had it in her power to reduce her speed instantaneously to 5'6 knots, she would only reach the point o at the same time, and therefore on an equality with x. It may be assumed that a ship of any size could not reduce her speed by so much in so short a time ; but let me remark, parenthet- ically, of the difficulty I am placed in for want of data on this subject. It will be clear to you all, that next to a THE ATTACK AND DEFENCE OF FLEETS. 281 knowledge of the turning powers of ships, and the theory which may be found to lie at the bottom of it, there is no more important consideration for any one proposing to attack by the ram, than the time and space within which the ram can stop herself, or reduce her speed to a given figure. Yet I am not aware that the experiment has been tried with any ship, or that it has beeu so much as noticed as a requirement.! HoweTer the actual case may be, we may reasonably assume that y cannot reduce her speed so as to be 20 seconds later than x in arriving at the point o. But she may hope to escape by reducing her speed, and putting her helm hard-a-port. Let us suppose that she can and does reduce her speed instantaneously to 5 knots. What is the result ? The difference in the diameters of the circles of four ships of the Channel squadron at 12 knots and at 5 knots, was only 53 yards. The radius of y's arc at 5 knots cannot therefore be assumed to differ from that at 9 knots, by more than a quarter of a ship's length. Hence the arc y now describes will not cross a^'s path more than 10 or 12 yards to the right of the point a. This is not enough to save her, in fact it bring x's blow still nearer the midship point. But besides making this trifling alteration m the matter of space, y's reduction of speed has made a more considerable one in the matter of time; y will take 20 seconds longer to cross x's path under port-helm at the reduced speed than she did under the full speed of 9 knots. We deduce this fact from the knowledge we have that the average time of four ships of the Channel squadron in com- 1 I believe I myself had made almost the only attempt to get accurate data on this head until 1889, when the present hydro, graher moved in the matter. — Ed, 282 ESSAYS ON NAVAL DEFENCE. plefcing their circles at 5 ktiots, was 10 minutes 45 seconds, in lieu of tlie 8 minutes calculated as the time of turning at 9 knots. Supposing cc, therefore, to allow herself to fall into the trap, and to proceed along the line x a at speed, she would cross 2/'s path entirely, just before the latter reached the point a. But before she got so far as this, she would have surrendered her advantage over y, in having got outside her circle, and allowed y to get inside hers. Admitting she was unskilful enough to do this, y can only deliver a 5-knot blow upon x, and has surrendered so much of her power by reducing her speed to that figure. But we cannot suppose x would lightly surrender her advantage when she can keep it by the use of a little port helm. In this case it is evident that y'a delay along the curve y a, leaves it open to x to give her a perfectly fair ramming blow almost at her leisure. There is still one last course open to y, namely, to reduce speed with the helm h ard-a-star board ; and this seems to me the most judicious thing she can do. She will now take I minute and 20 seconds to reach a point ahead of .1?, somewhat nearer to her than the point b, which latter is, by our hypothesis, 25 seconds only from x. If x {herefore delays an instant in putting her helm hard-a-port, her circle will pass ahead of y, and she may find herself open to the blow of y's ram at the reduced speed, or, if she saves herself from the danger, there may not be room for her to give y a stem blow. The two ships will, in short, most probably rub broadside to broadside in passing, with- out material damage to either. But it must not be supposed because y does the Cest thing possible under the circumstances that she. gains any advantage over x ; she may recover the position of equality THE ATTACK AND DEFENCE OF FLEETS. 283 she originally lost, if ce is unskilful enough to permit it, but that is all which is left open to her, and in any case her reduction of speed is a surrender of her manoeuvring power directly in favour of .r's proceedings. It is open to ,r to reduce her speed at the same time y reduces hers, in which ease she retains all her former advantages, except that her blow, if delivered, will not be so heavy. I have not time on the present occasion to pursue the enquiry as to whether the position I have assigned to my two ships in Pig. 4, is really the worst for y and the best for a; ; it is sufficient for my purpose to show that it is a position extremely desirable for ce to seek and for y to avoid, and that if y unhappily allows herself to get into it her fate is very nearly sealed. I think, however, the general principle may be assumed that the grand object of an attack and defence by rams must be to keep your adversary outside your circle, and at the same time to keep within his. The next point we have to consider is how should x approach y so as to get into the desirable position ? There is a very prevalent idea afloat that the end-on position is the one proper to be assumed. It was one held by myself also, I may say, until I undertook the prepara- tion of this paper, and I can, therefore, the more freely deal with it, and, if necessary, condemn it. Let us suppose, then, that x and y, meeting in the open sea, and being each imbued with the necessity of keeping the end-on position, steer for each other. They must either give up their end-on theory, or they will at length reach the position given in Kg. 5. They are now within ramming distance, on an equality certainly, but each pre- cluded from using the weapon that each is endeavouring to use, unless they are willing to try which is the hardest 284 ESSAYS ON NAVAL DEFENCE. at the point o, an extremely improbable conjecture. But observe the position they have placed themselves in. They must either stop where they are, and give up all hopes of ramming, or they must dash at each other on an equality, or one of them must try some other plan. What plan is open to her, let us say, to y ? She may turn along the curve y p, or along the curve y q, or along any curve between those. Let us suppose she puts her helm hard-a-port ; in thirty seconds the ships will be in the position given at Fig. 6. In this position y has turned through two points, and is just about surrendering her equality, and allowing x to come within her circle, while she herself is outside x's circle. The danger of her manoeuvre is not so great as it at first appears, but there is no doubt that she has sur- rendered all hopes of using her ram upon x. That she is not actually in danger may be noted from considering that she is thirty seconds from the point d, while X is one minute from it ; y, therefore, has a good chance of dragging her whole length across x'a arc before she reaches the point d. But y has a still better chance of escape if she now rights her helm, for she is only twenty seconds from the point 6, while x is fifty-three seconds from it. But, whatever her chances of escape may be, she has no chance of attack, and, as it may be assumed that any movement either ship might make from the position given in Fig. 5, would result in a position similar to that in Fig. 6, we must take it that there is a fundamental error in the end-on approach of two ships intending to ram. It may be true thafi the end-on position is proper to avoid being rammed when there is no intention of ramming, but this is not the case wo are now called on to THE ATTACK AND DEFENCE OF FLEETS. 285 investigate, and is assuredly not the case supposed by those who have abrogated the flank method of evolution in favour of the oblique. Let it be noted here that though from a consideration of Figs. 5 and 6, there is great objection to the end-on position when within rwmming distance, there is no objec- tion to it beyond ramming distances ; but then, on the other hand, neither is there any objection to the broadside posi- tion, or, in short, to any other position. The question of the nature of an evolution does not seem, therefore, to be affected at all by the proposal to attack by rams, although the nature of a formation may be. The only movement undertaken when within ramming distance would be the final sweep to ram, or avoid being rammed. Any prepara- tion for this final sw#ep must be made beyond ramming distance, where the ships are free to use what means they please. As this end -on approach is not to be sought for in a ramming attaci, because of its liability to result in a posi- tion given at Pig. 5, the question is how should two ships approach each other who are equally ready for the combat ? The answer is to be found by considering that the only difierence between x and y in Fig. 4, is that x is half a ship's length further from the collision point o than y is. We must expect the struggle to be to keep the courses at right angles to each other, but to be rather behind in reaching the point where they cross. The two ships may, therefore, steer for each other in the first instance, but before they close they will each mutually assist to place their courses at right angles, and to keep them so ; or one of them by superior skill will approach on some- thing near the end-on position until he can by a sudden and unexpected movement bring himself within ramming 286 ESSAYS ON NAVAL DEFENCE. distance, at right angles to the other's course, and inside his circle at the same time. In the first case, each ship would immediately bring the other, four points on the bow, and so gradually approach each other, and the most skilful of the two would by such means as were open to him take care to be a little behind at the last moment, ultimately taking the place of x in Fig. 4. In the other case the ships would steer directly for each other at first, and might be expscted to assume parallel courses, at such distance as would be determined by the most skilful of the two, and we should thus ultimately find them in a position similar to that given in Fig, 7. Here x has determined to get into the position ^j, by a turn of eight points to port, at the* same time as y, by pursuing his course, arrives at the point g. x is two minutes from the point p, consequently his turn must be made when y is two minutes, or 600 yards, from q. The distance between the paths of x and y must be equal to the diameter of the circles, or else x cannot come into posi- tion at p. X will consequently commence proceedings when y is at the great distance of 1,200 yards from him, and nearly 2J points on her bow. If all goes well, and y permits herself to fall into the trap, X will certainly gain her wishes and destroy or damage y, being herself in perfect safety; and there is certainly this to be said for such a method of attack, namely, that y will only observe the bearing of x to alter a couple of points, will have little guide as to her intentions, and only two minutes in which to make up her mind. Yet, of course, any movement of y'a helm either way, before she reaches the point q, will overthrow lo'a calculations, and make it necessary to try some other plan, y, however THK ATTACK AND DEKENGE OF FLEETS. 287 may divine x'a idea, and may, by slight alterations of course to port, bring herself within x's circle when she gets abreast of the point q. She will thus turn the tables upon x, which is just the risk she runs, and which may arise from- a mis- calculation of the distance or speed of y. The point to notice is, that this method of approach on parallel courses, a diameter apart, is one which may be adopted by two ships equally anxious to try their skill against each other in ramming. We should notice that x, in adopting the foregoing methoa of approach, proposes to obtain her object by a double movement : one into the safety position inside y'» circle, and the other the delivery from thence of her final blow, and she leaves it in her power to abandon her intention at any moment prior to reaching the point p. Having once reached it, she places herself in the power of y if she turns out to be a certain distance to the left of q. But a; may also decide to deliver her attack from the out- side of y's circle, and only to come within it at the moment of collision. In this case, she will approach on a course parallel to that of y, but only one radius distant from it, as shown in Fig. 8. Here x must put her helm over when 2/ is 1| points on the bow, and about 850 yards off, and she will arrive at the point q a little after y reaches it, sup- posing the latter to steer a straight course. But it is most unlikely that y will put herself into the wished-for posi- tion. The change of helm by .v, will be very apparent to y, and her design almost equally so, and the smallest pos- sible movement of helm may not only baulk it, but place .r in a very difficult position, for it is possible that y might meet a; within ramming distance, while the latter had her helm hard over, and the former had hers amidships. In this case, x would clearly have only half the manoeuvring 288 ESSAYS ON NAVAL DEFENCE. power of y, and might suffer for it. x in short cannot make a re-calcnlation of her position and prospects when within ramming distance, should she attack in the method given in Fig. 8, while she can well do so should she attack as in Fig. 7, and should she choose the first method of approach, bringing her enemy rather less than four points on her bow, and forcing her to Teeep so, she is perpetually re-calcu- lating her chances and position. We have now discussed roughly the principles of an attack by rams from ahead, when the ships have equal speed and turning powers, and I think it is apparent that the 4-point method of approach is the one we should choose under the circumstances. We may now look into the advantage, if any, which x would gain from the possession of superior speed. We may in doing so, leave out of the question those advantages which speed gives in bringing the enemy to action against his will, for we are supposing both ships equalUy anxious to meet. We need not, therefore, trouble ourselves except with the changes which greater speed for x would intro- duce in her position in Figs. 4, 7, and 8. In Fig. 4, if x had a speed of 12 knots in lieu of 9, she would, by pursuing a straight course, strike y nearly amidships at the point o, instead of well abaft her beam, she might therefore begin her attack from a position farther astern, and therefore safer from a miscalculation of the size of j/'s circle. This would be her advantage also in case y put his helm a-port. But on the other hand, if she found herself at the position given, with this extra speed upon her, she may be obliged to forego her attempted attack in order to save herself, for if y puts his helm hard-a-starboard, x is advancing so rapidly that she can hardly avoid allowing y to get inside her circle, and the moment that happens, she is either at THE ATTACK AND DEFENCE OF FLEETS. 289 j^'s mercy, or she must escape under starboard helm and her superior speed. In Figs. 7 and 8, the advantage of superior speed is that x may allow y to approach more closely, and therefore under a better estimate of her distance before she turns : there is no other advantage known to me. Eeverting then to Pig. 4, if a; with greater speed than y means to attack her with the same advantages as x is now seen to possess in the diagram, she must either be further from the point o herself, or y must be nearer to it ; but the skill required at the low speed and at the high speed is equal, and the dangers of being rammed instead of ramming, are possibly a little increased. I do not look upon great speed consequently as very important for a ram. But if the question is not one of permanent speed, but of the power of incressing or reducing the speed of the ships rapidly, then there can be no question of the advantage. The increased speed will save the ship from being herself rammed, and the power of reducing it will enable her to ram effectively, and hence we may assume that a very heavy ship is an ineflBcient ram, for she cannot have the same powers of varying her speed as a much lighter one would have. But now, suppose x with no advantage in speed, is half the length of y with the same proportionate turning powers, and observe the conditions under which she will meet y in Fig. 9. It may be seen at a glance that she has y abso- lutely in her power, for she has all the advantages she before possessed, besides the infinite advantage of manoeuvr- ing freely within y'a circle, and being able to frustrate in the most perfect manner any attempt of y's to escape under starboard helm, which we before saw was really her only chance. 290 ESSAYS ON NAVAL DEFENCE. Then again, look at Figs. 7 and 8 as to her facilities for attack under the new conditions. In Fig. 7, if nc had mis- calculated her distance and found that y would be too far ahead to be rammed from the point p, her stroke would have been altogether lost, but under the new conditions she might commence on the curve x p, but end on the curve X t, thereby having it in her power to move the point p to suit the movements of y. While under the old conditions, the boundary of her possible movement under starboard and port helm was x p q, it is now enlarged to xts. So in Fig. 8, x may commence on the curve x p, but has a reserve of manoeuvring power as far as x r. If it be said that ij by increased speed can make up for iw's increased turning powers, I think we must deny it, unless y surrenders all idea of ramming, or even of allow- ing her adversary to come within ramming distance. If she allows x to close her, and to get into the position given at Fig. 9 — which she is very likely to do — her speed will hardly save her; for allow her 12 knots to x'b 9 in Fig. 9, and she cannot escape under starboard helm, she has not a foot to spare under port helm, and she has not a ship's length to spare under steady helm ; and it is not to be supposed that x in the confidence of her manoeuvring power will not provide against this chance by keeping much closer to the point o. There is, however, a method of attack for which superior speed is necessary to success, and that is the attack from the rear, either directly or by an advance past the adversary, and a turn upon her. Of the direct attack I need not speak much ; it would doubtless be possible for a ship with superior speed to chase and to ram a ship of inferior speed, which declined to face her. But the blow so given would be a light one, as its velocity would only THE ATTACK AND DEFENCE OF FLEETS. 291 be the difEerenoe between the two speeds, and it would undoubtedly be long in coming. The indirect attack is made by the ship with superior speed coming up from the rear on a course parallel to her adversary's, and one radius distant, then drawing sufficiently ahead to strike her at right angles by a turn of 8 points. This case is ably treated by Admiral Boutakov, and I agree with the con- clusion he draws, that the adversary need never allow her- self to be so rammed ; she can see the opponent gaining on her, and must know what the result will be ; she can then either turn from her or towards her in perfect safety, and the result will ultimately be the direct attack I hare noticed. Long as we have dwelt upon this question of the ram as a weapon, it must be apparent to all that I have only touched the outskirts of the question, and until Naval Officers will turn their intelligence fully upon it, on the outskirts of the question we shall remain. We have, however, I think, shown a probability that the following conclusions approach the truth : — 1. The end-on position must never be taken up by a ram until the moment her spur strikes the object. 2. Extreme speed is not so necessary for a ram as extreme powers of turning. 3. Great length and weight are an inconvenience to a ram. It may be added that they are not necessary for an efEective blow. The work done upon a ship by the 4001b. shot from the 18-ton gun is under 5000 foot-tons. The work done by the stem of a vessel weighing 1,000 tons, propelled at 10 knots, is equal on impact to 4,270 foot- tons, and the work is done below the armour. 4. So far from ramming being a difficult or impossible task, it is a thing which can be accomplished by superior skill with vessels otherwise equal. But a ram whose n 2 292 ESSAYS ON NAVAL DEFENCE. turning powers are much greater than her adversary's may attack her with every confidence of success. This seems the place to advert to the ordnance proper to be carried by a ram. I must confess myself doubtful about the end-on fire — a result I did not at all expect to arrive at when I planned the paper. I had in my previous papers laid it down that I would in no case use my guns on approaching to ram, but that I should be glad to see my adversary use his, because my movements would be disguised thereby, and I observe a great French authority, Admiral Jurien de la Gravifere, has recently advocated the same view. If this is so, when is a ram to use her artillery ? The answer seems to be, when she has missed her blow, and is passing her adversary broadside to broadside. Except at that moment, " The poor advantage," as Admiral de la Gravifere says, " to be gained by a discharge rendered uncertain by the rapidity with which the distance varies, cannot com- pensate for the cloud of smoke which would envelope the ship at the all-importeint moment, when her safety depends on the precision with which she is handled." It may be argued that this is true enough of the case when within ramming distance, but that ships should be armed for end-on fire before coming within it. The answer to this is, that we have seen how a ship may really commence her ramming manoeuvre at the distance of 1,200 yards if she adopts nearly the end-on position, and that if she approaches on a i-point bearing, a very slight alteration of course, will bring her broadside guns to her. I thus conclude the rough examination of the ram question as applied to single ships, and as separated from artillery fire and the torpedo. I must now pass to the latter and newer weapon. THE ATTACK AND DEFENCE OF FLEETS. 293 Torpedoes. 1 In tb.e very admirable paper given to us by Captain Dawson, on OfEensive Torpedo Warfare, he expressed his oonviction that we were neglecting a very powerful and valuable weapon in the outrigger torpedo, which he believed applicable to fleets. Unfortunately experiments on the question are wanting, and it would not be possible, in the absence of them, to make the outrigger torpedo a basis of attack and defence. This mtich may be said for them, however, that if they succeed at all, they will cer- tainly succeed in an attack from the rear. I have shown that a vessel with superior speed may strike another about the stern with an inefficient blow, equal to the difference between their speeds. These are the condi- tions under which the outrigger torpedo would supply the deficiency. The vessel using it consequently wants speed, bat need not be a ram. Captain Dawson thinks they might be employed in outriggers at right angles to the keel, and be so used by a ram which had missed her blow and was passing broadside to broadside of her object. Under such circumstances the torpedo would compete with the broadside gun, and I am rather inclined to think the latter to be the more effective weapon. The Harvey torpedo seems to me a weapon by itself, and not an auxiliary, like the outrigger torpedo. I understand that Captain Harvey deprecates its use in ordinary ships, and proposes special ships to employ no other weapons. To me, however, it seams a weapon well adapted as a defence against rams in large and long ships. If the ' This section is only useful ai showing; what naval opinion was at the date of publication.

Her tactics would be, in the event of missing her blow, to pass close under the stern of y, trusting to run over the torpedo line. The danger, however, would be great, for the line might easily be fouled, and then y's progress might draw it under no's, bottom and explode it there. The Harvey torpedo vessel does not require anything but great speed, but this she must have to be eflScient. The tactics she pursues are very much simpler than those of the ram, for she does not want to be in a particular place at a particular time; all she requires is to pass her ad- versary within about 200 yards on any course, and her mission is fulfilled if f3he succeeds in doing so. In the attack by such a vessel on another of her class, skill appears useless as against speed, and it would seem the slowest ship must be destroyed. The object would probably be an endeavour to cross each other's bows, and the fastest ships must ultimately do this. These few remarks are all which seem to me necessary on the question of torpedoes as applied to the attack and defence of single ships. They are weapons destined to play an enormous part in the operations of future naval war, and if hereafter I continue this subject, their imme- diate part in fluets must be examined, but as regards the chief of them, the Harvey torpedo, I don't see how it can be discussed by itself. A Harvey torpedo ship meeting another in the 'open sea, and knowing her to be one, cannot run down upon her and trust to chance as to which torpedo takes effect first. She ma,y certainly approach as a ram (x) would in Figs. 7 and 8, with the intention of crossing y's THE ATTACK AND DEFENCE OF FLEETS. 295 bows at some distance ; yet y can. never be supposed foolish enough to run such a risk. If she thinks she has superior speed, she will carefully abstain from all close quarters except with her head the same way as her enemy, and with helm amidships. It is not as in ramming, where a distance of 50 yards or so makes all the difference be- tween victory and defeat. It is more a question of superior speed, and a knowledge that the superior speed, properly used, must destroy the adversary by torpedo, just as su- perior turning powers must destroy her by ramming. The effort of two torpedo ships, it seems to me, will be confined to ascertaining which has superior speed, and the strong probability is that in the ascertainment of that fact one of the two will perish, The Attack and Defence of Single Ships. Only now, after this separate treatment of the gun, the ram, and the torpedo, are we in a condition to combine them, and to observe the effect under such circumstances. But before proceeding to such combination, it appears to be the proper moment to advert to foreign naval opinion on the status of the weapons. I must leave the torpedo out of this account, for I know not the opinion entertained about it abroad. The rise of the ram in foreign estimation is one of the most remarkable features of the age. Dating from the first utterances of our gallant Admiral of the Fleet, Sir George Sartorius, the ram has carried all navies by storm, and, so far as I can gather, except in Russia, without en- quiry. When I read my paper on Modern Naval Tactics here, in the year 1865, and acknowledged myself a com- plete convert to Sir George Sartorius's views, English naval opinion was incredulous. Admiral Boutakov had 296 ESSAYS ON NAVAL DEFENCE. written ably on naval tactics, but had nowhere expressed a conviction that the ram governed the tactics of the future, although au enquirer so acute and unprejudiced could not avoid allasion to its growing importance. In France, a system of tactics based wholly on the supposed unrivalled empire of the gun existed, and there was only the faintest glimmer of an idea that the old line of battle was about to fall from its high estate. Now look at the change. Admiral Boutakov has worked at the ram question to an extent unattempted by us ; and Russia has drawn up her scheme of naval evolutions on the avowed principle that the ram is the only weapon of value against a fleet. France has pushed her old system of evolutions into the back ground, in the firm belief that the ram, and the ram only, need be feared at sea. The ramming experiments tried by the Russians under Admiral Boutakov, are altogether too interesting to be left without a passing notice. He took two gunboats of 200 tons each, and fitted them up as harmless rams. A sort of gabion, or extra large fascine was fitted to the stems of these craft, and a belt of fascine work ran all round their gunwales. Captains of two of the ships present were placed in respective command of the rams ; they were turned broadside to broadside, head and stern, and started to damage each other as much as they could. Cross-bear- inga of the two rams were constantly taken during the continuance of the struggle, and the corresponding tracks mapped out. Two of these encounters have been repro- duced in Diagram II, where the dotted line represents the track of the ram " Priliv," commanded first by Captain Kolon, and secondly by Captain Vogak. It was a rule in these encounters that a Captain lost his command when he was rammed, and consequently some Captains of greater THE ATTACK AND DEFENCE OF FLEETS. 297 skill slew several foes before they lost their own command. The Straggle represented in the npper fignre lasted 16 minutes, and the track of the victorious ram, the " Goul," commanded by Captain Ivanov, is shown in black. Ivanov was again victorious in the struggle shown below, but not till 30 minutes had elapsed. Twenty-one of these en- counters rtre given in the pages of the " Revue Maritime," and the shortest time in which the ramming was effected was 5 minutes ; the longest being 50 minutes ; the average being just 20 minutes. No doubt the battle of Lissa has had much to say to the advance of the ram question, but in England we did not lay that lesson to heart as Russia and France have done. The confirmation of my belief in the ram which Lissa gave, and which I very strongly put forward, carried only a small section of the service with me. I was still met as before, by the remark that it was very diflBcult to ram another ship, and I believe that even now only a section of the English. Navy is disposed to forsake the trust in our guns and to put it in our stems. If I am not completely in error on the question, I hope that what I have already said to- night will lead my brother officers to look into the matter more closely than they have yet done, and with minds so much morQ capable than mine, to ascertain what the truth miy be and not to rest satisfied with mere vague phrases and vaguer thoughts. 1 Let me now briefly endeavour to picture what the nature of a duel in the open sea would be between two " Monarchs," each equally ready for the fray, but one of them determining to use her guns and depending upon ^ It will be uuderstoo I that the rise of the locomotive torpedo, by makiog the approach to ram more dingerous, hai pushed than weipon back, and the gun forward. — Ed. 298 ESSAYS ON NAVAL DEFENCE. them, and the other looking at her guns as a secondary weapon. To keep up our terminology, I shall call x the ramming ship and ■;/ the one depending on her guns, it- would, on first sighting her adversary, bring her about 4 points on the bow and manceuvre so as to keep her there, while she advanced at speed, y might be expected to steer direct for her enemy, trying perhaps, an occasional long shot and swerving slightly to do it. At about 2,000 yards distance, y would find it convenient, if not forced to do it before, to bring a? about 4-points on her bow so as to keep a steady fire upon her, which we must suppose from that moment to commence. They are each now, in Kg. I, Diagram III, 1,400 yards from the point at which their courses cross; and if they were going 10 knots, — which ,r at least will be certainly doing, as she knows her greatest safety from shot lies in the rapid alteration of elevation of y's guns, — if they were each going 10 knots, they are only 4 minutes 12 seconds from collision. What damage can y do with his shot in that time ? She may fire two shots from each gun, or eight in all, of which we have seen none would hit if the ship was steady at 1,000 yards; and the distances at which these shot are fired varies from 2,000 yards to nothing. The gauntlet which .r runs is a bagatelle, no ship need fear it, and if y has laid herself open, and permits a; to get into ramming distance, as in Pig. 4, diagram I, it is all over with her, unless she has reserved her fire for the supreme moment. But we may be quite certain that no fire will be reserved. She will have exhausted all her efforts in combined accuracy and rapidity, and x will only run the chance at close quarters of receiving a stray shot badly aimed, as it is sure to be at such a time. If x has passed through 4 shots, a minute before collision, she is safe from any further fire. THE ATTACK AND DEFENCE OF FLEETS. 299 But suppose that y is wise enough to perceive his danger, and to turn towards x, along the curve y r, Pig. 2 ; X cannot now ram conveniently, he therefore takes the step he had previously prepared for, and brings his guns into play. His method is to sweep round upon the large circle x q, with his guns trained right abeam on the star- board side. In 30 seconds he discharges them full into the plates of y at pistol range, and passes away unharmed to prepare a renewed encounter. I cannot pass a very probable feature of this kind in a naval duel, without remarking on the advantage y would have were she armed as a broadside ship. If y discharges her port broadside at x, two minutes must elapse before she does it again ; more than two minutes must elapse before she can transfer her fire to the opposite broadside; con- sequently X has it all her own way in passing starboard side to starboard side. If y, however, had a second set of guns ready on her starboard side, x might take less from her manoeuvre. Time does not permit me to dwell longer on a part of my subject which will bear any amount of the closest study. I have indicated what seemed to me the absolute values of the gun and the ram, and I have endeavoured, by bringing them into opposition in a fight between two ships, which I imagine to be a representative combat of its kind, to get at their relative values. I might infinitely vary the circum- stances of approach and subsequent conduct, but so long as X acts on the assumed superiority of his ram, and y on the assumed superiority of his guns, their combat must par- take of the nature of that I have sketched out. x will again and again make his effort to ram, and will only take to his guns after each failure ; y will persist in believing he is damaging his opponent, which in my view he will not 300 ESSAYS ON NAVAL DEFKNOE. do, aad x'a failures to rum will not prevent him damaging his opponent effectually by his broadside guns. There are some points to be noticed in the details of such a combat, as 1 hare sketched, cc cannot be put to a dis- advantage by the direction of the wind, whereas, if y is unhappy enough to engage to windward, the smoke from his own guns will hide as from him, and will, while it interferes with his own fire, effectually shield the oper- ations of X from view, y, however, is not at all hidden from X, who observes her every movement at his leisure. The temptation to go at slow speed so as to make better shooting, is very great ; yet nothing could be more danger- ous than to be caught at slow speed within ramming dis- tance by a ram. It may be thought that it is improbable that all combats should take the form I have sketched out, but I think it is possible, that if one ship determines to keep her opponent on a 4-point bearing, she compels her to do the same, as being the only way of approaching, so that the ram is still the master, even in directing the method of his enemy's approach. Wherever the Harvey torpedo makes its appearance, whether in company with guns and rams, or by itself, it is still speed which must carry the day. Whatever one ship may think of his guns or his ram, he must try his speed and his torpedo, if the other chooses to adopt that mode of attack, y could not, as in Fig. 2, diagram III, if X was towing a torpedo, turn towards him and allow him to cross his bows ; he must turn away from him, and trust to his own torpedo to keep x'a ram clear of him. Hence they come to parallel courses, and artillery fire, broadside to broadside. The struggle will immediately be, which is to head the other, and whichever can Mucceed, THE ATTACK AND DEFENCE OF FLEET3. 301 must be victorious. The tendency of the Harvey torpedo seems thus to be, to bring the gun forward again, as the tendency of the ram has been to push it back* While this struggle for precedence continues between two torpedo vessels at short range, much damage must be done by artillery ; and if the. speed of the ships is nearly equal, the combat might be decided by a broadside action of the old type, except that it is carried on at high speed. Here then, I close, my examination of the bases on which the attack, and defence of modern fleets must rest, and no one can be more conscious than I of its vagueness and imperfection ; but I hope it will be admitted, that I could not proceed to carry out the examination set forth in my title, until 1 had come to some conclusions, such as I have put forward : and, in any case, I trust to have shown, that with proper experiments and deductions therefrom, the relative importance of the weapons we are dealing with, and their judiciou,s employment, first, in single ships, and finally, in fleets, may be fairly estimated. I must not quit the subject without adverting to those principles of construction and armament, which the matters we have been discussing, appear to recommend. End-on fire appears less a desideratum than I at first supposed it would turn out. For a ram, it seems quite unnecessary, as the latter seems to combine much more satisfactorily with the old-fashioned broad-side gun. The ram, pure and simple, is strongly advocated as a weapon, by Sir George Sartorins ; and I must own that, it seems to me, a gunless ram of equal speed with the " Mon- arch," but about one-fifth her size, would meet her on equal terms in the open sea.l ^ Some part of this idea seems to have been at work in producing the Polyphenms.—'EJi. 302 ESSAYS ON NAVAL DEFENCE. If such a ram were to attack, a larger ship could beat defend herself by a large number of light shell guns. Such might be easily employed in a broadside ship, in addition to her plate-piercing armament, but could not be employed in the " Monarch." 1 If, however, it is found that a ram of 1,000 tons can be so plated as to resist all but the heaviest shot when striking at an angle of 45°, then it appears to me, there is no help for the larger and more un- wieldy mass such as the "Monarch," except the towing torpedo. If light swift torpedo vessels are designed, a heavier and slower ship must meet their attacks by multiplying the numbers of lighter guns carried. On the whole, it does appear to me a matter for very serious consideration, whether this straggle after gans which will pierce the heaviest plates at long range, has not overshot itself — whether the point has not already been passed at which the redaction in the number of shot, which can be fired per minute, is compensated by the increased power of the gun. But while it is impossible to dogmatise on these various points, am I wrong in thinking that the service and the country, should seriously undertake to determine the relative values of the gun, the ram, and the torpedo, and not to rest content for one moment longer in an atmosphere of misty ideas on the question ? 1 This idea has received its development in the secondary arma- ment of battle-ships.— Ed. 303 CHAPTER VIII. - THE ATTACK AND DEFENOB OF FLEETS. 1 MuoH of the neglect under which my subject undoubtedly lies, may proceed from an idea which impressed me very strongly at one time, namely, that the attack or defence of a modern fleet cannot be profitably stadied prior to the ex- perience of many actual combats. It seems at first sight probable that no such thing as rale or law can be evolved except from the facts of experiment in war. It is there- fore readily assam.ed that naval tactics are not yet in a condition to be made a subject of study. This line of thought would be excusable after many failures to discover the hidden law or laws which may exist, but it does not excuse the neglect to seek for them. We have no business to make the assumption in the first place, for it is founded on no data; and, moreover, I trust to have shown in former papers that so far from being the vague con- glomerate of conflicting opinion generally supposed, a very superficial analysis recovers many points of absolute cer- tainty round which theories may safely revolve ; or, at the very least, gives encouragement to persevere. There are, however, two ways of approaching thestady. 1 Written in 1872. 304 ESSAYS ON NAVAL DEFENCE. The first is very easy, very common, and very misleading. The second is slow, troublesome, rare, but may lead us to the very centre of the maze. The first is the empirical or ratioeinative method — the second, the inductive. The first assumes some theory of attack and defence, some pet for- mation, or favourite weapon, and argues to the particulars of a combat founded on these assumptions. The latter assumes nothing at the outset. It establishes particulars by observation and experiment, and then collates, or colli- gates, as it has been called, these particulars, until it weaves them into general harmony. The former method may turn out a truth in the same way as you may throw sixes with dice. The latter method may be leas brilliant, but what it establishes is reliable, and in any case such errors as occur, are capable of detection before the general result comes to be applied in war, for they must be caused either by some mistaken particular, or by some wrong application of particulars which are in themselves true. I need not say which of the two methods has my approval, or on which of them I intend to base my present enquiry. My former paper sufficiently showed. that I was content to make any sacrifice rather than proceed to' generalise hastily. But in applying such particulars as I assumed to be established when I last addressed you, I must ask yon to bear in mind that they are assumptions still, in a greater or less degree. There is not one of the points then adverted to which will not bear — nay, which does -not imperatively demand — rectification by observa- tion and experiment. I deny absolutely that we can form any correct notion of what a future naval action will be from the colligation of circumstances which we do not know absolutely to be facts. At the same time I hold in THE ATTACK AND DEFENCE OF FLEETS. 305 good faith to the theory that if we knew accurately all the facts which can be established by experiment and ob- servation in peace time, we should have materials amply sufficient to guide us to complete success on the first occasion of putting our theory into practice against an enemy. These remarks are not unnecessary at the outset of my paper. There is not one of us Naval officers who has not either heard or expressed the most decided opinions on the efficiency of certain formations and the inefficiency of others ; yet I venture to say not 10 per cent, of us have ever heard any good reasons as to why one formation is better than another, and not 2 per cent, have ever thought out the matter even superficially for themselves. The dan- ger we run of committing ourselves to some definite theory of attack and defence without any inductive steps leading up to it, is real and tangible ; and if, instead of advocating a particular view, it should come to pass that I show the end father off than ever, and leave your minds open on the questions, I shall not consider I have done bad service. I must now advert to an opposite opinion on this matter which is held by men of greater practical experience than my own, and of deservedly greater weight. It is very strongly held by these that it is far more important to have a plan, than to have a good plan, of attack or defence. It is insisted that the Admiralty would be wise now, with our present information, in deciding on a particular formation and mode of attack, and in enforcing its use on our Admirals, so far as excluding all other plans from the Signal Book goes. The issue raised is very distinct, but it is not one I am called on to argue here. For, if I be wrong in suppos- ing a bad compulsory plan to be worse than no plan, still, 306 ESSAYS ON NAVAL DEFENCE. as no plau is yet adopted, such investigations as mine go to establish not only a plan, but, if properly conducted, a good plan, even though, as I before remarked, the attainment of one were so far ofE. It is now incumbent on me to state what the aim of my arguments will be. I understand the success of a fleet action will depend jointly or severally on four things, namely, material superi- ority, moral superiority, superior mobility, and superior position. Material superiority we have nothing to do with. If we have it, and an equality in the other three things, we shall win without a discussion. Moral superiority is often con- founded with strategy, and often spoken of as though it were a possession not only exclusively English, but incom- patible with strategic skill or even strategic plans. I hope I should be the last to despise that fire, dash, and stolid de- termination which hurled a Nelson on the van of the French at the Nile, and on the head of the Mole at Santa Cruz. I trust no English Naval Officer will ever forget that, guns or no guns, rams or no rams, torpedoes or no torpedoes, he who places himself most completely in the spirit of Nelson's orders to his captains is doing the best ser- vice to the State, and runs most chance of winning. If nerve gained naval victories for us a century ago, surely those who have it in superiority possess an increased power now ! But the instances I quoted of Nelson at the Nile, and Nelson at Santa Cruz, are sufficient to indicate that bravery and strategy combined are very much more power- ful than bravery alone. The brave man had better be in- telligently brave while he is about it. It may raise his reputation for pluck to win with great loss, but it will bene- fit the State more that he should win with small loss. THE ATTACK AND DEFKNCE OF FLEETS. 307 Besides, a maa cannot be argued into bravery, and he can be taught strategy. Again, mobility in a fleet must be attained before the latter can be strategically employed. I pre-suppose we have it in equality with the other side. Of the four quali- ties set out there remains now only the last — superiority of position. What constitutes it and how to gain it, is the sub- ject I intend to discuss. To those, therefore, and they are many, who pin their faith on the moral superiority given by audacity and nerve, and propose without any plan to rush upon an enemy's fleet and frighten him into submission, I have nothing to say of a controversial character. I am not about to argue whether audacity be a greater or a less powerful weapon than skill. But I am about to argue, and do maintain, that audacity supplemented by skill is irresistible, and my object is to arrive at some conclusion as to how your own Meet can be best disposed so as to allow your audacity to produce the greatest possible effect on your enemy with the least harm to yourself. I must now set out in order those points which, discussed in my last paper, or generally admitted, have, for the pur- poses of my present argument, all the force of facts, and must be acknowledged as such until they are controverted. First comes the possible speed of a fleet in action : we know that this ranges between, say, eight and .thirteen knots, and if I take a mean of ten knots, I shall place my- self in such a position that half my readers will say I put it too high, and the other half too low, a sufficient guarantee for being somewhere near the truth. Assuming such a speed, enables me to deal with the all-important relations of time and space ; will permit me to show what can and what cauDot be done by a fleet in the time allowed ; and X 2 308 ESSAYS ON NAVAL DEFENCE. how the skilful commander ma,y. avail himself of the limit which time im.poses on the enemy's movements.! Next comes the turning power of ships, which I showed in my last and former papers cannot be taken as to space, at a smaller arc than one with, a radius of two and a half times the ship's length ; and as to time, a reduction in speed over the arc of one-third. It is perhaps necessary to repeat here that this statement does represent in the rough an absolute fact ; and that the figures do give the smallest space combine I with the least time in which average ships can turn. If the space be diminished the time will be increased, and if the space be increased, so also will the tinie.2 If we now take 300 feet as the length of an ordinary iron- clad, we get an arc of turning for the ships of our fleet of 250 yards, and a time of turning through (say) eight points at ten knots, of two minutes. I must draw your particular attention to the foregoing figures, because I base my whole view of naval strategy upon them, not indeed on the exact numbers, but upon their relations to each other. These relations are, in my view, the bounds within which the tactician must work, and beyond which he will only fail in attempting to pass. It is no use to call them matters of details or assumptions, they are vital principles ; and the only assumption about them is the exactness of the figures. Ships may not be 300 feet in length, but the shortest turning ironclad which has ever been built, going at her highest speed, takes about a minute to turn through eight points on an arc whose diameter was 5'2 times her length, reducing her speed over the arc by more than one-tenth. 1 Such a fighting speed must still be considered proper. — Ed. ''■ The twin-screw modifies the space, but not materially the relations between time and space. — ED. THE ATTACK AND DEFENCE OF FLEETS. 309 The next point to be considered is the gun-power of ships. T laid it down last year from the best data obtain- able, that only about 10 per cent, of the shot fired from a sea-going ship would take effect upon another bro.idside- on, and at a fixed distance of 1,000 yards ; and that the highest speed of fire which could be calculated upon, was about one round in three minutes. The damage done by hits at that range was of course not easy to estimate, but except at close quarters, when the shot strike fair on the broadside, all allow it to be small : the effect of hits re- ceived when «nd-on is generally considered to be nil. I held the ram to be the effective weapon in a single- ship action, the gun being subordinate, unless the Harvey torpedo should supersede the former ; and while on this subject I must say two words. I have usually in my papers stated that the idea of the ram originated in our Service, with ttte gallant Admiral of the Fleet, Sir George SartoriuS. He will be pleased to know that another officer. Sir James Sulivan, was, contemporaneously with him, pressing the weapon on the notice of the Government, and assisting in that development which we are yet so far from seeing complete. Again, I have seen, since I last addressed you, the Harvey torpedo in action, and I have m^odified my views of it. It is not, in my opinion, so powerful a weapon as I formerly believed it to be. To use it effectually, special ships of. high speed must be employed, and even then, much more skill is required than I imagined necessary. It seems to me also, that the mitrailleuse ,or volley -gun will be a very effective defence against this torpedo. It would be used both to sweep the manipulators off the decks, aud also to destroy the torpedo itself. In any case, it must here be said that even when I read my last paper. 310 ESSAYS ON NAVAL DEFKNCE. I could not view the Harvey torpedo as an effective weapon in fleets. It is true tbat one or two special ships towing torpedoes, might, as an avcmt garde, throw a hostile fleet into some confusion ; but, as the enemy might equally well employ the same weapon, we should have a combat of torpedoes vessels between the fleets be- fore they met, which could not lead to decisive results.l If this torpedo is ever rendered powerless against friends, fleets might employ it with greater reliance on its power against enemies. I now arrive at a point on which there is not, and cannot be any data, but which universal assent has estab- lished as a fact. I allude to the general understanding that whatever forniations may be in future assumed by two hostile fleets in action, the ships composing them will always be end-on, and never broadside-on to the enemy. Some explanation is required to show how I look on it. In my last paper I endeavoured to show that, prevalent as the notion was that the end-on position was that which a ram would assume towards another ship in action, it was in reality a false one. I showed that this was quite a right position for a ship not herself a ram, and desirous to avoid being rammed, but that if a ram were so to range herself she could never strike at an advantage. I find now very many officers hold that I am wrong, not in upholding the advantage of making your stem take your enemy's broadside, but wrong in believing that two ships will seldom, or never, meet stem to stem. It is difficult to argue either side of the question, but I may note that the Russian gunboats never met stem to stem in their experi- ments ; and I may express my firm belief that one or other ' It is curious that according to some authorities, the more recent ■■ torpedo-boat " will succeed to this function, in cases. — Bd. ^ ^ ^ « ^ -.- > 5 « m »..».».». ^^ «, - DC ► \\N < iZ V 1 ^ , ;/M2 Vi \ •■''''■ CO ■^ ♦ 1 > s < s < " 1 1 « i ■3 |i - 1 oO :^ p V o 5 ' ■op < Ph — >^ < / o •- / --^-^ iZ ■m -^■- I^'" ^ •■ THE ATTACK AND DEFENCE OF FLEETS. 311 ship will in such a case swerve at the last moment, and pass broadside to broadside without any result from either ram.l Those who think otherwise must remember that there is no analogy between the old principle of getting broadside-on to your enemy at pistol range, and pounding him till either one or the other struck, and the stem-to- stem encounter between two rams. The superiority of the English seaman in our old wars lay in his muscle and his steadiness. The weakness of our enemies was never in material, but they failed in nerve and stolidity. It was the height of strategy to bring our strong points against his weak ones, and broadside to broadside did this in per- fection. But for one ship to run against another, stem-to- stem, is no strategy, but rather a reckless blind trusting to chance. The victory depends upon which ship turns out to be the hardest, and the spinning of a teetotum will represent the chances on either side, The strong probability is that if two ships met at speed, stem-to-stem, the shock would be so terrific that both combatants would instantly dis- appear. I am Baying nothing here of the policy of charging straight down upon your enemy in the belief that he will flinch from his end-on position before the last moment, and give you the opportunity you seek. Such a course may be the most excellent strategy, as you are opposing your pre- sumed strength of nerve toyoiir enemy's weakness. I have before said, however, that 1 have nothing to do with strategy of this kind, and if a stem-to-stem encounter is contemplated in any other view, it will, I think, be a very foolish proceeding. 1 This happened in the case of .the Bovmet ;ancl Meteor, French and German ships in the West Indies.— ED, 312 ESSAYS ON NAVAL DEFENCE. If there is anything to be said on the other side, I am not now aware of it, and 1 therefore base all my ideas on what I have here stated. Those, therefore, who think with me, will observe the instinct of the naval world has led it to contemplate the end-on position for hostile fleets, not as the best means of attacking with rams, but as the best means of frustrating an attack of rams. Our opponents will take the opposite view. The latter party will maintain that the ram domi- nates and prescribes the formation, and is itself the chief weapon ; I, on the contrary, conclude that the ram domi- nates and prescribes the formation, which is so good a defence against it, that the ram is not the chief weapon in fleet actions. And the inefficiency of the ram as the chief fleet weapon, once the end-on position is firmly established, seems to me to be argued by other considerations which I have not yet seen treated by any writer on tactics. If we examine the ramming tactics for single ships laid out in my last paper, and endeavour to apply them to fleets, we shall soon see, I think, their inapplicability. Take Diagram I, figs. 7 and 8, and Diagram III, fig. 1, of my former paper, and you will at once note that the mode of approach is of small value. If as and y, Figs. 7 and 8, were leaders of single columns in line ahead, as in Diagram IV, fig. 1, it is apparent either thai the leaders alone would encounter, or that the turn of a; to ram, throwing her broad- side open to the next astern of y, would be taken advantage of by that ship, and even if ce succeeded in ramming y, she would herself be rammed in turn. So if x and y were the port wing ships of single lines abreast, as in Diagram IV, fig. 2, their manoeuvres would have no reference to the re- mainder of the fleet. If x and y were not wing ships, but some other ships in the lines abreast, as in Diagram V, fig. THE ATTACK AND DEFENCE OF FLEETS. 313 1, then x must make his turn astern of his left hand neigh- bour; he lays himself open to attack by y's left hand neighbour, and breaks the order of his own line, cutting himself ofE from support at the same time. Should he, however, use the short turn, as in Diagram V, fig. 2, his manoeuvre will be baulked by his own left hand neighbour, to avoid whom he must exercise caution, and who more or less hides the object of his attack, just at the moment when all depends on his getting a clear view. He again lays him- self open to the attack of j/'s left hand neighbour, or, if he misses y, of his right hand neighbour. If OS and y, however, being leaders of lines ahead, choose the 4-point method of approach given in Diagram III, fig. 1, the rest of the fleet does not partake in any of the ad- vantages of the mode of advance, as may be seen from Diagram V, fig. 3. If, however, they were the leaders of columns in quarter-line, as in Fig. 4, their tactics would equally apply to the ships astern of them. But the difEer- ence is, that x is no longer solely occupied with his attack. If his own next astern by any accident lets y's next astern slip past him, oo has two ships upon him, and fights at a disadvantage. We see running through all these positions a principle by which, in formation, one ship covers or guards another from a ramming attack, and renders useless the methods which are available between single ships. The fleet which rigidly maintains its end-on position, and whose ships only swerve from that to deliver their blow upon the enemy, who presents his broadside while attempting to ram the ships to whom they are guards, goes into action with an advantage, for it runs no such risks of being rammed as its opponents, who seek to attack in that manner, and while it never drops its own guard, it is ready to take advantage of any slip its enemy may make. 314 ESSAYS ON NAVAL DEFENCE. Naval tactical strategy, therefore, ■while it dictates an attack by the ram by single ships, as the most effective means of obtaining the victory for him -who is most skilful, does not seem to me to advise that policy in a fleet attack. Yon must beat your enemy in some other way. Before leaving this part of my subject, it is necessary to point out that some ships in every formation have no guards, and are open to the same attack as single ships. The rear ships in line ahead are open to the ramming attack on both sides ; and the wing ships in lines abreast and quarter lines are open to attack on their outer sides. Hence, although you cannot, as it seems to me, make your general effort a ramming attack, you will be foolish to avoid' any opportunity which offers of attacking particular parts of your enemy in that manner. We are now in a condition to apply the principles we have brought out to the actual business of my paper, the Attack and Defence of Fleets. In all sea-fights of former ages, we see either of two con- ditions ; both fleets equally ready for the combat, or one assuming from the outset the attack, and the other the defence ; the former condition is rare. Hitherto, I believe, no case has occurred where — as in so many battles on land — a skilful movement has converted the defence into an attack. The most that could be done in former times was practised by the French, before the revolutionary war, in taking advantage of the weakness of the British attack to damage them seriously while keeping themselves out of harm's way. Clerk of Eldin shows that in the attack from to windward, generally practised by us before Lord Rod- ney's victory changed our views, we really offered a por- tion of our fleets to the whole fire of the enemy, as shown in Diagram V, fig. 5, and our van becoming disabled from THE ATTACK AND DEFENCE OF FLEETS. 315 this cause, the French were in a position to bear away to leaward to re-form, and to repeat the manoeuvre, which they usually did. Sir John Jervis at St. Vincent, and Lord Nelson at the Nile, are brilliant examples of an opposite mode of proceed- ing, and though the approach of Lord Nelson at Trafalgar might seem a recurrence to old methods, it was not really so, as the enemy's fire was divided between two vans, and the approach was direct, and as rapid as it could be, instead of the slow and " lasking " approach, asit was called, shown in Fig. 5, Diagram V. In the changed condition of things now, we must be very careful to guard against following history too blindly as our guide ; but, at the same time, we must by no means neglect to avail ourselves of the lessons she really teaches ; though, therefore, the manner has passed away, the inatter remains as worthy of adoption as ever it was. I think now that steam has done much to alter the former state of affairs, and that an inferior fleet may, when direct attack is not at first attempted, convert a defence into an attack, and perhaps even gain a victory. The principles of a skilful attack or defence must ever remain the same ; they must always be the offering a superior force to an inferior ; and if a part of the enemy's fleet is made to bear the brunt of the whole of your own, the greatest tactician can do no more. I am sorry, however, to believe that we are at present drawing more inspiration from the manner of our fore- fathers in naval tactics than from the matter. I do not think we have shaken ourselves sufficiently clear of the traditions of naval sea fights to perceive the laws which underlie them, and become applicable to our own times. In days of yore we had a broadside position ; small sail 316 ESSAYS ON NAVAL DEFENCE. and low speed. Now we have the end-on position, and great speed. I do not think, from all I have seen and heard, that naval minds habitually dwell on the speed at which future actions must be fought. It is known and acknowledged that a ship without speed, if met by a ship with speed, is doomed to certain destruction by ramming, but in spite of this, the picture of a fleet action naval men have before their eyes, is always a confused assem- blage of ships more or less stationary. It is quite common to hear it said that " the best tactics are for every captain to put himself alongside an enemy's ship," as if such a thing were now possible, unless the enemy's ship were a consenting party. The French system of tactics did much, and Lissa did more to confuse the picture of a future sea fight, and to paint it as a meUe of independent attacks. The melee at Lissa was entirely due to the broadside position of the Italian fleet and its want of speed ; two concomitant blunders which no commander will ever be mad enough to bring together again. Had it been other- wise, TegethofE might have had his melee to himself, but the Italians would have been out of it from their own impetus. If two fleets charge one another at ten knots in the end-on position, three minutes will elapse between their being a mile apart and their meeting, and in another three minutes they will again be a mile apart. If the very instant after one fleet had passed through the other, they put their helms hard over, still the other fleet would be three-quarters of a mile away before the first was in pursuit. Under such circumstances the only melee will be amongst the wounded birds, and the type of the battle would be a rash, a contact, a separation, a re- formation, again facing each other, another rush, aud the same thing repeated. THE ATTACK AND DEFKNCE OF FLEETS. 317 The other type of action — still due to speed and the end-on position, would he where one fleet retires before the other uritil, by happy skill, or by happy accident, it is able to face its pursuer with advantage. How to face your enemy with this advantage, how to bring your whole fleet on a portion of his when facing him, seems to me the problem before us. We shall all be agreed, I think, that anything like elaborate manoeuvring is out of the question, except in the process of retiring. The mere moment of time which elapses between the coming into range of two approaching fleets and their shock, renders either mancBuvring or sig- nalling absolutely out of the question. Nay, even after sighting an enemy's fleet — say ten miles off, he will be a hardy admiral who attempts to do more than throw his fleet into the formation he intends to fight in. In such circumstances, the fewer signals the better, as a mistake might be fatal, and the chances of mistake are trebled when the nerves are tightly strung, as they would be at such a moment of excitement. The very numerous, and sometimes eccentric, fighting formations which are proposed for adoption by our own and other Navies may be classified under four heads ; which, on still closer examination, may for the purposes of argument, be resolved into two. These are — (1). An extended front, with small depth. (2). A narrow front with great depth. (3). The mass or square, where depth and front became equalised. (4). The system of groups however disposed. The principle doing that the attack or defence is not concentrated, each group making itself felt as occasion ofEers. 318 ESSAYS ON NAVAL DEFENCE. The mass, or square, must possess in a less degree the advantages and disadvantages of the extended and narrow front, and of the small and great depth. The groups must be disposed either along an extended front or along an extended depth, and, therefore, must, so long as they remain in formation at all, possess the weak- ness or the strength of those formations. If, however, we reflect a moment, we shall see that when an enemy's fleet is approaching in an order of battle, all that can be detected in the few minutes of time allowed, will be either its extended front or its extended depth. Therefore, although if time permitted I might go into greater detail, I think that I shall best argue out the principles I have in view by imagining all formations classed under the two first heads, and considering the relations between an extended front as opposed to an ex- tended front ; a narrow front and great depth as opposed to an extended front and small depth, and a narrow front and extended depth as opposed to the same formation. A few words will then sufiBoe to treat of the mass or square, and of the system of groups. It will also, I think, conduce to clearness if I do not go beyond the two representative formations of the extended front and the extended depth, namely, the single column in line abreast and the single column in line ahead. The attack I define to be when the ships keep their heads towards the enemy, advancing, or trying to advance on him. The defence is when the fleet retires before the enemy. In the attack there is always one enormous advantage on the side of that fleet which takes the initiative. Ships cannot move simultaneously, except by signal. One or two ships may turn so closely after each other, moved by THE ATTACK AND DEFENCE OF FLEETS. 319 a common impulse, as to be practically simultaneous in their action ; but this cannot be carried throughout a fleet. It follows, then, if there is not time to make a signal after the nature of the attack is disclosed, neither will there be time to manoeuvre so as to counteract it. The Admiral assuming the initiative, or advancing in such a way as enables him to assume it without a signal, may do so with some security against a counteracting move- ment. While he who waits till the attack is developed in the hope of counteracting it, runs the risk of not being allowed time to do so. Taking, now. Diagram VI, we have two fleets, 2,000 yards apart, approaching at the rate of 20 miles an hour. The fleet A may pass straight on, bearing down upon B, without alteration of course. In the three minutes elapsing between getting into range, and contact, one, or at most two rounds may be exchanged. Supposing both fleets had been stationary at 1,000 yards, and each ship in A fired two guns at B, between one and two shot might strike, with a chance of penetration or damage at its minimum. But the fleet target, so far from being stationary, is altering its range eleven yards in a second. Under such circumstances, to fire is to waste powder. A had better proceed without firing, and with his guns concentrated right abeam and horizontal, ready to discharge point-blank into the enemy in passing, should his ships maintain their end-on position and so elude the ram. B, under present circumstances, ought to reserve his fire, and hence, when the two fleets have passed through one another, they will have fought on an absolute equality, and any less damage done to one or the other must be due to stronger plating, bad practice on the other side, or the chapter of accidents. But, consider how very dangerous this method of en- 320 ESSAYS ON NAVAL DEFENCE. gaging -will be to the friends on both, sides. In the con- fusion, excitement, and smoke, how more than likely is it that a friend will receive the broadside intended for an enemy ? True, each fleet runs an equal risk of this, just as each runs an equal risk of being rammed. But to run these risks is not tactics, and it is, I think, plain on these grounds that an attack made direct, by an extended front, ought not to be met by a counter attack of the same nature. It will be opan to A, if there is time to make the signal before getting into range, to put in force the application of ramming taetics formerly mentioned, and by altering course together four points either way, to endeavour to force a similar movement on the enemy, and thus to con- vert an artillery combat into a trial of skill in ramming. If this movement were made at the moment of coming into range, the new positions of" the fleets would be at p and rj. It is pretty clear that A's manoeuvre has no forcing effect whatever on B, who, on the contrary, appears to have cer- tain advantages placed in his hands which he had not before. It is true that, for a moment, the artillery of A may be held superior to that of B, inasmuch as he can probably bring more guns to bear. But this advantage passes away as A moves to the right along the front of B ; and besides, A receives the shot of B more directly perpendicular to his broadside than does B those of A. But while the port-wing ship of B is guarded from rams by her right-hand neighbour, the port-wing ship of A is not guarded at all, and should be the object of B's attack by ramming. Except these '' alterations of course together," which must be ordered by signal before getting into range, there THE ATTACK AND DEFENCE OF FLEETS. 321 appears little that A caa do so long as he remains in line abreaet ; and if it be as appears, that he gains no advan- tage either in a direct advance or a four-point advance it seems to me he must give up the extended front if he wishes to attack an extended front with an advantage. Let us therefore examine the extended and narrow- fronts as opposed to each other. This we have in Diagram VII, fig. 1. We suppose two fleets, A and B, observing one another at sufficient distance to allow of consideration and to the coming to the conclusion to attack : but A de- termines to do so in a formation with a narrow front, and B with an extended front. The headmost ship of A has approached to within 2,000 yards of B's ships. Let us see how matters stand between them. A's leader is opsn to the fire of the whole of B's bow guns, a fire which we have before shown to be ineSective. That is her whole disad- vantage. On the other hand she is within three minutes of contact with B's fleet, and yet has not disclosed the nature of her attack. Supposing the Admiral of A to be leading, his orders would be to the ships astern of him to follow his motions together, as nearly as possible to concen- trate their guns at point blank, right ahead, and to pour in their shot on the instant of passing an enemy's ship. A has three attacks open to him : the centre, or either flank, of his enemy ; and leaving him in doubt up to within three minutes of commencing his attack, it is manifestly impossible for B to counteract him, even if there were a movement capable of doing it. Suppose A chooses to pierce the centre, and therefore simply continues his course ; as he passes between two enemy's ships he certainly re- ceives their two broadsides ; but if he be equal in power on both sides he gives them as good as he gets, with this advantage, that his shot which miss one enemy's ship may 322 ESSAYS ON NAVAL DEFENCE. hit another ; while the enemy's shot which miss him may damage their friends. But if A's leader has already been subjected to bow fire from those ships between which he passes, they will hardly be ready in the time to give him broadside fire as well from these guns. But in any case, the moment A's leader has exchanged broadsides with her enemies, and long before they are in a condition to fire again, a succession of fresh ships pass into her place at the rate of one every twenty seconds or thereabouts. The two ships between which A is efEecting his passage will thus receive five broadsides apiece in about a minute and a half, without more than a single reply, and if this is not enough for them, I think it ought to be.l Here we have the process of " doubling on the enemy," as I conceive it must in future be practised. The principle remains the same as ever, only the detail has altered with the times. Instead of doubling simultaneously and so placing a ship betwixt two fires, we must now double in succession, serving her with a continued succession of fresh ships. The only objection I can see to this centre attack is, that you lay yourself open to the fire of both flanks on your near approach, whereas, by attacking on the flank, you can receive no more than half that amount. In this attack, if the Admiral chooses to threaten the centre till close up with the enemy, which I think will be hardly necessary, his ships should turn together towards the intended flank and then turn again into line ahead, as shown in the diagram, pouring successive broadsides into the enemy's wing-ship in passing, A's rear ship 1 Whether under such circumstances the ships between which A's fleet passes would dare to use their Whitehead torpedoes is an interesting problem. — Ed. THE ATTACK AND DEFENCE OF FLEETS. 323 should, I think, be directed to attack the wing-ships of the enemy with his ram, and for this purpose should steer further out than the ships ahead, so as to give himself room to turn. His orders should be not to embroil himself by making a second attempt if he misses the first, — indeed, he can hardly obtain a second opportunity, — but to follow the rest of the fleet, which should re-form with their heads towards the enemy, ready to act again as may be necessary. There are in this kind of combat a variety of circum- stances to be noted which seem to me to tell in favour of A's attack. If there is no wind, A's ships after the leader, will observe B's wing-ships emerging from the smoke of their own and A's guns, before they themselves have entered it. They will consequently be more m.asters of the situation than B's ships can possibly be. If B's whole line continues to fire from his bow guns, as no doubt he would, there is the greatest danger of his line getting into confusion, and also of some of the shot intended for ail enemy reaching no further than a friend. It is, I believe, a fact that with modern heavy guns the compasses are thrown completely out of gear, so that no formation can be maintained by compass while firing. 1 In A's advance the compass is not appealed to at all, as each ship simply follows her next ahead in the closest possible order : and although the formation will probably be broken ultimately, this will not happen till its work has been done, and it is clear of smoke in rear of the enemy. If the wind were blowing towards the attacked flank across the enemy's front, his view will be interrupted, and 1 Subsequent experience showed me that Sir Wm. Thomson's (Lord Kelvin's) compass modifies this a good deal.— Ed. 324 ESSAYS ON NAVAL DEFENCE. his fire will slack. But the smoke may also shroud A's ships from one another even before they tire, and their broadsides may be thrown away. If the wind is from the attacked flank, A will always be in the clear, while the ships of B's line will be shrouded, each one by the smoke of his neighbour. I think, therefore, that A should choose the weather flank for his attack. If the wind be with B's fleet, so much the worse for him, while it will not affect A. While, if the wind be with A's fleet, the conditions will be those of a calm, except that A will be longer in his own smoke after he lia.s passed the enemy. But while showing the advantages of thus opposing a narrow to an extended front, we must not omit to ascer- tain what possibilities of defence lie in the extended front. At first sight, many movements will suggest themselves as practicable, but when we apply the rigid standards of time and space, we shall think differently. Remember, there are but three minutes in which B must form and execute his plan. On the face of it, there- fore, there can be no combined manoeuvre not previously arranged. No previous arrangement could embrace more than a single movement, yet there is no single movement preserving the line abreast, which can be executed in the time and space except by surrendering the attacking position. Suppose B were to hope to swing his line round on his port wing-ship as the pivot? To do this, the port wing- ships, the very object of his solicitude, must reduce their speed, enabling A's rear-ship, already warned, to ram them with ease. But in no case can B's starboard wing-ship come upon A's rear-ship in time. Again, B surrenders his bow -fire in attempting any manoeuvre, for it is admitted by all impossible to manoeuvre in smoke. Besides, any THE ATTACK AND DEFENCE OF FLEETS. 325 one who has experience of fleet manoeuvring, is aware of the difficulty of preserving the formation when swinging round, even for drill purposes. Single ships, it has been said, may pierce A's line or ram him. This is so, but only by passing astern of their friends, and so separating from them and plunging into the midst of their enemies, can they effect their purpose. But then they pass at once into the heaviest of the smoke, and run at least as great a risk of destruction themselves as they bring upon their enemies. On the whole, therefore, my view is, that an extended front is an exceedingly weak formation for attack, and ought to saccumb to the narrow front in all cases where things are otherwise equal. But the extended front may, when time permits, be changed for the narrow one. If B, surrendering his idea of the line abreast, were, on perceiving A's approach in line ahead, to meet him in the same formation, he would advance his port wing-ship and form astern of him. This would give us the narrow front as opposed to the narrow front, shown in Diagram VII., fig. 2, and I think we see the balance is restored, and that if both fleets so advance, they will fight on an equality. It is of course useless, and perhaps foolish, for the leaders to open fire till abreast of each other; they will then exchange their broadsides, and if they both pass on, will each receive the broadside of fresh ships before they can reply effectually. Here the same qualities might stand the British seaman gunner in as good stead as formerly provided, that is, that machinery more perfect for working guns is not adopted by other nations, and a rapidity of fire obtained, which we cannot compete with. 326 ESSAYS OK NAVAL DEFENCK. But without this, or in spite of this, A may by proper orders to his ships, gain an advantage over B. Suppose, for instance, that A's leader, and each ship astern of him, were ordered the moment they had fired their broadsides, to turn sharp off to starboard, B's fresh ships would never get the opportunity of firing at all, and his leader and her next astern, would have received the fire of the whole of A's ships. When the smoke cleared away, A would find himself in quarter line with B in his rear, and might determine on the next stage of his attack. I have now discussed as closely as time permits, the principles of Naval Tactics in the attack as they have presented themselves to me after such limited examina- tion as I have been able to give to them. It will be seen that I believe the extended front to be a weak formation, and that in no case should it be taken up in an attack. It has appeared also in the course of my enquiry that the bow-fire, or extreme training of guns, ia not of great value, and that more is to be done by broad- side fire in attacking fleets. These conditions appear reversed when one fleet retires before another. Then, uulesB the pursuer can enforce by his speed, or the pursued takes up for himself, the position of attack, the result must depend on the goodness of the gunnery practice. The pursued must spread out an extended rear, and the pursuer an extended front, in order to get the full value of their artillery. Here the distances will be fairly permanent, and the bow and stern fires become effective. I cannot conceive, hoveever, a decisive victory gained on such principles ; and for the defence, I would rather convert it into an audacious attack upon either flank of the pursuer in the manner before described. I have already stated that if a formation, such as the THE ATTACK AND DEFENCE OF FLEETS. 327 hollow square proposed in Russia, possesses depth and extended front in combination, it possesses also the weak- nesses and strengths of each quality, and therefore', if the better qualities of the line ahead be opposed to the less good ones of the shorter side of a square, there will still be an advantage, though not so great on the part of the former. These compromises seem to me to be proper for adoption by such nations as, from their want of naval prestige, may be more solicitous to guard against defeat then to ensure victory. I mast own my sympathies lie in the direction of audacity, and a determination to win or to lose all ; and hence I do not so much concern myself with half measures. It will be seen that I lay great stress on compactness and concentration in attack, and I am in consequence opposed to systems of reserves of separate fleets acting conjointly ; or lastly, to the attack or defence by groups. I cannot at present see how, when fleets are at speed, a group can act independently without running the great risk of finding itself surrounded by enemies, and beyond the support of its friends. Suppose a group such as Figs. 3 and 4, diagram VII., opposed to even the same number of ships only, in close order in line ahead. The broadside fire of one ship in each formation is masked, and in Fig. 3 the attacking force of three ships would receive one broadside from the leader at double distance, and one from the wing-ship at close distance. But this wing-ship would get in return three broadsides at close distance. So with four ships in line ahead attacking the group of four. The leader might sustain one broadside at close distance, and two at double distance. But the wing-ship would sustain foar broadsides at close quarters. Then observe the weak- ness of these groups in the matter of ramming. Fig. •!! 328 ESSAYS ON NAVAL DEFENCE. has two ships out of three, and Fig. 4 three ships out of four, unguarded. Such an opportunity for the ram-ships of a line ahead is all that can be desired, especially in Fig. 4, for the ram which misses the wing-ship, will almost to a certainty catch the rear. Such, then, is my slight summary of the line I conceive our study of Naval Tactics should take. I should be very sorry, indeed, to dogmatise on a subject which is to all intents and purposes a new science, but I hope to have shown that there are sound principles to be got at even in peace time, if we will only take suffii3ient trouble to find them.

COLOMB, Gold Medallist Royal United Service Institution, and Lecturer on Naval Strategy and Tactics in the Royal Naval College at Greenwich. OPINIONS OF THE PRESS. " The book is almost a pioneer of its class, for, strange to say, the literature of the greatest Naval Power in history has no authoritative treatise on the principles of Naval Warfare. . . . Ought to have an absorbing interest to every English- man who loves his country and cares for its history." — Times. " A serious and important contribution to a vastly interesting study." — Daily Telegraph. " The gallant author, who is a most prolific writer on pro- fessional subjects, deals with every phase of the question of naval warfare. . . . There are numberless illustrations, plans, diagrams, maps, &c., to assist the reader, and the bulky volume should, upon its merits, generally find many readers." Hants Telegraph. " There are other roads to fame than the path which leads to victory, and there are services which a man may render to his count4;v perhaps greater than to die. Englishman have reason to be proud of the wisdom, the public spirit, the wide knowledge, and the singleness of purpose displayed in every page of Admiral Colomb's great work. . . . Into the technical details we have no space to enter, but we can only hope that so great a master of naval tactics will give the world the further benefit of his researches and experience in some future volume." — Murray's Magazine. " The book it admirably illustrated with maps and charts of the theatres of war, and wifli plans of the various ports and haibours attacked, and the study of it will give a valuable insight into the causes which led to our maritime superi- ority." — Graphic. '' The subject is treated historically, thus adopting the only sound plan in the attempt to elucidate principles of warfare. . . . . It is a matter of congratulation that the British navy has prpduced such a work."— Manchester Guardian. " Admiral Colomb deals with a subject of peculiar interest and importance with a pen guided by experience and authority. His narrative of naval warfare, regarded merely as a narrative, is one that will be welcomed by all classes of readers. The book possesses undoubted value for experts ; and in this respect the writer says what he has to say with reason and force, and bases (his conclusions on what is clearly a careful observation of historical facts The book is admirably supplied with numerous maps and diagrams of ^reat merit, and is otherwise produced in a style that leaves little to be desired." — Scotsman. "Such a work ought to find its way into every reference library, as well as into the hands of all who are preparing for the Service." — Standard. " It is strange that we should have had to wait so long for such a work ; but it is highly satisfactory to find that, now that the work has been produced, it is of a character that will have a lasting value, and that cannot fail to promote further and fruitful study of questions that are all-important to a naval power like England." — Vanity Fair. "Admiral Colomb is to be heartily congratulated on the result of the thought, labour, and time which must have been expended in the preparation of this great work." — Jownal Royal United Service Institution. " This able work should be highly appreciated." — Morning Post.

The Great Barrier Reef of Australia, represented by a vast rampart of coral origin, extending for no less a length than twelve hundred miles from Torres Straits to Lady Elliot Island on the Queensland coast, takes rank among the most notable of the existing wonders of the world. Built up by the direct and indirect agency of soft-fleshed polyps of multitudinous form and colour, it encloses betwixt its outer border and the adjacent mainland a tranquil ocean highway for vessels of the heaviest draught. To the naturalist, and more particularly to the marine biologist, the. entire Barrier area is a perfect Eldorado, its prolific waters teeming with animal organisms of myriad form and hue representative of every marine zoological group. The author's qualifications for the task he undertakes are emphasised through the circumstance of his having been occupied for the past eight years as Inspector and Commissioner of Fisheries to various of the Australian Colonies, the three later years having been devoted more exclusively to investigating and reporting to the Queensland Government upon the fishery products of the Great Barrier District. A prominent feature in this work will consist of photographic views of London: 13, Waterloo Place, Pall Mall, S.W. W. H. Allen 6- Co!s New and coral reefs of various construction and from diverse selected localities, together with similar and also coloured illustrations and descriptions of the living corolla, coral-polyps, and other marine organisms commonly associated on the reefs. These photographic illustrations taken by the author are, from both a scientific and an artistic standpoint, of high intrinsic merit and also unique in character, representing, in point of fact, the first occasion on which the camera has been employed for the systematic delineation of these subjects. \Ready in January, F.

While the work was progressing, however, it was found that the mere reduction of the Arabic portion would not suffice to answer the purpose intended. It became evident not only that much that was superfluous had to be eliminated, but that, on the other hand, many additions were urgently required, and furthermore, that the material had to be re-arranged on new and distinct principles. At the same time, it was soon felt that the fresh matter to be introduced into the Persian part exceeded the limits contem- plated, and necessitated in this respect a considerable extension of the primary plan.
