Preparedness for naval war therefore consists not so much in the building of ships and guns as it does in the possession of trained men in adequate numbers, fit to go on board at once and use the material, the provision of which is merely one of the essential preparations for war. The word "fit" includes fairly all that detail of organization commonly called mobilization, by which the movements of the individual men are combined and directed. But mobilization, although the subjects of it are men, is itself a piece of mental machinery. Once devised, it may be susceptible of improvement, but it will not become inefficient because filed away in a pigeon-hole, any more than guns and projectiles become worthless by being stored in their parks or magazines. Take care of the pence and the pounds will take care of themselves. Provide your fit men,—fit by their familiarity not only with special instruments, but with a manner of life,—and your mobilization is reduced to a slip of paper telling each one where he is to go. He will get there.
That a navy, especially a large navy, can be kept fully manned in peace—manned up to the requirements of war—must be dismissed as impracticable. If greatly superior to a probable enemy, it will be unnecessary; if more nearly equal, then the aim can only be to be superior in the number of men immediately available, and fit according to the standard of fitness here generalized. The place of a reserve in any system of preparation for war must be admitted, because inevitable. The question, of the proportion and character of the reserve, relatively to the active force of peace, is the crux of the matter. This is essentially the question between long-service and short-service systems. With long service the reserves will be fewer, and for the first few years of retirement much more efficient, for they have acquired, not knowledge only, but a habit of life. With short service, more men are shoved through the mill of the training-school. Consequently they pass more rapidly into the reserve, are less efficient when they get there, and lose more rapidly, because they have acquired less thoroughly; on the other hand, they will be decidedly more numerous, on paper at least, than the entire trained force of a long-service system. The pessimists on either side will expound the dangers—the one, of short numbers; the others, of inadequate training.
Long service must be logically the desire, and the result, of voluntary systems of recruiting the strength of a military force. Where enrolment is a matter of individual choice, there is a better chance of entrance resulting in the adoption of the life as a calling to be followed; and this disposition can be encouraged by the offering of suitable inducements. Where service is compulsory, that fact alone tends to make it abhorrent, and voluntary persistence, after time has been served, rare. But, on the other hand, as the necessity for numbers in war is as real as the necessity of fitness, a body where long service and small reserves obtain should in peace be more numerous than one where the reserves are larger. To long service and small reserves a large standing force is the natural corollary. It may be added that it is more consonant to the necessities of warfare, and more consistent with the idea of the word "reserve," as elsewhere used in war. The reserve in battle is that portion of the force which is withheld from engagement, awaiting the unforeseen developments of the fight; but no general would think of carrying on a pitched battle with the smaller part of his force, keeping the larger part in reserve. Rapid concentration of effort, anticipating that of the enemy, is the ideal of tactics and of strategy,—of the battle-field and of the campaign. It is that, likewise, of the science of mobilization, in its modern development. The reserve is but the margin of safety, to compensate for defects in conception or execution, to which all enterprises are liable; and it may be added that it is as applicable to the material force—the ships, guns, etc.—as it is to the men.
The United States, like Great Britain, depends wholly upon voluntary enlistments; and both nations, with unconscious logic, have laid great stress upon continuous service, and comparatively little upon reserves. When seamen have served the period which entitles them to the rewards of continuous service, without further enlistment, they are, though still in the prime of life, approaching the period when fitness, in the private seaman or soldier, depends upon ingrained habit—perfect practical familiarity with the life which has been their one calling—rather than upon that elastic vigor which is the privilege of youth. Should they elect to continue in the service, there still remain some years in which they are an invaluable leaven, by character and tradition. If they depart, they are for a few years a reserve for war—if they choose to come forward; but it is manifest that such a reserve can be but small, when compared with a system which in three or five years passes men through the active force into the reserve. The latter, however, is far less valuable, man for man. Of course, a reserve which has not even three years' service is less valuable still.
The United States is to all intents an insular power, like Great Britain. We have but two land frontiers, Canada and Mexico. The latter is hopelessly inferior to us in all the elements of military strength. As regards Canada, Great Britain maintains a standing army; but, like our own, its numbers indicate clearly that aggression will never be her policy, except in those distant regions whither the great armies of the world cannot act against her, unless they first wrench from her the control of the sea. No modern state has long maintained a supremacy by land and by sea,—one or the other has been held from time to time by this or that country, but not both. Great Britain wisely has chosen naval power; and, independent of her reluctance to break with the United States for other reasons, she certainly would regret to devote to the invasion of a nation of seventy millions the small disposable force which she maintains in excess of the constant requirements of her colonial interests. We are, it may be repeated, an insular power, dependent therefore upon a navy.
Durable naval power, besides, depends ultimately upon extensive commercial relations; consequently, and especially in an insular state, it is rarely aggressive, in the military sense. Its instincts are naturally for peace, because it has so much at stake outside its shores. Historically, this has been the case with the conspicuous example of sea power, Great Britain, since she became such; and it increasingly tends to be so. It is also our own case, and to a yet greater degree, because, with an immense compact territory, there has not been the disposition to external effort which has carried the British flag all over the globe, seeking to earn by foreign commerce and distant settlement that abundance of resource which to us has been the free gift of nature—or of Providence. By her very success, however, Great Britain, in the vast increase and dispersion of her external interests, has given hostages to fortune, which for mere defence impose upon her a great navy. Our career has been different, our conditions now are not identical, yet our geographical position and political convictions have created for us also external interests and external responsibilities, which are likewise our hostages to fortune. It is not necessary to roam afar in search of adventures; popular feeling and the deliberate judgment of statesmen alike have asserted that, from conditions we neither made nor control, interests beyond the sea exist, have sprung up of themselves, which demand protection. "Beyond the sea"—that means a navy. Of invasion, in any real sense of the word, we run no risk, and if we did, it must be by sea; and there, at sea, must be met primarily, and ought to be met decisively, any attempt at invasion of our interests, either in distant lands, or at home by blockade or by bombardment. Yet the force of men in the navy is smaller, by more than half, than that in the army.
The necessary complement of those admirable measures which have been employed now for over a decade in the creation of naval material is the preparation of an adequate force of trained men to use this material when completed. Take an entirely fresh man: a battleship can be built and put in commission before he becomes a trained man-of-war's man, and a torpedo-boat can be built and ready for service before, to use the old sea phrase, "the hay seed is out of his hair." Further, in a voluntary service, you cannot keep your trained men as you can your completed ship or gun. The inevitable inference is that the standing force must be large, because you can neither create it hastily nor maintain it by compulsion. Having fixed the amount of material,—the numbers and character of the fleet,—from this follows easily the number of men necessary to man it. This aggregate force can then be distributed, upon some accepted idea, between the standing navy and the reserve. Without fixing a proportion between the two, the present writer is convinced that the reserve should be but a small percentage of the whole, and that in a small navy, as ours, relatively, long will be, this is doubly imperative; for the smaller the navy, the greater the need for constant efficiency to act promptly, and the smaller the expense of maintenance. In fact, where quantity—number—is small, quality should be all the more high. The quality of the whole is a question of personnel even more than of material; and the quality of the personnel can be maintained only by high individual fitness in the force, undiluted by dependence upon a large, only partly efficient, reserve element.
"One foot on sea and one on shore, to one thing constant never,"
will not man the fleet. It can be but an imperfect palliative, and can be absorbed effectually by the main body only in small proportions. It is in torpedo-boats for coast defence, and in commerce-destroying for deep-sea warfare, that the true sphere for naval reserves will be found; for the duties in both cases are comparatively simple, and the organization can be the same.
Every danger of a military character to which the United States is exposed can be met best outside her own territory—at sea. Preparedness for naval war—preparedness against naval attack and for naval offence—is preparedness for anything that is likely to occur.
