Lessons of the war with Spain and other articles. Alfred Thayer Mahan
from the first have been stationed before Cienfuegos; for each division, as has been said, could with military propriety have been risked singly against Cervera's four ships. This was not done, because it was possible—though most improbable—that the Spanish squadron might attempt one of our own ports; because we had not perfect confidence in the harbor defences; and because, also, of the popular outcry. Consequently, the extremely important port of Cienfuegos, a back door to Havana, was blockaded only by a few light cruisers; and when the Spanish squadron was reported at Curaçao, these had to be withdrawn. One only was left to maintain in form the blockade which had been declared; and she had instructions to clear out quickly if the enemy appeared. Neither one, nor a dozen, of such ships would have been the slightest impediment to Cervera's entering Cienfuegos, raising our blockade by force; and this, it is needless to add, would have been hailed in Spain and throughout the Continent of Europe as a distinct defeat for us,—which, in truth, it would have been, carrying with it consequences political as well as military.
This naval mishap, had it occurred, would have been due mainly to inadequate armament of our coasts; for to retain the Flying Squadron in the Chesapeake, merely as a guard to the coasting trade, would have been a serious military error, subordinating an offensive operation—off Cienfuegos—to one merely defensive, and not absolutely vital. "The best protection against an enemy's fire," said Farragut, "is a well-directed fire from our own guns." Analogically, the best defence for one's own shores is to harass and threaten seriously those of the opponent; but this best defence cannot be employed to the utmost, if the inferior, passive defence of fortification has been neglected. The fencer who wears also a breastplate may be looser in his guard. Seaports cannot strike beyond the range of their guns; but if the great commercial ports and naval stations can strike effectively so far, the fleet can launch into the deep rejoicing, knowing that its home interests, behind the buckler of the fixed defences, are safe till it returns.
The broader determining conditions, and the consequent dispositions made by the Government of the United States and its naval authorities, in the recent campaign, have now been stated and discussed. In them is particularly to be noted the crippling effect upon naval operations produced by the consciousness of inadequate coast defences of the permanent type. The sane conclusion to be drawn is, that while sea-coast fortification can never take the place of fleets; that while, as a defence even, it, being passive, is far inferior to the active measure of offensive defence, which protects its own interests by carrying offensive war out on to the sea, and, it may be, to the enemy's shores; nevertheless, by the fearless freedom of movement it permits to the navy, it is to the latter complementary,—completes it; the two words being etymologically equivalent.
The other comments hitherto made upon our initial plan of operations—for example, the impropriety of attempting simultaneous movements against Puerto Rico and Cuba, and the advisability or necessity, under the same conditions, of moving against both Cienfuegos and Havana by the measure of a blockade—were simply special applications of general principles of warfare, universally true, to particular instances in this campaign. They address themselves, it may be said, chiefly to the soldier or seaman, as illustrating his especial business of directing war; and while their value to the civilian cannot be denied,—for whatever really enlightens public opinion in a country like ours facilitates military operations,—nevertheless the function of coast defence, as contributory to sea power, is a lesson most necessary to be absorbed by laymen; for it, as well as the maintenance of the fleet, is in this age the work of peace times, when the need of preparation for war is too little heeded to be understood. The illustrations of the embarrassment actually incurred from this deficiency in the late hostilities are of the nature of an object lesson, and as such should be pondered.
At the same time, however, that attention is thus called to the inevitable and far-reaching effect of such antecedent neglects, shown in directions where men would not ordinarily have expected them, it is necessary to check exaggeration of coast defence, in extent or in degree, by remarking that in any true conception of war, fortification, defence, inland and sea-coast alike, is of value merely in so far as it conduces to offensive operations. This is conspicuously illustrated by our recent experience. The great evil of our deficiencies in coast armament was that they neutralized temporarily a large part of our navy; prevented our sending it to Cuba; made possible that Cervera's squadron, during quite an interval, might do this or that thing of several things thus left open to him, the result of which would have been to encourage the enemy, and possibly to produce political action by our ill-wishers abroad. Directly upon this consideration—of the use that the Flying Squadron might have been, if not held up for coast defence—follows the further reflection how much more useful still would have been a third squadron; that is, a navy half as large again as we then had. Expecting Cervera's force alone, a navy of such size, free from anxiety about coast defence, could have barred to him San Juan de Puerto Rico as well as Cienfuegos and Havana; or had Cámara been joined to Cervera, as he should have been, such a force would have closed both Cienfuegos and Havana with divisions that need not have feared the combined enemy. If, further, there had been a fourth squadron—our coast defence in each case remaining the same—our evident naval supremacy would probably have kept the Spanish fleet in Europe. Not unlikely there would have been no war; in which event, the anti-imperialist may observe there would, thanks to a great and prepared navy, have been no question of the Philippines, and possibly none of Hawaii.
In short, it is with coast defence and the navy as it is with numbers versus size in battleships. Both being necessary, the question of proportion demands close attention, but in both cases the same single principle dominates: offensive power, not defensive, determines the issues of war. In the solution of the problem, the extent to be given coast defence by fortification depends, as do all military decisions, whether of preparation or of actual warfare, upon certain well-recognized principles; and for a given country or coast, since the natural conditions remain permanent, the general dispositions, and the relative power of the several works, if determined by men of competent military knowledge, will remain practically constant during long periods. It is true, doubtless, that purely military conclusions must submit to some modification, in deference to the liability of a population to panics. The fact illustrates again the urgent necessity for the spread of sound elementary ideas on military subjects among the people at large; but, if the great coast cities are satisfied of their safety, a government will be able to resist the unreasonable clamor—for such it is—of small towns and villages, which are protected by their own insignificance. The navy is a more variable element; for the demands upon it depend upon external conditions of a political character, which may undergo changes not only sudden, but extensive. The results of the war with Spain, for instance, have affected but little the question of passive coast defence, by fortification or otherwise; but they have greatly altered the circumstances which hitherto have dictated the size of our active forces, both land and sea. Upon the greater or less strength of the navy depends, in a maritime conflict, the aggressive efficiency which shortens war, and so mitigates its evils. In the general question of preparation for naval war, therefore, the important centres and internal waterways of commerce must receive local protection, where they are exposed to attack from the sea; the rest must trust, and can in such case safely trust, to the fleet, upon which, as the offensive arm, all other expenditure for military maritime efficiency should be made. The preposterous and humiliating terrors of the past months, that a hostile fleet would waste coal and ammunition in shelling villages and bathers on a beach, we may hope will not recur.
Before proceeding to study the operations of the war, the military and naval conditions of the enemy at its outbreak must be briefly considered.
Spain, being a state that maintains at all times a regular army, respectable in numbers as well as in personal valor, had at the beginning, and, from the shortness of the war, continued to the end to have a decided land superiority over ourselves. Whatever we might hope eventually to produce in the way of an effective army, large enough for the work in Cuba, time was needed for the result, and time was not allowed. In one respect only the condition of the Peninsula seems to have resembled our own; that was in the inadequacy of the coast defences. The matter there was even more serious than with us, because not only were the preparations less, but several large sea-coast cities—for instance, Barcelona, Malaga, Cadiz—lie immediately upon the sea-shore; whereas most of ours are at the head of considerable estuaries, remote from the entrance. The exposure of important commercial
