The Interest of America in Sea Power, Present and Future. Alfred Thayer Mahan
to bewail Gibraltar. "I had rather see the English on the heights of Montmartre," said the first Napoleon, "than in Malta." The feelings of France about Egypt are matter of common knowledge, not even dissembled; and, for our warning be it added, her annoyance is increased by the bitter sense of opportunity rejected.
It is needless here to do more than refer to that other chain of maritime possessions—Halifax, Bermuda, Santa Lucia, Jamaica—which strengthen the British hold upon the Atlantic, the Caribbean, and the Isthmus of Panama. In the Pacific the position is for them much less satisfactory—nowhere, perhaps, is it less so, and from obvious natural causes. The commercial development of the eastern Pacific has been far later, and still is less complete, than that of its western shores. The latter when first opened to European adventure were already the seat of ancient economies in China and Japan, furnishing abundance of curious and luxurious products to tempt the trader by good hopes of profit. The western coast of America, for the most part peopled by savages, offered little save the gold and silver of Mexico and Peru, and these were monopolized jealously by the Spaniards—not a commercial nation—during their long ascendency. Being so very far from England and affording so little material for trade, Pacific America did not draw the enterprise of a country the chief and honorable inducement of whose seamen was the hope of gain, in pursuit of which they settled and annexed point after point in the regions where they penetrated, and upon the routes leading thither. The western coasts of North America, being reached only by the long and perilous voyage around Cape Horn, or by a more toilsome and dangerous passage across the continent, remained among the last of the temperate productive seaboards of the earth to be possessed by white men. The United States were already a nation, in fact as well as in form, when Vancouver was exploring Puget Sound and passed first through the channel separating the mainland of British America from the island which now bears his name. Thus it has happened that, from the late development of British Columbia in the northeastern Pacific, and of Australia and New Zealand in the southwestern, Great Britain is found again holding the two extremities of a line, between which she must inevitably desire the intermediate links; nor is there any good reason why she should not have them, except the superior, more urgent, more vital necessities of another people—our own. Of these links the Hawaiian group possesses unique importance—not from its intrinsic commercial value, but from its favorable position for maritime and military control.
The military or strategic value of a naval position depends upon its situation, upon its strength, and upon its resources. Of the three, the first is of most consequence, because it results from the nature of things; whereas the two latter, when deficient, can be supplied artificially, in whole or in part. Fortifications remedy the weaknesses of a position, foresight accumulates beforehand the resources which nature does not yield on the spot; but it is not within the power of man to change the geographical situation of a point which lies outside the limit of strategic effect. It is instructive, and yet apparent to the most superficial reading, to notice how the first Napoleon, in commenting upon a region likely to be the scene of war, begins by considering the most conspicuous natural features, and then enumerates the commanding positions, their distances from each other, the relative directions, or, as the sea phrase is, their "bearings," and the particular facilities each offers for operations of war. This furnishes the ground plan, the skeleton, detached from confusing secondary considerations, and from which a clear estimate of the decisive points can be made. The number of such points varies greatly, according to the character of the region. In a mountainous, broken country they may be very many; whereas in a plain devoid of natural obstacles there may be few, or none save those created by man. If few, the value of each is necessarily greater than if many; and if there be but one, its importance is not only unique, but extreme,—measured only by the size of the field over which its unshared influence extends.
The sea, until it approaches the land, realizes the ideal of a vast plain unbroken by obstacles. On the sea, says an eminent French tactician, there is no field of battle, meaning that there is none of the natural conditions which determine, and often fetter, the movements of the general. But upon a plain, however flat and monotonous, causes, possibly slight, determine the concentration of population into towns and villages, and the necessary communications between the centres create roads. Where the latter converge, or cross, tenure confers command, depending for importance upon the number of routes thus meeting, and upon their individual value. It is just so at sea. While in itself the ocean opposes no obstacle to a vessel taking any one of the numerous routes that can be traced upon the surface of the globe between two points, conditions of distance or convenience, of traffic or of wind, do prescribe certain usual courses. Where these pass near an ocean position, still more where they use it, it has an influence over them, and where several routes cross near by that influence becomes very great,—is commanding.
Let us now apply these considerations to the Hawaiian group. To any one viewing a map that shows the full extent of the Pacific Ocean, with its shores on either side, two striking circumstances will be apparent immediately. He will see at a glance that the Sandwich Islands stand by themselves, in a state of comparative isolation, amid a vast expanse of sea; and, again, that they form the centre of a large circle whose radius is approximately—and very closely—the distance from Honolulu to San Francisco. The circumference of this circle, if the trouble is taken to describe it with compass upon the map, will be seen, on the west and south, to pass through the outer fringe of the system of archipelagoes which, from Australia and New Zealand, extend to the northeast toward the American continent. Within the circle a few scattered islets, bare and unimportant, seem only to emphasize the failure of nature to bridge the interval separating Hawaii from her peers of the Southern Pacific. Of these, however, it may be noted that some, like Fanning and Christmas Islands, have within a few years been taken into British possession. The distance from San Francisco to Honolulu, twenty-one hundred miles—easy steaming distance—is substantially the same as that from Honolulu to the Gilbert, Marshall, Samoan, Society, and Marquesas groups, all under European control, except Samoa, in which we have a part influence.
To have a central position such as this, and to be alone, having no rival and admitting no alternative throughout an extensive tract, are conditions that at once fix the attention of the strategist,—it may be added, of the statesmen of commerce likewise. But to this striking combination are to be added the remarkable relations, borne by these singularly placed islands, to the greater commercial routes traversing this vast expanse known to us as the Pacific,—not only, however, to those now actually in use, important as they are, but also to those that must be called into being necessarily by that future to which the Hawaiian incident compels our too unwilling attention. Circumstances, as already remarked, create centres, between which communication necessarily follows; and in the vista of the future all discern, however dimly, a new and great centre that must largely modify existing sea routes, as well as bring new ones into existence. Whether the canal of the Central American isthmus be eventually at Panama or at Nicaragua matters little to the question now in hand, although, in common with most Americans who have thought upon the subject, I believe it surely will be at the latter point. Whichever it be, the convergence there of so many ships from the Atlantic and the Pacific will constitute a centre of commerce, interoceanic, and inferior to few, if to any, in the world; one whose approaches will be watched jealously, and whose relations to the other centres of the Pacific by the lines joining it to them must be examined carefully. Such study of the commercial routes and of their relations to the Hawaiian Islands, taken together with the other strategic considerations previously set forth, completes the synopsis of facts which determine the value of the group for conferring either commercial or naval control.
Referring again to the map, it will be seen that while the shortest routes from the Isthmus to Australia and New Zealand, as well as those to South America, go well clear of any probable connection with or interference from Hawaii, those directed toward China and Japan pass either through the group or in close proximity to it. Vessels from Central America bound to the ports of North America come, of course, within the influence of our own coast. These circumstances, and the existing recognized distribution of political power in the Pacific, point naturally to an international acquiescence in certain defined spheres of influence, for our own country and for others, such as has been reached already between Great Britain, Germany, and Holland in the Southwestern Pacific, to avoid conflict there between their respective claims. Though artificial in form, such a recognition, in the case here suggested, would depend upon perfectly natural
