[The origin of the ensuing article was as follows: At the time of the Revolution in Hawaii, at the beginning of 1893, the author addressed to the "New York Times" a letter, which appeared in the issue of January 31. This, falling under the eye of the Editor of the "Forum," suggested to him to ask an article upon the general military—or naval—value of the Hawaiian group. The letter alluded to ran thus:—

To the Editor of the "New York Times":—

There is one aspect of the recent revolution in Hawaii which seems to have been kept out of sight, and that is the relation of the islands, not merely to our own and to European countries, but to China. How vitally important that may become in the future is evident from the great number of Chinese, relatively to the whole population, now settled in the islands.

It is a question for the whole civilized world and not for the United States only, whether the Sandwich Islands, with their geographical and military importance, unrivalled by that of any other position in the North Pacific, shall in the future be an outpost of European civilization, or of the comparative barbarism of China. It is sufficiently known, but not, perhaps, generally noted in our country, that many military men abroad, familiar with Eastern conditions and character, look with apprehension toward the day when the vast mass of China—now inert—may yield to one of those impulses which have in past ages buried civilization under a wave of barbaric invasion. The great armies of Europe, whose existence is so frequently deplored, may be providentially intended as a barrier to that great movement, if it come. Certainly, while China remains as she is, nothing more disastrous for the future of the world can be imagined than that general disarmament of Europe which is the Utopian dream of some philanthropists.

China, however, may burst her barriers eastward as well as westward, toward the Pacific as well as toward the European Continent. In such a movement it would be impossible to exaggerate the momentous issues dependent upon a firm hold of the Sandwich Islands by a great, civilized, maritime power. By its nearness to the scene, and by the determined animosity to the Chinese movement which close contact seems to inspire, our own country, with its Pacific coast, is naturally indicated as the proper guardian for this most important position. To hold it, however, whether in the supposed case or in war with a European state, implies a great extension of our naval power. Are we ready to undertake this?

A.T. MAHAN, Captain, United States Navy .

NEW YORK, Jan. 30, 1893.]

The suddenness—so far, at least, as the general public is concerned—with which the long-existing troubles in Hawaii have come to a head, and the character of the advances reported to be addressed to the United States by the revolutionary government, formally recognized as de facto by our representative on the spot, add another to the many significant instances furnished by history, that, as men in the midst of life are in death, so nations in the midst of peace find themselves confronted with unexpected causes of dissension, conflicts of interests, whose results may be, on the one hand, war, or, on the other, abandonment of clear and imperative national advantage in order to avoid an issue for which preparation has not been made. By no premeditated contrivance of our own, by the cooperation of a series of events which, however dependent step by step upon human action, were not intended to prepare the present crisis, the United States finds herself compelled to answer a question—to make a decision—not unlike and not less momentous than that required of the Roman senate, when the Mamertine garrison invited it to occupy Messina, and so to abandon the hitherto traditional policy which had confined the expansion of Rome to the Italian peninsula. For let it not be overlooked that, whether we wish or no, we must answer the question, we must make the decision. The issue cannot be dodged. Absolute inaction in such a case is a decision as truly as the most vehement action. We can now advance, but, the conditions of the world being what they are, if we do not advance we recede; for there is involved not so much a particular action as a question of principle, pregnant of great consequences in one direction or in the other.

Occasion of serious difficulty, indeed, should not arise here. Unlike the historical instance just cited, the two nations whose interests have come now into contact—Great Britain and the United States—are so alike in inherited traditions, habits of thought, and views of right, that injury to the one need not be anticipated from the predominance of the other in a quarter where its interests also predominate. Despite the heterogeneous character of the immigration which the past few years have been pouring into our country, our political traditions and racial characteristics still continue English—Mr. Douglas Campbell would say Dutch, but even so the stock is the same. Though thus somewhat gorged with food not wholly to its taste, our political digestion has contrived so far to master the incongruous mass of materials it has been unable to reject; and if assimilation has been at times imperfect, our political constitution and spirit remain English in essential features. Imbued with like ideals of liberty, of law, of right, certainly not less progressive than our kin beyond sea, we are, in the safeguards deliberately placed around our fundamental law, even more conservative than they. That which we received of the true spirit of freedom we have kept—liberty and law—not the one or the other, but both. In that spirit we not only have occupied our original inheritance, but also, step by step, as Rome incorporated the other nations of the peninsula, we have added to it, spreading and perpetuating everywhere the same foundation principles of free and good government which, to her honor be it said, Great Britain also has maintained throughout her course. And now, arrested on the south by the rights of a race wholly alien to us, and on the north by a body of states of like traditions to our own, whose freedom to choose their own affiliations we respect, we have come to the sea. In our infancy we bordered upon the Atlantic only; our youth carried our boundary to the Gulf of Mexico; to-day maturity sees us upon the Pacific. Have we no right or no call to progress farther in any direction? Are there for us beyond the sea horizon none of those essential interests, of those evident dangers, which impose a policy and confer rights?

This is the question that long has been looming upon the brow of a future now rapidly passing into the present. Of it the Hawaiian incident is a part—intrinsically, perhaps, a small part—but in its relations to the whole so vital that, as has been said before, a wrong decision does not stand by itself, but involves, not only in principle but in fact, recession along the whole line. In our natural, necessary, irrepressible expansion, we are come here into contact with the progress of another great people, the law of whose being has impressed upon it a principle of growth which has wrought mightily in the past, and in the present is visible by recurring manifestations. Of this working, Gibraltar, Malta, Cyprus, Egypt, Aden, India, in geographical succession though not in strict order of time, show a completed chain; forged link by link, by open force or politic bargain, but always resulting from the steady pressure of a national instinct, so powerful and so accurate that statesmen of every school, willing or unwilling, have found themselves carried along by a tendency which no individuality can resist or greatly modify. Both unsubstantial rumor and incautious personal utterance have suggested an impatient desire in Mr. Gladstone to be rid of the occupation of Egypt; but scarcely has his long exclusion from office ended when the irony of events signalizes his return thereto by an increase in the force of occupation. Further, it may be noted profitably of the chain just cited, that the two extremities were first possessed—first India, then Gibraltar, far later Malta, Aden, Cyprus, Egypt—and that, with scarce an exception, each step has been taken despite the jealous vexation of a rival. Spain has never ceased angrily 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 as well as indisputable conditions. The United States is by far the greatest, in numbers, interests, and power, of the communities bordering upon the eastern shores of the North Pacific; and the relations of the Hawaiian Islands to her naturally would be, and actually are, more numerous and more important than they can be to any other state. This is true, although, unfortunately for the equally natural wishes of Great Britain and her colonies, the direct routes from British Columbia to Eastern Australia and New Zealand, which depend upon no building of a future canal, pass as near the islands as those already mentioned. Such a fact, that this additional great highway runs close to the group, both augments and emphasizes their strategic importance; but it does not affect the statement just made, that the interest of the United States in them surpasses that of Great Britain, and dependent upon a natural cause, nearness, which has been admitted always as a reasonable ground for national self-assertion. It is unfortunate, doubtless, for the wishes of British Columbia, and for the communications, commercial and military, depending upon the Canadian Pacific Railway, that the United States lies between them and the South Pacific, and is the state nearest to Hawaii; but, the fact being so, the interests of our sixty-five million people, in a position so vital to our part in the Pacific, must be allowed to outweigh those of the six millions of Canada.

From the foregoing considerations may be inferred the importance of the Hawaiian Islands as a position powerfully influencing the commercial and military control of the Pacific, and especially of the Northern Pacific, in which the United States, geographically, has the strongest right to assert herself. These are the main advantages, which can be termed positive: those, namely, which directly advance commercial security and naval control. To the negative advantages of possession, by removing conditions which, if the islands were in the hands of any other power, would constitute to us disadvantages and threats, allusion only will be made. The serious menace to our Pacific coast and our Pacific trade, if so important a position were held by a possible enemy, has been mentioned frequently in the press, and dwelt upon in the diplomatic papers which from time to time are given to the public. It may be assumed that it is generally acknowledged. Upon one particular, however, too much stress cannot be laid, one to which naval officers cannot but be more sensitive than the general public, and that is the immense disadvantage to us of any maritime enemy having a coaling-station well within twenty-five hundred miles, as this is, of every point of our coast-line from Puget Sound to Mexico. Were there many others available, we might find it difficult to exclude from all. There is, however, but the one. Shut out from the Sandwich Islands as a coal base, an enemy is thrown back for supplies of fuel to distances of thirty-five hundred or four thousand miles,—or between seven thousand and eight thousand, going and coming,—an impediment to sustained maritime operations well-nigh prohibitive. The coal-mines of British Columbia constitute, of course, a qualification to this statement; but upon them, if need arose, we might hope at least to impose some trammels by action from the land side. It is rarely that so important a factor in the attack or defence of a coast-line—of a sea frontier—is concentrated in a single position; and the circumstance renders doubly imperative upon us to secure it, if we righteously can.

It is to be hoped, also, that the opportunity thus thrust upon us may not be viewed narrowly, as though it concerned but one section of our country or one portion of its external trade or influence. This is no mere question of a particular act, for which, possibly, just occasion may not have offered yet; but of a principle, a policy, fruitful of many future acts, to enter upon which, in the fulness of our national progress, the time now has arrived. The principle being accepted, to be conditioned only by a just and candid regard for the rights and reasonable susceptibilities of other nations,—none of which is contravened by the step here immediately under discussion,—the annexation, even, of Hawaii would be no mere sporadic effort, irrational because disconnected from an adequate motive, but a first-fruit and a token that the nation in its evolution has aroused itself to the necessity of carrying its life—that has been the happiness of those under its influence—beyond the borders which heretofore have sufficed for its activities. That the vaunted blessings of our economy are not to be forced upon the unwilling may be conceded; but the concession does not deny the right nor the wisdom of gathering in those who wish to come. Comparative religion teaches that creeds which reject missionary enterprise are foredoomed to decay. May it not be so with nations? Certainly the glorious record of England is consequent mainly upon the spirit, and traceable to the time, when she launched out into the deep—without formulated policy, it is true, or foreseeing the future to which her star was leading, but obeying the instinct which in the infancy of nations anticipates the more reasoned impulses of experience. Let us, too, learn from her experience. Not all at once did England become the great sea power which she is, but step by step, as opportunity offered, she has moved on to the world-wide pre-eminence now held by English speech, and by institutions sprung from English germs. How much poorer would the world have been, had Englishmen heeded the cautious hesitancy that now bids us reject every advance beyond our shore-lines! And can any one doubt that a cordial, if unformulated, understanding between the two chief states of English tradition, to spread freely, without mutual jealousy and in mutual support, would increase greatly the world's sum of happiness?

But if a plea of the world's welfare seem suspiciously like a cloak for national self-interest, let the latter be accepted frankly as the adequate motive which it assuredly is. Let us not shrink from pitting a broad self-interest against the narrow self-interest to which some would restrict us. The demands of our three great seaboards, the Atlantic, the Gulf, and the Pacific,—each for itself, and all for the strength that comes from drawing closer the ties between them,—are calling for the extension, through the Isthmian Canal, of that broad sea common along which, and along which alone, in all the ages prosperity has moved. Land carriage, always restricted and therefore always slow, toils enviously but hopelessly behind, vainly seeking to replace and supplant the royal highway of nature's own making. Corporate interests, vigorous in that power of concentration which is the strength of armies and of minorities, may here withstand for a while the ill-organized strivings of the multitude, only dimly conscious of its wants; yet the latter, however temporarily opposed and baffled, is sure at last, like the blind forces of nature, to overwhelm all that stand in the way of its necessary progress. So the Isthmian Canal is an inevitable part in the future of the United States; yet one that cannot be separated from other necessary incidents of a policy dependent upon it, whose details cannot be foreseen exactly. But because the precise steps that hereafter may be opportune or necessary cannot yet be foretold certainly, is not a reason the less, but a reason the more, for establishing a principle of action which may serve to guide as opportunities arise. Let us start from the fundamental truth, warranted by history, that the control of the seas, and especially along the great lines drawn by national interest or national commerce, is the chief among the merely material elements in the power and prosperity of nations. It is so because the sea is the world's great medium of circulation. From this necessarily follows the principle that, as subsidiary to such control, it is imperative to take possession, when it can be done righteously, of such maritime positions as contribute to secure command. If this principle be adopted, there will be no hesitation about taking the positions—and they are many—upon the approaches to the Isthmus, whose interests incline them to seek us. It has its application also to the present case of Hawaii.

There is, however, one caution to be given from the military point of view, beyond the need of which the world has not yet passed. Military positions, fortified posts, by land or by sea, however strong or admirably situated, do not confer control by themselves alone. People often say that such an island or harbor will give control of such a body of water. It is an utter, deplorable, ruinous mistake. The phrase indeed may be used by some only loosely, without forgetting other implied conditions of adequate protection and adequate navies; but the confidence of our own nation in its native strength, and its indifference to the defence of its ports and the sufficiency of its fleet, give reason to fear that the full consequences of a forward step may not be weighed soberly. Napoleon, who knew better, once talked this way. "The islands of San Pietro, Corfu, and Malta," he wrote, "will make us masters of the whole Mediterranean." Vain boast! Within one year Corfu, in two years Malta, were rent away from the state that could not support them by its ships. Nay, more: had Bonaparte not taken the latter stronghold out of the hands of its degenerate but innocuous government, that citadel of the Mediterranean would perhaps—would probably—never have passed into those of his chief enemy. There is here also a lesson for us.

It is by no means logical to leap, from this recognition of the necessity of adequate naval force to secure outlying dependencies, to the conclusion that the United States would need for that object a navy equal to the largest now existing. A nation as far removed as is our own from the bases of foreign naval strength may reasonably reckon upon the qualification that distance—not to speak of the complex European interests close at hand—impresses upon the exertion of naval strength by European powers. The mistake is when our remoteness, unsupported by carefully calculated force, is regarded as an armor of proof, under cover of which any amount of swagger may be indulged safely. An estimate of what is an adequate naval force for our country may properly take into account the happy interval which separates both our present territory and our future aspirations from the centres of interest really vital to European states. If to these safeguards be added, on our part, a sober recognition of what our reasonable sphere of influence is, and a candid justice in dealing with foreign interests within that sphere, there will be little disposition to question our preponderance therein.

Among all foreign states, it is especially to be hoped that each passing year may render more cordial the relations between ourselves and the great nation from whose loins we sprang. The radical identity of spirit which underlies our superficial differences of polity surely will draw us closer together, if we do not set our faces wilfully against a tendency which would give our race the predominance over the seas of the world. To force such a consummation is impossible, and if possible would not be wise; but surely it would be a lofty aim, fraught with immeasurable benefits, to desire it, and to raise no needless impediments by advocating perfectly proper acts, demanded by our evident interests, in offensive or arrogant terms.
