The Influence of Sea Power Upon History, 1660-1783. Alfred Thayer Mahan
on an element strange to most writers, as its members have been from time immemorial a strange race apart, without prophets of their own, neither themselves nor their calling understood, its immense determining influence upon the history of that era, and consequently upon the history of the world, has been overlooked. If the preceding argument is sound, it is as defective to omit sea power from the list of principal factors in the result, as it would be absurd to claim for it an exclusive influence.
Instances such as have been cited, drawn from widely separated periods of time, both before and after that specially treated in this work, serve to illustrate the intrinsic interest of the subject, and the character of the lessons which history has to teach. As before observed, these come more often under the head of strategy than of tactics; they bear rather upon the conduct of campaigns than of battles, and hence are fraught with more lasting value. To quote a great authority in this connection, Jomini says: "Happening to be in Paris near the end of 1851, a distinguished person did me the honor to ask my opinion as to whether recent improvements in firearms would cause any great modifications in the way of making war. I replied that they would probably have an influence upon the details of tactics, but that in great strategic operations and the grand combinations of battles, victory would, now as ever, result from the application of the principles which had led to the success of great generals in all ages; of Alexander and Cæsar, as well as of Frederick and Napoleon." This study has become more than ever important now to navies, because of the great and steady power of movement possessed by the modern steamer. The best-planned schemes might fail through stress of weather in the days of the galley and the sailing-ship; but this difficulty has almost disappeared. The principles which should direct great naval combinations have been applicable to all ages, and are deducible from history; but the power to carry them out with little regard to the weather is a recent gain.
The definitions usually given of the word "strategy" confine it to military combinations embracing one or more fields of operations, either wholly distinct or mutually dependent, but always regarded as actual or immediate scenes of war. However this may be on shore, a recent French author is quite right in pointing out that such a definition is too narrow for naval strategy. "This," he says, "differs from military strategy in that it is as necessary in peace as in war. Indeed, in peace it may gain its most decisive victories by occupying in a country, either by purchase or treaty, excellent positions which would perhaps hardly be got by war. It learns to profit by all opportunities of settling on some chosen point of a coast, and to render definitive an occupation which at first was only transient." A generation that has seen England within ten years occupy successively Cyprus and Egypt, under terms and conditions on their face transient, but which have not yet led to the abandonment of the positions taken, can readily agree with this remark; which indeed receives constant illustration from the quiet persistency with which all the great sea powers are seeking position after position, less noted and less noteworthy than Cyprus and Egypt, in the different seas to which their people and their ships penetrate. "Naval strategy has indeed for its end to found, support, and increase, as well in peace as in war, the sea power of a country;" and therefore its study has an interest and value for all citizens of a free country, but especially for those who are charged with its foreign and military relations.
The general conditions that either are essential to or powerfully affect the greatness of a nation upon the sea will now be examined; after which a more particular consideration of the various maritime nations of Europe at the middle of the seventeenth century, where the historical survey begins, will serve at once to illustrate and give precision to the conclusions upon the general subject.
Note.—The brilliancy of Nelson's fame, dimming as it does that of all his contemporaries, and the implicit trust felt by England in him as the one man able to save her from the schemes of Napoleon, should not of course obscure the fact that only one portion of the field was, or could be, occupied by him. Napoleon's aim, in the campaign which ended at Trafalgar, was to unite in the West Indies the French fleets of Brest, Toulon, and Rochefort, together with a strong body of Spanish ships, thus forming an overwhelming force which he intended should return together to the English Channel and cover the crossing of the French army. He naturally expected that, with England's interests scattered all over the world, confusion and distraction would arise from ignorance of the destination of the French squadrons, and the English navy be drawn away from his objective point. The portion of the field committed to Nelson was the Mediterranean, where he watched the great arsenal of Toulon and the highways alike to the East and to the Atlantic. This was inferior in consequence to no other, and assumed additional importance in the eyes of Nelson from his conviction that the former attempts on Egypt would be renewed. Owing to this persuasion he took at first a false step, which delayed his pursuit of the Toulon fleet when it sailed under the command of Villeneuve; and the latter was further favored by a long continuance of fair winds, while the English had head winds. But while all this is true, while the failure of Napoleon's combinations must be attributed to the tenacious grip of the English blockade off Brest, as well as to Nelson's energetic pursuit of the Toulon fleet when it escaped to the West Indies and again on its hasty return to Europe, the latter is fairly entitled to the eminent distinction which history has accorded it, and which is asserted in the text. Nelson did not, indeed, fathom the intentions of Napoleon. This may have been owing, as some have said, to lack of insight; but it may be more simply laid to the usual disadvantage under which the defence lies before the blow has fallen, of ignorance as to the point threatened by the offence. It is insight enough to fasten on the key of a situation; and this Nelson rightly saw was the fleet, not the station. Consequently, his action has afforded a striking instance of how tenacity of purpose and untiring energy in execution can repair a first mistake and baffle deeply laid plans. His Mediterranean command embraced many duties and cares; but amid and dominating them all, he saw clearly the Toulon fleet as the controlling factor there, and an important factor in any naval combination of the Emperor. Hence his attention was unwaveringly fixed upon it; so much so that he called it "his fleet," a phrase which has somewhat vexed the sensibilities of French critics. This simple and accurate view of the military situation strengthened him in taking the fearless resolution and bearing the immense responsibility of abandoning his station in order to follow "his fleet." Determined thus on a pursuit the undeniable wisdom of which should not obscure the greatness of mind that undertook it, he followed so vigorously as to reach Cadiz on his return a week before Villeneuve entered Ferrol, despite unavoidable delays arising from false information and uncertainty as to the enemy's movements. The same untiring ardor enabled him to bring up his own ships from Cadiz to Brest in time to make the fleet there superior to Villeneuve's, had the latter persisted in his attempt to reach the neighborhood. The English, very inferior in aggregate number of vessels to the allied fleets, were by this seasonable reinforcement of eight veteran ships put into the best possible position strategically, as will be pointed out in dealing with similar conditions in the war of the American Revolution. Their forces were united in one great fleet in the Bay of Biscay, interposed between the two divisions of the enemy in Brest and Ferrol, superior in number to either singly, and with a strong probability of being able to deal with one before the other could come up. This was due to able action all round on the part of the English authorities; but above all other factors in the result stands Nelson's single-minded pursuit of "his fleet."
This interesting series of strategic movements ended on the 14th of August, when Villeneuve, in despair of reaching Brest, headed for Cadiz, where he anchored on the 20th. As soon as Napoleon heard of this, after an outburst of rage against the admiral, he at once dictated the series of movements which resulted in Ulm and Austerlitz, abandoning his purposes against England. The battle of Trafalgar, fought October 21, was therefore separated by a space of two months from the extensive movements of which it was nevertheless the outcome. Isolated from them in point of time, it was none the less the seal of Nelson's genius, affixed later to the record he had made in the near past. With equal truth it is said that England was saved at Trafalgar, though the Emperor had then given up his intended invasion; the destruction there emphasized and sealed the strategic triumph which had noiselessly foiled Napoleon's plans.
CHAPTER I
The first and most obvious light in which the sea presents itself from the political and social point of view is that of a great highway; or better, perhaps, of a wide common, over which men may pass in all directions,
