Such, in its leading outlines and direct consequences, was the famous battle of Trafalgar. Its lasting significance and far-reaching results have been well stated by a recent historian, more keenly alive than most of his fellows to the paramount, though silent, influence of Sea Power upon the course of events: “Trafalgar was not only the greatest naval victory, it was the greatest and most momentous victory won either by land or by sea during the whole of the Revolutionary War. No victory, and no series of victories, of Napoleon produced the same effect upon Europe.... A generation passed after Trafalgar before France again seriously threatened England at sea. The prospect of crushing the British navy, so long as England had the means to equip a navy, vanished. Napoleon henceforth set his hopes on exhausting England’s resources, by compelling every state on the Continent to exclude her commerce. Trafalgar forced him to impose his yoke upon _all_ Europe, or to abandon the hope of conquering Great Britain.... Nelson’s last triumph left England in such a position that no means remained to injure her but those which _must result in the ultimate deliverance of the Continent_.”[85] These words may be accepted with very slight modification. Napoleon’s scheme for the invasion of Great Britain, thwarted once and again by the strategic difficulties attendant upon its execution, was finally frustrated when Villeneuve gave up the attempt to reach Brest and headed for Cadiz. On the part of the allies Trafalgar was, in itself, a useless holocaust, precipitated in the end by the despair of the unfortunate admiral, upon whose irresolution Napoleon not unjustly visited the anger caused by the wreck of his plans. Villeneuve was perfectly clear-sighted and right in his appreciation of the deficiencies of his command,—of the many chances against success. Where he wretchedly failed was in not recognizing the simple duty of obedience,—the obligation to persist at all hazards in the part of a great scheme assigned to him, even though it led to the destruction of his whole force. Had he, upon leaving Ferrol, been visited by a little of the desperation which brought him to Trafalgar, the invasion of England might possibly—not probably—have been effected. An event so striking as the battle of Trafalgar becomes, however, to mankind the symbol of all the circumstances—more important, perhaps, but less obvious—which culminate in it. In this sense it may be said that Trafalgar was the cause—as it certainly marked the period—of Napoleon’s resolution to crush Great Britain by excluding her commerce from the Continent. Here, therefore, the story of the influence of Sea Power upon this great conflict ceases to follow the strictly naval events, and becomes concerned simply with commerce-destroying, ordinarily a secondary operation of maritime war, but exalted in the later years of Napoleon’s reign to be the principal, if not the sole, means of action.
