The Influence of Sea Power Upon History, 1660-1783. Alfred Thayer Mahan
a nation, fitting out privateers without direct expense to the State, possesses the specious attractions which economy always presents. The great injury done to the wealth and prosperity of the enemy is also undeniable; and although to some extent his merchant-ships can shelter themselves ignobly under a foreign flag while the war lasts, this guerre de course, as the French call it, this commerce-destroying, to use our own phrase, must, if in itself successful, greatly embarrass the foreign government and distress its people. Such a war, however, cannot stand alone; it must be supported, to use the military phrase; unsubstantial and evanescent in itself, it cannot reach far from its base. That base must be either home ports, or else some solid outpost of the national power, on the shore or the sea; a distant dependency or a powerful fleet. Failing such support, the cruiser can only dash out hurriedly a short distance from home, and its blows, though painful, cannot be fatal. It was not the policy of 1667, but Cromwell's powerful fleets of ships-of-the-line in 1652, that shut the Dutch merchantmen in their ports and caused the grass to grow in the streets of Amsterdam. When, instructed by the suffering of that time, the Dutch kept large fleets afloat through two exhausting wars, though their commerce suffered greatly, they bore up the burden of the strife against England and France united. Forty years later, Louis XIV. was driven, by exhaustion, to the policy adopted by Charles II. through parsimony. Then were the days of the great French privateers, Jean Bart, Forbin, Duguay-Trouin, Du Casse, and others. The regular fleets of the French navy were practically withdrawn from the ocean during the great War of the Spanish Succession (1702-1712). The French naval historian says:—
"Unable to renew the naval armaments, Louis XIV. increased the number of cruisers upon the more frequented seas, especially the Channel and the German Ocean [not far from home, it will be noticed]. In these different spots the cruisers were always in a position to intercept or hinder the movements of transports laden with troops, and of the numerous convoys carrying supplies of all kinds. In these seas, in the centre of the commercial and political world, there is always work for cruisers. Notwithstanding the difficulties they met, owing to the absence of large friendly fleets, they served advantageously the cause of the two peoples [French and Spanish]. These cruisers, in the face of the Anglo-Dutch power, needed good luck, boldness, and skill. These three conditions were not lacking to our seamen; but then, what chiefs and what captains they had!"39
The English historian, on the other hand, while admitting how severely the people and commerce of England suffered from the cruisers, bitterly reflecting at times upon the administration, yet refers over and over again to the increasing prosperity of the whole country, and especially of its commercial part. In the preceding war, on the contrary, from 1689 to 1697, when France sent great fleets to sea and disputed the supremacy of the ocean, how different the result! The same English writer says of that time:—
"With respect to our trade it is certain that we suffered infinitely more, not merely than the French, for that was to be expected from the greater number of our merchant-ships, but than we ever did in any former war.... This proceeded in great measure from the vigilance of the French, who carried on the war in a piratical way. It is out of all doubt that, taking all together, our traffic suffered excessively; our merchants were many of them ruined."40
Macaulay says of this period: "During many months of 1693 the English trade with the Mediterranean had been interrupted almost entirely. There was no chance that a merchantman from London or Amsterdam would, if unprotected, reach the Pillars of Hercules without being boarded by a French privateer; and the protection of armed vessels was not easily obtained." Why? Because the vessels of England's navy were occupied watching the French navy, and this diversion of them from the cruisers and privateers constituted the support which a commerce-destroying war must have. A French historian, speaking of the same period in England (1696), says: "The state of the finances was deplorable; money was scarce, maritime insurance thirty per cent, the Navigation Act was virtually suspended, and the English shipping reduced to the necessity of sailing under the Swedish and Danish flags."41 Half a century later the French government was again reduced, by long neglect of the navy, to a cruising warfare. With what results? First, the French historian says: "From June, 1756, to June, 1760, French privateers captured from the English more than twenty-five hundred merchantmen. In 1761, though France had not, so to speak, a single ship-of-the-line at sea, and though the English had taken two hundred and forty of our privateers, their comrades still took eight hundred and twelve vessels. But," he goes on to say, "the prodigious growth of the English shipping explains the number of these prizes."42 In other words, the suffering involved to England in such numerous captures, which must have caused great individual injury and discontent, did not really prevent the growing prosperity of the State and of the community at large. The English naval historian, speaking of the same period, says: "While the commerce of France was nearly destroyed, the trading-fleet of England covered the seas. Every year her commerce was increasing; the money which the war carried out was returned by the produce of her industry. Eight thousand merchant vessels were employed by the English merchants." And again, summing up the results of the war, after stating the immense amount of specie brought into the kingdom by foreign conquests, he says: "The trade of England increased gradually every year, and such a scene of national prosperity, while waging a long, bloody, and costly war, was never before shown by any people in the world." On the other hand, the historian of the French navy, speaking of an earlier phase of the same wars, says: "The English fleets, having nothing to resist them, swept the seas. Our privateers and single cruisers, having no fleet to keep down the abundance of their enemies, ran short careers. Twenty thousand French seamen lay in English prisons."43 When, on the other hand, in the War of the American Revolution France resumed the policy of Colbert and of the early reign of Louis XIV., and kept large battle-fleets afloat, the same result again followed as in the days of Tourville. "For the first time," says the Annual Register, forgetting or ignorant of the experience of 1693, and remembering only the glories of the later wars, "English merchant-ships were driven to take refuge under foreign flags."44 Finally, in quitting this part of the subject, it may be remarked that in the island of Martinique the French had a powerful distant dependency upon which to base a cruising warfare; and during the Seven Years' War, as afterward during the First Empire, it, with Guadeloupe, was the refuge of numerous privateers. "The records of the English admiralty raise the losses of the English in the West Indies during the first years of the Seven Years' War to fourteen hundred merchantmen taken or destroyed." The English fleet was therefore directed against the islands, both of which fell, involving a loss to the trade of France greater than all the depredations of her cruisers on the English commerce, besides breaking up the system; but in the war of 1778 the great fleets protected the islands, which were not even threatened at any time.
So far we have been viewing the effect of a purely cruising warfare, not based upon powerful squadrons, only upon that particular part of the enemy's strength against which it is theoretically directed,—upon his commerce and general wealth; upon the sinews of war. The evidence seems to show that even for its own special ends such a mode of war is inconclusive, worrying but not deadly; it might almost be said that it causes needless suffering. What, however, is the effect of this policy upon the general ends of the war, to which it is one of the means, and to which it is subsidiary? How, again, does it react upon the people that practise it? As the historical evidences will come up in detail from time to time, it need here only be summarized. The result to England in the days of Charles II. has been seen,—her coast insulted, her shipping burned almost within sight of her capital. In the War of the Spanish Succession, when the control of Spain was the military object, while the French depended upon a cruising war against commerce, the navies of England and Holland, unopposed, guarded the coasts of the peninsula, blocked the port of Toulon, forced the French succors to cross the Pyrenees, and by keeping open the sea highway, neutralized the geographical nearness of France to the seat of war. Their fleets seized Gibraltar, Barcelona, and Minorca, and co-operating with the Austrian army failed by little of reducing Toulon. In the Seven Years' War the English fleets seized, or aided in seizing, all the most valuable colonies of France and Spain, and made frequent descents on the French coast.
