If such a chase follow a battle, it can scarcely fail that the weaker party—the retreating party—is also distressed by crippled ships, which he may be forced to abandon—or fight. Strenuous, unrelaxing pursuit is therefore as imperative after a battle as is courage during it. Great political results often flow from correct military action; a fact which no military commander is at liberty to ignore. He may very well not know of those results; it is enough to know that they may happen, and nothing can excuse his losing a point which by exertion he might have scored. Napoleon, says Jomini, never forgave the general who in 1796, by resting his troops a couple of hours, failed to get between an Austrian division and Mantua, in which it was seeking refuge, and by his neglect found it. The failure of Admiral de Tourville to pursue vigorously the defeated Dutch and English fleet, after the battle of Beachy Head, in 1690, caused that victory to be indecisive, and helped to fasten the crown of England on the head of a Dutch King, who was the soul of the alliance against France. Slackness in following up victory had thus a decisive influence upon the results of the whole war, both on the continent and the sea. I may add, it has proved injurious to the art of naval strategy, by the seeming confirmation it has given to the theory of the “fleet in being.” It was not the beaten and crippled English and Dutch “fleet in being” that prevented an invasion of England. It was the weakness or inertness of Tourville, or the unreadiness of the French transports. Similarly, the refusal of Admiral Hotham to pursue vigorously a beaten French fleet in 1795, unquestionably not only made that year’s campaign indecisive, but made possible Napoleon’s Italian campaign of 1796, from which flowed his whole career and its effects upon history. The same dazzling career received its sudden mortal stab when, in the height of his crushing advance in Spain, with its capital in his hands, at the very moment when his vast plans seemed on the eve of accomplishment, a more enterprising British leader, Sir John Moore, moved his petty army to Sahagun, on the flank of Napoleon’s communications between France and Madrid. The blow recoiled upon Moore, who was swept as by a whirlwind to Coruña, and into the sea; but Spain was saved. The Emperor could not retrieve the lost time and opportunity. He could not return to Madrid in person, but had to entrust to several subordinates the task which only his own supreme genius could successfully supervise. From the military standpoint, his downfall dates from that day. The whole career of Wellington, to Waterloo, lay in the womb of Moore’s daring conception. But for that, wrote Napier, the Peninsular War would not have required a chronicler.
