Upon this desultory principle, and seizing the opportunity of the blockading squadron being driven by weather from the vicinity of their harbour, a squadron of ten French vessels escaped from Rochefort on the 11th of January, 1805; and another, under Villeneuve, got out of Toulon on the 18th by a similarly favourable opportunity. The former, after rendering some trifling services in the West Indies, was fortunate enough to regain the port from which they had sailed, with the pride of a party who have sallied from a besieged town, and returned into it without loss. Villeneuve also regained Toulon without disaster, and, encouraged by his success, made a second sortie upon the 18th of March, having on board a large body of troops, designed, it was supposed, for a descent upon Ireland or Scotland. He made, however, towards Cadiz, and formed a junction there with the Spanish fleet under Gravina. They sailed for the West Indies, where the joint squadrons were able to possess themselves of a rock called Diamond, which is scarce to be discovered on the map; and with this trophy, which served at least to show they had been actually out of harbour, they returned with all speed to Europe. As for executing manœuvres, and forming combinations, as Napoleon's plans would lead us to infer was the purpose of their hurried expedition, they attempted none, save of that kind which the hare executes when the hound is at its heels. Nelson, they were aware, was in full pursuit of them, and to have attempted any thing which involved a delay, or gave a chance of his coming up with them, was to court destruction. They were so fortunate as to escape him, though very narrowly, yet did not reach their harbours in safety. On the 22d July, the combined fleets fell in with Sir Robert Calder, commanding a British squadron. The enemy amounted to twenty sail of the line, three fifty-gun ships, and four frigates, and the British to fifteen sail of the line, and two frigates only. Under this disparity of force, nevertheless, the English admiral defeated the enemy, and took two ships of the line; yet such was the opinion in both countries of the comparative superiority of the British navy, that the French considered their escape as a kind of triumph. Buonaparte alone grumbled against Villeneuve, for not having made use of his advantages,[183] for so it pleased him to term an engagement in which two ships of the line were lost; whilst the English murmured at the inadequate success of Sir Robert Calder, against an enemy of such superior strength, as if he had performed something less than his duty. A court-martial ratified, to a certain extent,[184] the popular opinion; though it may be doubted whether impartial posterity will concur in the justice of the censure which was passed upon the gallant admiral. At any other period of our naval history, the action of the 22d of July would have been rated as a distinguished victory.
