On the 14th of September, before quitting Paris, Napoleon sent Villeneuve orders to take the first favorable opportunity to leave Cadiz, to enter the Mediterranean, join the ships at Cartagena, and with this combined force move upon southern Italy. There, at any suitable point, he was to land the troops embarked in the fleet to reinforce General St. Cyr, who already had instructions to be ready to attack Naples at a moment’s notice.[78] The next day these orders were reiterated to Decrès, enforcing the importance to the general campaign of so powerful a diversion as the presence of this great fleet in the Mediterranean; but, as “Villeneuve’s excessive pusillanimity will prevent him from undertaking this, you will send to replace him Admiral Rosily, who will bear letters directing Villeneuve to return to France and give an account of his conduct.”[79] The emperor had already formulated his complaints against the admiral under seven distinct heads.[80] On the 15th of September, the same day the orders to relieve Villeneuve were issued, Nelson, having spent at home only twenty-five days, left England for the last time. On the 28th, when he joined the fleet off Cadiz, he found under his command twenty-nine ships-of-the-line, which successive arrivals raised to thirty-three by the day of the battle; but, water running short, it became necessary to send the ships, by divisions of six, to fill up at Gibraltar. To this cause was due that only twenty-seven British vessels were present in the action,—an unfortunate circumstance; for, as Nelson said, what the country wanted was not merely a splendid victory, but annihilation; “numbers only can annihilate.”[81] The force under his command was thus disposed: the main body about fifty miles west-south-west of Cadiz, seven lookout frigates close in with the port, and between these extremes, two small detachments of ships-of-the-line,—the one twenty miles from the harbor, the other about thirty-five. “By this chain,” he wrote, “I hope to have constant communication with the frigates.” “_The Nelson Touch_”[82]
