successfully evaded Nelson's when the British were blown off station by storms. Nelson commenced a search of the Mediterranean, supposing that the French intended to make for Egypt, but Villeneuve instead took his fleet through the Strait of Gibraltar, rendezvoused with the Spanish fleet in Cádiz, and sailed as planned for the Caribbean. Once Nelson realised that the French were crossing the Atlantic Ocean, he set off in pursuit. He missed them by just days in the West Indies as a result of false information. Cádiz Having lured the British to the West Indies Villeneuve returned from the Caribbean to Europe, intending to break the blockade at Brest. Nelson, still in fear for Egypt, made to return to the Mediterranean. The fast sailing corvette taking word of his plans back to the admiralty spotted the French heading further north. On receiving this intelligence Lord Barham was alive to the enemy strategy and immediately ordered Admiral William Cornwallis to combine his squadron with that of Vice Admiral Sir Robert Calder off Ferrol and to stretch out thirty to forty leagues into the Atlantic to block the French from entering the Channel. Calder intercepted the French resulting in an inconclusive engagement during the Battle of Cape Finisterre in which two of the Spanish ships were captured. Villeneuve abandoned his plan and sailed back to Ferrol in northern Spain. There he received orders from Napoleon to return to Brest according to the main plan. Napoleon's invasion plans for Britain depended on having a sufficiently large number of ships of the line before Boulogne in France. This would require Villeneuve's force of 33 ships to join Vice-Admiral Ganteaume's force of 21 ships at Brest, along with a squadron of five ships under Captain Allemand, which would have given him a combined force of 59 ships of the line. When Villeneuve set sail from Ferrol on 10 August, he was under orders from Napoleon to sail northward toward Brest. Instead, he worried that the British were observing his manoeuvres, so on 11 August, he sailed southward towards Cádiz on the southwestern coast of Spain. With no sign of Villeneuve's fleet, on 25 August, the three French army corps' invasion force near Boulogne broke camp and marched into Germany, where it was later engaged. This ended the immediate threat of invasion. The same month, Admiral Lord Nelson returned home to Britain after two years of duty
