He had, however, taken the precaution of dispatching a fast sailing brig to England with the news that the French fleet was returning to Europe. This ship, the "Curieux," actually got a glimpse of the enemy far off in mid ocean, and outsailed him to such good purpose that the Admiralty was able to order the squadrons blockading Brest and Rochefort to unite under the command of Sir Robert Calder and try to intercept Villeneuve on his way back. Though inferior in numbers to the allied fleet, Calder brought it to action in thick, foggy weather on 22 July, some ninety miles off the Spanish Cape Finisterre. The battle, fought in semi-darkness, was a desultory, indecisive encounter, and though Calder cut off and took two Spanish ships of the line, the feeling in England, when the news arrived, was not one of satisfaction at his partial success, but of undeserved indignation at his having failed to force the fighting and destroy the enemy's fleet. Villeneuve took his fleet into Vigo Bay. According to the plan of campaign, now that he had shaken off Nelson's pursuit, he should have sailed for the Channel, picking up the Brest and Rochefort squadrons on his way. Napoleon, at Boulogne, was ceaselessly drilling the Grand Army in rapid embarkation and disembarkation, and hoping each day for news of his admiral's dash into the Channel. But Villeneuve, who knew Keith had a squadron in the Channel, and had a vague dread of Nelson suddenly making his appearance, had a better appreciation of the small chance of the scheme giving any result than the imperious soldier-Emperor, who had come to believe that what he ordered must succeed. From Vigo, Villeneuve wrote to the Minister of Marine, Decrès, that his fleet was hardly in condition for any active enterprise. It had met with trying weather in the Atlantic. His flagship, the "Bucentaure," had been struck and damaged by lightning. All the ships needed a dockyard overhaul. There was sickness among the crews. He had to land hundreds of men and send them to hospital. He wanted recruits badly, and Vigo afforded only the scantiest resources for the refitting of the ships. He was already thinking of going back to Cadiz. He moved his fleet to Corunna, but there he found things in such a condition that he reported that he could not even find hospital room for the sick. From Napoleon came pressing orders to push on to the Channel at all risks. On 11 August Villeneuve put to sea, picking up a combined French and Spanish squadron from the neighbouring port of Ferrol. He meant to sail to Brest, bring out the squadron there, and call up the ships at Rochefort by sending on a frigate in advance with orders for that port. (The frigate was captured on the way by a British cruiser.) He sent a dispatch overland to Napoleon to say that at last he was coming.
