Villeneuve's fleet underwent repairs in Cádiz, covered by a hastily assembled blockade of British warships, initially commanded by Rear-Admiral Cuthbert Collingwood, and from 27 September by Vice-Admiral Nelson, who had arrived from England to take command. He spent the following weeks preparing and refining his tactics for the anticipated battle and dining with his captains to ensure they understood his intentions. Nelson had devised a plan of attack that anticipated the allied fleet would form up in a traditional line of battle. Drawing on his own experience from the Nile and Copenhagen, and the examples of Duncan at Camperdown and Rodney at the Saintes, Nelson decided to split his fleet into squadrons rather than forming it into a similar line parallel to the enemy. These squadrons would then cut the enemy's line in a number of places, allowing a pell-mell battle to develop in which the British ships could overwhelm and destroy parts of their opponents' formation, before the unengaged enemy ships could come to their aid.
