The fleets resupplied and settled in to await the arrival of a large French fleet from Brest under Vice-Admiral Honoré Joseph Antoine Ganteaume. Unbeknownst to Villeneuve, Ganteaume was still being blockaded in Brest. The combined fleet achieved little while in the West Indies, managing only to capture the British-held Diamond Rock after two weeks of sitting idle at anchor. The small garrison surrendered on 2 June, by which time the frigate "Didon" had arrived with orders. Villeneuve was instructed to attack and capture the British colonies in the West Indies, before sailing his entire force back to Europe, join Ganteaume at Brest and cover the invasion flotilla. Villeneuve gathered his forces and pressed northwards towards Antigua, but on 7 June he came across a lightly defended convoy of British merchants, and captured several of them the following day. From them he discovered that Nelson was in hot pursuit, and had arrived at Barbados. Villeneuve decided to break off operations and return to Europe. The fleet got underway on 11 June.
