Leissègues' squadron had escaped from Brest on 13 December 1805, taking advantage of a lapse in the British blockade. Sailing with another squadron under "Contre-amiral" Jean-Baptiste Willaumez, Leissègues separated from Willaumez after two days and passed north of the Azores, where his ships were damaged and scattered by winter storms. Sailing for Santo Domingo to reconstitute his squadron and make urgent repairs, Leissègues arrived on 20 January 1806. Duckworth had been tasked with watching the remnants of the French and Spanish fleets in Cádiz following the Battle of Trafalgar in October 1805, but in November had gone hunting to the south in search of a French raiding squadron and on his route back to his station had encountered a frigate that reported the escape of Leissègues and Willaumez. Sailing in pursuit, Duckworth encountered Willaumez on 25 December but refused battle and instead sailed for the West Indies to replenish his supplies before making the journey back to European waters. News reached him of the French arrival while anchored at Basseterre on 1 February and he immediately sailed to investigate, joined by part of the West Indies squadron under Rear-Admiral Alexander Cochrane.
