In February 1809 the French Atlantic Fleet, based at Brest was ordered to sail to the Caribbean to disrupt a British attack on Martinique.
A detachment from the British Channel Fleet, commanded by Admiral Lord Gambier, had followed the French to the harbour and there enacted a close blockade.
[6] Gambier then ordered the reinforcements to withdraw, leaving Cochrane again unsupported against the rest of the main French fleet which was gradually dragging itself off the shoals and into the relative safety of the Charente River.
Cochrane renewed his attack on 13 April but was unable to cause any significant damage to the French ships as they threw stores and guns overboard to facilitate their escape.
[7] On the morning of 14 April Gambier directly ordered Cochrane to retire, turning command of the operation over to Captain George Wolfe.
