"Aeolus" spent the rest of 1805 and 1806 on the Irish station, before departing for Halifax in August 1807. She was then in the Caribbean, taking part in the capture of Martinique in February 1809. She formed part of a small squadron with HMS "Cleopatra" and the brig HMS "Recruit", which was sent into Fort-de-France Bay on 5 February. Panicked by the advance the French militia defending the bay set fire to the ships anchored there, including the frigate "Amphitrite", and abandoned the forts in the southern part of the island. In 1847 the Admiralty awarded the Naval General Service Medal with clasp "Martinique" to all surviving claimants from the campaign.
