HMS Prevost was a 12-gun schooner of unknown origin that the Royal Navy purchased in 1803.

Prevost was returning from the coast of South America with dispatches when she encountered heavy weather that lasted four days.

To stay afloat she threw four of her guns overboard; her rigging was also badly damaged.

[3] At daylight on 31 August 1806, she was about 50 miles from Martinique when she sighted a brig, a schooner, and in time, a sloop.

The engagement began at 1:30pm and lasted about an hour before Stout was forced to strike.
