Aréthuse served between France and the Caribbean. On 9 October 1799 she was sailing towards Impregnable and her convoy when the 74-gun Excellent, which was to windward of Impregnable, spotted her. Excellent chased Aréthuse, catching her during the night. Captain Robert Stopford of Excellent described Aréthuse as having eighteen 9-pounder guns and a crew of 153 men, all under the command of a lieutenant de vaisseau. She was sailing from Lorient to Cayenne with dispatches that she succeeded in destroying before she struck. Excellent shared the capture with Impregnable.
