The action of 18 June 1793 was one of the most celebrated encounters between British and French frigates during the French Revolutionary Wars. The action occurred off Start Point in Devon, when the British frigate HMS Nymphe encountered and chased the French frigate Cléopâtre. During the previous month, Cléopâtre and another frigate, Sémillante, had been successfully raiding British merchant shipping in the English Channel and Eastern Atlantic from their base at Cherbourg. In response, the British frigates Nymphe and HMS Venus had been ordered to intercept and defeat the French frigates and on 27 May Venus and Sémillante fought an inconclusive engagement off Cape Finisterre.
