The action of 21 July 1781 (French: Combat naval en vue de Louisbourg, or Combat naval à la hauteur de Louisbourg) was a naval skirmish off the harbour of Spanish River, Cape Breton, Nova Scotia (present-day Sydney, Nova Scotia), during the War of American Independence. Two light frigates of the French Navy, captained by Jean-François de Galaup, comte de Lapérouse and Louis-René Levassor de Latouche Tréville, engaged a convoy of 18 British ships and their Royal Navy escorts. The French captured one of the British escorts while the remainder of the British convoy escaped.
