Cause

French colonies at Isle Bonaparte and Isle de France served as bases for privateers and frigates conducting commerce raiding against British shipping. The Cannonière encountered a strongly escorted British convoy off the Cape Colony, prompting it to attempt flight from the superior British warship HMS Tremendous.

Event

The 40-gun French frigate Cannonière was brought to action by the 74-gun HMS Tremendous. Captain Bourayne employed superior seamanship, executing maneuvers that neutralized the British ship's broadside batteries and threatened it with raking fire, turning a potentially disastrous engagement into a defensible contest.

Consequence

The Cannonière successfully evaded and escaped HMS Tremendous despite being significantly outgunned. The engagement demonstrated that skilled maneuvering could allow a lighter frigate to survive and disengage from a ship of the line, preserving French raiding capacity in the Indian Ocean.
