After Pierrevert, Bellone 's new captain, was killed in the action of 12 August 1782, Suffren returned Beaulieu to Bellone. To replace Beaulieu on Brillant, he appointed Lieutenant de Kersauson captained Brillant.

At the Battle of Trincomalee, from 25 August to 3 September 1782, Brillant was the only ship to return from the vanguard to support the French main battle body, as ordered.
