Jean-Marie Kersauson de Goasmelquin (also spelled Kersauzon and Goasmelquen)[1] was a French Navy officer.
He fought in the War of American Independence, and took part in the French operations in the Indian Ocean under Suffren.
[3] 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.
However, he failed to seize the opportunity to engage the British from point-blank range, instead taking a position behind Illustre.
[4][Note 1] Kersauson was promoted to Captain on 31 July 1784.
