Charles Louis du Chilleau de La Roche (Fontenay, 26 May 1738 — Paris, 21 August 1825)[1] was a French Navy officer.
On 6 April 1778, with the rank of lieutenant, Du Chilleau de La Roche had command of the 32-gun frigate Diligente.
[6] In February 1780, Du Chilleau de La Roche was given command of a squadron comprising the 64-gun Protée and Ajax and the frigate Charmante, as well as the fluyt Éléphant, escorting a convoy bound for India, with troops and ammunition.
[8] In the action of 24 February 1780, the convoy encountered a British force under George Rodney, and Protée sacrificed herself to cover the retreat of her fellows.
While the convoy sailed on to the Indian Ocean with Ajax, Charmante returned to Lorient to bring the news of the battle, arriving there on 3 March.
