He participated in the Entrecasteaux expedition, which Louis XVI and the Constituent Assembly directed to search for the earlier La Pérouse expedition, as well as conduct scientific research in the Pacific Ocean.

In the year XI, he commanded La Franchise during the Léogane Affair. In his report, the vicomte de Rochambeau, general-in-chief of the Army of Saint-Domingue, made note of him as an officer distinguished by his intelligence and bravery and demanded he receive the rank of ship-of-the-line captain, which was granted on the 13th of Ventôse.

In the year XII, he was made a French legionnaire in Pluviôse and an officer of the order on 25 Prairial. He received the latter again in February 1809. He fought in 1809 at the battle of Sables-d'Olonne, employing three frigates to force the retreat of six British ships-of-the-line.

He was named on 7 January 1827 as the naval prefect of the 4th arrondissement and on 5 November as the president of the electoral college of Charente.
