Losing his father at a young age, he soon entered the French Navy, starting his service during the Seven Years' War, notably at the battle of Quiberon Bay.
Following that battle he and the chevalier de Ternay saved part of the French fleet which had taken refuge in the Vilaine estuary.
He was promoted to capitaine de vaisseau then squadron commander at the start of the American Revolutionary War.
He was visited at Brest by the future Tsar Nicholas I and his family and at Cherbourg on an inspection by Louis XVI of France.
He ended his career at the rank of lieutenant general.
