In 1793 he was promoted to Captain, but was relieved during the French Revolution due to his noble background.
He was reinstated in 1794 and given the rank of rear admiral.
He commanded a squadron of 6 vessels and three frigates based in Toulon during Richery's expedition.
These ships were among the small squadrons used by the French to raid British commerce.
In one of its remarkable engagements, his squadron captured convoy of trading vessels (around thirty vessels), which the squadron took to Cadiz where it was blockaded by the British.
In 1795, he carried out a raid on Saint-Dominigue and captured another enemy convoy.
Richery also participated in series of conflicts in 1790s with the British in Canada, landing at Bay Bulls on September 1796.
His squadron then carried out raids on the British coasts of Newfoundland.
His squadron also bombarded and destroyed English fisheries in the area.
