He was promoted to Captain in 1757. In 1761, he commanded the 74-gun Diadème, making voyages between Saint-Domingue and Brest. The year after, he captained Protée. In 1765, he had command of the 32-gun frigate Licorne, and took part in the Larache expedition.

He was promoted to Chef d'escadre in 1767. That same year, he conducted a mission to Morocco with the 64-gun Union, ferrying diplomats to negotiate peace. From 1772 to 1775, he commanded the fleet at Brest. In 1774, he was involved in the inquiry into the fire that had destroyed Mars at Isle de France (Mauritius) the year before.

He was promoted to Lieutenant-général in on 1 March 1779. Between 1779 and 1784, he was commanding officer for the forces in Lorient.

In October 1782, Breugnon was president of a court-martial investigating Captain Sillans for the loss of the 74-gun Pégase at the Battle of Ushant on 21 April. Sillans was cashiered and expelled from the Navy. The year after, Breugnon presided the inquiry held in Lorient to investigate the events of the Battle of the Saintes.
