In 1759, Charles took command of the 32-gun Blonde-class frigate Brune, which sailed from her base in Lorient towards the naval base in Brest and witnessed the Battle of Quiberon Bay. In 1762 the ship was once again at sea grouped with the Defence and Diadème which led a long campaign in 1762 with the Marquis de Montreil bound for Saint Pierre and Newfoundland.
