Hervey distinguished himself in several encounters with the French, and was of great assistance to Admiral Hawke in 1759, although he had returned to England before the Battle of Quiberon Bay in November 1759. He took command of the third-rate HMS "Dragon" in March 1760 and saw action during the Capture of Belle Île in June 1761, the Invasion of Martinique in January 1762 and the Battle of Havana in June 1762 before transferring to the fourth-rate HMS "Centurion" in May 1763.
