On the 10th of November 1759 he led Hawke's fleet as captain of the "Magnanime" (64) in the magnificent victory of Quiberon.
His last political achievement was in July 1795, when he was present with Hoche at the destruction of the army of the emigres at Quiberon, and ordered the executions which followed.
He restored their cattle to the peasants who submitted, "let the priests have a few crowns," and on the 20th of July 1795 annihilated an émigré expedition which had been equipped in England and had seized Fort Penthievre and Quiberon.
He was in North America in 1755, on the coast of France in 1756, was detached on a cruise to reduce the French settlements on the west coast of Africa in 1758, and his ship the "Torbay" (74) was the first to get into action in the battle of Quiberon in 1759.
In the same year the naval victories of Lagos and Quiberon Bay established the supremacy of the British at sea.
