Hodgson led a British raid on Belle Île, off the coast of France. After the initial British attack was repulsed a second attempt forced a beachhead. A second landing was made and, after a six-week siege, the island's main citadel at Le Palais was stormed, consolidating British control of the island in June 1761. He was much congratulated by both the King and William Pitt, Secretary of State for the Southern Department, as this "important and critical operation" enabled the British Government to use Belle Île as a bargaining piece during the negotiations leading up to the Treaty of Paris in 1763. Promoted to lieutenant general on 23 March 1765, he became Governor of Fort George and Fort Augustus in September 1765.
