In 1757, Wolfe participated in the British amphibious assault on Rochefort, a seaport on the French Atlantic coast. A major naval descent, it was designed to capture the town, and relieve pressure on Britain's German allies who were under French attack in Northern Europe. Wolfe was selected to take part in the expedition partly because of his friendship with its commander, Sir John Mordaunt. In addition to his regimental duties, Wolfe also served as Quartermaster General for the whole expedition. The force was assembled on the Isle of Wight and after weeks of delay finally sailed on 7 September.
