The Invasion of Dominica (7 September 1778) was a successful French invasion of the island of Dominica in the British West Indies, during the American Revolutionary War. The action took place before British authorities in the Caribbean were aware that France had entered the war as an ally of the United States of America. The French governor in the West Indies, François Claude Amour, marquis de Bouillé, was notified on 17 August that France was at war, and organized the invasion, infiltrating spies to rally sympathetic French-speaking Dominican support.
