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 War of Independence. 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.
Early on 7 September 1778, French forces landed on the southeastern coast of the island. They rapidly took over some of the island's defences, and eventually gained control of the high ground overlooking the island capital, Roseau. Lieutenant Governor William Stuart then surrendered the remaining forces. Dominica remained in French hands until the end of the war, when it was returned to British control.
