French West Africa was not the scene of major fighting. Only one large-scale action took place there: the Battle of Dakar (23–25 September 1940). The region remained under the control of Vichy France after the fall of France (25 June 1940) and until the Allied invasion of North Africa (8–16 November 1942). French Gabon, the only colony of French Equatorial Africa not to join Free France after the armistice, fell to invading Free French Forces from the neighbouring colonies after the Battle of Gabon (8–12 November 1940), further isolating West Africa. Unlike in metropolitan France, the French Colonial Troops in West Africa were not reduced after the 1940 armistice and the region was little interfered with by the Axis powers, providing a valuable addition to the forces of Free France after it had been liberated.
