De Gaulle's support grew out of a base in colonial Africa. In the fall of 1940, the colonial empire largely supported the Vichy regime. Félix Éboué, governor of Chad, switched his support to General de Gaulle in September. Encouraged, de Gaulle traveled to Brazzaville in October, where he announced the formation of an Empire Defense Council in his "Brazzaville Manifesto", and invited all colonies still supporting Vichy to join him and the Free French forces in the fight against Germany, which most of them did by 1943.
