The Battle of Dakar, also known as Operation Menace, was an unsuccessful attempt in September 1940 by the Allies to capture the strategic port of Dakar in French West Africa (modern-day Senegal). It was hoped that the success of the operation could overthrow the pro-German Vichy French administration in the colony, and be replaced by a pro-Allied Free French one under General Charles de Gaulle.
