As had been the case in 1914, substantial numbers of the Army of Africa were moved to mainland France on the outbreak of World War II. In May 1940 14 regiments of zouaves, 42 regiments of Algerian, Tunisian and Moroccan tirailleurs, 12 regiments and demi-brigades of the Foreign Legion and 13 battalions of African Light Infantry were serving on all fronts.[12]
