From the end of 1942, the Army of Africa was headed by French general Henri Giraud and fought in the Tunisia Campaign before its merger with General Charles de Gaulle's Free French Forces. North African units subsequently played a major role in the liberation of Corsica (September - October 1943) and the Italian Campaign (1943–44) in the French Expeditionary Corps. During the French and German campaigns of 1944-45 the Army of Africa was expanded to 260,000 men (including 50% Indigenes and 50% white French settlers in North Africa, Pied-Noir),[14] including the 1st Motorized Infantry Division (Zouaves and Foreign Legion), the 1st Armoured Division(Chasseurs d' Afrique and Foreign Legion), the 2nd and 4th Moroccan Infantry Divisions (Moroccan Tirailleurs), and the 3rd Algerian Infantry Division (Algerian and Tunisian Tirailleurs).
