General Henri Giraud had switched from Vichy to the Allies and Roosevelt found him a preferable alternative to de Gaulle.[12] Giraud arrived in Algiers on November 10, and agreed to subordinate himself to Darlan as the French African army commander. Even though he was now in the Allied camp, Darlan maintained the repressive Vichy system in North Africa, including concentration camps in southern Algeria and racist laws. Detainees were also forced to work on the Transsaharien railroad.
