At the same time, the French colonial administration began to force the local population to pay taxes and to provide the state with free labor. The companies and the French administration at times collaborated in forcing the Central Africans to work for them. Some French officials reported abuses committed by private company militias, and their own colonial colleagues and troops, but efforts to hold these people accountable almost invariably failed. When any news of atrocities committed against Central Africans reached France and caused an outcry, investigations were undertaken and some feeble attempts at reform were made, but the situation on the ground in Ubangi-Shari remained virtually unchanged.
