In 1925, the French writer André Gide published "Voyage au Congo", in which he described the alarming consequences of conscription for the Congo-Ocean railroad. He exposed the continuing atrocities committed against Central Africans in Western Ubangi-Shari by such employers as the Forestry Company of Sangha-Ubangi. In 1928, a major insurrection, the Kongo-Wara rebellion or 'war of the hoe handle', broke out in Western Ubangi-Shari and continued for several years. The extent of this insurrection, which was perhaps the largest anti-colonial rebellion in Africa during the interwar years, was carefully hidden from the French public because it provided evidence of strong opposition to French colonial rule and forced labor.
