Battle of Kouno: Gentil's column routs Rabih az-Zubayr's forces in French Equatorial Africa

Background. Captain Émile Gentil led the Gentil Mission, one of three French armed columns organized in 1899–1900: the Gentil Mission proceeding north from French Congo, the Voulet–Chanoine Mission east from Niger, and the Foureau-Lamy Mission south from Algeria. Gentil had secured a treaty of alliance with Sultan Abd ar Rahman Gwaranga in 1897, giving France a protectorate over the Kingdom of Baguirmi, then threatened by Rabih az-Zubayr. On 16 August 1899 Gentil learned that Rabih had annihilated the Bretonnet-Braun Mission at Togbao on 17 July. His primary goal was to unite with the Voulet–Chanoine Mission, but he felt he first had to free himself of Rabih, and left Fort-Archambault on 23 October, leaving twenty men under maréchal de logis Bauguies.

The Engagement. The Gentil Mission burned the town of Kouno and confronted Rabih az-Zubayr's forces at the Battle of Kouno on 28 October 1899. The French were pushed back, suffering losses, in an engagement described as inconclusive. This did not prevent the mission from linking up with the other French columns at Kousséri on 21 April 1900, in what today is northern Cameroon. A legacy row's claim that the battle occurred near Fort-Archambault is not supported by the supplied passages, which place the battle at Kouno.

Colonial Context. The battle occurred within the context of French colonial expansion in Chad. Rabih az-Zubayr was a powerful warlord who had established an empire in Central and West Africa. His forces were well-equipped and organized. The French viewed Rabih as illegitimate, using opposition to the slave trade as a justification for military action against him.
