Foureau and Lamy proceeded from Algiers through the Sahara, and met with the other two missions at Kousséri on 21 April 1900. The following day the united French forces confronted Rabih az-Zubayr, a Sudanese warlord who had created an empire in the Chad Basin. In the following battle, in which Lamy was in command with 700 riflemen, while the French reported a crushing victory, Lamy was killed, as was Rabih. In his honour, the first French governor, Émile Gentil, named the capital of the new French territory of Chad Fort-Lamy, which name it bore until it was renamed N'Djamena in 1973.
