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.
