 Following the Fashoda incident and the Franco-Egyptian treaty of 1899 which ceded Bahr El Ghazal to the Anglo-Egyptian Sudan, the French forces left the post in 1900.In 1900, an Anglo-Egyptian "reoccupation" force of Egyptian and Sudanese soldiers entered Bahr El Ghazal.Most of them had reportedly been recruited from the defeated Mahdist army and ""were chiefly ex-slave natives of the Province"", which caused some unease amongst the population.
