French Cameroons
A French counterattack with reinforced troops was launched in late 1928 and on December 11, Karnou was killed by a French military patrol. The rebellion, however, continued to spread unevenly from the Sangha basin to include the neighbouring groups from Cameroon and the lower Ubangi region, namely in the Mbéré and Vina valleys of French Cameroons, around the towns of Baïbokoum and Moïssala in southern Chad, around the towns of Yaloke, Bambio, Ndele and Boda in the Mambéré-Kadéï and Lobaye regions of Ubangi-Shari, and around the town of Berandjoko in the French Congo.
