Following independence, the first President of Cameroon, Ahmadou Ahidjo requested continued French military intervention to fight the UPC rebels.
The war is believed to have produced some 61,300 to 76,300 civilian deaths, according to estimates from the British embassy assembled in 1964, with 80% of the dead being from the Bamileke Region.
