This article focuses on the post war period, a largely forgotten issue of the study of the history of Great War campaign in Cameroon. The paper analyses how in the First World War aftermath, Kamerunian soldiers who have been enrolled in the German colonial army (Schutztruppe) adapted to the new socio-economic and political contours created by the departure of their military masters. Drawing from the theoretical framework of "New Military History", and using mainly primary records like archival materials, interviews and then secondary literature, the article will re-interrogate the social trajectories of these soldiers, and the challenges they faced in the post Great War period. How these soldiers rehabilitated themselves and adapted to the new socio-political and military environments imposed by the French and British victors following the Great War expeditions, will be examined. This helps link the past with the present, and brings to light the sacrifices of Cameroonian military men over time.
