Hi Franck,
Actually sometimes after WWII, the German dead in Southern France were gathered in big war cemeteries. As a general rule, all dead of Southwest France were gathered in Berneuil and all dead of Southeast France in Dagneux, near Lyon.
Berneuil war cemetery now has 8 342 graves coming from 15 departements.
