Hearing that a great Hibist army under al-Hiba's brother, Merebbi Rebbo, was assembling to the south of them at Ben Guerir, Mangin, without consulting Lyautey, ordered an offensive. Mangin fell on the Hibist army at Ben Guerir on August 29, but with the terrain unfavorable to them, the Hibists broke off the engagement and retreated back towards Marrakesh. The French column returned to Skhour.
