When the Gauls found out there were two Roman armies in the area they split up and pursued both. The main body met Labienus who pinned them down with one legion while surrounding them with the rest. He then annihilated their reinforcements with his cavalry.Julius Caesar, ''Commentarii de Bello Gallico'', VII, 62. After linking up with the five cohorts he had used as a diversion, Labienus marched his army back to Agendicum where he met up with Caesar returning from his defeat at Gergovia. The combined Roman army would soon after march from Agendicum to face Vercingetorix's victorious army coming from the south. After defeating the Gauls in the Battle of the Vingeanne near the river of Vingeanne, Caesar pursued them to Alesia where he won a decisive victory over Vercingetorix.
