According to Lewis, the Muslim soldiers were accompanied by their families. Wives and concubines were among the casualties. Realizing their camp was being plundered, a large contingent of Abdul Rahman's forces broke off battle and returned to rescue their booty. Abdul Rahman was thus left exposed before the Frankish infantry and was killed in battle while attempting to rally his men. One reason for the defeat of the Muslim army was their preoccupation with war booty; another was the squabbles between various ethnic and tribal factions, which led to the surviving generals being unable to agree on a single commander to take Abdul Rahman's place. Political factions, racial and ethnic rivalries, and personality clashes arose following his death. The varied nationalities and ethnicities present in an army drawn from all over the Caliphate, and the surviving generals, bickered among themselves, unable to agree on a commander to lead them the following day. The inability to select anyone to lead certainly contributed to the wholesale retreat of an army that was still dangerous.
