At the Battle of Arausio, Caepio refused to co-operate with his superior officer, consul Gnaeus Mallius Maximus, who was a New Man, not a member of the Roman Elite. Caepio refused to even camp with Maximus and his troops, when it appeared that Maximus was going to reach a treaty and take the glory for the resolution, Caepio ordered his men to engage the Germans, and the battle that ensued saw the complete destruction of the Roman army.
