[Sidenote: Domitius Ahenobarbus conquered and slain by Pompeius in Africa.] Pompeius found Domitius strongly posted behind a ravine. Taking advantage of a tempest, he crossed it and routed the enemy. His men hailed him Imperator: but he said he would not take the title till they had taken the camp. The camp was then stormed and Domitius slain. Pompeius also captured the towns held by the partisans of Domitius, and defeated and took prisoner the Marian usurper who had expelled Hiempsal, King of Numidia. Hiempsal was restored and his rival put to death. On returning to Utica Pompeius found a message from Sulla, telling him to disband his troops except one legion and wait till his successor came. [Sidenote: Vanity of Pompeius.] The men mutinied, for they liked Pompeius, and Sulla was told that Pompeius was in rebellion. He remarked that 'in his old age it was his fate to fight with boys'--a saying to which Pompeius's speech, 'that more men worshipped the rising than the setting sun,' may have been intended as a rejoinder. But soon he was relieved by hearing that the politic Pompeius had appeased the mutiny. Sulla had the art of yielding with a good grace when it was necessary, and, seeing how popular Pompeius was, he went out to meet him on his return and greeted him by the name 'Magnus.' The vain young man asked for a triumph. His forty days' campaign had indeed been brilliant; but he was not even a praetor, the lowest official to whom a triumph was granted, nor a senator, but only an eques. Sulla at first was astonished at the request, but contemptuously replied, 'Let him triumph; let him have his triumph.'
