content with passing along unobserved, but lingering by the way to harass the enemy, and endeavouring to detach from Carbo every part of Italy that he visited. VII. Now there rose up against him three hostile generals at once, Carinna,[200] and Clœlius and Brutus, not all in front, nor yet all from the same quarter, but they surrounded him with three armies, with the view of completely destroying him. Pompeius was not alarmed, but getting all his force together he attacked one of the armies, that of Brutus, placing in the front his cavalry, among whom he himself was. From the side of the enemy the Celtæ rode out to meet him, when Pompeius with spear in hand struck the first and strongest of them and brought him down; on which the rest fled and put the infantry also into confusion, so that there was a general rout. Hereupon the generals quarrelled among themselves and retired, as each best could, and the cities took the part of Pompeius, seeing that the enemy had dispersed in alarm. Next came Scipio[201] the consul against him, but before the lines had come close enough to discharge their javelins, the soldiers of Scipio saluted those of Pompeius and changed sides, and Scipio made his escape. Finally, near the river Arsis,[202] Carbo himself attacked Pompeius with several troops of horse, but Pompeius bravely stood the attack, and putting them to flight pursued and drove all of them upon difficult ground where no cavalry could act; and the men, seeing that there was no hope of saving themselves, surrendered with their arms and horses.
