43. The camp was under the command of Marcus Aemilius, tribune of the soldiers, the son of that Marcus Lepidus who a few years later became pontifex maximus.¹ [2] When he saw the flight of his men, he met them with his entire guard and ordered them first to halt and then to return to the battle, taunting them with fear and disgraceful flight; [3] then [p. 417]he uttered threats that they were rushing blindly to² their own deaths if they did not obey his orders; finally, he gave the signal to his own men to kill the first of the fugitives and with steel and wounds to drive against the enemy the mass of those that followed. [4] This greater fear prevailed over the lesser; driven by terror in front and rear they first halted; then they too returned to the fight, and Aemilius with his own guard —they were two thousand gallant men —boldly [5] withstood the onrushing king, and Attalus, the brother of Eumenes, from the right flank, where the enemy's left had been routed at the first attack, when he saw the flight of the troops on the left and the mellay around the camp, himself came in the nick of time with two hundred cavalry. [6] When Antiochus saw the troops at whose backs he had just been looking returning to the fight, and another body coming from the camp and another from the battle-line, he turned his horse to flight. [7] So on both wings the victorious Romans, over piles of corpses which they had heaped up, especially in the centre, where the strength of the bravest troops³ and the weight of their arms had delayed the flight of the enemy, proceeded to plunder the camp. [8] The cavalry of Eumenes first of all, then the rest of the cavalry, pursued the enemy over the whole plain, killing the hindmost as they overtook them. [9] But a greater peril to the fugitives, the chariots and elephants and camels being mingled with them, was the disordered mob of their own men, since their ranks once broken, as if blind they rushed one over [p. 419]the other or were trampled down by the charging⁴ beasts. [10] In the camp also there was great slaughter, greater, almost, than on the battle-field; for the first body of fugitives had chiefly made for the camp and, gaining confidence from this increase in numbers, the garrison fought with greater stubbornness from the rampart. [11] The Romans, finding themselves held up at the gates and by the wall, which they had expected to carry at the first onset, when they finally broke through, in their passion caused greater destruction.
