44. About fifty thousand infantry are said to have been slain on that day and three thousand cavalry; fourteen hundred were captured and fifteen elephants with their drivers. [2] Of the Romans, many were wounded; there were killed not more than three hundred infantry and twenty-four cavalry, and from the army of Eumenes twenty-five.

[3] And on that day, indeed, the victors, having plundered the camp of the enemy, returned to their own laden with booty; on the next day they despoiled the bodies of the slain and gathered up the prisoners. [4] Ambassadors from Thyatira and Magnesia near Sipylus came to surrender their cities. Antiochus, fleeing with a few companions and collecting more along the way, with a moderate-sized body of soldiers reached Sardis about midnight. [5] Thence, when he heard that his son Seleucus and some of his friends had gone to Apamea, he too, about the fourth watch, with his wife and daughter sought Apamea. [6] The guardianship of the city¹ was handed over to Xeno, and Timo was placed in charge of Lydia; [7] but no regard was paid to them and, with the consent of the citizens and the soldiers who [p. 421]were in the citadel, ambassadors were sent to the² consul.
