Kingdom of Commagene
Paetus invaded the Kingdom of Commagene as head of the Legio VI Ferrata. The client Kings Aristobulus of Chalcis and Sohaemus of Emesa also supplied troops to Paetus, all of which arrived the night before the battle. As Epiphanes and Callinicus prepared themselves that night for war, Antiochus IV was preparing to flee to Cilicia.
