So the townsmen, oppressed as they were, nevertheless did as they were commanded. Upon leaving Acanthus, Xerxes sent his ships on their course away from him, giving orders to his generals that the fleet should await him at Therma, the town on the Thermaic gulf which gives the gulf its name, for this, he learned, was his shortest way. The order of the army's march, from Doriscus to Acanthus, had been such as I will show. Dividing his entire land army into three parts, Xerxes appointed one of them to march beside his fleet along the coast. Mardonius and Masistes were the generals of this segment, while another third of the army marched, as appointed, further inland under Tritantaechmes and Gergis. The third part, with which Xerxes himself went, marched between the two, and its generals were Smerdomenes and Megabyzus.
