121. They then, I say, though hard put to it, yet were performing that which was appointed to them; and from Acanthos Xerxes, after having commanded the generals to wait for the fleet at Therma, let the ships take their course apart from himself, (now this Therma is that which is situated on the Thermaic gulf, from which also this gulf has its name); and thus he did because he was informed that this was the shortest way: for from Doriscos as far as Acanthos the army had been making its march thus:--Xerxes had divided the whole land-army into three divisions, and one of them he had set to go along the sea accompanying the fleet, of which division Mardonios and Masistes were commanders; another third of the army had been appointed to go by the inland way, and of this the generals in command were Tritantaichmes and Gergis; and meanwhile the third of the subdivisions, with which Xerxes himself went, marched in the middle between them, and acknowledged as its commanders Smerdomenes and Megabyzos. 122. The fleet, when it was let go by Xerxes and had sailed right through the channel made in Athos (which went across to the gulf on which are situated the cities of Assa, Piloros, Singos and Sarte), having taken up a contingent from these cities also, sailed thence with a free course to the Thermaïc gulf, and turning round Ampelos the headland of Torone, it left on one side the following Hellenic cities, from which it took up contingents of ships and men, namely Torone, Galepsos, Sermyle, Mekyberna, Olynthos: this region is called Sithonia. 123. And the fleet of Xerxes, cutting across from the headland of Ampelos to that of Canastron, which runs out furthest to sea of all Pallene, took up there contingents of ships and men from Potidaia, Aphytis, Neapolis, Aige, Therambo, Skione, Mende and Sane, for these are the cities which occupy the region which now is called Pallene, but was formerly called Phlegra. Then sailing along the coast of this country also the fleet continued its course towards the place which has been mentioned before, taking up contingents also from the cities which come next after Pallene and border upon the Thermaïc gulf; and the names of them are these,--Lipaxos, Combreia, Lisai, Gigonos, Campsa, Smila, Aineia; and the region in which these cities are is called even to the present day Crossaia. Then sailing from Aineia, with which name I brought to an end the list of the cities, at once the fleet came into the Thermaïc gulf and to the region of Mygdonia, and so it arrived at the aforesaid Therma and at the cities of Sindos and Chalestra upon the river Axios. This river is the boundary between the land of Mygdonia and Bottiaia, of which district the narrow region which lies on the sea coast is occupied by the cities of Ichnai and Pella.
