Paragraph 173 173. Thus spoke the Thessalians; and the Hellenes upon this resolved to send to Thessaly by sea an army of men on foot to guard the pass: and when the army was assembled it set sail through Euripos, and having come to Alos in the Achaian land, it disembarked there and marched into Thessaly leaving the ships behind at Alos, and arrived at Tempe, the pass which leads from lower Macedonia into Thessaly by the river Peneios, going between the mountains of Olympos and Ossa. There the Hellenes encamped, being assembled to the number of about ten thousand hoplites, and to them was added the cavalry of the Thessalians; and the commander of the Lacedemonians was Euainetos the son of Carenos, who had been chosen from the polemarchs, 165 not being of the royal house, and of the Athenians Themistocles the son of Neocles. They remained however but few days here, for envoys came from Alexander the son of Amyntas the Macedonian, who advised them to depart thence and not to remain in the pass and be trodden under foot by the invading host, signifying to them at the same time both the great numbers of the army and the ships which they had. When these gave them this counsel, they followed the advice, for they thought that the counsel was good, and the Macedonian was evidently well-disposed towards them. Also, as I think, it was fear that persuaded them to it, when they were informed that there was another pass besides this to the Thessalian land by upper Macedonia through the Perraibians and by the city of Gonnos, the way by which the army of Xerxes did in fact make its entrance. So the Hellenes went down to their ships again and made their way back to the Isthmus.
Paragraph 174 174. Such was the expedition to Thessaly, which took place when the king was about to cross over from Asia to Europe and was already at Abydos. So the Thessalians, being stripped of allies, upon this took the side of the Medes with a good will and no longer half-heartedly, so that in the course of events they proved very serviceable to the king.
