§7.174.1αὕτη ἐγένετο ἡ ἐς Θεσσαλίην στρατηίη, βασιλέος τε μέλλοντος διαβαίνειν ἐς τὴν Εὐρώπην ἐκ τῆς Ἀσίης καὶ ἐόντος ἤδη ἐν Ἀβύδῳ.
This was the expedition to Thessaly, while the king was about to cross from Asia into Europe and was already in Abydos.
Θεσσαλοὶ δὲ ἐρημωθέντες συμμάχων οὕτω δὴ ἐμήδισαν προθύμως οὐδʼ ἔτι ἐνδοιαστῶς, ὥστε ἐν τοῖσι πρήγμασι ἐφαίνοντο βασιλέι ἄνδρες ἐόντες χρησιμώτατοι.
But the Thessalians, having been left destitute of allies, did then so eagerly and no longer with hesitation side with the Medes, that in actual events they showed themselves to be most useful men to the king.
