Passage 3.9.12
καὶ ὁ κληθεὶς Κορινθιακὸς πόλεμος ἐς πλέον ἀεὶ προῆλθεν ἀπὸ τῆς Λακεδαιμονίων ἀρξάμενος ἐς Βοιωτίαν ἐξόδου. κατὰ ταύτην μὲν δὴ τὴν ἀνάγκην ὀπίσω τὸ στράτευμα ἐκ τῆς Ἀσίας ἀπῆγεν Ἀγησίλαος· ἐπεὶ δὲ ἐξ Ἀβύδου περαιωθεὶς ναυσὶν ἐς Σηστὸν καὶ διεξελθὼν τὴν Θρᾴκην ἀφίκετο ἐς Θεσσαλίαν, ἐνταῦθα οἱ Θεσσαλοὶ χάριτι τῇ ἐς Θηβαίους τοῦ πρόσω τὸν Ἀγησίλαον ἐπειρῶντο εἴργειν· ἦν δέ τι εὐνοίας ἐκ παλαιοῦ καὶ ἐς τὴν πόλιν αὐτοῖς τὴν Ἀθηναίων.
The so-called Corinthian War continually expanded, having begun with the Lacedaemonians making an incursion into Boeotia. On account of this urgent situation, Agesilaus led back his forces from Asia. Crossing by ships from Abydos to Sestos and marching through Thrace, he arrived in Thessaly. Here, through their goodwill toward the Thebans, the Thessalians attempted to hinder Agesilaus from advancing farther; they were also bound by an ancient friendship toward the city of the Athenians.
