Passage 10.23.13
καὶ τὸ ἀπὸ τούτου δὲ οἱ βάρβαροι μέχρι μὲν τοῦ Σπερχειοῦ χαλεπῶς ἐκομίσθησαν, τῶν Αἰτωλῶν βιαίως σφίσιν ἐγκειμένων· ὡς δὲ ἀφίκοντο ἐπὶ τὸν Σπερχειόν, οἱ ἐντεῦθεν ὑποκαθήμενοι Θεσσαλοὶ καὶ οἱ Μαλιεῖς ἐνεφορήθησαν οὕτω σφῶν ὡς μηδένα οἴκαδε ἀποσωθῆναι.
From this point onward the barbarians made their retreat to the Spercheius only with great difficulty, harassed violently by the Aetolians. And when they arrived at the Spercheius, the Thessalians and Malians, who lay hidden in ambush there, fell upon them and destroyed them so utterly that none returned home alive.
