Passage 10.23.3
ἀπέθανον δὲ καὶ αὐτῶν παρὰ τὸ ἔργον τῶν Φωκέων ἄλλοι τε ἀριθμὸν πολλοὶ καὶ Ἀλεξίμαχος, ὃς ἐν τῇ μάχῃ ταύτῃ μάλιστα Ἑλλήνων ἡλικίας τε τῷ ἀκμάζοντι καὶ ἰσχύι σώματος καὶ τῷ ἐρρωμένῳ τοῦ θυμοῦ κατεχρήσατο ἐς τῶν βαρβάρων τὸν φόνον· Φωκεῖς δὲ εἰκόνα τοῦ Ἀλεξιμάχου ποιησάμενοι ἀπέστειλαν τῷ Ἀπόλλωνι ἐς Δελφούς.
Among the Phocians themselves, many others died during this action, as well as Aleximachus, who, more than any of the Greeks in this battle, by virtue of his youthful prime, bodily strength, and great courage, wrought destruction upon the barbarians. The Phocians made a statue of Aleximachus and dedicated it to Apollo at Delphi.
