Passage 10.23.11
Ἀθηναίων δὲ ἄνδρες ἐπισκεψόμενοι μὲν ἀφίκοντο ἐν Δελφοῖς· τότε δὲ ἐπανήκοντες τά τε ἄλλα ἤγγελλον ὁποῖα συμβεβήκει τοῖς βαρβάροις καὶ τὰ ἐκ τοῦ θεοῦ κατειληφότα. οἱ δὲ αὐτοί τε ἐξεστρατεύοντο καὶ ὡς τὴν Βοιωτίαν διώδευον οἱ Βοιωτοί σφισιν ἀνεμίχθησαν· οὕτω δὴ ἀμφότεροι τοῖς βαρβάροις ἐπακολουθοῦντες ἐλόχων τε καὶ ἔκτεινον τοὺς ἀεὶ ἐσχάτους.
Some men of the Athenians had gone to Delphi to make inquiry, and upon their return they reported both what had happened to the barbarians, and the oracle they had received from the god. The Athenians themselves then marched out, and as they were passing through Boeotia, the Boeotians joined forces with them. Thus united, both groups followed after the barbarians, ambushed them, and repeatedly slew those who were falling behind.
