Passage 7.15.6
ἀπιοῦσι δὲ ὀπίσω σφίσιν ἐς τὴν Πελοπόννησον Μέτελλος καὶ Ῥωμαῖοι περὶ Χαιρώνειαν ἐπιφαίνονται· ἔνθα δὴ ἐπελάμβανε τοὺς Ἀρκάδας ἐκ θεῶν δίκη τῶν Ἑλληνικῶν, οἳ ἐν Χαιρωνείᾳ Φιλίππου καὶ Μακεδόνων ἐναντία ἀγωνιζομένους ἐγκαταλιπόντες Ἕλληνας τότε ἐν χωρίῳ τῷ αὐτῷ ἐκτείνοντο ὑπὸ Ῥωμαίων.
On their retreat back toward the Peloponnesus, Metellus and the Romans attacked them near Chaeroneia. Here indeed divine justice overtook the Arcadians for their betrayal of the Greek cause; having deserted the Greeks at Chaeroneia when they fought against Philip and the Macedonians, they were now laid low by the Romans in the very same place.
