Passage 7.13.1
αὖθις οὖν ἐκ τῶν ἀντιλογιῶν Λακεδαιμονίοις ὥρμηντο Ἀχαιοὶ πολεμεῖν, καὶ στρατὸς ἐπὶ τὴν Σπάρτην ἠθροίζετο ὑπὸ Δαμοκρίτου στρατηγεῖν τηνικαῦτα Ἀχαιῶν ᾑρημένου. περὶ δὲ τὸν αὐτὸν χρόνον τοῦτον ἀφίκετο ἐς Μακεδονίαν στρατιά τε Ῥωμαίων καὶ ἡγεμὼν ἐπʼ αὐτῇ Μέτελλος, Ἀνδρίσκῳ τῷ Περσέως τοῦ Φιλίππου πολεμήσοντες ἀφεστηκότι ἀπὸ Ῥωμαίων. καὶ ὁ μὲν ἐν Μακεδονίᾳ πόλεμος ἔμελλεν ὡς ῥᾷστα κατὰ τὸ ἐπιτηδειότατον Ῥωμαίοις κριθήσεσθαι·
Again then, because of their grievances against the Lacedaemonians, the Achaeans resolved to wage war, and an army was being gathered against Sparta, with Damocritus having then been chosen as general of the Achaeans. At about the same time, a Roman army arrived in Macedonia under the command of Metellus, prepared to fight Andriscus, son of Perseus, son of Philip, who had revolted against the Romans. And the war in Macedonia promised to end most easily and favorably for the Romans.
