Passage 7.11.8
προσγενομένου δὲ τοῦ Καλλικράτους πρὸς τὴν Μεναλκίδου γνώμην ἐκεκύρωτο κατὰ Ἀθηναίων ἀμύνειν Ὠρωπίοις. καί τις ἐξαγγέλλει ταῦτα ἐς τοὺς Ἀθηναίους· οἱ δὲ ὡς ἕκαστος τάχους εἶχεν ἐς τὸν Ὠρωπὸν ἐλθόντες καὶ αὖθις κατασύραντες εἴ τι ἐν ταῖς προτέραις παρεῖτό σφισιν ἁρπαγαῖς, ἀπάγουσι τὴν φρουράν. Ἀχαιοὺς δὲ ὑστερήσαντας τῆς βοηθείας Μεναλκίδας μὲν καὶ Καλλικράτης ἐσβάλλειν ἐς τὴν Ἀττικὴν ἔπειθον· ἀνθισταμένων δὲ ἄλλων τε αὐτοῖς καὶ οὐχ ἥκιστα τῶν ἐκ Λακεδαίμονος, ἀνεχώρησεν ὀπίσω τὸ στράτευμα.
When Callicrates had added his support to the counsel of Menalcidas, it was decreed that the Achaeans should come to the aid of the Oropians against the Athenians. But someone brought news of this to the Athenians, and they, each setting forth as quickly as he could, hastened to Oropus, seized immediately whatever had been overlooked in their former raid, and carried off the garrison. After the Achaeans failed to arrive in time to provide assistance, Menalcidas and Callicrates urged them to invade Attica. However, encountering opposition from others and especially from the men of Lacedaemon, the army withdrew and turned back.
