Passage 7.13.7
Μεναλκίδας δὲ ᾕρητο μὲν ὑπὸ Λακεδαιμονίων ἐναντία Διαίῳ στρατηγεῖν· ἐχόντων δὲ αὐτῶν ἔς τε τὴν πᾶσαν πολέμου παρασκευὴν καὶ οὐχ ἥκιστα τοῖς χρήμασιν ἀσθενῶς, πρὸς δὲ καὶ τῆς γῆς σφισιν ἀσπόρου μεμενηκυίας, † διας ὅμως τὰς σπονδὰς ὑπερβῆναι καὶ πόλισμα Ἴασον ἑλὼν ἐξ ἐπιδρομῆς ἐπόρθησεν, ἐν ὅροις μὲν χώρας τῆς Λακωνικῆς, Ἀχαιῶν δὲ ἐν τῷ τότε ὑπήκοον.
Menalkidas had been selected by the Lacedaemonians to lead against Diaeus, but they themselves were weak in their preparation for war generally, and particularly deficient in money, while moreover their land had remained unproductive. Yet, in spite of the truce, he crossed its bounds and captured by assault the stronghold named Iasos, devastating it—a place located on the borders of the Laconian region but at that time subject to the Achaeans.
