Passage 8.39.3
Λακεδαιμόνιοι δὲ ἡνίκα Ἀρκάσιν ἐπεχείρησαν καὶ ἐσέβαλον ἐς τὴν Φιγαλίαν στρατιᾷ, μάχῃ τε νικῶσι τοὺς ἐπιχωρίους καὶ ἐπολιόρκουν προσκαθεζόμενοι· κινδυνεύοντος δὲ ἁλῶναι τοῦ τείχους ἐκδιδράσκουσιν οἱ Φιγαλεῖς, ἢ καὶ οἱ Λακεδαιμόνιοι σφᾶς ἀφιᾶσιν ἐξελθεῖν ὑποσπόνδους. ἐγένετο δὲ ἡ τῆς Φιγαλίας ἅλωσις καὶ Φιγαλέων ἡ ἐξ αὐτῆς φυγὴ Μιλτιάδου μὲν Ἀθήνῃσιν ἄρχοντος, δευτέρῳ δὲ ἔτει τῆς τριακοστῆς Ὀλυμπιάδος, ἣν Χίονις Λάκων ἐνίκα τὸ τρίτον.
When the Lacedaemonians undertook an expedition against the Arcadians and invaded Phigalia with an army, they defeated the inhabitants in battle and placed the city under siege by encamping around it. As the walls were about to fall, the Phigalians either fled secretly, or else the Lacedaemonians allowed them to depart under agreed terms. This capture of Phigalia and the resulting exile of the Phigalians occurred when Miltiades was archon in Athens, in the second year of the thirtieth Olympiad, at which Chionis of Lacedaemon gained his third victory.
