Passage 7.3.4
Κολοφωνίοις δὲ ὅπως μὲν τὴν πόλιν συνέπεσεν ἐρημωθῆναι, προεδήλωσέ μοι τοῦ λόγου τὰ ἐς Λυσίμαχον· ἐμαχέσαντο δὲ Λυσιμάχῳ καὶ Μακεδόσι Κολοφώνιοι τῶν ἀνοικισθέντων ἐς Ἔφεσον μόνοι, τοῖς δὲ ἀποθανοῦσιν ἐν τῇ μάχῃ Κολοφωνίων τε αὐτῶν καὶ Σμυρναίων ἐστὶν ὁ τάφος ἰόντι ἐς Κλάρον ἐν ἀριστερᾷ τῆς ὁδοῦ.
As for how the city of Colophon happened to become desolate, I have already indicated this earlier in my account concerning Lysimachus. Of those who had been resettled into Ephesus, the people of Colophon alone fought against Lysimachus and the Macedonians. The tomb of those who fell in this battle—both Colophonians themselves and Smyrnaeans—is located on the left-hand side of the road as one goes toward Claros.
