Passage 9.5.13
καὶ οἱ μὲν μονομαχοῦντες ἀποθνήσκουσιν, ἐς δὲ Λαοδάμαντα τὸν Ἐτεοκλέους καθηκούσης τῆς βασιλείας Κρέων ὁ Μενοικέως ἐδυνάστευεν ἐπιτροπεύων τὸν παῖδα. ἤδη δὲ Λαοδάμαντος ηὐξημένου καὶ ἔχοντος τὴν ἀρχήν, δεύτερον τότε ἄγουσι τὴν στρατιὰν ἐπὶ τὰς Θήβας· ἀντεστρατοπεδευμένων δὲ καὶ τῶν Θηβαίων περὶ Γλίσαντα, ὡς ἐς χεῖρας συνῆλθον, Αἰγιαλέα μὲν τὸν Ἀδράστου Λαοδάμας ἀποκτίννυσι, κρατησάντων δὲ τῇ μάχῃ τῶν Ἀργείων Λαοδάμας σὺν τοῖς ἐθέλουσιν ἕπεσθαι Θηβαίων ὑπὸ τὴν ἐπιοῦσαν νύκτα ἀπεχώρησεν ἐς Ἰλλυριούς.
And those fighting in single combat died, and when the kingship fell to Laodamas, the son of Eteocles, Creon, son of Menoeceus, exercised authority, acting as guardian for the boy. When Laodamas grew older and took up the rule, then for the second time the Argives led their army against Thebes. The Thebans encamped opposite them around Glisas, and when the two armies engaged in battle, Laodamas killed Aegialeus, the son of Adrastus. But since the Argives won the battle, Laodamas, accompanied by those of the Thebans who voluntarily followed him, withdrew the following night to the land of the Illyrians.
