Passage 3.5.3
τὸ δὲ ἄλλο ἀπέγνω δικαστήριον. μετὰ δὲ οὐ πολὺν χρόνον Λακεδαιμονίων συλλεγόντων ἐπὶ Θήβας στρατιάν---αἰτία δὲ ἥτις ἐγένετο προσέσται τῷ ἐς Ἀγησίλαον λόγῳ---, τότε δὲ Λύσανδρος μὲν ἐς τὴν Φωκίδα ἀφικόμενος καὶ ἀναλαβὼν πανδημεὶ τοὺς Φωκέας οὐδένα ἔτι ἐπισχὼν χρόνον ἔς τε Βοιωτίαν ἐληλύθει καὶ προσβολὰς ἐποιεῖτο ἐς τὸ Ἁλιαρτίων τεῖχος οὐκ ἐθελόντων ἀπὸ Θηβαίων ἀφίστασθαι. ἐσεληλύθεσαν δὲ ἤδη καὶ Θηβαίων καὶ Ἀθηναίων τινὲς κρύφα ἐς τὴν πόλιν, ὧν ἐπεξελθόντων καὶ πρὸ τοῦ τείχους ταξαμένων ἄλλοι τε ἐνταῦθα Λακεδαιμονίων καὶ Λύσανδρος ἔπεσε.
The remaining charges the court rejected. A short time afterwards, the Lacedaemonians began gathering an army against Thebes—the reason for which expedition I will explain in my account of Agesilaus. At that time, Lysander arrived in Phocis, and having mustered the entire Phocian force without any further delay, entered Boeotia and began assaulting the walls of Haliartus, since the people there were unwilling to revolt from the Thebans. Meanwhile, some Thebans and Athenians had already secretly entered the city; these troops now sallied forth and drew up their ranks before the walls. In the battle that followed, several Lacedaemonians fell, including Lysander himself.
