9.15.1 After these things when Alexander held sway in Thessaly, Pelopidas came to him, under the impression that he was well-disposed to him personally as well as a friend to the Theban commonwealth, but on his arrival was treacherously and insolently thrown into prison and kept there by Alexander. The Thebans at once set out to attack Alexander, and made leaders of the expedition Kleomenes and Hypatos, who were Boeotarchs at that time; Epameinondas was serving in the ranks.

9.15.2 When the force had reached the other side of Thermopylae, Alexander surprised and attacked it on difficult ground. As there appeared to be no means of safety, the rest of the army chose Epameinondas to be leader, and the Boeotarchs of their own accord resigned the command. Alexander lost confidence in winning the war when he saw Epameinondas at the head of his opponents, and of his own accord set free Pelopidas.

9.15.3 In the absence of Epameinondas the Thebans removed the Orkhomenians from their land. Epameinondas regarded their removal as a disaster, and declared that had he been present never would the Thebans have been guilty of such an outrage.

9.15.4 Elected again to be Boeotarch, and again invading the Peloponnesus with an army of Boeotians, he overcame the Lacedaemonians in a battle at Lechaeum, and with them Achaeans of Pellene and Athenians led from Athens by Chabrias. The Thebans had a rule that they should set free for a ransom all their prisoners except such as were Boeotian fugitives; these they punished with death. So when he captured the Sikyonian town of Phoebia, in which were gathered most of the Boeotian fugitives, he assigned to each of those whom he captured in it a new nationality, any that occurred to him, and set them free.

9.15.5 On reaching Mantineia with his army, he was killed in the hour of victory by an Athenian.^* In the painting in Athens of the battle of the cavalry the man who is killing Epameinondas is Grylos, the son of the Xenophon who took part in the expedition of Cyrus against king Artaxerxes and led the Greeks back to the sea.

9.15.6 On the statue of Epameinondas is an inscription in elegiac verse relating among other things that he founded Messene, and that through him the Greeks won freedom. The elegiac verses are these:
