Pelopidas (15.1-15.2)

After this, the Athenians with the greatest eagerness renewed their alliance with the Thebans, and began hostile operations against Sparta by sea, sailing about and inviting and receiving the allegiance of those Greeks who were inclined to revolt. The Thebans, too, by always engaging singly in Boeotia with the Lacedaemonians, and by fighting battles which, though not important in themselves, nevertheless afforded them much practice and training,

had their spirits roused and their bodies thoroughly inured to hardships, and gained experience and courage from their constant struggles. For this reason Antalcidas the Spartan, we are told, when Agesilaüs came back from Boeotia with a wound, said to him: Indeed, this is a fine tuition-fee which thou art getting from the Thebans, for teaching them how to war and fight when they did not wish to do it.
