Editing Epaminondas (section)

====Second invasion of the Peloponnesus (369 BC)====
In 369&nbsp;BC the Argives, Eleans and the Arcadians, eager to continue their war against Sparta, once more called on Thebes to support them. Epaminondas, at the height of his prestige, again commanded an allied invasion force. Arriving at the isthmus of Corinth, the Thebans found it heavily guarded by both Spartans and Athenians (along with the Corinthians, [[Megara]]ns and [[Pellene|Pellenians]]). Epaminondas decided to attack the weakest spot, guarded by the Spartans; in a dawn attack he forced his way through their position, and joined his Peloponnesian allies. The Thebans thus won an easy victory and crossed the isthmus. Diodorus stresses that this was "a feat no whit inferior to his former mighty deeds".{{sfn|Tritle|1997|p=88}}

However, the rest of the expedition achieved little: Sicyon and Pellene became allied to Thebes, and the countryside of [[Troezen]] and [[Epidaurus]] was ravaged, but the cities could not be taken. After an abortive attack on Corinth and the arrival of a relief force sent by [[Dionysius I of Syracuse|Dionysius of Syracuse]] to aid Sparta, the Thebans decided to march home.{{sfn|Cawkwell|1972|p=267}}{{sfn|Stylianou|1998|p=452}}{{sfn|Tritle|1997|pp=88{{ndash}}89}}
