Battle between Athenian exiles and the Spartan-backed oligarchic government of the Thirty Tyrants
The Battle of Munychia was fought between Athenians exiled by the oligarchic government of the Thirty Tyrants and the forces of that government, supported by a Spartan garrison. In the battle, a substantially superior force composed of the Spartan garrison of Athens and the army of the oligarchic government attacked a hill in Piraeus (the Munychia) which had been seized by 1,000 exiles under Thrasybulus, but was defeated. After this defeat, the Thirty Tyrants were forced to flee to Eleusis.
