Following Athens' defeat in the
Peloponnesian War, a narrow
oligarchic government was imposed on the city by
Lysander and the victorious Spartans. This government, which came to be known as the Thirty Tyrants as a result of its brutal actions, exiled or drove away a number of citizens. Many of these gathered at Thebes, where they received support and assistance from the anti-Spartan government of
Ismenias. Late in 404 BC, 70 of these exiles, commanded by
Thrasybulus, crossed the border into
Attica and occupied the strong point of Phyle on
Mount Parnes. The Thirty, seeking to dislodge this threat, marched out to attack Phyle, but, after an initial assault was repulsed, a snowstorm drove the force back to Athens. Meanwhile, more exiles began to arrive at Phyle, swelling the size of the force there. The Thirty dispatched the Spartan garrison of Athens, along with an Athenian cavalry force, to keep watch on Phyle and prevent the exiles from raiding the countryside. ==Battle==
