Battle of Piraeus
The Battle of Piraeus was fought in 403 BC between Athenian exiles who had defeated the government of the Thirty Tyrants and occupied Piraeus and a Spartan force sent to combat them. In the battle, the Spartans narrowly defeated the exiles, with both sides suffering appreciable casualties. After the battle, Pausanias arranged a settlement between the two parties which allowed the reestablishment of democratic government in Athens.
