The Battle of Aegospotami (Greek: Μάχη στους Αιγός Ποταμούς) was a naval confrontation that took place in 405 BC and was the last major battle of the Peloponnesian War. In the battle, a Spartan fleet under Lysander destroyed the Athenian navy. This effectively ended the war, since Athens could not import grain or communicate with its empire without control of the sea.
