Battle of Aegospotami

The naval Battle of Aegospotami 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. Prelude Lysander's campaigns In 405 BC, following the severe Spartan defeat at the Battle of Arginusae, Lysander, the commander who had been responsible for the first Spartan naval successes, was reinstated in command. Since the Spartan constitution prohibited any commander from holding the office of navarch more than once, he was appointed as a vice-admiral instead, with the clear understanding that this was a mere legal fiction.
