Battle of Abydos
The Battle of Abydos was an Athenian naval victory in the Peloponnesian War. In the battle, the Spartan fleet, under Mindarus, attempted to rescue a small allied fleet that had been driven ashore at Dardanus, but was attacked by the Athenian fleet, under Thrasybulus. The fighting was evenly contested for a great length of time, but towards evening, the arrival of Alcibiades with Athenian reinforcements tipped the balance in favor of the Athenians, and the Peloponnesians were forced to flee back to their base at Abydos, suffering heavy losses along the way.
