Battle of Cyzicus
The Battle of Cyzicus (Greek: Kyzikos) took place in May or June 410 BC during the Peloponnesian War. During the battle, an Athenian fleet commanded by Alcibiades, Thrasybulus, and Theramenes routed and destroyed a Spartan fleet commanded by Mindarus. The victory allowed Athens to recover control over a number of cities in the Hellespont over the next year. In the wake of their defeat, the Spartans made a peace offer, which the Athenians rejected.
