In the battle, an Athenian fleet commanded by Alcibiades, Thrasybulus, and Theramenes routed and completely 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.
