The Battle of Cyzicus in 410 BC was a small-scale naval battle during the Peloponnesian War between an Athenian fleet led by Alcibiades and a Peloponnesian fleet led by Sparta. Alcibiades led the Athenian fleet to a decisive victory, but the outcome had little overall effect and the Spartans rebuilt their fleet and placed it under the command of Lysander. Several other sea battles followed, Notium and Mytilene were small Spartan wins, Arginusae a large Athenian win, and finally the Battle of Aegospotami where Lysander surprised the Athenian fleet and annihilated it.
