By place

Greece

• The Athenian general Thrasybulus recaptures Abdera and Thasos.
• The Spartan admiral Lysander refuses to be lured out of Ephesus to do battle with Alcibiades. However, while Alcibiades is away seeking supplies, the Athenian squadron is placed under the command of Antiochus, his helmsman, who is routed by the Spartan fleet in the Battle of Notium.
• The defeat gives the enemies of Alcibiades an excuse to strip him of his command. He never returns again to Athens. He sails north to land he owns in the Thracian Chersonese. Except for a brief appearance at Aegospotami, Alcibiades' involvement in the Peloponnesian War is over.
