Lysander was appointed Spartan navarch (admiral) for the Aegean Sea in 407 BC.
It was during this period that he gained the friendship and support of Cyrus the Younger, a son of Darius II of Persia and Parysatis.

Lysander then undertook the major project of creating a strong Spartan fleet based at Ephesus which could take on the Athenians and their allies.

Alcibiades was appointed commander-in-chief with autocratic powers of the Athenian forces and left for Samos to rejoin his fleet and try and engage Lysander in battle.
The Spartan navarch Lysander refused to be lured out of Ephesus to do battle with Alcibiades.
However, while Alcibiades was away seeking supplies, the Athenian squadron was placed under the command of Antiochus, his helmsman.
During this time Lysander managed to engage the Athenian fleet and they were routed by the Spartan fleet (with the help of the Persians under Cyrus) at the Battle of Notium in 406 BC.
This defeat by Lysander gave the enemies of Alcibiades the excuse they needed to strip him of his command.
He never returned again to Athens.
He sailed north to the land he owned in the Thracian Chersonese.
