Thanks to this, by the beginning of the war the Greeks possessed 200 ships

At the battle at Salamis Themistocles greatly outsmarted Xerxes' fleet commanders

To stop army he made a wooden wall of ships at the isthmus

Xerxes found Athens empty and burned it to the ground

Themistocles sent a servant to tell Xerxes she was a traitor, and relay that:

There was a Greek escape at dawn and that Xerxes should send his main fleet across the Bay to catch them

Following this advice, the Persians entered the Bay at a bad angle and got jammed together, making it impossible to fight back well

The outcome was a Greek victory, with the Persian fleet almost completely destroyed
