Off the island of Salamis the Greek fleet sinks most of the Persian ships in the battle. Herodotus says the Greeks fought in line while the Persian ships lost their order.
Since the Hellenes fought in an orderly fashion by line, but the barbarians were no longer in position and did nothing with forethought, it was likely to turn out as it did.
A Greek army led by the Spartan Pausanias routs the Persian land army under Mardonius, ending Xerxes' invasion of Greece.
On that day the Spartans, as the oracle had foretold, gained from Mardonius their full measure of vengeance for the slaying of Leonidas, and the most glorious of victories of all which we know was won by Pausanias, the son of Cleombrotus, who was the son of Anaxandrides.
