, Plataea

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.
