Battle of Plataea, (July 479 BCE). Following the Greek naval success at the Battle of Salamis in 480 BCE, Persian King Xerxes left Greece with much of his army. However, his general, Mardonius, remained in northern Greece to continue the fight. The war’s deciding encounter at Plataea the next summer proved to be a crushing Greek victory.
Although Xerxes had returned to Asia and the Persian fleet had retreated to the eastern Aegean (and would be defeated there in 479 BCE), Mardonius still had a vast army, substantially larger than the Greek alliance’s force. After initial maneuvers, Mardonius established a base at Plataea in the territory of Persia’s ally, Thebes. The Greek army, under the Spartan Pausanius, assembled on hills near the Persian camp to confront them.
