THE BATTLE OF PLATAEA

Mardonius was the son of Gobryas, one of the seven conspirators who had put Darius on the throne. He was also married to one of the daughters of Darius. He was an ambitious General, hungry for glory, and he was the primary influence on Xerxes, pressuring him to resume the war with Greece. Mardonius had been put in charge of Darius's first invasion of Greece in 492 B.C., but his fleet was destroyed off the coast of Mount Athos, and he had to return before ever reaching the Greek mainland. Two years later, Darius outfitted another fleet to invade Greece, but instead of Mardonius, the second campaign, which ended after the defeat at Marathon, was lead by Artaphernes and Datis. After the death of Darius, Xerxes himself was undecided regarding the advisability of another campaign in Greece, but Mardonius convinced him to resume the war. It is thought that Mardonius hoped to be Governor, or Satrap, of the Persian Province of Greece.

Mardonius was present at both the battles of Thermopylae and Salamis, and it was on his advise that Xerxes returned to Persia, leaving him in Greece with an army of 300,000 men. Instead of seeking to give battle to the Greek armies, which were now concentrated in the Peloponnese, Mardonius tried to operate as governor of the conquered portion of Greece. He set up his headquarters at Thebes, and consolidated relations with all Greek towns who had surrendered to Persia. He offered Athens favorable terms if they would return to their city and recognize him as their sovereign, an offer which Athens of course, heartily refused. Mardonius, in fact, made no move toward attempting to conquer the Peloponnese, and it finally dawned on the Spartans, that if they were going to drive the invaders from Greek territory, they would have to leave their highly fortified peninsula, and meet him in Boeotia, where the Persian's made camp. Neither side was anxious for battle, and for many weeks the armies camped near each other without engaging. Finally, on a field near Plataea the issue was settled. The Persian army was annihilated, Mardonius was killed, and the Greek city states were free once more.
