Thermopylae (lit. hot gates) was a pass the Greeks tried to defend in battle against the Persian forces led by Xerxes, in 480 B.C. The Greeks (Spartans and allies) knew they were outnumbered and hadn't a prayer, so it was no surprise that the Persians won the Battle of Thermopylae.
The Battle of Plataea was the final land battle during the second Persian invasion of Greece. It took place in 479 BC near the city of Plataea in Boeotia, and was fought between an alliance of the Greek city-states, including Sparta, Athens, Corinth and Megara, and the Persian Empire of Xerxes I.erxes then retreated with much of his army, leaving his general Mardonius to finish off the Greeks the following year. In the summer of 479 BC the Greeks assembled a huge (by ancient standards) army and marched out of the Peloponnesus. The Persians retreated to Boeotia and built a fortified camp near Plataea.
