The Battle of Mycale was one of the two major battles (the other being the Battle of Plataea) that ended the second Persian invasion of Greece during the Greco-Persian Wars. It took place on 27 or 28 August, 479 BC on the slopes of Mount Mycale, which is located on the coast of Ionia opposite the island of Samos. The battle was fought between an alliance of Greek city-states, including Sparta, Athens and Corinth; and the Persian Empire of Xerxes I.
The previous year, the Persian invasion force, led by Xerxes himself, had scored victories at the battles of Thermopylae and Artemisium, and conquered Thessaly, Boeotia and Attica; however, at the ensuing Battle of Salamis, the Greek navy had won an unlikely victory, and therefore prevented the conquest of the Peloponnese. Xerxes then retreated, leaving his general Mardonius with a substantial army to finish off the Greeks the following year.
