Which near-simultaneous battle with Plataea destroyed much of the Persian fleet?

The Battle of Mycale was the near-simultaneous Greek victory with Plataea that destroyed much of the remaining Persian fleet. It took place in 479 BCE on the Ionian coast of Asia Minor.

After Xerxes withdrew from Greece, a Persian army under Mardonius remained and was defeated at Plataea. At the same time, a Greek fleet under the Spartan commander Leotychides sailed to confront Persian naval forces based near Samos. The Persians beached their ships and fortified a camp below Mount Mycale rather than risk an open-water battle.

Greek marines landed and attacked the Persian position. Once the Persian troops were routed, the Greeks captured and burned the beached ships. Ionian contingents serving with Persia also changed sides or undermined the Persian defense, helping turn the battle into a major Greek success.

Herodotus presented Mycale and Plataea as victories won on the same day, although some modern historians question the exact synchronization. That uncertainty does not change Mycale’s identity as the battle that crippled Persian sea power and helped end the invasion.
