What role did Themistocles play during the Greco-Persian Wars?

Themistocles was an Athenian statesman and naval commander who helped prepare Athens for a Persian attack by building up its fleet. He led the Greek naval forces at the Battle of Salamis, where they defeated the Persian fleet. Themistocles did not record the wars—that was Herodotus—and the defense of the pass at Thermopylae was led by King Leonidas of Sparta.
