Battle of Plataea
Mardonius prepared to meet them at the Plataea, despite the opposition from another Persian commander, Artabazus, who, like Artabanus, did not think that the Persian army could automatically defeat the Greeks. Mardonius was killed in the ensuing battle by the Spartans (see Battle of Plataea). It is claimed by Herodotus and Plutarch a Plataean called Aeimnestus killed Mardonius. This led to his army breaking up.
