 The destruction of this army, and the remnants of the Persian navy allegedly on the same day at the Battle of Mycale, decisively ended the invasion.After Plataea and Mycale the Greek allies would take the offensive against the Persians, marking a new phase of the Greco-Persian Wars.Although Plataea was in every sense a resounding victory, it does not seem to have been attributed the same significance (even at the time) as, for example, the Athenian victory at the Battle of Marathon or the Spartan defeat at Thermopylae.
