Herodotus recounts that, on the afternoon of the Battle of Plataea, a rumour of their victory at that battle reached the Allies' navy, at that time off the coast of Mount Mycale in Ionia. Their morale boosted, the Allied marines fought and won a decisive victory at the Battle of Mycale that same day, destroying the remnants of the Persian fleet, crippling Xerxes's sea power, and marking the ascendancy of the Greek fleet. Whilst many modern historians doubt that Mycale took place on the same day as Plataea, the battle may well only have occurred once the Allies received news of the events unfolding in Greece.
