If the account of the evacuation of Athens implied by the Themistocles decree is accurate, the Herodotean account of the events of 480 BC must be revised to reflect a Greek strategy, agreed on in June, focused on stopping the Persian advance at Salamis and the Isthmus of Corinth. If this was indeed the Greek plan, then Thermopylae and Artemisium, which Herodotus describes as all-out attempts to defeat the Persian invasion, would in fact have been only holding actions intended to give time for the evacuation of Attica and the preparation of the defenses of the isthmus.
