A doubtful story says that Themistocles, foreseeing that if the battle was long delayed the Spartan party would carry their point and withdraw to the isthmus, ran the risk of sending a message to King Xerxes, urging him to attack at once, hinting at a defection of the Athenian fleet, and telling him that if he acted without delay the Greeks were at his mercy, and that they were so terrified that they were thinking chiefly of how they might escape. Herodotus tells of a council of war of the Persian leaders at which the fighting Queen Artemisia stood alone in advising delay. She told the King that in overrunning northern Greece he had done enough for one campaign. Let him settle down for winter quarters in Attica and he would see the Greek armament, already divided by jealousies and quarrels, break up and disperse. He could then prepare quietly for the conquest of the Peloponnesus in the spring. But Xerxes was more flattered by the opinion of the satraps who told him that he had only to stretch out his hands to destroy the Greek fleet and make himself undisputed master of the sea. And, just as Themistocles was despairing of being able to keep the fleet at Salamis, news came that the Persians had decided to attack. The news was brought by Aristides, the son of Lysimachus, who had been unjustly exiled from Athens some years before, but now in the moment of his country's danger ran the blockade of the Persians in a ship of Ægina, and came to throw in his lot with his fellow-citizens. For the Greeks to set out for the isthmus under these circumstances would be to risk having to meet superior numbers in the open sea. All now agreed that the fate of Greece was to be decided in the waters of Salamis. Xerxes looked forward to the coming struggle with assured hope of victory, and prepared to enjoy the spectacle of the disaster that was about to fall upon his enemies.
