Thus overpowered by the Peloponnesian allies, Themistocles is said to have bethought himself of a stratagem, not inconsonant with his scheming and wily character. Retiring privately from the debate, yet unconcluded, and summoning the most confidential messenger in his service [82], he despatched him secretly to the enemy's fleet with this message--"The Athenian leader, really attached to the king, and willing to see the Greeks subjugated to his power, sends me privately to you. Consternation has seized the Grecian navy; they are preparing to fly; lose not the opportunity of a splendid victory. Divided among themselves, the Greeks are unable to resist you; and you will see, as you advance upon them, those who favour and those who would oppose you in hostility with each other." The Persian admiral was sufficiently experienced in the treachery and defection of many of the Greeks to confide in the message thus delivered to him; but he scarcely required such intelligence to confirm a resolution already formed. At midnight the barbarians passed over a large detachment to the small isle of Psyttaleia, between Salamis and the continent, and occupying the whole narrow sea as far as the Attic port of Munychia, under cover of the darkness disposed their ships, so as to surround the Greeks and cut off the possibility of retreat. XV. Unconscious of the motions of the enemy, disputes still prevailed among the chiefs at Salamis, when Themistocles was summoned at night from the council, to which he had returned after despatching his messenger to the barbarian. The person who thus summoned him was Aristides. It was the third year of his exile--which sentence was evidently yet unrepealed--or not in that manner, at night and as a thief, would the eminent and high-born Aristides have joined his countrymen. He came from Aegina in an open boat, under cover of the night passed through the midst of the Persian ships, and arrived at Salamis to inform the Greeks that they were already surrounded. "At any time," said Aristides, "it would become us to forget our private dissensions, and at this time especially; contending only who should most serve his country. In vain now would the Peloponnesians advise retreat; we are encompassed, and retreat is impossible." Themistocles welcomed the new-comer with joy, and persuaded him to enter the council and acquaint the leaders with what he knew. His intelligence, received with doubt, was presently confirmed by a trireme of Tenians, which deserted to them; and they now seriously contemplated the inevitable resort of battle. XVI. At dawn all was prepared. Assembled on the strand, Themistocles harangued the troops; and when he had concluded, orders were given to embark. It was in the autumn of 480 B. C., two thousand three hundred and sixteen years ago, that the battle of Salamis was fought.
