When Eurybiades and his party were meditating a retreat from Salamis, the Persian ships put to sea at night and hemmed them in, surrounding both the strait and the islands. No one knew that escape was impossible, but Aristeides sailed from AEgina, passed safely through the enemy’s fleet by a miracle, and while it was still night proceeded straight to the tent of Themistokles. Here he called him out, and when they were alone together, he said: “We two, Themistokles, if we are wise, must cease our vain and silly rivalry with one another, and begin a more generous contest to preserve our country, you acting as general and chief, while I help and advise you. Already I perceive that you alone take a right view of the crisis, end desire to fight a battle in the narrow waters as quickly as possible. Now, while your allies have been opposing you, the enemy have been playing your game, for the sea, both in our front and rear, is full of their ships, so that the Greeks even against their will must play the man and fight; for no way of escape is left for them.” To this Themistokles answered, “I would not willingly, Aristeides, be overcome by you in generosity on this occasion; and I shall endeavour, in emulation of this good beginning which you have made, to surpass it by the glory of my exploits.” At the same time he explained the trick[20] which he had played on the barbarian, and begged Aristeides to argue with Eurybiades, and point out how impossible it was for the Greeks to be saved without fighting; for he thought that the opinion of Aristeides would have more weight than his own. Consequently, when in the assembly of the generals Kleokritus the Corinthian attacked Themistokles, and said that even Aristeides did not approve of his plans, because he was present and said nothing, Aristeides answered that he would not have been silent if Themistokles had not spoken to the purpose, but that as it was he held his peace, not for any love he bore him, but because his counsel was the best.
IX. While the Greek admirals were engaged in these discussions, Aristeides, perceiving that Psyttaleia, a small island in the straits near Salamis, was full of the enemy, placed some of the boldest Athenians on board of small boats, attacked the Persians, and slew them to a man, except a few of the chiefs, who wore taken alive. Among these were the three children of Sandauke the sister of the Persian king, whom he at once sent to Themistokles, and it is said that in accordance with some oracle they were sacrificed to Dionysus Omestes,[21] at the instance of the prophet Euphrantides. Aristeides now lined the shores of the islet with soldiers, ready to receive any vessel which might be cast upon it, in order that neither any of his friends might be lost, nor any of the enemy take refuge upon it. Indeed, the severest encounter between the two fleets and the main shock of the battle seems to have taken place at that spot; wherefore the trophy that marks the victory stands on the isle of Psyttaleia.
