When he reached the Greek fleet, the commanders were in council, agitating, in angry and incriminating debates, the perpetually recurring question whether they should retire to the isthmus, or remain where they were. Aristides called Themistocles out of the council. Themistocles was very much surprised at seeing his ancient enemy thus unexpectedly appear. Aristides introduced the conversation by saying that he thought that at such a crisis they ought to lay aside every private animosity, and only emulate each other in the efforts and sacrifices which they could respectively make to defend their country; that he had, accordingly, come from AEgina to join the fleet, with a view of rendering any aid that it might be in his power to afford; that it was now wholly useless to debate the question of retiring to the isthmus, for such a movement was no longer possible. "The fleet is surrounded," said he. "The Persian galleys are stationed on every side. It was with the utmost difficulty that I could make my way through the lines. Even if the whole assembly, and Eurybiades himself, were resolved on withdrawing to the isthmus, the thing could not now be done. Return, therefore, and tell them this, and say that to defend themselves where they are is the only alternative that now remains." In reply to this communication, Themistocles said that nothing could give him greater pleasure than to learn what Aristides had stated. "The movement which the Persians have made," he said, "was in consequence of a communication which I myself sent to them. I sent it, in order that some of our Greeks, who seem so very reluctant to fight, might be compelled to do so. But you must come yourself into the assembly," he added, "and make your statement directly to the commanders. They will not believe it if they hear it from me. Come in, and state what you have seen." Aristides accordingly entered the assembly, and informed the officers who were convened that to retire from their present position was no longer possible, since the sea to the west was fully guarded by lines of Persian ships, which had been stationed there to intercept them. He had just come in himself, he said, from AEgina, and had found great difficulty in passing through the lines, though he had only a single small boat, and was favored by the darkness of the night. He was convinced that the Greek fleet was entirely surrounded. Having said this, Aristides withdrew. Although he could come, as a witness, to give his testimony in respect to facts, he was not entitled to take any part in the deliberations.
