History of the Peloponnesian War

After these things the Chians were besieged still more closely than before, both by land and sea, and the famine in the place was great. In the mean time, the Athenian ambassadors with Pisander arrived at the court of Tissaphernes, and conferred with him respecting the convention.

But as Alcibiades could not depend on the views of Tissaphernes, who was more afraid of the Peloponnesians, and wished still (as he had been instructed by him) to wear both parties out, he had recourse to the following plan, in order that Tissaphernes, by demanding the greatest possible concessions from the Athenians, might avoid coming to terms with them. Tissaphernes also, in my opinion, wished the same result, being himself led to do so by fear:

but Alcibiades, when he saw that the satrap was not, under any circumstances, desirous of making an agreement, wished the Athenians to think that he was not incapable of persuading him, but that when Tissaphernes had been persuaded, and was willing to join them, the Athenians did not concede enough to him.

For Alcibiades, speaking in person in behalf of Tissaphernes, who was also present, made such excessive demands, that the refusal of the Athenians, although for a long time they conceded whatever he asked, was still the apparent cause of their failure. For they required the whole of Ionia to be given up, and then again the adjacent islands, with other things; and when the Athenians did not object to these demands, at last, in their third interview, being afraid that he would certainly be convicted of inability to keep his word, he demanded that they should permit the king to build ships, and sail along his own coast, wherever and with how many soever he might please. Upon that the Athenians complied no longer, but considering that the business was impracticable, and that they had been deceived by Alcibiades, they departed in a rage, and went to Samos.
