History of the Peloponnesian War

However, Alcibiades, not being altogether sure of Tissaphernes (who feared the Peloponnesians more than the Athenians, and besides wished to wear out both parties, as Alcibiades himself had recommended), had recourse to the following stratagem to make the treaty between the Athenians and Tissaphernes miscarry by reason of the magnitude of his demands.

In my opinion Tissaphernes desired this result, fear being his motive; while Alcibiades, who now saw that Tissaphernes was determined not to treat on any terms, wished the Athenians to think, not that he was unable to persuade Tissaphernes, but that after the latter had been persuaded and was willing to join them, they had not conceded enough to him.

For the demands of Alcibiades, speaking for Tissaphernes, who was present, were so extravagant that the Athenians, although for a long while they agreed to whatever he asked, yet had to bear the blame of failure: he required the cession of the whole of Ionia, next of the islands adjacent, besides other concessions, and these passed without opposition; at last, in the third interview, Alcibiades, who now feared a complete discovery of his inability, required them to allow the king to build ships and sail along his own coast wherever and with as many as he pleased. Upon this the Athenians would yield no further, and concluding that there was nothing to be done, but that they had been deceived by Alcibiades, went away in a passion and proceeded to Samos.

Tissaphernes immediately after this, in the same winter, proceeded along shore to Caunus, desiring to bring the Peloponnesian fleet back to Miletus, and to supply them with pay, making a fresh convention upon such terms as he could get, in order not to bring matters to an absolute breach between them. He was afraid that if many of their ships were left without pay they would be compelled to engage and be defeated, or that their vessels being left without hands, the Athenians would attain their objects without his assistance. Still more he feared that the Peloponnesians might ravage the continent in search of supplies.
