History of the Peloponnesian War

But Pedaritus in the meantime, with the whole power both of his own auxiliary forces and of the Chians, made an assault upon the fortification which the Athenians had made about their navy, part whereof he won, and had gotten some galleys that were drawn a-land. But the Athenians, issuing out upon them, first put to flight the Chians, and then overcame also the rest of the army about Pedaritus, and slew Pedaritus himself, and took many of the Chians prisoners and much armour.

After this the Chians were besieged both by sea and land more narrowly, and great famine was in the city. Pisander, and the other Athenian ambassadors that went with him, when they came to Tissaphernes, began to confer about the agreement.

But Alcibiades (for he was not sure of Tissaphernes, because he stood in fear too much of the Peloponnesians, and had a purpose besides, as Alcibiades himself had taught him, to weaken both sides [yet more]), betook himself to this shift: that Tissaphernes should break off the treaty by making to the Athenians exorbitant demands.
