History of the Peloponnesian War

Now Alcibiades advised the king and Tissaphernes to this whilst he was with them, partly because he thought the same to be indeed the best course, but partly also to make way for his own return into his country, knowing that if he destroyed it not, the time would one day come that he might persuade the Athenians to recall him. And the best way to persuade them to it, he thought, was this: to make it appear unto them that he was powerful with Tissaphernes.

Which also came to pass. For after the Athenian soldiers at Samos saw what power he had with him, the captains of galleys and principal men there, partly upon Alcibiades' own motion, who had sent to the greatest amongst them that they should remember him to the best sort and say that he desired to come home so the government might be in the hands of a few, not of evil persons nor yet of the multitude that cast him out, and that he would bring Tissaphernes to be their friend, [and to war on their side], but chiefly of their own accords had their minds inclined to the deposing of the popular government.

This business was set on foot first in the camp and from thence proceeded afterwards into the city. And certain persons went over to Alcibiades out of Samos and had conference with him. And when he had undertaken to bring to their friendship first Tissaphernes and then the king, in case the government were taken from the people, for then, he said, the king might the better rely upon them, they that were of most power in the city, who also were the most toiled out, entered into great hope both to have the ordering of the state at home themselves and victory also over the enemy.

And when they came back to Samos, they drew all such as were for their purpose into an oath of conspiracy with themselves, and to the multitude gave it out openly that if Alcibiades might be recalled and the people put from the government, the king would turn their friend and furnish them with money.

Though the multitude were grieved with this proceeding for the present, yet for the great hope they had of the king's pay they stirred not. But they that were setting up the oligarchy, when they had communicated thus much to the multitude, fell to consideration anew and with more of their complices of the things spoken by Alcibiades.
