The more suitable partners, he said, with whom to share the sovereignty were the Athenians; for they were less desirous of possessions on land and both their principles and practice in carrying on war were most consistent with his interests; for whereas the Athenians would co-operate with him in making subject to themselves the department of the sea and to him such of the Hellenes as lived in the King's country, the Lacedaemonians, on the contrary, had come to liberate these. It was not reasonable, he added, to suppose that the Lacedaemonians would now be liberating the Hellenes from men who, like themselves, were Hellenes, and would not liberate them from the Persians who were Barbarians, unless these sooner or later got them out of the way.

And Tissaphernes was more inclined to this course, so far as it was possible to conjecture from what he was doing. For he consequently gave his support and confidence to Alcibiades, as though he thought his advice in the matter good, and not only furnished wretched maintenance to the Peloponnesians, but also would not allow them to fight at sea; instead, he kept telling them that the Phoenician ships would come and that they would then contend with superabundant strength; and thus he injured their cause and diminished the vigour of their fleet, which had been very strong; and in general it was too evident to escape notice that he was not zealously co-operating in the war.

And the means by which he thought he could best persuade them was this—to make it appear that Tissaphernes was on intimate terms with him;
