Cyrus returned to Asia Minor with the full determination of attacking his brother at the earliest opportunity. He immediately began the collection of a mercenary force, composed wholly of Greeks, on whose arms he was disposed to place far more reliance than on those of Orientals. As Tissaphernes had returned to the coast with him, and was closely watching all his proceedings, it was necessary to exercise great caution, lest his intentions should become known before he was ready to put them into execution. He therefore had recourse to three different devices. Having found a cause of quarrel with Tissaphernes in the ambiguous terms of their respective commissions, he pressed it on to an actual war, which enabled him to hire troops openly, as against this enemy; and in this way he collected from 5000 to 6000 Greeks--chiefly Peloponnesians. He further gave secret commissions to Greek officers, whose acquaintance he had made when he was previously in these parts, to collect men for him, whom they were to employ in their own quarrels until he needed their services. From 3000 to 4000 troops were gathered for him by these persons. Finally, when he found himself nearly ready to commence his march, he discovered a new foe in the Pisidians of the Western Taurus, and proceeded to levy a force against them, which amounted to some thousands more. In all, he had in readiness 11,000 heavy-armed and about 2000 light-armed Greeks before his purpose became so clear that Tissaphernes could no longer mistake it, and therefore started off to carry his somewhat tardy intelligence to the capital. The aims of Cyrus were different from those of ordinary rebel satraps; and we must go back to the times of Darius Hystaspis in order to find a parallel to them. Instead of seeking to free a province from the Persian yoke, or to carve out for himself an independent sovereignty in some remote corner of the Empire, his intention was to dethrone his brother, and place on his own brows the diadem of his great namesake. It was necessary for him therefore to assume the offensive. Only by a bold advance, and by taking his enemy to some extent unprepared, and so at a disadvantage, could he hope to succeed in his audacious project. It is not easy to see that he could have had any considerable party among the Persians, or any ground for expecting to be supported by any of the subject nations. His following must have been purely personal; and though it may be true that he was of a character to win more admiration and affection than his brother, yet Artaxerxes himself was far from being unpopular with his subjects, whom he pleased by a familiarity and a good-nature to which they were little accustomed. Cyrus knew that his principal dependence must be on himself, on his Greeks, and on the carelessness and dilatoriness of his adversary, who was destitute of military talent and was even thought to be devoid of personal bravery.
