The army reaches Issi, the last city in Cilicia, at which the fleet then arrives. Cyrus proceeds into Syria, where two of the Greek captains, Xenias and Pasion, desert the expedition; the good feeling of Cyrus, in forbearing to pursue them, renders the other Greeks more willing to accompany him. He arrives at Thapsacus on the Euphrates, where he discloses the real object of his expedition to the Greek troops, who express discontent, but are induced by fresh promises, and the example of Menon, to cross the river.The army proceeds through Arabia, having the Euphrates on the right. They suffer from want of provisions, and many of the beasts of burden perish; but supplies are procured from the opposite bank of the Euphrates. A dispute occurs between Clearchus and Menon, which is quelled by Cyrus.CHAPTER V.
