Book IV

[In the preceding portion of the narrative a full account is given of the incidents of the march up to the battle, and of the occurrences after the battle during the truce which was established between the king and the Hellenes, who marched up with Cyrus, and thirdly, of the fighting to which the Hellenes were exposed, after the king and Tissaphernes had broken the treaty, while a Persian army hung on their rear. Having finally reached a point at which the Tigris was absolutely impassable owing to its depth and breadth, while there was no passage along the bank itself, and the Carduchian hills hung sheer over the river, the generals took the resolution above mentioned of forcing a passage through the mountains. The information derived from the prisoners taken along the way led them to believe that once across the Carduchian mountains they would have the choice either of crossing the Tigris—if they liked to do so—at its sources in Armenia, or of going round them, if so they preferred. Report further said that the sources of the Euphrates also were not far from those of the Tigris, and this is actually the case. The advance into the country of the Carduchians was conducted with a view partly to secrecy, and partly to speed, so as to effect their entry before the enemy could occupy the passes.]
