Retreat being resolved upon, it only remained to determine what route should be followed, and on what portion of the Roman territory the march should be directed. The soldiers clamored for a return by the way whereby they had come; but many valid objections to this course presented themselves to their commanders. The country along the line of the Euphrates had been exhausted of its stores by the troops in their advance; the forage had been consumed, the towns and villages desolated. There would be neither food nor shelter for the men along this route; the season was also unsuitable for it, since the Euphrates was in full flood, and the moist atmosphere would be sure to breed swarms of flies and mosquitoes. Julian saw that by far the best line of retreat was along the Tigris, which had higher banks than the Euphrates, which was no longer in flood, and which ran through a tract that was highly productive and that had for many years not been visited by an enemy. The army, therefore, was ordered to commence its retreat through the country lying on the left bank of the Tigris, and to spread itself over the fertile region, in the hope of obtaining ample supplies. The march was understood to be directed on Cordyene (Kurdistan), a province now in the possession of Rome, a rich tract, and not more than about 250 miles distant from Ctesiphon. Before, however, the retreat commenced, while Julian and his victorious army were still encamped in sight of Ctesiphon, the Persian king, according to some writers, sent an embassy proposing terms of peace. Julian’s successes are represented as having driven Sapor to despair--“the pride of his royalty was humbled in the dust; he took his repasts on the ground; and the grief and anxiety of his mind were expressed by the disorder of his hair.” He would, it is suggested, have been willing “to purchase, with one half of his kingdom, the safety of the remainder, and would have gladly subscribed himself, in a treaty of peace, the faithful and dependent ally of the Roman conqueror.” Such are the pleasing fictions wherewith the rhetorician of Antioch, faithful to the memory of his friend and master, consoled himself and his readers after Julian’s death. It is difficult to decide whether there underlies them any substratum of truth. Neither Ammianus nor Zosimus makes the slightest allusion to any negotiations at all at this period; and it is thus open to doubt whether the entire story told by Libanius is not the product of his imagination. But at any rate it is quite impossible that the Persian king can have made any abject offers of submission, or have been in a state of mind at all akin to despair. His great army, collected from all quarters, was intact; he had not yet condescended to take the field in person; he had lost no important town, and his adversary had tacitly confessed his inability to form the siege of a city which was far from being the greatest in the empire. If Sapor,
