his safety. He destroyed, in a single hour, the whole navy, which had been transported above five hundred miles, at so great an expense of toil, of treasure, and of blood. Twelve, or, at the most, twenty-two small vessels were saved, to accompany, on carriages, the march of the army, and to form occasional bridges for the passage of the rivers. A supply of twenty days' provisions was reserved for the use of the soldiers; and the rest of the magazines, with a fleet of eleven hundred vessels, which rode at anchor in the Tigris, were abandoned to the flames, by the absolute command of the emperor. The Christian bishops, Gregory and Augustin, insult the madness of the Apostate, who executed, with his own hands, the sentence of divine justice. Their authority, of less weight, perhaps, in a military question, is confirmed by the cool judgment of an experienced soldier, who was himself spectator of the conflagration, and who could not disapprove the reluctant murmurs of the troops. Yet there are not wanting some specious, and perhaps solid, reasons, which might justify the resolution of Julian. The navigation of the Euphrates never ascended above Babylon, nor that of the Tigris above Opis. The distance of the last-mentioned city from the Roman camp was not very considerable: and Julian must soon have renounced the vain and impracticable attempt of forcing upwards a great fleet against the stream of a rapid river, which in several places was embarrassed by natural or artificial cataracts. The power of sails and oars was insufficient; it became necessary to tow the ships against the current of the river; the strength of twenty thousand soldiers was exhausted in this tedious and servile labor, and if the Romans continued to march along the banks of the Tigris, they could only expect to return home without achieving any enterprise worthy of the genius or fortune of
