Chosroes was forced to fly.

He fell back on Ctesiphon; but despairing of making a successful defence, with the few troops that remained faithful to him, against the overwhelming force which Bahram had at his disposal, he resolved to evacuate the capital, to quit Persia, and to throw himself on the generosity of some one of his neighbors.

It is said that his choice was long undetermined between the Turks, the Arabs, the Khazars of the Caucasian region, and the Romans.

According to some writers, after leaving Ctesiphon, with his wives and children, his two uncles, and an escort of thirty men, he laid his reins on his horse's neck, and left it to the instinct of the animal to determine in what direction he should flee.

The sagacious beast took the way to the Euphrates; and Chosroes, finding himself on its banks, crossed the river, and, following up its course, reached with much difficulty the well-known Roman station of Circesium.
