He was not unmolested in his retreat.

Bahram no sooner heard of his flight than he sent off a body of 4000 horse, with orders to pursue and capture the fugitive.

They would have succeeded, had not Bindoes devoted himself on behalf of his nephew, and, by tricking the officer in command, enabled Chosroes to place such a distance between himself and his pursuers that the chase had to be given up, and the detachment to return, with no more valuable capture than Bindoes, to Ctesiphon.
Chosroes was received with all honor by Probus, the governor of Circesium, who the next day communicated intelligence of what had happened to Comentiolus, Prefect of the East, then resident at Hierapolis.

At the same time he sent to Comentiolus a letter which Chosroes had addressed to Maurice, imploring his aid against his enemies.

Comentiolus approved what had been done, despatched a courier to bear the royal missive to Constantinople, and shortly afterwards, by the direction of the court, invited the illustrious refugee to remove to Hierapolis, and there take up his abode, till his cause should be determined by the emperor.
