Quitting Babylon, he marched into Media, and being met by the pretender near a town called Kudrus, he defeated him in a great battle.
This is no doubt the engagement of which Herodotus speaks, and which he rightly regards as decisive.

The battle of Kudrus gave Ecbatana into the hands of Darius, and made the Median prince an outcast and a fugitive.
He fled towards the East, probably intending to join his partisans in Hyrcania and Parthia, but was overtaken in the district of Rhages and made prisoner by the troops of Darius.

The king treated his captive with extreme severity.

Having cut off his nose, ears, and tongue, he kept him for some time chained to the door of his palace, in order that there might be no doubt of his capture.

When this object had been sufficiently secured, the wretched sufferer was allowed to end his miserable existence.
