After that Shir Shah reached the hill-country of Balnat. He built there the fortress of Rohtas as a protection for the army of Hindustan against the Mughul forces. Then he appointed Khawass Khan to undertake the pursuit, and returned. While on the march he heard that a commander named Khizr Khan Sarak had become infatuated with rebellious notions and was behaving as though he were a Sultan. Shir Shah accordingly bent his course thither, and Khizr Khan hastening to encounter him was taken prisoner. Shir Shah took possession of that country and conferred it by way of jaegir upon several of his Amirs, and appointed to the superintendence of the fort of Rohtas, Qazi Fazilat the Qazi of the army, who was popularly known by the more appropriate title of Qazi Fazihat.
