Meanwhile Ismael Khan, Ghazy Khan, and Futteh Khan Bulloch, governors of the several provinces in Punjab, acknowledged the title of Sheer Shah. In his progress through that province, having observed among the mountains of Nandere and Bulnat a hill well calculated for defence, he ordered a fortress to be constructed on it, which he named Rohtas. Khowas Khan, to whose bravery and conduct he felt himself deeply indebted, was created Sipasalar (commander of his forces), and a tenth of the revenues of Punjab was assigned to him, of which province he was appointed governor. Heibut Khan Neeazy remained in command of the army in the north-west, while Sheer Shah returned towards Agra. On his arrival he learned that Khizr Khan Sheerwany, whom he had left in the government of Bengal, had espoused the daughter of the exiled King, Mahomed Shah Poorby, and had assumed the state of a sovereign prince. Aware of the danger of permitting such conduct, Sheer Shah proceeding to Bengal, Khizr Khan submitted without a struggle, and was imprisoned. Sheer Shah now divided the kingdom of Bengal among a number of chiefs wholly independent of each other, and appointing Kazy Fuzeelut, a native of Kurra, famous for his learning as well as for his wisdom, to control the whole, he returned to Agra. In the year 949, Sheer Shah marched towards Malwa.
