46.4.6

In the year 821, Khizr Khan having sent his minister against Nursine Ray, the Raja of Kutehr, he plundered and laid waste that district, and proceeding to Budaoon, crossed the river at Etawa, on which place he imposed a contribution, and returned to Dehly. Khizr Khan subsequently marched in person to Kutehr, and on his route he attacked and defeated a formidable band of plunderers at Kole; he then crossed the Ganges, and having laid waste the country of Sumbhul and Kutehr, returned to his capital. After remaining at Dehly only a few days, he moved towards Budaoon. Mohabut Khan, governor of Budaoon, alarmed at his approach, shut himself up in the fort, to which the King laid siege for six months. In the course of the operations, Khizr Khan discovered that Kowam Khan, Yekhtyar Khan Lody, and several of the old friends of the late King, Mahmood Toghluk, had formed a conspiracy against his life. This circumstance induced him to raise the siege of Budaoon, and to retire to Dehly, where on the 20th of Jumad-ool-Awul, 822, having assembled the conspirators, he ordered his household troops to fall upon them, and put them to death.
