57.3.1

On the return of Hoomayoon to his capital, it was observed, that he gave way more than ever to the excessive use of opium: public business was neglected; and the governors of the surrounding districts, taking advantage of the state of affairs, promoted their own aggrandizement. In the first place, Sooltan Jooneid Birlas dying, the Afghans of the late Shurky kingdom, whom he had kept in subjection, revolted, and enlisted under the standard of Sheer Khan Soor. This event compelled Hoomayoon to march towards Joonpoor on the 8th of Suffur, A.H. 943. He was succeeded Khan had gone to Bengal, the King proceeded to besiege the fort of Chunar, which held out, under the command of Ghazy Khan Soor, for six months. The place was, however, eventually taken, owing to the skill of Roomy Khan (the late commander of Bahadur Shah's artillery), now in the service of Hoomayoon. Having ascertained the strength of the fort on the land side, Roomy Khan determined to attack it from the river Ganges. He accordingly erected stages of a certain height, placed on rafts, which being built at some distance above the fort, were launched, and floated down without resistance: the walls being low, they were easily surmounted, and the place was thus secured. Previously to this event, Hoomayoon had marched on with the main body of the army. Sheer Khan Soor, meanwhile, had wrested the kingdom of Bengal from Mahmood Shah Poorby, who, having been severely wounded, reached the King's camp.
