Firishta's History (Gulshan-i Ibrāhīmī) 225.1.5

225.1.5

His first object was Islamabad, where he was met, at the distance of four miles, by Taj Khan, whose force formed a junction with the minister's army, and measures were taken to commence regular approaches against the fort; but owing to the deference Azim Hoomayoon always evinced towards the descendants of his patron Sooltan Hooshung, he sent some of the most respectable of his officers into the fort, in order to induce the Prince Ahmud to accommodate matters, but without effect. Kowam Khan, who also joined the King’s army at this place, but who was secretly in league with the Prince Ahmud, privately furnished the garrison with stores; and the siege might have been protracted indefinitely, had not Azim Hoomayoon bribed one of his servants to administer poison to the Prince in a cup of wine, of which he died. Azim Hoomayoon instantly took possession of the fort without resistance, and marched to Hooshungabad; but Kowam Khan, suspecting that his treachery had been discovered, remained at Bhilsa, while Azim Hoomayoon continued his march. On his arrival at Hooshungabad, Azim Hoomayoon found that Mullik Itihad, afraid to oppose the King’s army, had fled to the foot of the Gondwana hills, where the inhabitants seized and put him to death. After having occupied Hooshungabad with the King’s troops, and placing a confidential officer in charge, Azim Hoomayoon proceeded to Chundery. On arriving within a few miles of the place he was met by Noosrut Khan, who threw himself on his mercy.
