Firishta's History (Gulshan-i Ibrāhīmī) 57.3.8

57.3.8

Kootub Khan, with a great part of his army, was cut off, and that chiefs head was sent to Agra. The generals, at the same time, recommended the King immediately to assume the command of the army in person. Hoomayoon accordingly marched with a hundred thousand horse, and crossing the Ganges, near Kunowj, encamped for a whole month in view of Sheer Khan's army, which consisted of only fifty thousand men. Meanwhile, Mahomed Sooltan Mirza and his sons, who were alike distinguished for their treachery and ingratitude, went over to the enemy with all their adherents. Many others were induced also to follow them; an event which again plunged the King into distress; for his army, thus dispirited, began to desert by thousands. To complete his misfortunes, too, the rainy season commenced; his camp became quite overflowed, insomuch that he was obliged to abandon his position, and move to a more exposed one on higher ground. On the 10th of Mohurrum, 947, while his army was in motion, he was attacked by Sheer Khan, and sustained a signal defeat. Having unfortunately, as in the former action, the river close on his rear, some thousands of his soldiers, in avoiding the swords of the enemy, suffered a more ignominious fate in the stream. A few only escaped with the King across the river, with whom he fled to Agra. Sheer Khan lost no time in pursuing Hoomayoon, who was forced to retreat to Lahore.
