Firishta's History (Gulshan-i Ibrāhīmī) 6.2.4

6.2.4

Mahmood having next morning invested the fort of Bhateea, took measures to fill up the ditch, an undertaking which in a few days was nearly completed. Beejy Ray, deeming it impossible any longer to maintain the town, determined to leave only a small garrison for its defence; and, accordingly, one night, marched out with the rest of his troops, and took post in a wood on the banks of the Indus. Mahmood, informed of his retreat, detached part of his army to surprise him. Beejy Ray, deserted by most of his friends, and perceiving himself surrounded by the Mahomedans, attempted in vain to force his way, till, just as he was on the point of being made prisoner, he turned his sword against his own breast; and most of his adherents subsequently fell, in attempting to revenge the death of their master. Mahmood, mean time, took Bhateea by assault. Two hundred and eighty elephants, many slaves, and other spoils, were obtained in the town; which Mahmood annexed, with its dependencies, to his own dominions and returned victorious to Ghizny.
