Firishta's History (Gulshan-i Ibrāhīmī) 32.1.4

32.1.4

In the month of Shaban, 645, Nasir-ood-Deen Mahmood proceeded with his troops through the country which lies between the rivers Ganges and Jumna, and, after an obstinate siege, the fort of Bitunda yielded to his arms. He then continued his march towards Kurra, Gheias-ood-Deen Bulbun commanding the vanguard. He was met at Kurra by the Rajas Dulky and Mulky, whom he defeated and plundered, taking many of their families prisoners. These two Rajas had seized all the country to the south of the Jumna, and had destroyed the King's garrisons from Malwa to Kurra. They resided at Kalunjur. After these exploits Nasir-ood-Deen returned to Dehly.
