Firishta's History (Gulshan-i Ibrāhīmī) 46.3.6

46.3.6

In the month of Zeekada, of the same year, Mahmood Toghluk marched against Mullik Meer Zeea, who, on the part of Ibrahim Shah Shurky, was governor of Birun. Mullik Meer Zeea opposed him without the walls, but was defeated, and compelled to retire within the works. The King's troops followed the fugitives so closely, that they entered the place together, and Mullik Meer Zeea fell in the assault. From Birun the King marched to Sumbhul; but Tartar Khan fled at his approach, and went to Kunowj. The King, leaving Assud Khan Lody at Sumbhul, returned to Dehly. In the year 811, Mahmood Toghluk marched against Kowam Khan, who occupied Hissar Feroza, on the part of Khizr Khan. The King, after levying contributions, returned; but Khizr Khan, on hearing what had occurred, marched, by the route of Rohtuk, against Dehly. Mahmood, deficient both in sense and courage, allowed himself to be patiently besieged in that part of the city known by the name of Ferozabad. Khizr Khan, however, being in want of forage and grain, was soon obliged to raise the siege, and retire to Futtehpoor, but in the beginning of the year 814 he returned by the route of Rohtuk to Futtehpoor. This place was then in possession of two of Mahmood Toghluk's officers, Mullik Idrees and Moobarik Khan, who declined hostilities, and submitted. Khizr Khan, having plundered the town of Narnoul, again advanced to Dehly. On this occasion, Mahmood shut himself up in the old citadel of Siry, to which Khizr Khan laid siege.
