Firishta's History (Gulshan-i Ibrāhīmī) 46.3.3

46.3.3

While the armies were encamped near each other, Mahmood Toghluk, dissatisfied with his situation, and imagining that Ibrahim Shah would acknowledge him King, and abdicate the throne of the Shurky provinces in his favour, left the camp while on a hunting excursion, and repaired to the army of Ibrahim Shah. When that Prince discovered the expectations of his guest, he even withheld from him the necessaries of life, and intimated to him to quit the camp. Mahmood returned in great distress to Kunowj, and was left by Mulloo Yekbal Khan in the government of that city, having previously expelled the governor, who occupied it on the part of Ibrahim Shah. Ibrahim Shah Shurky did not resent this insult, but permitted Mahmood Toghluk to occupy Kunowj, and himself returned to Joonpoor, while Mulloo Yekbal Khan retreated to Dehly. In the year 805, Mulloo Yekbal Khan marched against Gualiar, which had fallen into the hands of Nursing Ray during the invasion of Teimoor, and which had lately on Nursing Ray's death descended to his son, Brahma Dew. The fort being strong, he found he could effect nothing against it at that time, except plundering the districts around. He accordingly returned to Dehly, but the latter was eventually obliged to raise the siege, and content himself with devastating the country, and returned to Dehly.
