Firishta's History (Gulshan-i Ibrāhīmī) 93.2.6

93.2.6

It will hardly be credited that the city of Beejapoor, which had been invested for twelve months by the united armies of the confederate sovereigns of Berar, Ahmudnuggur, and Golconda, and during which time a large breach was made in the city walls, and the garrison within mutinous, while the kingdom was in a state of anarchy : it will not be believed, I say, that, under such circumstances, the Beejapoor monarchy should have been saved by the exertions of one man. This person was Shah Abool Hussun, who in the course of two or three months brought together an army of twenty thousand horse, and in one month afterwards not only attacked the enemy, and raised the siege, but even pursued the army of one of the confederates to the very gates of his capital, and took from him, among other spoils, no fewer than one hundred and fifty elephants. On the return of Dilawur Khan from his successful expedition against the Kootb Shahy troops, he became so elated that he aspired to the office of minister. To attain this end, he gained over Heidur Khan, the commandant of the citadel of Beejapoor, wherein the King resided, and resolved to seize the minister Yekhlass Khan. Every thing being ripe for the execution of his design, he marched expeditiously to the capital, and encamping near the Allapoor gate, sent in such flattering messages and declarations of attachment to Yekhlass Khan as threw him off his guard, and rendered him neglectful of the security of the city and palace.
