Firishta's History (Gulshan-i Ibrāhīmī) 47.2.5

47.2.5

The reinforcements having joined, the King remained on the Soorsutty river, and detached the greatest part of his army to invest the fort of Surhind. The rebel Folad now sent a message to the King, saying, that if Imad-ool-Moolk were sent to him, with a promise of pardon, he would deliver up the place. This measure was acceded to on the King's part; and Folad having met Imad-ool-Moolk without the gate was assured of the King's pardon, and promised, on his part, to surrender the fort of Surhind on the next day. One of Imad-ool-Moolk's attendants, being acquainted with Folad, hinted to him privately, that though Imad-ool-Moolk was a man of honour, and would certainly adhere to his promise, yet the King might not be so scrupulous. Folad's suspicions were raised, and having abundance both of money and supplies in the place, he determined to hold out to the last. The King, finding the reduction of the place would occupy time, and thinking so large an army unnecessary for the siege, permitted Imad-ool-Moolk to return to his government of Mooltan; and leaving Islam Khan Lody, Kalu Khan, and Ray Feroze, with some Ameer Judeeda, to conduct the siege, the King retired to Dehly. Folad held out six months: he was greatly distressed; and saw no means of extricating himself but by an alliance with Ameer Sheikh Ally, governor of Kabul, on the part of Sharokh Mirza. He accordingly despatched messengers to him, soliciting his aid.
