Firishta's History (Gulshan-i Ibrāhīmī) 62.2.3

62.2.3

Kamran Mirza hearing of a caravan passing, in which was a number of fine horses, he detached Sheer Ally Beg with a strong party to seize and bring it into the city. Hoomayoon gained intelligence of this design, and marched round the walls, to cut off Sheer Ally Beg's retreat, who was attacked and defeated with great loss. In this state of affairs, the Prince Sooliman Mirza from Budukhshan, Alugh Mirza, and Kasim Hoossein Sooltan, with several officers detached by Beiram Khan, the governor of Kandahar, as reinforcements, joined Hoomayoon, while Kurrachar Khan and Ooloos Beg, having deserted from the city, joined his army. Kamran Mirza, exasperated at the defection of these two officers, murdered the three sons of Ooloos Beg, and threw their mangled bodies over the walls; he also bound Kurrachar Khan's only son to a stake, and exposed him on the battlements. Hoomayoon gave his brothers to understand that if they put Kurrachar Khan's son to death, they should both suffer the same fate if taken. Kamran was in consequence deterred from his intended cruelty, and on that very night he evacuated the place, and fled towards the hills, leaving Hoomayoon a second time at liberty to take quiet possession of Kabul. On his retreat, Kamran Mirza was plundered and stripped of his very clothes by the Hazaras; but when they knew him, they conducted him in safety to Ghorebund.
