This success enabled Abu Sa'id Mirza to turn his undivided force to complete the destruction of Juki Mirza.[2] He besieged that prince in Shahrukhiya, a strong and populous city on the Syrdarya, and after a siege of one year Khwaja Ubaydullah Ahrar negotiated a surrender.[2] Abu Sa'id Mirza took the city and he spared its inhabitants.[2] He treated his captor Juki Mirza with respect in Shahrukhiya and Samarkand. But in January 1464 he was transferred to Qila Ikhtiyar-al-Din in Herat where he died in that year.[2]
