The confederates, however, unable to reduce Samarkand that year, returned home for the winter, having agreed to make great preparations for another campaign. Both Kings accordingly, in the year 902, in the beginning of the spring, took the route of Samarkand. Sooltan Ally Mirza having reached Samarkand first, Baesanghar advanced, and encamped without the city walls, but upon Babur's arrival, he retreated within the town. In the night, Altoon Khwaja, who was going the rounds of Babur's camp, having discovered the retreat of Baesanghar Mirza, fell upon his rear, and put a great number of his people to the sword. Meanwhile Babur captured the fort of Asheera, situated at a small distance from the city, and invested Samarkand: this town was defended with bravery till the autumn, when the allies were compelled to raise the siege, and retire; Sooltan Ally Mirza returning to Bokhara, and Babur to Khwaja-Deedar, to pass the winter. In this state of affairs, Baesanghar Mirza sought an alliance, and requested assistance from Sheebany Khan, ruler of Toorkistan, who, avoiding Khwaja-Deedar, the winter-quarters of Babur, proceeded direct to Samarkand. Sheebany Khan and Baesanghar Mirza having quarrelled soon after, the former returned to his own country. This circumstance so much embarrassed the affairs of Baesanghar Mirza, that proceeding with a small retinue of 300 horse, he went in person to solicit the assistance of Khoosrow Shah, ruler of Koondooz.
