Babur's first active operation in the field was to dispatch a force to the relief of Sambhal a district lying beyond the Ganges in what is now called Rohilkhand. It was held by Kasim Sambhali who had formerly shown himself hostile to Babur but was glad to solicit his aid when at this time besieged in his chief town by Malik Baban Jilwani.[citation needed] This powerful and active Pathan chief had joined Babur after he had passed Sirhind but subsequently left him under circumstances which are not clear, but he probably was not satisfied with his reception as Babur complains with the bitterness of his presumption and pretensions and of the rudeness and stupid forwardness of the Pathans in general.[citation needed] However that may be, Baban had withdrawn himself from Babur's camp had collected an army and now besieged Kasim in Sambhal which he had discovered was ill garrisoned. Kasim reduced to the last extremity applied to Babur for assistance.[citation needed] The Emperor dispatched Hindu Baig with a body of Turks-Mughals along with Sheikh Kuren and his Doab Turkishbunds to his succor.[citation needed]
