Eastern Afghanistan Operations was when Uzbek Khan and Muhammad Shaybani surrounded Kandahar, Babur found his developing Kingdom of Kabul in danger.
Babur's second Indian expedition (as considered by many Muslim historians, including Abu'l-Fazl ibn Mubarak), became an operation monitoring Kabul, traveling around eastern provinces of Afghanistan to subdue rebellious Afghans and plunder towns and villages for supplies for his army's survival.
Kafirs had posted some men in a breastwork on a commanding eminence in the valley of Birain and they descended rapidly from the hill and began to fire arrows.
Having wounded Puran, son-in-law of Qasim Bayg, they were on the verge of coming up to him and taking him prisoner when the rest of his party made a push to drive out the enemy, and rescued him.
At that time Mukim Beg Arghun's daughter Mah Chuchak, was married to Qasim Kokaltash (later wife of Shah Hassan) in the Mendraur.
It was at this time that Babur found it inexpedient to proceed in his expedition to India and sent back Mullah Baba Beshagheri with a few troops towards Kabul.
