and the King in person, cutting off their retreat to the fort, compelled them to fly to the mountains. The fort of Birhala, in which was considerable treasure, fell, without further opposition, to Babur; in which having left Mahomed Ally, he returned to Kabul. In the latter end of the same year, Babur returned a second time towards Hindoostan, in order to reduce Lahore. On the route, he defeated the Yoosoofzye Afghans, who endeavoured to oppose his progress. On reaching Pishawur, he caused that fort to be repaired, and proceeded to the Indus. Intelligence was now brought that Sooltan Syeed, the King of Kashghar, was in full march towards Budukhshan, which induced Babur to return. At the same time he left Mahomed Sooltan Mirza, Bin Sooltan Ooveis, Bin Kirany, Bin Munsoor, Bin Oomr Sheikh, Bin Ameer Teimoor, with 4000 horse, to prosecute the war in the East. Babur had scarcely reached Kabul, when he learned that the King of Kashghar had retreated. His attention being directed to the Afghans of the tribe of Khizr Kheil, who had made depredations on Kabul during his absence, he entered and sacked their country, and returned to his capital.
