56.4.7

On the 1st of Mohurram, A.H. 911, Kootloogh Nigar Khan, the mother of Babur, died at Kabul. In this year also the inhabitants of Kabul were thrown into great consternation by dreadful earthquakes, which laid many cities in ruins. Babur endeavoured to alleviate the public calamity in such a manner by his unwearied care and extensive benevolence, that he gained the love and attachment of his new subjects. The ambition of Babur, however, could not rest; he accordingly led an army against the Arghoons, and having deprived them of the strong fort of Kilat, established an alliance with Buddee-ooz-Zeman Mirza. He marched in the same year to the Kishlakat-i-Huzara, the inhabitants of which he brought into subjection, and conferred the government of Ghizny on his brother Jehangeer; but after some time, the latter, quitting Ghizny without permission, came to Kabul, and on meeting with a reproof from Babur, he departed suddenly, and proceeded into the Kishlakat-i-Huzara. In the year 912, Babur marched towards Khorassan to join Sooltan Hoosseim Mirza, who, ashamed of his former behaviour, and irritated by fresh injuries from Sheebany Khan, now proposed to Babur, that they should unite in alliance against the Oozbuks. On the road, however, he was induced to return to take measures against Jehangeer Mirza.
