56.6.3

In the year 926, Babur marched a third time towards India, attacking the Afghans on his route. On reaching Sealkote the inhabitants submitted, and thus saved their property from plunder: not so the people of Syudpoor, who making a vigorous defence, the garrison was put to the sword, and their families carried into captivity. Babur was here met by intelligence of an army from Kandahar having invaded the territory of Kabul; abandoning, therefore, his projects in India, he returned to his capital, and not only expelled the invaders, but pursued them, and laid siege to Kandahar. In the mean time he received advice of the death of Khan Mirza, in Budukhshan, in whose stead Babur appointed his son Hoomayoon governor. Shah Beg Arghoon, of Kandahar, maintained the siege with great obstinacy for three years; but in the year 928, Kandahar fell, as well as all the country of Gurmseer, into Babur's hands. The Prince Kamran Mirza, Babur's second son, was placed in charge of the government. Shah Beg Arghoon being thus compelled to seek safety in flight, retreated with a few of his tribe, and found refuge in the city of Bhukkur, the capital of Sind.
