On Monday, the 1st Rajab, 644 H., the army set forth and proceeded to the river Sodra. Here Ulugh Khan was detached with several nobles and generals to make an incursion into the hills of Jud.

Ulugh Khan accordingly attacked the hills of Jud, and the countries on the Jailam, and led his forces as far as the banks of the Indus. All the women and dependants of the infidels which were in those parts were obliged to flee, and a party of the Mughal army crossed over the Jailam, and saw the forces which were arrayed under the command of Ulugh Khan. The manifold lines of the army, the numbers of the horse, the armour and the arms, filled the observers with wonder and dismay. The bravery and generalship which Ulugh Khan displayed in scaling the mountains, breaking through defiles, capturing fortified places, and crossing jungles, cannot be described in writing.
