Maʾathir-i Jahangiri 2: Twenty-first Year of the Reign.

2

[When the Prince Shah Jahan heard of the rebellious proceedings of Mahabat Khan, he resolved that he would hasten immediately to the Emperor his father, although he was unprepared for war, and was in a very feeble state of health. He stated his design to Khan Jahan and to Raja Nar Singh Deo, and endeavoured to gain their support; but they did not incline to his proposals, and made excuses. The Prince put his trust in God, and started with a small force from Nasik, trusting that he might find assistance on the road, and collect a force. He passed through the pass of Chanda, although Prince Parwez, with all the Imperial army, was at Burhanpur. Passing about twenty kos from Burhanpur, he crossed the Nerbadda, in the territory of Mandu. Upon reaching Ajmir, Raja Kishan Singh, son of Raja Bhim, who had accompanied him from Nasik with 500 horse, was taken ill, and died. His followers then dispersed. Only 400 or 500 men then remained with the Prince, and with such a small force it was impossible for him to carry out his design of going to the Emperor. It then occurred to him that he would go to Thatta, which is in a remote corner, and there wait patiently for a while. From Ajmir he proceeded to Nagor, and from thence to Joudhpur. From thence he travelled to Thatta by the route which the Emperor Humayun had fled to Sind when driven from his throne. This route was very arid and destitute of water, and his journey was attended with great hardship. When he reached the country of Thatta, Sharif Mulk, who held the place for Prince Shahriyar, did his best to put the town in a state of defence, and the Prince was thwarted in his designs by obstacles which it would be tedious to relate.
He was greatly affected by his ill-success, and many of his most devoted followers were disabled. Just at this time a letter reached him from Nur Jahan, informing him that his march had alarmed Mahabat Khan, whose forces had been driven away and dispersed, and that the Prince had better return to the Dakhin, and await a change of fortune. The advice of the Begam seemed good, so the Prince determined to return to the Dakhin by way of Gujarat.]
