57.2.2

Three days after the capture of Mando, Hoomayoon renewed the pursuit of Bahadur Shah. who, having taken all his treasure and jewels out of the city of Champanere, fled towards Ahmudabad. The city of Champanere, however, was devoted to plunder, while the reduction of the citadel (which still held out) being left to Dowlut Khwaja Birlas, Hoomayoon continued in pursuit of the King of Guzerat. Bahadur Shah, hearing of the approach of the Moguls, fled to Cambay in the first instance, and eventually to the island of Dew. He was pursued so closely by Hoomayoon, that he arrived at Cambay on the very evening Bahadur Shah left it. Hoomayoon, however, having heard that Bahadur Shah's wealth was principally in the citadel of Champanere, he returned to superintend the siege of that place. Yekhtyar Khan, of Guzerat, defended the fort with great bravery; yet, though he had some years' provision in the fort, still, with that propensity to accumulate which belongs to some men, he was desirous of obtaining more, and was in the habit of receiving supplies daily by a secret pathway, leading through a thick wood. Hoomayoon, while one day reconnoitring, suspecting this fact, seized a party of country people who conveyed the supplies, and induced them to carry him, in disguise, to the spot where they gained admittance. After making the necessary observations, he returned to his camp.
