[6] Resistance against invasion into what is present-day Bangladesh in particular (and that of Sylhet especially) was headed both jointly and independently by Bayazid, Khwaja Usman of Usmangarh (and Taraf) and Anwar Khan of Baniachong.
[9] It was in light of this close alliance that Islam Khan I, the Mughal governor of Bengal, when initiating hostilities against Khwaja Usman in March 1612, also dispatched an imperial force against Bayazid so as to prevent the latter from providing aid.
[14] Upon reaching the outskirts of Bayazid's domains, the Mughals launched a series of plundering raids with the intention of terrorising the inhabitants into submission, eventually arriving on the banks of the Surma River just outside the city of Sylhet.
However, upon receiving considerable reinforcements from the Raja of Kachar, Bayazid and Yaqub resumed their hostilities, attacking the imperial fort to the result of a serious loss of life on both sides.
The Afghans reached such levels of confidence that they repeatedly sent messages offering to accept the Mughals' surrender: "we still promise you and all your comrades, great and small, a safe passage.
When Emperor Jahangir ordered the presence of Bayazid and his family alongside Khwaja Usman's at the imperial court, the former group were escorted by Mutaqid Khan.
[19][20] While historian Abdul Karim states that nothing more is heard of Bayazid after this, Syed Murtaza Ali asserts that he was allowed by the Emperor to continue to rule Pratapgarh as a feudal lord, before dying soon after.
