In the summer of 1818, Sir Thomas Hislop’s army concentrated its efforts on subduing the Khandesh region. They encountered the fortress of Thalner, strategically located along the Tapi River, which appeared to be in a relatively poor state of repair. Thalner was once quite important, as for a time from 1382, it served as the first capital of the powerful regional dynasty, the Faruqi Kings.
On July 27, 1818, Hislop’s men over-confidently stormed the fort, but found themselves in a trap, resulting in the death of several men, including senior officers. The British eventually took the fortress and proceeded to murder the entire garrison of 300 men, hanging its killedar from a tree. This act of barbarity was against all the rules of war. Governor-General Lord Moira was disgusted by this crime, in addition, to rumors that Hislop had personally looted massive quantities of treasure from the region known as the “Deccan Prize”. At his instigation, Hislop was eventually removed from his command, although he faced no further penalty.
