Sambhaji Maharaj and his men were captured by Muqarrab Khan and his Mughal contingent of 25,000 soldiers. Sambhaji Maharaj was presented before the Mughal Emperor Aurangzeb. Sambhaji dared Aurangzeb in open court and flatly refused to surrender the Maratha kingdom. A panel of Qadis of the Mughal Empire indicted and sentenced Sambhaji to death.
