explains that "The loyalties of [officials and their armed contingents] seem to have been motivated more by their own interests, the closeness of the family relation and above all the charisma of the pretenders than by ideological divides." Muslims and Hindus did not divide along religious lines in their support for one pretender or the other nor, according to Chandra, is there much evidence to support the belief that Jahanara and other members of the royal family were split in their support. Jahanara, certainly, interceded at various times on behalf of all of the princes and was well-regarded by Aurangzeb even though she shared the religious outlook of Dara. In 1656, a general under Qutb Shahi dynasty named Musa Khan led an army of 12,000 musketeers to attack Aurangzeb, who was besieging Golconda Fort. Later in the same campaign, Aurangzeb, in turn, rode against an army consisting of 8,000 horsemen and 20,000 Karnataki musketeers. Having made clear that he wanted Dara to succeed him, Shah Jahan became ill with stranguary in 1657 and was closeted under the care of his favourite son in the newly built city of Shahjahanabad (Old Delhi). Rumours of the death of Shah Jahan abounded and the younger sons were concerned that Dara might be hiding it for Machiavellian reasons. Thus, they took action: Shah Shuja In Bengal, where he had been governor since 1637, Prince Muhammad Shuja crowned himself King at RajMahal, and brought his cavalry, artillery and river flotilla upriver towards Agra. Near Varanasi his forces confronted a defending army sent from Delhi under the command of Prince Sulaiman Shukoh, son of Dara Shukoh, and Raja Jai Singh while Murad did the same in his governorship of Gujarat and Aurangzeb did so in the Deccan. It is not known whether these preparations were made in the mistaken belief that the rumours of death were true or whether the challengers were just taking advantage of the situation. After regaining some of his health, Shah Jahan moved to Agra and Dara urged him to send forces to challenge Shah Shuja and Murad, who had declared themselves rulers in their respective territories. While Shah Shuja was defeated at Banares in February 1658, the army sent to deal with Murad discovered to their surprise that he and Aurangzeb had combined their forces, the two brothers having agreed to partition the empire once they had gained control of it.
