Foiled in his hopes of persuading the fickle but powerful Rajput feudatory, Maharaja Jaswant Singh of Marwar, to support his cause, Dara Shikoh decided to make a stand and fight Aurangzeb's relentless pursuers but was once again comprehensively routed in the battle of Deorai (near Ajmer) on 11 March 1659. After this defeat he fled to Sindh and sought refuge under Malik Jiwan (Junaid Khan Barozai), an Afghan chieftain, whose life had on more than one occasion been saved by the Mughal prince from the wrath of Shah Jahan. However, Junaid betrayed Dara Shikoh and turned him (and his second son Sipihr Shikoh) over to Aurangzeb's army on 10 June 1659. Dara Shikoh was brought to Delhi, placed on a filthy elephant and paraded through the streets of the capital in chains. Dara Shikoh's fate was decided by the political threat he posed as a prince popular with the common people – a convocation of nobles and clergy, called by Aurangzeb in response to the perceived danger of insurrection in Delhi, declared him a threat to the public peace and an apostate from Islam. He was assassinated by four of Aurangzeb's henchmen in front of his terrified son on the night of 30 August 1659 (9 September Gregorian). After death the remains of Dara Shikoh were buried in an unidentified grave in Humayan's tomb in Delhi. On 26 February 2020 the government of India through Archaeological Survey of India decided to find the burial spot of Dara Shikoh from the 140 graves in 120 chambers inside Humayun's Tomb. It is considered a difficult task as none of the graves are identified or have inscriptions. Niccolao Manucci, the Venetian traveler who worked in the Mughal court, has written down the details of Dara Shikoh's death. According to him, upon Dara's capture, Aurangzeb ordered his men to have his head brought up to him and he inspected it thoroughly to ensure that it was Dara indeed. He then further mutilated the head with his sword three times. After which, he ordered the head to be put in a box and presented to his ailing father, Shah Jahan, with clear instructions to be delivered only when the old King sat for his dinner in his prison. The guards were also instructed to inform Shah Jahan that, "“King Aurangzeb, your son, sends this plate to let him (Shah Jahan) see that he does not forget him”."
