Diler Khan Daudzai was a Mughal general who served under Aurangzeb and was the governor of Awadh.

[4] He was born near Peshwar,[5][6] and was son of Nawab Darya Khan Rohilla, an Afghan who traced his descent to the Pashtun Daudzai tribe,[7] and a mansabdar who served under the Indian Muslim Mir Bakhshi, Shaikh Farid Bukhari in 1603.

So he sent Jai Singh, along with Diler Khan to overthrow the Marathas and establish Mughal rule in the Deccan.

But Mirza Jai Singh, being a shrewd and experienced general, knew that hoisting the Mughal flag on Purandar will not be easy.

The Mughal army under Diler Khan and Jai Singh celebrated the victory over Vajragarh with booming of guns.
