49.1.7

And in the month of Shawwāl in the aforesaid year Iqbāl Khān, who is better known as Malloo, swore many oaths of allegiance to Sultān Nasrat Shāh, whom he deported to the fortress of Jahān-numā, taking him away with elephants and an armed force; and Sultān Mahmūd and Muqarrab Khān and Bahādur Nāhir shut themselves up in old Dihlī. On the third day from this Iqbāl Khān made a sudden attack in strong force upon Nusrat Shāh hoping to take him by surprise; Nusrat Shāh fled from Jahān-numā and came to Fīrūzābād, and leaving there crossed the Jamna and went to join Tātār Khān his Vazīr at Pānīpath. The whole of the army and elephants of Nusrat Shāh fell into the hands of the astute Iqbāl Khān, and for two whole months daily battles were fought between Muqarrab Khān and Iqbāl Khān, until by the intervention of certain Amīrs peace was established between these two leaders; but after a few days Iqbāl Khān proceeded against Muqarrab Khān, and without warning suddenly surrounded him and besieged him; and after giving him assurances of safety raised him to the dignity of martyrdom, and getting Sultān Mahmūd into his power made a puppet of him and took the management of the state into his own hands. Then in the month of Zū Qa'dah of the aforesaid year Iqbāl Khān wrested Pānīpath by force from the followers of Tātār Khān, and seized all his baggage and his elephants and army.
