The Marathas besieged Kumher Fort from 20 January to 18 May 1754. The war continued for about four months. During the war Khanderao Holkar, son of Malhar Rao Holkar, was one day inspecting his army in an open palanquin, when he was fired upon from the fort. The cannonball hit and killed him on 24 March 1754. Malhar Rao was infuriated by the death of his only son and wanted to take revenge. He vowed that he would cut off the head of Maharaja Suraj Mal and throw the soil of fort into Yamuna after destroying it. The Marathas increased pressure and Suraj Mal defended pacifly, but Suraj Mal was isolated as no other ruler was ready to help him. At this moment, Maharaja Suraj Mal was counseled by Maharani Kishori, who assured him not to worry and started diplomatic efforts. She contacted Diwan Roop Ram Katara. She knew that there were differences between Malharrao Holkar and Jayappa Sindhia and that Jayappa Sindhia was very firm in his determinations. She advised Maharaja Suraj Mal to take advantage of mutual differences within Marathas. Diwan Roop Ram Katara was a friend of Jayappa Sindhia. She requested Diwan Roop Ram Katara to take a letter from Maharaja Suraj Mal proposing a treaty. Jayappa Sindhia assured Suraj Mal of assistance and contacted Raghunathrao. Raghunathrao in turn advised Holkar to sign a treaty with Suraj Mal. Malhar Rao Holkar assessed the situation and consented for the treaty due to possibility of isolation. This led to a treaty between both rulers on 18 May 1754. This treaty proved very beneficial for Maharaja Suraj Mal.
