[4] In 1739, Nara Bhupal Shah signed a peace treaty with Lamjung which made the east flank safe with plans to capture Nuwakot.

[3] After the treaty, Maheswor Pant and Kaji Jayant Rana Magar of Gorkha were commanded to attack Nuwakot, however, they were defeated.

[5] Nobles, and Bhardars who supported Maheswor Pant criticised that Biraj Thapa Magar was a coward for spending a long time to attack.

[6] Shah hired some people to drill and practice his soldiers and with the help of craftsman he availed himself to make gunpowder, arrows, shafts, Khundas (sword), and Khukuris.

[7] Shah began to set up friendly relations with neighbouring kingdoms due to the danger to Gorkha if he attacked Kantipur.

[7] He also sent messengers to ask for assistance in his attempt to capture Nuwakot, Chaubisi Rajyas and others rejected to provide military aid but Kingdom of Lamjung established a friendship with Gorkha.

[9][10] Prithivi Narayan Shah assigned a Jaisi Brahmin, Kalu Adhikari, to perform a Tantric ritual which included burying a nail to opponent's soil believing that they could win the battle.

[11] At the same time, Prithivi Narayan Shah was trying to find where to launch an attack, not to repeat the past mistake, by crossing Trishuli River Bridge.

[11] Day before, Shah commanded Kaji Kalu Pande to be ready for a strike, the Gorkhas, got together with their weapons, and the king split the army into three groups.

[12] Three groups met at Shubha Ghat, Jaluwa Manjhi, transported them across the Trishuli River, the force also included the brother of the king Dal Mardan Shah, royal preceptor, priest and astrologers, who were given weapons.

[13] The defenders started to run away without fighting back as they were unprepared, seeing this, Shankha Mani Rana Magar,[14] motivated them to attack but they did not listen.

[13][15] Remarkably, wounded Sankha Mani Rana Magar charged the Gorkhali soldiers with a sword then they surrounded him, and he challenged Dal Mardan Shah.

[15] Prithivi Narayan Shah's group received a message saying that Mahamandal was captured thus the king went to attack the fort, Nuwakot Gadhi.

[15] The fort defenders could not resist the attack by the Gorkhali in the darkness and rather than fighting they fleed to Belkot as well since they already received the news about the death of their commander Sankha Mani Rana Magar.

[17] Few days later, in the Battle of Belkot, Jayanta Rana Magar was captured, imprisoned, and was skinned alive with people from Nuwakot, and Gorkha spectating his death.
