[1][2] Prithvinarayana, the ruler of Gorkha, aimed to economically isolate the Kathmandu Valley.

Additionally, he conquered strategic locations such as Makwanpur, Timalkot, Sindhuli, and Hariharpur on the Mahabharat range southwest of the valley, effectively blocking the southern routes to India.

Firstly, Ali Mir Kasim, the Nawab of Bengal, was incited by Digbandhan Sena, the displaced ruler of Makwanpur and Prithvinarayana's first wife's brother, to attack the Gorkha stronghold in Makwanpur.

In response, Prithvinarayana engaged Mir Kasim's general, Gurgin Khan, at Makwanpur, where he decisively defeated the advancing troops and forced them to retreat.

[3][4][5] This event underscored Prithvinarayana's military prowess and determination to maintain control over strategic territories, thereby securing his position and objectives in the region.
