Victory over Makwanpur

Makwanpur was supplying goods necessary to fulfill daily needs to the Kathmandu Valley because Makwanpur was against Gorkha. Makwanpur wanted to side with the three kingdoms of Kathmandu Valley i.e. Kantipur, Bhadgaon and Patan). So, Prithvi Narayan Shah thought it crucial to conquer Makwanpur and tighten the economic blockade on the valley. Further, there was misunderstanding and cold relations between the Gorkhali King and Digbandan Sen, the King of Makwanpur. Prithvi Narayan Shah wanted revenge too. Makwanpur had fertile land and a suitable climate for agriculture. It was also a trade route to the south. Thus, Makwanpur was in every sense the most strategic state to be occupied by the Gorkhali forces. On 1762 A.D., the Gorkhali force invaded Makwanpur and occupied it without  much effort. Digbandan Sen fled to India and sought refuge from the Nawab of Bengal, Mir Kasim. Digbandan Sen asked Mir Kasim for military help in order to rescue Makwanpur from the Gorkhalis. Mir Kasim sent 2500 to 3000 soldiers to Makwanpur under the command of Gurgin Khan. On 1763 A.D the Gorkhali soldiers surrounded the forces of Gurgin Khan. The Muslim forces could not resist against the guerrilla warfare of the Gorkahlis. Thereafter, the Gorkhalis occupied Bara, Parsa, Sarlahi and Mahottari of the Terai. Similarly, Dhulikhel, Panauti, Nala, Banepa etc. all of which surrounded the Kathmandu Valley, were strategically controlled. This made it possible to tighten the economic blockade on the Kathmandu Valley.
