The Gorkha force under the command of Khajanchi Bir Bhadra Upadhyay and Sardar Banshu Gurung defeated the British troop in November 1767 (Kartik 24, 1824 BS).

In connection to the unification of Nepal King Prithivi Narayan Shah surrounded the Kathmandu Valley and made an economic blockade.

In August 1767, when the forces of British India arrived in Sindhuli Gadhi, the Gorkha military conducted a guerrilla attack against them.

Many of the British Indian forces were killed and the rest eventually fled, leaving behind a huge amount of weapons and ammunition, which were seized by the Gorkha army.

Gorkha army under Banshu Gurung's command had prevented the British troops from advancing towards the Kathmandu Valley.
