In connection to the unification of Nepal King
Prithivi Narayan Shah surrounded the
Kathmandu Valley and made an economic blockade. The king of Kathmandu at the time,
Jaya Prakash Malla, then wrote a letter to the British military in India, requesting for military assistance. 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. Gorkhas had used unconventional war tactics like unleashing the hornets and using nettles, among a variety of other tactics, to defeat the British soldiers. ==Historical Commemoration==
