Both the British and the Gorkha armies had become accustomed to previous enemies who broke and ran when faced with organized military opposition. Here, both faced an enemy which stood and fought bravely. Both sides treated prisoners honourably. By the end of the war a mutual respect had grown up between the British and the Gurkhas, and the Gorkha Army’s suggestion that they would prefer to fight on the side of the British rather than against them was swiftly accepted. On 24th April 1815, the first three Gorkha regiments were formed. They were named the 1st (Nasiri Battalion), the 2nd (Sirmoor Battalion) and the 3rd (Kumaon Battalion). The battalions consisted of eight companies adn each company had 120 men . Lieutenant Frederick Young was the first British Officer who raised the Sirmoor Battalion from Gurkha prisoners of war. When General Ochterlony finally defeated General Amarsing Thapa, a treaty was signed at Sagauli on 4 March 1816 where it was agreed that Nepal would give up the provinces of Kumaon and Garwal in the west that they won as well as the Terai lowlands.
