About 5,000 men entered British service in 1815, most of whom were not just Gorkhalis, but Kumaonis, Garhwalis and other Himalayan hill men. These groups, eventually lumped together under the term Gurkha, became the backbone of British Indian forces.
As well as Ochterlony's Gurkha battalions, Fraser and Lt. Frederick Young raised the Sirmoor Battalion, later to become the 2nd King Edward VII's Own Gurkha Rifles. An additional battalion—the Kumaon—was also raised, eventually becoming the 3rd Queen Alexandra's Own Gurkha Rifles. None of these units fought in the second campaign.
Gurkhas served as troops under contract to the British East India Company in the Pindaree War of 1817, in Bharatpur in 1826, and the First and Second Anglo-Sikh Wars in 1846 and 1848.[7]
During the Indian Rebellion of 1857, Gurkhas fought on the British side and became part of the British Indian Army on its formation. The 8th (Sirmoor) Local Battalion made a notable contribution during the conflict, and 25 Indian Order of Merit awards were made to men from that regiment during the Siege of Delhi.[13]
Three days after the rebellion began, the Sirmoor Battalion was ordered to move to Meerut, where the British garrison was barely holding on, and in doing so they had to march up to 48 kilometres a day.[14] Later, during the four-month Siege of Delhi, they defended Hindu Rao's house, losing 327 of 490 men. During this action they fought side by side with the 60th Rifles and a strong bond developed.[15][16]
Twelve regiments from the Nepalese Army also took part in the relief of Lucknow[17] under the command of Shri Teen (3) Maharaja Jung Bahadur Rana of Nepal and his older brother C-in-C Ranodip Singh Kunwar (Ranaudip Singh Bahadur Rana) (later to succeed Jung Bahadur and become Sri Teen Maharaja Ranodip Singh of Nepal).
After the rebellion the 60th Rifles pressed for the Sirmoor Battalion to become a rifle regiment. This honour was granted in 1858 when the battalion was renamed the Sirmoor Rifle Regiment and awarded a third colour.[18] In 1863, Queen Victoria presented the regiment with the Queen's Truncheon, as a replacement for the colours that rifle regiments do not usually have.[19]
