"The Sirmoor Battalion (later to become 2nd King Edward VII's Own Gurkha Rifles) was the first Gurkha regiment to be formed by the British East India Company. Sirmoor Battalion took part in the 3rd Maratha War in between 1817-1818. The British eventually triumphed, and the once mighty Maratha Empire was absorbed into 'British India', leaving Britain in control of virtually all of present-day India."-
