[citation needed] He was a Minister of State in 1800 A.D. and the Governor of Kumaun from 1814 to 1815 A.D. at Anglo-Nepalese war.
British force numbering initially over 4500 men was easily able to out maneuver Nepalese Army defenders and had to abandon one post after another.
Despite significant victory over Captain Hearsey's force which had been sent in flanking movement through Eastern Kumaun and the capture of captain himself, Bam Shah's Nepalese force couldn't stern the tide of British advance.
Meanwhile, Lord Hastings sent Colonel Nicolls, Quartermaster-General for all British force in India, to take charge of Almoda campaign and assigned 2000 army men with large irregulars against 1000 Nepalese.
He then sent letter to Bada Kaji Amar Singh Thapa who was Supreme Commander of Western Front, about the fall of Almora.
