Peter Stark Lumsden was born at Belhelvie Lodge, Belhelvie, Aberdeenshire, on 9 November 1829. He was trained at Addiscombe Military Seminary from the age of 20, and entered the East India Company'sBengal Army in 1847 as an ensign in the 60th Bengal Native Infantry. Between 1852 and 1857 he served on the North-West Frontier in five expeditions against native tribes: the Mohmunds, the Ootman Khel, the Bori Afridis and the Miranzais. He was mentioned in despatches five times and awarded the special thanks of the Local and supreme Governments. From 1857 to 1858 he accompanied a special peace-finding mission to Kandahar with his brother Harry Lumsden. He received thanks from the Government for his work, but returned to India to take part in the suppression of the Indian Mutiny. Lumsden next joined the Central India Field Force at Gwalior under General Sir Robert Napier, and, as assistant quartermaster general under Major-General Hugh Rose, shared in the pursuit and capture of Tantya Tope in 1859, when he was again mentioned in despatches.
Lumsden's next period of active service was as quartermaster general on the staff of General Napier, who commanded the 2nd division of the expeditionary force to China during the Second Opium War, in 1860. Lumsden took part in the operations of the Anglo-French forces, including the action of Sin-ho, the capture of Tang-ku and the capture of the Taku Forts that led up to the advance on and occupation of Beijing. He was again mentioned in despatches and promoted to brevet-Major and then brevet-lieutenant-colonel. The final spell of active service in Lumsden's military career was in the Bhutan War of 1865: his later employment was on the staff and in political posts. He was deputy quartermaster general from 1864 to 1868, and quartermaster general of the Indian Army from 1868 to 1873. He was Acting Resident in Hyderabad, 1873, and Adjutant-General, India from 1874 to 1879, when he was appointed Chief of the Staff in India. He also served for eleven years as an aide-de-camp to Queen Victoria.
Lumsden served as Chief of Staff to the commander-in-chief, General Sir F. P. Haines, during the Second Anglo-Afghan War, for which he received the Order of the Bath. In 1884, Lumsden returned to the North-West frontier, when he was selected as British representative on the Anglo-Russian Commission for the demarcation of the north-west boundary of Afghanistan, but resigned and returned to England in 1885 after the Panjdeh Incident. He left London to represent the British at negotiations with Russia in selecting the Afghan Frontier Commission to determine the Afghan boundary. Lumsden was appointed a Knight Grand Cross of the Order of the Bath and given a commissioner's seat on the Council of India, which he occupied for a 10-year tenure from 1883. In 1885 he wrote "Countries and Tribes Bordering on the Koh-i-Baba Range", an article for the seventh volume of the journal Proceedings of the Royal Geographical Society and Monthly Record of Geography.
Later life
Following completion of his tenure on the Council of India, Lumsden retired from military service in 1893. He was placed on the Unemployed Supernumerary List three years later and settled down on Buchromb, an estate that he had purchased near Dufftown. During this time he co-wrote Lumsden of the Guides with G. R. Elsmie. The book detailed the role that his brother, Harry Burnett Lumsden, had played in founding The Corps of the Guides, a regiment of the British Indian Army. He identified himself with local affairs and served as a justice of the peace and as Deputy Lieutenant for Banffshire and Aberdeenshire. Lumsden died on 9 November 1918 in his estate at Dufftown, Banffshire.
Family
Lumsden was married to Mary Marriott in 1862. His father was Colonel Thomas Lumsden CB, with one of his three older brothers being Harry Burnett Lumsden. Thomas Lumsden was a distinguished officer of the Bengal Horse Artillery who had served in the Nepal Campaign of 1814 and at the Siege of Hatrass and the capture of Kalunga in 1817. Thomas was himself the son of Harry Lumsden, an advocate in Aberdeen who had bought an estate at Belhelvie. He returned home on leave from the Bengal Army in 1819 to marry Hay Burnett of Elrick, and went on to serve another 23 years in India before retiring to Belhelvie in 1842. They had a total of six sons, of whom three emigrated to Canada and two followed in their father's footsteps by pursuing military careers in India.
