GHAUS KHĀN (d. 1814) was an artillery officer under Mahāṅ Siṅgh Sukkarchakkīā, and after his death, under his son, Raṇjīt Siṅgh. He knew something about casting guns, was skilful in his profession, and was rewarded with jāgīrs at Vāṅ and Bharovāl in Amritsar district, with a large house in Lahore which was later occupied by the Mission School. When, in 1812, the Mahārājā reorganized the artillery wing of his army into Topkhānā -i-Khās and Topkhānā -i-Mubārak, Ghaus Khān was put in charge of both, with the designation of Daroghā-i-Topkhanā. Ghaus Khān distinguished himself in several of the Mahārājā's early campaigns. In 1807, he reduced the fortress of Sheikhūpurā and secured the surrender of its defiant chiefs, Arbel Siṅgh and Amīr Siṅgh. In 1810, he captured Paṭṭī and the villages in the vicinity of Tarn Tāran. In 1813, he was put in charge of operations against Attock whose Afghān governor, Jahāṅ Dād Khān, eventually surrendered. Ghaus Khān commanded the Sikh artillery under Dīwān Mohkam Chand in the severely contested battle of Haidrū (13 July 1813) in which the Sikhs routed the Afghān forces of the Kābul Wazīr, Fateh Khān. In 1814, Ghaus Khān took part in Mahārājā Raṇjīt Siṅgh's expedition against Kashmīr. The Sikh army under the Mahārājā reached Puñchh but rain and sickness caused havoc. Cholera broke out and Ghaus Khān fell a prey to the epidemic and died on his way to Lahore.
