After some time his elder brother Sadhu Singh died, and as he came on leave to attend the obsequies, he, under pressure from his family and oilier relatives, married his brother`s widow, Btbt Harnam Kaur, by the custom of chddar anddd, i.e. by tying the conjugal knot.In 1915 he resigned from the army and returned to his village. As the Gurdwara Reform movement got under way, he registered his name as a volunteer with a jalhd of BhaT Lachhman Singh. And when the final call came on 19 February 1921, he along with some others from his village marched to Nankana Sahib, and fell a martyr outside the walled compound of Gurdwara Janam Asihan, the following morning. Bhat Karam Singh was survived by his mother, wife and four minor children. The Shiromant Gurdwara Parbandhak Committee settled upon the family a pension of Rs 240 per annum and discharged the small debt it had incurred. See NANKANA SAHIB MASSACRE
