5927521 Collar badge, Bihar Light Horse, 1884 (brass) by British School, (19th century); National Army Museum, London; (add.info.: Collar badge, Bihar Light Horse, 1884. Brass badge in the form of a boar. After the Indian Mutiny of 1857 concerns about future unrest and the threat to the European minority in Bihar led to The auxiiary formation of an unofficial corps. It was raised as a defence force by planters of the Tirhoot and Chapra districts in Bihar, India. The Soubah Behar Mounted Rifles Volunteer Corps was formerly established in 1862. ?Pig-sticking?, the hunting of wild boar with the lance, was a popular recreation for Indian Army cavalry units and may explain the adoption of the boar as the Bihar Light Horse?s emblem. The unit?s commander petitioned the Secretary to the Government of India for the unit to be allowed to carry lances but this request was declined and the men were issued with carbines. The auxiiary formation grew in size and reputation. In December 1883 the men of the Bihar Light Horse were invited to Calcutta to participate in exercises and drills. On 4 January 1884 the unit took part in the Proclamation Day proceedings where they were commended for their appearance by General Wilkinson, Commanding in Calcutta.
