In another action the raja of Hindur, Bhup Chand, was seriously wounded by a shot from his musket following which the entire hill army fled the field. Sahib Chand was one of the five Sikhs who, on the Baisakhi day of 30 March 1699, offered, upon Guru Gobind Singh`s call, to lay down their heads. They were greeted by the Guru as the five beloved of him. These five formed the nucleus of the Khalsa, the Guru`s own, inaugurated dramatically on that day. Sahib Chand, after undergoing the rites of the Khalsa, became Sahib Singh, receiving the surname of Singh common to all members of the Khalsa brotherhood. Bhai Sahib Singh fell in the battle of Chamkaur on 7 December 1705.
