NIDHAN SINGH, a Varaich Jatt of Patti in present day Amritsar district of the Punjab, was, according to Sarup Singh Kaushish, Guru kian Sakhian, the husband of the celebrated Sikh heroine, Mai Bhago. He was one of the warriors who fell fighting in the battle of Muktsar fought on 29 December 1705 and who were blessed by Guru Gobind Singh as mukte, the Liberated Ones. NIDHAN SINGH (d. 1850) or Nidhan Singh Hathu, i.e. Nidhan Singh the Inflexible, son of Jassa Singh, was a bold warrior in Sikh times who, inheriting Daska in Sialkot district from his father, had acquired considerable territory.
NIRMOHGARH SAHIB, GURDWARA, situated on top of a low hill 4 km south of Kiratpur (31° ll`N, 76° 35`E), is dedicated to Guru Gobind Singh. In August 1700, Anandpur, which was then the seat of Guru Gobind Singh, was attacked by a combined force of several of the surrounding hill chiefs. For four days, their troops assaulted successively the four fortresses built around the main citadel, Anandgarh, but they found all of them impregnable. Finally, they laid a siege to Anandgarh in the hope of starving the Sikhs into surrender, but without effect. They then resorted to a ruse.
