Gurdwara Sri Nirmohgarh Sahib is situated on top of a low hill about 4 km south of Kiratpur.
In August 1700, Anandpur, which was the seat of Sri Guru Gobind Singh Ji, was attacked by a combined force of several of the surrounding hindu hill chiefs.
For four days, the hindu troops assaulted the four Sikh fortresses built around the main citadel, Anandgarh. The hindu found the fortresses could not be overcome.
Finally, they laid a siege to Anandgarh in the hope of starving the Sikhs into surrender, but without effect. They then resorted to a typical brahman ruse.
The hindu hill chiefs offered peace to Guru Gobind Singh upon solemn oaths, if only he would leave Anandpur temporarily to enable them to lift the siege with honour.
Guru Gobind Singh agreed and on 2nd October 1700 retired to a camp set up on the hills around the village of Hardo Namoh.
The hill top where Guru Gobind Singh had established himself came to be known as Namohgarh or Nirmohgarh. The hill rajas did not keep their word, and again surrounded the Sikhs. The Sikhs repulsed the hindu attacks which, according to the Bhatt Vahis, took place on 7th, 12th, and 13th October 1700.
On 14th October Guru Gobind Singh and his Sikhs broke the cordon and crossed the Sutlej into Basohli, a small friendly state. It is said that, during the siege of Nirmohgarh, the hill chiefs succeeded in requisitioning the services of some imperial mughal troops, including a cannoneer.
Just at the opening of the next engagement, the cannoneer fired a shot aimed at Guru Gobind Singh, who was sitting on the top of Nirmohgarh hill. The Guru, however, remained unhurt, although an attendant, Bhai Ram Singh, was killed. The Guru instantly picked his bow and arrow and pierced the cannoneer dead. The site now has a memorial in the shape of small single room Gurdwara. The Gurdwara is managed by Nihangs.
