The Gurudwara Dukh Niwaran Sahib is the site where Guru Tegh Bahadur Ji healed a sick person. At the time of Akali Baba Hanuman Singh Ji, the next leader of the Akal Takht Sahib and Khalsa Army (Dal Panth - Buddha/Tarana Dal), there was no large Gurughar as we see today.
Akali Phoola Singh had attacked Metcalfe previously, and others. Nihang Singh oral tradition states that the East India company sent spies to Anandpur Sahib, in the guise of Priests, to collect information. Akali Phoola Singh became aware, and knew the British planned an attack. He outsmarted the English gentlemen who were very clever and cunning in their strategy. Akali Phoola Singh put siege to a whole regiment of the British Army. All of the men were killed apart from the General, who was told to go back to his leaders and tell them never to set foot into the Punjab. Of course they did as they were invited by Ranjit Singh. Anyhow the British obviously had it in for the Nihang Singh Khalsa after that day.
When Akali Phoola Singh was Shahid, the British and treacherous Sikhs knew it was their time to extract revenge on the Buddha Dal. Akali Baba Hanuman Singh was the new leader, the British attacked his army in the Patiala all the way upto Chandigarh area. He was wounded, and many Singhs, at least 15, 000 were Shahid. There is a Gurdwara and plaque at Sohana (Chandigarh):
Members of the respected Guru's presence, this is the martyrdom place where the Seventh Jathedar, the great great Martyr General Saint Hanuman Singh, the leader of the Akal Takht, was marytred. His fathers name was Garja Singh and his mothers name was Harnam Kaur. He was born in 1755 in Narangpur. He served the Buddha Dal for ten years.
In 1845 the treacherous Gulab Singh Dogra, Tej Singh and the British joined forces to end the true Sikh Kingdom. At that time Maharani Jind Kaur had sent a letter with Sham Singh Attari, to ask the Seventh leader of Buddha Dal (Baba Hanuman Singh) at the Akal Takht in Amritsar, for help. The Leader with the Singhs went to battle.

The Gurdwara Dukh Niwaran Sahib, is a place of great sadness for the Panth, where the Kings of Punjab sold out Sikhi, for their British masters. The Gurdwara was built as a memorial to the Singhs who were killed in cold blood, but today the real history of the site has been suppressed. It is sad that the same Kings sell out Sikhi for the GOI, even today.
