Badhan Singh, an emigrant martyr of the Ghadar Party, was born in the home of Baghel Singh in the village Dalel Singh Wala in Mansa district (then Patiala) of Punjab in about 1864. Jeoni, was the name of her mother. He joined the British Indian Army and spent the majority of his time in Burma (Myanmar). He resigned and returned home after five years of service. He did agriculture in his village for the next ten years.
He moved to Hong Kong in 1902 and worked as a jail guard. He relocated to Canada in 1907. There, he worked in a lumber mill in New Westminster, Vancouver. In November 1908, he became a partner in Sant Teja Singh's Guru Nanak Mining and Trust Company. He comes across white prejudice, anti-Asian feelings, and threats of exclusion and deportation of Indian immigrants. Such happenings influenced his political views. He became involved in nationalistic activities and spoke out against British rule. A devout Sikh, he also actively participated in community welfare activities and made the Vancouver gurdwara his permanent home.
Badhan Singh was present when British Intelligence officer William Hopkinson's agent Bela Singh shot at Bhag Singh in the Vancouver gurdwara. He tried to stop him but he was shot four times in the upper body during the altercation. Eight people were injured as a result of Bela Singh's indiscriminate shooting. He is Hopkinson's chief informant, earning $62.50 per month from the government. Badhan Singh was seriously injured, and his vital organs stopped functioning. This proved fatal, and he succumbed to bullet injuries on September 6, 1914. At that time, he was 50 years old.
During Bela Singh's court appearance, police concocted a story. Bela Singh's friends claimed he fired in self-defense as in the presence of Guru Granth Sahib, Bhag Singh and Bela Singh argued, and Badhan Singh arrived, saying he would fix Bela Singh and pulled a black pistol from his pocket. Badhan Singh fired on Bela Singh but it was later revealed that it was nothing more than a fabricated account of the events that occurred that day in the gurdwara. The court ordered Bela Singh's release. When Bela Singh returned to Punjab, Babbars avenged Badhan Singh's murder by killing him.
