Bhai Kahan Singh was the son of Bhai Binod Singh. He was direct in line of Guru Angad Sahib. Both Bhai Binod Singh and Bhai Kahan Singh joined Guru Gobind Sahib on his way from Talwandi Sabo to Nander. Both father and son were among the five Sikhs who accompanied Baba Banda Singh Bahadur from Nander to the Punjab, on October 5, 1708. From 1709 to 1714, he participated in several battles. In 1710, he was appointed deputy chief (his father being the chief) of Karnal. In October 1710, he fought against the Mogul army at Taravari, Kurukashetra and Shahbad. During the siege of Gurdas Nangal, he parted with Baba Banda Singh and formed a separate Jatha, later came to be known as the Tat Khalsa. Baba Banda Singh was captured at Gurdas Nangal and was taken to Delhi as a prisoner. Later, Kahan Singh too was arrested. He too was taken to Delhi and was executed there in March 1716.
