The Canadian authorities reported to the Indian government his revolutionary activities and charged him with the murder in Vancouver of Harnam Singh, a loyalist. In the Punjab, Jagat Singh became a close associate of Ghadr leaders, such as Kartar Singh Sarabha. He took part in the Chabba, Sahncval, and Mansurari dacoitics, looted money which was turned over to the revolutionary centre, and offered to sell his land for the cause. He also helped in the manufacture of bombs. He escaped arrest when the revolution was betrayed by a police spy, Kirpal Singh.
In company with Kartar Singh Sarabha and Harnam Singh Tundilat, Jagat Singh made his way to Kabul. They returned to the Punjab, determined to seize arms and free their imprisoned comrades. They were arrested, however, at Sargodha, where they were attempting to seduce the soldiers of the 22nd Cavalry to which Jagat Singh had once belonged. Tried in the first Lahore conspiracy case, Jagat Singh was sentenced to death. He was hanged on 16 November 1915 along with Kartar Singh Sarabha.
