Sukhdev was a member of the Hindustan Socialist Republican Association, and organised revolutionary cells in Punjab and other areas of North India. He was the chief of Punjab unit of HSRA and instrumental in taking decisions. Sukhdev participated in numerous revolutionary activities such as a prison hunger strike in 1929; he is best known for his assaults in the Lahore Conspiracy Case.. He is best remembered for his involvement in the assassination of Deputy Superintendent of Police, J. P. Saunders, on 18 December 1928, by Bhagat Singh and Shivaram Rajguru, undertaken in response to the violent death of the veteran leader Lala Lajpat Rai.
Sukhdev was the prime accused in the Lahore Conspiracy Case of 1930, whose official title was "Crown versus Sukhdev and others." The first information report of the case, filed by Hamilton Harding, senior superintendent of police, in the court of R.S. Pandit, the special magistrate in April 1929, mentions Sukhdev as accused number 1. It describes him as Swami alias villager, son of Ram Lal, caste Thapar Khatri. After the Central Assembly Hall bombings in New Delhi, Sukhdev and his accomplices were arrested, convicted, and sentenced to death.
Execution
On 23 March 1931, Thapar was hanged in Lahore jail, along with Bhagat Singh and Shivaram Rajguru. Their bodies were secretly cremated at the banks of the River Sutlej.
Reactions to the executions
The executions were widely reported in the press, especially as they took place on the eve of the annual convention of the Indian National Congress in Karachi. The New York Times reported: B. R. Ambedkar, writing in an editorial in his newspaper Janata, blamed the British government for its decision to go ahead with the executions, despite strong popular support for the revolutionaries. He felt that the decision to execute the trio was not taken in the true spirit of justice, but was driven by the Labour Party-led British government's fear of backlash from the Conservative Party and a need to appease public opinion in England. The Gandhi-Irwin pact, signed just weeks before the execution, was viewed by the Conservatives as having dented the prestige of the British Empire. In such a situation, if the British government or the Viceroy of India commuted the death sentence awarded to the trio convicted of assassinating a British policeman, it would have given the Conservatives more ammunition to criticize an already weak British government in the parliament.
