The Delhi Conspiracy case, also known as the Delhi-Lahore Conspiracy, refers to an attempt made in 1912 to assassinate the then Viceroy of India, Lord Hardinge by throwing a local self-made bomb of Anushilan Samiti by Basanta Kumar Biswas, on the occasion of transferring the capital of British India from Calcutta to New Delhi.
[1] Hatched by the Indian revolutionaries underground in Bengal and Punjab and headed by Rash Behari Bose, the conspiracy culminated in the attempted assassination on 23 December 1912, when a homemade bomb was thrown into the Viceroy's howdah as the ceremonial procession was moving through the Chandni Chowk suburb of Delhi.
Rash Behari Bose, identified as the person who threw the bomb, successfully evaded capture for nearly three years, becoming involved in the Ghadar Conspiracy before it was uncovered, then fleeing to Japan in 1915.
The case was filed against Lala Hanumant Sahai, Basanta Kumar Biswas, Bhai Balmukund, Amir Chand and Awadh Behari.
Basanta Kumar Biswas was hanged on 11 May 1915 at Ambala Central Jail in Punjab aged twenty and became one of the youngest people to be executed during the Indian revolutionary struggles during the 20th century.
