Rash Behari concluded that the British rulers would not yield without revolutionary action on the part of the patriots. He started gearing up his revolutionary activities under the guidance of Jatin Banerjee, an eminent revolutionary leader.
Rash Behari Bose suddenly came in to prominence after 23rd December 1912 when bombs were thrown at Lord Hardinge, the then Viceroy of India.
The planning for it was ingenious. At a conclave in Chandan Nagar, the suggestion for an attack on Lord Hardinge emanated from Shreesh Ghosh, a daredevil friend of Rash Behari.
