History of the Anushilan Samiti
Around 1902, Aurobindo Ghosh arranged for Bannerjee to return to Calcutta to begin organisational work, where he began a gymnasium and a youth society. It was at this time that Bannerjee came in touch with Vibhuti Bhushan Bhattacharya, Sarala Devi Ghoshal and Pramathanath Mitra. In Calcutta, a few clubs and societies were still active at the time. Most notable was a gymnasium in Ballygunge Circular Road run by Sarala Devi herself, a second was an organisation named "Anushilan Samiti" founded by Satish Chandra Basu with the patronage of Pramathanath Mitra. A third one was a youth club called "Attōnnōti Samiti" (Self-improvement society) in central Calcutta.

Meanwhile, in 1912, Jatin met in the company of Naren Bhattacharya the Crown Prince of Germany during the latter's visit to Calcutta in 1912, and obtained an assurance that arms and ammunition would be supplied to them. Jatin was intimated of Rash Behari's work through Niralamba Swami while on a pilgrimage to the holy Hindu city of Brindavan. Returning to Bengal, Jatin began reorganising his group. Rash Behari had gone into hiding in Benares after the 1912 attempt on Hardinge, but he met Jatin towards the end of 1913, outlining the prospects of a pan-Indian revolution.
