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.
Bhavabhushan Mitra
In April 1908, Bhavabhushan accompanied Bagha Jatin and his family to Darjeeling. Jatin had founded there active branches of the Kolkata Anushilan Samiti. Bhavabhushan has left a first-hand account of the way, at the Siliguri railway station, Jatin taught a substantial lesson to four conceited British army officers : the legal proceedings drawn up against Jatin had turned into such a sensation in the written press that the officers withdrew their complaint.
