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.

Following the arrest of Pulin Behari Das ( the main organizer of the Dhaka branch of Anushilan Samiti), Pratul and Trailokyanath Chakravarty took charge of the Anushilan Samiti and reorganized the association. He was tried in the Barisal conspiracy case and was sentenced for 10 years imprisonment in 1914, however he was released earlier. In 1922, he joined Congress.
