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.
Pulin Behari Das
In September, 1906, Bipin Chandra Pal and Pramatha Nath Mitra took a tour of the newly created province of Eastern Bengal and Assam. The latter, while delivering his speech, asked them to come forward who were willing to sacrifice their lives for their country and Pulin had stepped forward. Subsequently, he was nominated to organize the Dhaka chapter of the Anushilan Samiti. In October, Pulin founded the Dhaka chapter with 80 young men.
