According to Nixon's Report, probably in about 1913, or perhaps a little before, certain of the old members of the Kolkata Anushilan Samiti who, in the meantime, had been members of various athletic clubs, formed themselves into a branch of the
Seva Samiti under Atulkrishna Ghosh: "The ostensible object of this
samiti was a benevolent one. The first centre was at the house of Atul Ghosh. During the
Burdwan floods, in 1913, many members of this
samiti went there for the purpose of affording relief to the afflicted people.". Atul's efficiency and generosity as a leader became evident during this relief. Nixon further informs that the headquarters of the samiti were later shifted to the house of
Jibantara Haldar, and later still to No. 83 Hari Ghosh's Street. "Of this organisation Amar Ghosh, the brother of Atul, was an important figure," mentioned Nixon. "It was this
samiti which formed the nucleus of the combined party which operated in Bengal in 1915.
Purna Das of
Madaripur brought some of his more audacious spirits along to it and later
Pulin Mukherji alias Thakur, previously a member of the Dacca Anushilan Samiti, joined it and took a prominent part in the commission of outrages. Other members of the Dacca Anushilan Samiti severed their connection with that society and joined the party of Atul Ghosh.
Bipin Behari Ganguli was in close connection with it and also the members of the Northern Bengal party.
Jatindranath Mukherjee seems to have been in touch with the members of this
samiti from the time of its formation, and immediately he came into Calcutta, the Seva Samiti acknowledged his leadership and became the real West Bengal party of 1915.". During the
Alipore Bomb prosecutions, though
Rasbehari Bose had settled in North India with the help of
Shashibhushan Raychaudhury, he maintained his contact with Bengal through Atul.
Amarendra Chatterjee and Atul supplied him bombs for actions in up-country and, even, the one thrown on Viceroy Hardinge. Informed by Atul, Rasbehari could participate in the flood relief and the significant meetings of leaders. It was Atul, again, in September 1914, who was contacted by
Gurudit Singh and other
Komagata Maru patriots, coming from Vancouver with recommendation from
Taraknath Das : he and
Satish Chakravarti arranged with various regional units of the
Jugantar to shelter them, before sending them to destinations in North India, fixed by Rasbehari. Furious to hear about the death of a jute-mill worker at Jagaddal, caused by the kick from a booted leg of an English supervisor, Atul was desperately looking for arms to avenge this atrocity. ==In need of arms==
