Members of the Jugantar faction of the Bengali revolutionary organisation Anushilan Samiti intercepted a shipment of Mauser Pistols and ammunition belonging to Messrs Rodda & co., a Calcutta gun dealer, while these were en route from the Customs house to the company's godown, and were able to make away with a portion the arms.
Western Anushilan Samiti in the aftermath of Manicktala Conspiracy found more prominent leader in Jatindra Nath Mukherjee which emerged distinctly as the Jugantar group.
He revitalised the links between the central organisation in Calcutta and its several branches spread all over Bengal, Bihar, Orissa and several places in U.P., and opened hideouts in the Sundarbans for members who had gone underground[citation needed] The group slowly reorganised guided by Mukherjee's efforts, aided by an emerging leadership which included Amarendra Chatterjee, Naren Bhattacharya and other younger leaders.
[4] In 1912, Jatin met in the company of Naren Bhattacharya the Crown Prince of Germany during the latter's visit to Calcutta, and obtained an assurance that arms and ammunition would be supplied to them.
Informed of the impending arrival, a group of Jugantar members headed by Anukul Mukherjee met on 24 August 1914 in Bowbazar suburb of Calcutta.
Haridas Dutta was arrested in September 1914, and served prison sentences for his role in the heist, along with Kalidas Basu, Bhujanga Dhar and Girindranath Banerjee.
In the following years, these arms were linked to the majority of revolutionary crimes in Calcutta and Bengal till 1917, including Bagha Jatin during his last stand at the banks of Budhabalanga River.
Mukherjee, the planner of the heist, along with Bannerjee, Dutta, and Bipin Bihary Ganguly are commemorated in Calcutta today, with a memorial and their statues of their busts erected in Ganesh Chandra Avenue.
