Anushilan Samiti
Anushilan and Jugantar each were organised on different lines, reflecting their divergence. "Anushilan Samiti" was centrally organised, with a rigid discipline and vertical hierarchy. Jugantar, was more loosely organised as an alliance of groups, acting under local leaders that occasionally coordinated their actions together. The prototype of Jugantar's organisation was Barin Ghosh's organisation set up in 1907, in the run-up to the Manicktolla conspiracy. It sought to emulate the model of Russian revolutionaries that was described by Frost. The regulations of the central Dhaka organization of the "Anushilan Samiti" were written down, and reproduced and summarised in government reports. According to one estimate, the Dacca Anushilan Samiti had at one point 500 branches, mostly in the eastern districts of Bengal, with 20,000 members. Branches were opened later in the western districts, Bihar, and the United Provinces. Shelters for absconders were established in Assam and in two farms in Tripura. Organisational documents shows a primary division between, on the one hand the two active leadersBarin Ghosh and Upendranath Bannerjee, and the rank-and-file on the other. Higher leaders including Aurobindo were supposed to be known only to the active leaders. Erstwhile members of "Anushilan", particularly those of the Maniktala group, had suggested that the each group were interconnected with a vast web of secret societies throughout British India. However historian Peter Heehs concludes the links between provinces were limited to contacts between a few individuals like Aurobindo who was familiar with leaders and movements in Western India. He concludes the Maniktala society had links between the other groups and the Manicktalla society, such as the Anushilan and Atmannati Samitis, were more often competitive than co-operative. An internal circular of circa 1908 written by Pulin Behari Das, describes the division of the organisation in Bengal, which largely followed British administrative divisions, with central "Samitis" linked with a few small Samitis.
Indian independence movement
Within a short time of its inception, these organisations became the focus of an extensive police and intelligence operations. Operations against "Anushilan Samiti" saw founding of the Special branch of Calcutta Police. The intelligence operations against India House saw the founding of the Indian Political Intelligence Office which later grew to be the Intelligence bureau in independent India. Heading the intelligence and missions against Ghadarite movement and India revolutionaries was the MI5(g) section, and at one point invokved the Pinkerton's detective agency. Notable officers who led the police and intelligence operations against Indian revolutionaries, or were involved in it, at various time included John Arnold Wallinger, Sir Robert Nathan, Sir Harold Stuart, Vernon Kell, Sir Charles Stevenson-Moore and Sir Charles Tegart, as well as W. Somerset Maugham. The threat posed by the activities of the "Samiti" in Bengal during World War I, along with the threat of a Ghadarite uprising in Punjab, saw the passage of Defence of India Act 1915. These measures saw the arrest, internment, transportations and execution of a number of revolutionaries linked to the organisation, and was successful in crushing the East Bengal Branch. In the aftermath of the war, the Rowlatt committee recommended extending the Defence of India Act (as the Rowlatt act) to thwart any possible revival of the "Samiti" in Bengal and the Ghadarite movement in Punjab. In the 1920s, Alluri Sitarama Raju led the ill-fated Rampa Rebellion of 1922–24, during which a band of tribal leaders and other sympathisers fought against the British Raj. He was referred to as "Manyam Veerudu" ("Hero of the Jungles") by the local people. After the passing of the 1882 Madras Forest Act, its restrictions on the free movement of tribal peoples in the forest prevented them from engaging in their traditional "podu" (Slash-and-burn) agricultural system, which involved shifting cultivation. Raju led a protest movement in the border areas of the Godavari Agency in Madras Presidency (present-day Andhra Pradesh). Inspired by the patriotic zeal of revolutionaries in Bengal, Raju raided police stations in and around Chintapalle, Rampachodavaram, Dammanapalli, Krishna-devi-peta, Rajavommangi, Addateegala, Narsipatnam and Annavaram. Raju and his followers stole guns and ammunition and killed several British army officers, including Scott Coward near Dammanapalli. The British campaign lasted for nearly a year from December 1922. Raju was eventually trapped by the British in the forests of Chintapalli then tied to a tree and shot dead with a rifle.
