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.
Emperor vs Aurobindo Ghosh and others
The hearings against the accused had continued through May with intermittent recesses. However, despite a considerable body of evidence against most of the accused, very little evidence existed against Aurobindo himself. The structure of "Anushilan samiti" prevented the higher echelons of the organisation from becoming familiar to the junior ranks, and Aurobindo's involvement in the organisation and its activities were hard to pinpoint, except for a few letters and correspondences confiscated at Barin's Manicktolla garden house. These included letters Bain had written in 1907, initialled "A.G." proclaiming the time to distributing "sweets" across India, a euphemism for bombs of which the technology Hem Chandra had learnt in Paris. On the other hand, much of the aim of the prosecution was to gain conviction against Aurobindo, who was seen as the most dangerous individual driving the "Samiti" against the Raj. Unable to identify stronger material evidence, the prosecution began an effort to obtain witnesses who may be able to implicate Aurobindo. Their target became a young Anushilanite by the name of Naren Goswami. Goswami belonged to the family of a landowner in Bengal, of a wealthy background and social standing. He had been arrested at Maniktala with Barin and others on the initial raid. On 22 June, Prosecutor Norton announced to the court that Narendranath Goswami had turned "King's witness", or prosecution witness, in return for a pardon. By the middle of August, Birley had heard evidence against the accused. He twice rejected the defence's requests to cross-examine Goswami, using discretionary powers granted to him by the government of Bengal. On 19, 31 August prisoners were committed to stand trial at Alipore Sessions Court for waging war against the King. On the evidence against Aurobindo, Birley concluded that letters and correspondences from members of the group- particularly one letter from Barin where he had referred to "distributing sweets" across India- indicated prima facie involvement on Aurobindo's part.
