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.
Nankana massacre
The combined Jatha took a Hukamnama and started for the Gurdwara at about 10 PM on that night so as to reach there by early morning at "Amrit vela" (nectral hours). On the way 50 more Sikhs joined the "Shaheedi Jatha" and total number swelled to about 200.
At Chanderkot Jhal, Jathedar Lachhman Singh decided to wait for Kartar Singh Jhabber and his Jatha. They waited for a while in vain and finally Jathedar Dharowali decided to cancel the plan for further march to Nankana Sahib. But at this very moment, Jathedar Tehal Singh came forward and addressed the Shaheedi Jatha not to vacillate even for a moment from forward march since ""the prayers having already been said and the action plan having already been decided with Guru's word, it is now imperative for now to move forward"". Advising further that ""all the members shall keep cool even under extreme provocations"". From here-onwards, Jathedar Tehal Singh took over the supreme command of the Shaheedi Jatha and resumed the march to Nankana. By almost at "Amritvela", the Shaheedi Jatha reached the Railway-crossing near Nankana Sahib. Some of the Jatha members raced towards Darshani Deori to take possession of the Gurdawara, but at this very moment, Chaudhury Paul Singh Lyallpuri showed up "with the latest decision of Shiromani Committee advising to postpone the action for taking possession of the Gurdwara". Having conveyed the information, Bhai Paul Singh grabbed Jathedar Lachhman Singh from his waist behind and persuaded him not to proceed further. Once again, Jathedar Tehal Singh took the initiative and shaking Chaudhury Paul Singh forcefully off from the person of Jathedar Lachhman Singh, he once more challenged the Shaheedi Jatha to get ready for the sublime action. He once again spoke: "" Khalsa ji, the time is not to stop now, but to act. We have come here to achieve martyrdom under Guru's word. This is very un-Sikh-like to backout from one's commitment at the last moment" " Saying this, Tehal Singh walked with the Jatha towards the Gurdwara. Lachhman Singh and others repeatedly requested him to relent, but Tehal Singh stuck to his Ardās.
