Dr. Mathra Singh after seeing off his younger brother Labh Singh at the Amritsar railway station, went back to the Chambal Bunga and began planning for the revolution. He frequently went to meet Gujjar Singh, whom he knew very well from his Shanghai days, who was staying at Nanak Singh’s chubara near the clock tower. The group of returned emigrants met daily to take stock of the situation. It was estimated that between five to eight thousand Ghadar Party workers had taken the passage home for the revolt. However, due to the spies of the british government who had infiltrated the party cadres, most of the returned emigrants were intercepted and either arrested immediately or interned in their villages with strict instructions to not venture out of village boundary and to report weekly at the local police station. Baba Sohan Singh Bhakna, Bhai Jawala Singh Thatian, Bhai Wasakha Singh, Bhai Kesar Singh Thatgarh, Master Udham Singh Kasel who were the central leaders of the Ghadar Party were arrested, among others, on their landing in India either at Calcutta or at Madras.
The ones who were able to slip through and evade arrest were the ones who still managed to work for the cause and included among these were, Dr. Mathra Singh, Harnam Singh Tundilat, Kartar Singh Sarabha, Amar Singh, Bhai Parmanand, Mula Singh, Gujjar Singh, Nidhan Singh Chugga and others. A total of about 200 people were estimated to be available for the cause, about a tenth of the original plan. The arms and ammunitions, that were expected to be received, did not come and fund-flow had dried up completely as in India it was not possible to channelize funds from Germany and other sympathizers worldwide.
Nevertheless, they did not lose heart and started planning for the revolt in right earnest. Meetings were held daily at various places to chalk out a program for the uprising. Recognizing the utmost need of the time was money, it was decided commit dacoities and the targets were to be the rich moneylenders, landed zamindars and other british sympathizers. For the arms and ammunitions, they decided to raid the local police stations, armory of the british army at various cantonments and from policemen. As it was getting impractical to stay at the Chambal Bunga due to its proximity with the Golden Temple and unsympathetic view of the Sikh clergy at the time, Dr. Mathra Singh shifted out and took up residence in a dharamshala in Amritsar run by the people of Wirpal in a kothri. Sant Gulab Singh used to run the dharamshala. Gujjar Singh also went back from Nanak Singh’s chubara near the clock tower where he was staying to his village Bhakna near Amritsar and organized meetings at the local railway station near Khasa and at Jhar Sahib Gurdwara. Together, these three meeting places witnessed the gathering of such brave and selfless men who had decided to sacrifice everything they had, including their lives, to bring freedom for their country.
