V. D. Savarkar (since 1906). In 1907, Chattopadhyaya was on the editorial board of Shyamji's Indian Sociologist. In August, along with Madame Cama and S. R. Rana, he attended the Stuttgart Conference of the Second International where they met delegates including Henry Hyndman, Karl Liebknecht, Jean Jaurès, Rosa Luxemburg and Ramsay MacDonald, among others. Vladimir Lenin attended, but it is not certain if Chattopadhyaya met him on this occasion. In 1908, at "India House" he came in contact with a number of important "agitators" from India: G. S. Khaparde, Lajpat Rai, Har Dayal, Rambhuj Dutt and Bipin Chandra Pal. In June 1909, at an India House meeting, V. D. Savarkar strongly advocated assassinations of the Englishmen in India. On 1 July, at the Imperial Institute in London, Sir William Curzon-Wyllie, political aide-de-camp at the India Office, was assassinated by Madan Lal Dhingra, who was deeply influenced by Savarkar. Chattopadhyaya published a letter in The Times on 6 July in support of Savarkar, and was promptly expelled from the Middle Temple by the Benchers. In November 1909, he edited the short-lived but virulent nationalist periodical Talvar (The Sword). In May 1910, seizing the opportunity of tension between the United Kingdom and Japan over the Korean peninsula, Chattopadhyaya discussed the possibility of Japanese help to Indian revolutionary efforts. On 9 June 1910, along with D. S. Madhavrao, he followed V. V. S. Aiyar to Paris, to avoid a warrant issued for his arrest. Upon reaching France, he joined the French Section of the Workers' International (SFIO). In Paris Aiyar returned to India and settled in Pondicherry where he published the Dharma newspaper and a number of political pamphlets in Tamil, while maintaining a regular contact with Madame Bhikaiji Cama in Paris. Chatto and some other revolutionaries stayed with her at 25 rue de Ponthieu and helped her to edit the Bande Mataram: its April 1911 issue "was one of the most violent that ever appeared," praising outrages in Nasik and Kolkata. It said: "With gentlemen we can be gentlemen, but not with rogues and scoundrels. (...) Our friends the Bengalis have also begun to understand. Blessed be their efforts. Long be their arms." In connection with the Tirunelveli Conspiracy Case in February 1912, Madame Bhikaiji Cama published an article showing that these political assassinations were in accord with the teachings of the Bhagavad Gita.
