Hemchandra Kanungo

Hemachandra decided that what was needed was technical know-how, and he went to Europe to get it. He sold his house in Calcutta to arrange money for the trip. Arriving in Marseille toward the end of 1906, he spent a few months trying to get in contact with revolutionaries, or people who knew revolutionaries, in Switzerland, France, and England. Finally, he found a backer to support him while he studied chemistry in Paris. Someone introduced Joseph Albert, known as Libertad, to Hemchandra and his friend Pandurang Bapat in July 1907. With the help of a female anarchist, apparently Emma Goldman, they were admitted to a party headed by a mysterious Russian known as Ph.D. During the latter part of 1907, the two Indians studied history, geography, economics, socialism, communism, and finally, the subjects they had come to learn - explosive chemistry and revolutionary organization.

Hemchandra returned from Europe with a trunk full of up-to-date technical literature, the most important item of which was a seventy-page manual on bomb-making, translated from the Russian. Hemchandra had not intended to join forces with Barindra, but after a talk with Sri Aurobindo, agreed to cooperate.[2]

A suicide squad of two members was sent to kill Kingsford at Muzaffarpur. After bombing at wrong target, Prafulla Chaki committed suicide before the British Indian Police detained him alive but Khudiram Bose failed to commit suicide in time and the Police arrested him. As a result of this incident, the covert bomb factory established by Hemchandra was raided by the British Police and shut down. Almost all of the members were arrested in a short period of time.
