The years 1907 and 1908 are ever memorable in the history of Bengal. The current of a new spirit had flowed in, inundating every nook and corner of the province. The soul of the nation became awake. A divine touch had just broken the eternal sleep of the nation. Lashed into action by the high-handed measures of Lord Curzon, the lethargy of the people died away, they tried for the first time to stand upon their own legs and boldly face the world without fear of death. In an evil moment Lord Curzon sanctioned the partition of Bengal against the united voice of the people. This led to the manifestation of a new spirit in Bengal. A heavy out-burst of Anti-European feeling followed; a strong hatred against every form of Europeanism, a revengeful attitude to their commerce and industry, a growing apathy to everything associated with them, led to the repudiation or abandoning immediate Anglicised past, and a new spirit entered into politics and created a mighty and dynamic yearning towards a truly national future. This had for its realisation at its basis Swaraj, National Education and Boycott.
Persecutions were inaugurated by the Bureaucratic Government. On the third of May 1908 in the still hours of night Srijut Aravinda Ghosh, the leader of the national movement of Bengal, along with other brilliant young men were arrested on a charge of being implicated in a conspiracy against the established government. Evidence of all sorts was piled up by the prosecuting counsel. At this critical moment Providence sent Chitta Ranjan to take up the case in defence of Aravinda and other accused. The prosecution dragged on for more than a year. For this long period Chitta Ranjan conducted the defence case at a great personal sacrifice. This celebrated conspiracy case pushed Chitta Ranjan into the fore front of the Calcutta Bar. For more than six months he was engaged in this case, and even for his house-hold expenses during these months, he had to incur a large debt. The acquittal of Aravinda at once raised the reputation of Chitta Ranjan in the eyes of his countrymen. After this he took up the defence of the famous Dacca Conspiracy case without charging any fees at a great personal loss and also volunteered to defend the boycott cases of Bengal earning thereby the lasting gratitude of the whole nation. Providence also rewarded him amply for his good work and from the very day that he came back to take up the broken threads of his High Court practice, he found himself on the high road to both fame and wealth.
