The communist infiltration of the revolutionary movement was a matter of concern to its leaders. Here is a letter from Rashbehari Bose to Sachin Sanyal 1938. It also tells us about the links to Japan before the war. 1/n

On the second page, Rashbehari clearly talks of how the British were quite happy to use communists to break the freedom movement in order to perpetuate their rule. Although his great faith in a benign Japan may have been misplaced. 2/n

It should be clear that Indian revolutionaries were more than aware of how the colonial government was using British communists like Rajni Palme to infiltrate their movement. The writer Yashpal is just one example of a planted informant. 3/n

Here is another letter where Rashbehari tells Sachin Sanyal to support Netaji within the Congress. Contrary to popular belief, there were many revolutionaries in the Congress and it is with their support that Netaji won against the Gandhians. 3/n

In 1938, Sachin Sanyal was released after a decade in prison. Rashbehari wrote a letter of introduction to GD Birla. Few know that GD Birla had helped the revolutionaries in the 1914 by hiding guns stolen from the Rodda arms heist. 4/n
