In 1939, Subash Chandra Bose resigned from the congress and organised Forward Bloc for a more vigorous national struggle. The government first imprisoned him, and thereafter kept him confined to his house under close watch. In 1941, Subash Chandra Bose escaped from India to Soviet Union for help. Later Soviet Union joined hands with allies. This made Bose to escape to Germany. In 1943 he reached Japan and organise an armed struggle against British rule with Japanese help.
In 1942 Capitan Mohan Singh formed INA comprising the captured Indian soldiers along with Indian Independence league of Rash Bihari Bose.  The idea of a liberation army was revived with the arrival of Subhas Chandra Bose in the Far East in 1943. In July, at a meeting in Singapore, Rash Behari Bose handed over control of the organisation to Subhas Chandra Bose.
In 1944 the INA tried to invade India through Imphal and Kohima but the campaign failed. The INA members were imprisoned and tried. People across the country, from all walks of life, participated in the movement against the INA trials.
Impacts
The role of the I.N.A. had far-reaching influences on the Indian political scene. When the stories of their remarkable courage and sacrifice came to the knowledge of the Indian people at the end of the war, the nation came under a fresh wave of revolutionary upsurge after Quit India movement. British Indian government could no longer rely on the Indian personnel for its civil administration and for armed forces to suppress national movement. The INA had shown patriotic ideas to the Indian army which was chief instrument of British rule in India. INA trails once again unite the all sections of the people in the society.
