Bose was a very active participant in the activities of Indian National Congress. He faced many difficulties and hardships for the cause of his countrymen. He was put behind the bars many times. He was an extremist leader. He did not believe in the peaceful methods of Gandhi. He became Indian National Congress President in 1938. He called the people of India to take up arms against the British. But he soon resigned from the president ship of Congress because he felt that Gandhiji objected to his approach of gaining freedom. He founded the Forward Bloc in 1940. He organised the people of India under the banner of Forward Bloc and started violent struggle against the British.
Within no time he became popular among the masses. His growing popularity was a cause of concern for the British. To crush this, he was arrested and put to jail. Even in jail, the cause of freedom kept him active. He made contacts with friends and tried to influence public opinion. During his imprisonment he felt seriously ill. He had to go to Europe for treatment.
When he came back to India, he was again arrested. He went on hunger strike. Fearing his death he was put under house arrest. He was restless to see his country free from foreign rule. He, however, managed to escape Berlin and then Singapore. In Singapore, he formed the Indian National Army (INA). His clarion call ‘Give me blood and I will give you freedom’ encouraged many Indians to join the Indian National Army. A large number of people joined him when he gave call to ‘Dilli Chalo’.
The INA consisted of those military persons who had left the Indian army while fighting against the Japanese on the Burma front. Subhash Chandra Bose went to Japan. He strengthened the INA there. With its help he intensified his fight against the British. But his army was outnumbered by the well- equipped British army. This was a big constraint on the way to his achieving freedom. He had the strength of public support that was eagerly waiting to see their country free. Meanwhile when he was on his way to Japan, his plane crashed. His untimely and unexpected death proved hail to the brimming zeal and hopes to his followers.
Controversy and Subhash Chandra Bose had close relation. This continued even in his death. His death is a great mystery. There are various kinds of stories related to his death. Many inquiry commissions have been set up so far by various governments to find out the real cause of his death, but it cannot be solved. Many people even today believe that he is still alive. He has been kept captive somewhere. Whatever may have been the ultimate fate of this son of soil, he will certainly be remembered as a great nationalist. He completely devoted himself to the cause of countrymen. He gave the slogan of Jai Hind. He is popularly known as Netaji.
