Explanation:

The entry of India into the war was strongly opposed by Subhas Chandra Bose, who had been elected President of the Congress in 1938 and 1939, but later resigned due to differences in opinion with Gandhi.
After resignation he formed his own wing separated from the mainstream congress leadership known as Forward bloc which was the centre of ex-congressmen with socialist views; however he remained emotionally attached with him for the remainder of his life.
Bose then founded the All India Forward Bloc. In 1940, a year after war broke out, the British had put Bose under house arrest in Calcutta. However, he escaped and made his way through Afghanistan to Nazi Germany to seek Hitler and Mussolini's help for raising an army to fight the British.
