On 19 January 1941, Subhas Chandra Bose escaped in disguise from British surveillance in Calcutta to Kabul. There, he established contact with the German and Italian foreign ministries, thereby beginning a long period of collaboration with the Axis Powers to counter British rule in India. This led to the setting up of the Free India Centre, the radio station Azad Hind, and the Indian Legion in which 4,500 Indian volunteers were trained by German experts to fight for the freedom of their nation.
