sentences:  In February 1942, the Indian prisoners of war from the British Indian Army captured there came under the influence of Indian nationalists, notably Mohan Singh Deb, and a large number volunteered to form the Indian National Army with support from Japan and had the stated aim of overthrowing The Raj from India.Of the formation of this army however, the British intelligence was unaware of until around July 1942, and even then was unclear on the scale, purpose and organisation of the INA.Intelligence summaries initially did not believe the INA to be a substantial force or have any purpose more than propaganda and espionage purposes.
