This first incarnation of the Indian National Army was involved in operations of espionage in the Burma frontier which, according to some military historians and allied generals, threatened the moral of Indian troops and fed discontentment and was partly responsible for the failure of the first Burma offensive. Operatives of the INA were also landed in the Indian coast by submarine for planned espionage operations within India. Coming at the time that the Quit India Movement had raised turmoil within British India, the threat of the INA affecting British Indian troops and INA operatives mounting espionage within India saw the start of a propaganda campaign in the British Indian Army and a news ban on the unit that was not to be lifted till after the war ended.
