First Indian National Army

The First Indian National Army (First INA) was the Indian National Army as it existed between February and December 1942. It was formed with Japanese aid and support after the Fall of Singapore and consisted of approximately 12,000 of the 40,000 Indian prisoners of war who were captured either during the Malayan campaign or surrendered at Singapore. It was formally proclaimed in April 1942 and declared the subordinate military wing of the Indian Independence League in June that year. The unit was formed by Mohan Singh.^[1][2] The unit was dissolved in December 1942 after apprehensions of Japanese motives with regards to the INA led to disagreements and distrust between Mohan Singh and INA leadership on one hand, and the League's leadership, most notably Rash Behari Bose. Later on, the leadership of the Indian National Army was handed to Subhas Chandra Bose. A large number of the INAs initial volunteers, however, later went on to join the INA in its second incarnation under Subhas Chandra Bose.

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 morale 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.
