Indian National Army

The Indian National Army (INA; Azad Hind Fauj; Hindi: आज़ाद हिन्द फ़ौज; Urdu: آزاد ہند فوج‎) was an armed force formed by Indian nationalists in 1942 in Southeast Asia during World War II. The aim of the army was to secure Indian independence with Japanese assistance. Initially composed of Indian prisoners of war captured by Japan in the Malayan campaign and at Singapore, it later drew volunteers from Indian expatriate population in Malaya and Burma. The INA also was at the forefront of women's equality and the formation of a women's regiment, the Rani of Jhansi regiment was formed as an all volunteer women's unit to fight the British occupiers as well as provide medical services to the INA.

Initially formed in 1942 immediately after the fall of Singapore under Mohan Singh, the first INA collapsed in December that year before it was revived under the leadership of Subhas Chandra Bose in 1943 and proclaimed the army of Bose's Arzi Hukumat-e-Azad Hind (The Provisional Government of Free India). This second INA fought along with the Imperial Japanese Army against the British and Commonwealth forces in the campaigns in Burma, Imphal and Kohima, and later, against the successful Burma Campaign of the Allies. The end of the war saw a large number of the troops repatriated to India where some faced trial for treason and became a galvanising point of the Indian Independence movement.

The legacy of the INA is controversial given its associations with Imperial Japan, the course of Japanese occupations in Burma, Indonesia and other parts of Southeast Asia, its alliance with the Axis in Europe, as well as Japanese war crimes and the alleged complicity of the troops of the INA in these. However, after the war, the Red Fort trials of captured INA officers in India provoked massive public outcries in support of their efforts to fight for Indian independence against the Raj, eventually triggering the Bombay mutiny in the British Indian forces. These events in the twilight of the Raj are accepted by historians to have played a crucial role in its relatively rapid end.
