Solution:The Indian National Army (INA) was the brainchild of Giani Pritam Singh Dhillon along with Major Fujiwara and on 15 July, 1942 the Indian National Army was formed under the leadership of Mohan Singh.Giani Pritam Singh became actively involved in the Indian Independence Movement and Gadar Party. He met with Iwaichi Fujiwara, who had even before the declaration of war by Japan, reached an agreement of collaboration with the Japanese at Bangkok in December 1941.
It was Giani Pritam Singh’s idea, working with Iwaichi Fujiwara, who released Indian soldiers who were asked to join an Indian National Army to fight for Indian independence.
These plans were started long before the war broke out, among a group of revolutionaries based in Bangkok. Thus, Capt. Mohan Singh was not the founder of INA but was only the first operational Commander of the INA.
He accepted the position on Giani Ji and Iwaichi Fujiwara’s insistence. The brains behind INA were Iwaichi Fujiwara and Giani Pritam Singh Dhillon.
