At the end of the war, Field Marshal Claude Auchinleck, then Commander-in-Chief of the Indian Army, drawing on experiences of the army during the war, led a committee to study various military academies around the world and submitted a report to the Government of India in Dec. 1946. The committee recommended the establishment of a Joint Services Military Academy, with training modelled on the United States Military Academy at West Point.
