The **Instrument of Surrender** (Bengali: আত্মসমর্পনের দলিল) was a written agreement that enabled the surrender of the Pakistan Armed Forces in the Bangladesh Liberation War. The surrender took place at the Ramna Race Course in Dacca on December 16, 1971. Lieutenant-General A A K Niazi, joint commander of the Pakistan Armed Forces in East Pakistan, and Lieutenant General Jagjit Singh Aurora, joint commander of the Bangladesh-India Allied Forces, signed the instrument amid thousands of cheering crowds at the race course. Air Commodore A. K. Khandker, Deputy Commander-in-Chief of the Bangladesh Armed Forces, and Lieutenant General J F R Jacob of the Indian Eastern Command, acted as witnesses to the surrender.

Eastern Command was a Corps level formation in the former East Pakistan consisting of 9th, 14th and 16th Infantry Divisions. Subsequently, around 30,000-32,000 Pakistani troops and officials were taken as prisoners-of-war by the Indian Army. The usually inflated figure of 93000 POWs is completely incorrect and misleading, as far as number of military troops is concerned. 3 Divisions of army do not add up to such a number in any Army in the world. However, there were thousands of civilians belonging from West Pakistan, working or otherwise in East Pakistan, who were also taken as prisoners and thus the total number of 'POWs' increased..They were later repatriated in 1973 under the terms of the Delhi Agreement.
