Inside the headquarters of Eastern Command at Fort William in Kolkata, the museum, which is rarely opened to civilians, takes visitors down the memory lane with its historical collection.
The 1971 war had culminated in the historic surrender of over 93,000 Pakistani soldiers to the Indian armed forces and liberation of the then East Pakistan from the oppressive rule of Pakistan.
The 42nd anniversary of the war, which formally ended on December 16, 1971 with the surrender of Pakistani soldiers, was being celebrated today as Vijay Diwas with a delegation of Mukti Jodhas and senior Bangladeshi armed forces officers coming to Kolkata.
Another rare document is the instrument of surrender signed by Lt Gen Niazi, Commander of the Pakistani Forces in East Pakistan (Now Bangladesh), on December 16, 1971.
"The Pakistan Eastern Command agrees to surrender all Pakistan armed forces in Bangladesh to Lt General Jagjit Singh Aurora, the GOC-in-charge of the Indian and Bangladesh forces in the eastern theatre," reads the declaration of defeat.
