Indian participation
The Bangladesh Forces received assistance from the Indian authorities soon after hostilities started. On November 21, 1971, when the natural climate was more adaptable and by which time all Bangladesh Forces had severely under-cut the strength of the West Pakistani Forces, a demand of the Government of India was conceded to by the Bangladesh Government-in-exile in Calcutta, India, which was handing over the full command and authority of its operations to the Indian armed forces to command the war. The Indian Army entered Bangla Desh through air and land. The Pakistani force already morally broken and militarily devastated by the BD Forces, agreed to a cease fire without defiance in about one and a half weeks, on December 16, 1971.

The cease fire was switched to a surrender by the Indian government which the Commanding General of the Pakistan Army Eastern Command signed. Victory was declared by the Indian authorities and all prisoners of war including combat material were taken to India, with the Indian army remaining inside independent Bangladesh another three months until mid-March 1972. Bangladesh Forces were ordered for demobilization on January 29 under the direction of General M.A.G Osmani in final Sector Commanders Conference at the old Police HQ at Mintu Road, Dhaka, effective 14 February 1972.
