The Pakistani Instrument of Surrender was a legal document signed between India and Pakistan to end the Bangladesh Liberation War and the Indo-Pakistani War of 1971. Per the trilateral agreement, the Pakistani government surrendered the Armed Forces Eastern Command, thereby enabling the establishment of the People's Republic of Bangladesh over the territory of East Pakistan. The document was signed by India's Lt. Gen Jagjit Singh Aurora and Pakistan's Lt. Gen. A. A. K. Niazi, and led to the surrender of 93,000 Pakistanis, of which about 34,000–45,000 were soldiers — one of the world's largest surrenders in terms of number of personnel since World War II. Despite the agreement, Pakistan did not formally recognize Bangladeshi sovereignty until February 1974.

Operation Python, a follow-up to Operation Trident, was the code name of a naval attack launched on West Pakistan's port city of Karachi by the Indian Navy during the Indo-Pakistani War of 1971. After the first attack during Operation Trident on the Port of Karachi, Pakistan stepped up aerial surveillance of its coast as the presence of large Indian Navy ships gave the impression that another attack was being planned. Pakistani warships attempted to outsmart the Indian Navy by mingling with merchant shipping. To counter these moves, Operation Python was launched on the night of 8/9 December 1971. A strike group consisting of one missile boat and two frigates attacked the group of ships off the coast of Karachi. While India suffered no losses, Pakistani fleet tanker PNS Dacca was damaged beyond repair, and the Kemari Oil Storage facility was lost. Two other foreign ships stationed in Karachi were also sunk during the attack.
