The Bangladesh War of Independence began in March 1971 as a regional war between the West Pakistan in the Middle East and the East Pakistan in Southeast Asia, which was geographically confined to East Pakistan. But gradually this war turned from an internal war to an Indo-Pakistani bilateral war and eventually turned into a battleground of the Cold War.The two Anglo-Saxon superpowers, the United States and Britain, and socialist China sided with Pakistan in the war.
In December 1971, the Bay of Bengal on the southern border of Bangladesh became a lake for the Indian and Soviet navies. From December 3, 1971, the Indo-Pakistani naval war began in full swing. The Pakistan Navy deployed in East Pakistan / Bangladesh was very weak and from the very first day of the war the British Navy aircraft carrier INS Vikrant of the Indian Navy laid siege to East Pakistan.
