The Indo-Pakistani War of 1971, a major conflict between India and Pakistan, is closely associated with Bangladesh Liberation War (sometimes also referred to as Pakistani Civil War).

There is an argument about exact dates of the war.

However, hostilities commence officially between India and Pakistan on the evening of December 3, 1971.

The armed conflict on India's western front during the period between 3 December 1971 and 16 December 1971 is called the Indo-Pakistani War by both the Bangladeshi and Indian armies.

The war ends in a defeat for the Pakistani military after being faced on two fronts.
