The Battle of Hilli were two major battles fought from 22 to 24 November and again from 10 to 11 December 1971. They are generally regarded as the bloodiest battles of the eastern front of the Indo-Pakistani War of 1971. The first battle saw, according to veterans of the battle, the fiercest fighting of the war, but the second was much tamer. The Indian objective was to capture a network of Pakistani fortifications centred around the village of Hilli to allow for an advance on the town of Bogra.
