The agitation unleashed by the acts culminated on 13 April 1919 , in the Jallianwala Bagh massacre in Amritsar , Punjab when the British military commander , Brigadier-General Reginald Dyer , blocked the main entrance to the Jallianwallah Bagh , a walled-in courtyard in Amritsar , and ordered his soldiers to fire into an unarmed and unsuspecting crowd of some 5,000 people who had assembled there in defiance of a ban . A total of 1,650 rounds were fired , killing 379 people ( as according to an official British commission ; Indian estimates ranged as high as 1,500 ) and wounding 1,137 in the episode , which dispelled wartime hopes of home rule and goodwill in a frenzy of post-war reaction
