The agitation reached a peak in Amritsar (Punjab, India). In Amritsar, on 13th April 1919, about 10,000 Indians had assembled at Jallianwala Bagh. They had no idea of the law that they couldn't gather. The British military commander, Brigadier-General Reginald Dyer ordered his troops to fire at the civilians without any warning. The troops fired 1,650 times. Some historians estimate that the troops killed 379 and injured about 1,137 people. This incident came to be known as the Jallianwala Bagh massacre. With this killing of innocent people, the British lost the trust of the Indian people.
