On 13 April 1919, in Amritsar in the Punjab, India, 50 soldiers under the command of the British General Dyer opened fire on a crowd gathering in the Jallainwala Bagh – a garden-cum-open area popular for meetings and social or religious gatherings.
Many of the crowd were there to celebrate Vaisakhi, the Sikh New Year. No one was armed, there were no disturbances, it was peaceful.
The British authorities put the number of dead at 379, with more than a thousand injured. The actual number of fatalities will never be known.
