The Jallianwala Bagh massacre occurred on 13th April 1919, when hundreds of innocent Indians were killed by troops of the British Indian Army, mostly Gurkhas, on orders of Brigadier-General REH Dyer.
The people had assembled peacefully to protest against the Rowlatt Act of 1919.
Jallianwala Bagh is a historic garden and memorial near the Golden Temple in Amritsar, Punjab.
On 13th April, which was Baisakhi, a large number of villagers unaware of the restrictions gathered at Jallianwala Bagh.
Dyer reached the spot with troops, blocked the only exit, and ordered firing on the unarmed crowd. Over 1,000 men, women, and children were killed.
