What happened in Jallianwala Bagh massacre.

The Jallianwala Bagh massacre, also known as the Amritsar massacre, took place on April 13, 1919, in the northern Indian city of Amritsar, Punjab. The incident occurred when British Indian Army troops under the command of General Reginald Dyer fired on a crowd of unarmed Indian civilians who had gathered at the Jallianwala Bagh public garden to participate in a peaceful protest against British colonial rule.

The crowd, which included men, women, and children, had gathered at the garden to protest against the arrest and deportation of two Indian nationalist leaders, Satya Pal and Saifuddin Kitchlew. The gathering was peaceful, and the protesters had no weapons. However, General Dyer, without warning or provocation, ordered his troops to open fire on the unarmed crowd, trapping them in the enclosed garden with no means of escape.

The firing lasted for about ten minutes, resulting in the deaths of at least 379 people and injuring more than a thousand others. The British authorities later attempted to cover up the incident and prevent the news from spreading, but the event sparked widespread outrage and condemnation in India and around the world.

The Jallianwala Bagh massacre became a turning point in India's struggle for independence from British colonial rule, and it further fueled the nationalist movement. It also led to the formation of the Non-Cooperation Movement, which was launched by Mahatma Gandhi in 1920.
