#JallianwalaBaghMassacre

2/ Brigadier General Reginald Dyer deployed his 50 troopers near the entrance of the Bagh and without warning, he opened fire which continued for 20 minutes. His contingent comprising of Indians and Gurkhas fired 1.650 rounds of 0.303 Lee Enfield rifles mark VI ammunition.

3/ Sir Michael O& #39;Dwyer was the lieutenant governor of Punjab when this happened. Even though he didn& #39;t order the massacre, his culpability was secured by a notorious missive sent in its wake approving what Dyer had done.
He was later assassinated by Shaheed Udham Singh.

4/ Sir Chettur Sankaran Nair, was the president of Indian National Congress, and later became a member of the viceroy& #39;s executive council. When the news of the massacre trickled down, he was ashamed to be a part of such a government and so he resigned.

5/ He wrote a book blaming O& #39;Dwyer for these atrocities. O& #39;Dwyer sued Sir Nair for defamation at the Court of the Kings bench in London. This case was followed worldwide and that resulted in the world coming to know of the Jallianwala Bagh massacre and O& #39;Dwyer& #39;s culpability.
