Reginald Dyer

Colonel Reginald Edward Harry Dyer, CB (9 October 1864 – 23 July 1927) was a British military officer in the Bengal Army and later the newly constituted British Indian Army. His military career began in the regular British Army, but he soon transferred to the presidency armies of India.

As a temporary brigadier-general, he was responsible for the Jallianwala Bagh massacre that took place on 13 April 1919 in Amritsar (in the province of Punjab). He has been called "the Butcher of Amritsar", because of his order to fire on a large gathering of people. The official report stated that this resulted in the killing of at least 379 people and the injuring of over a thousand more. Some submissions to the official inquiry suggested a higher number of deaths. After the massacre, he served in the Third Anglo-Afghan war, where he lifted the siege at Thal and inflicted heavy casualties on Afghans.

Dyer later resigned. He was widely condemned for spearheading the Jallianwala Bagh massacre, both in Britain and India, but he became a celebrated hero among some with connections to the British Raj.
