1864–1927
Best remembered as the British officer behind the 1919 Jallianwala Bagh massacre, he also wrote a firsthand military memoir about campaigning on the Persian-Baluchi frontier during the First World War.

by R. E. H. (Reginald Edward Harry) Dyer
Born in 1864, Reginald Edward Harry Dyer served in the British Indian Army and later became one of the most notorious figures of the British Raj. His name is closely tied to the Jallianwala Bagh massacre at Amritsar in April 1919, when troops under his command fired on a large crowd, an event that drew lasting condemnation.
As an author, he is associated with Raiders of the Sarhad, an account of operations on the Persian-Baluchi border during the First World War. The book offers a direct, personal view of frontier warfare and helps explain why his name appears in older military and colonial history catalogs as R. E. H. Dyer.
He died in 1927. For modern readers, his writing is mainly of historical interest, especially for those exploring imperial military history and the contested legacy of British rule in India.
