1859–1928
A British Army officer turned influential military writer, he drew on field experience to write sharply observed studies of warfare, including the widely discussed Small Wars: Their Principles and Practice. His work helped shape how later readers understood imperial campaigns, military command, and the problems of irregular conflict.

by Sir C. E. (Charles Edward) Callwell
Born in 1859, Charles Edward Callwell built a career in the British Army and rose to the rank of major-general. He served in artillery, intelligence, and staff roles, and later worked at a high level during the South African War and the First World War.
Alongside his military service, he became known as a serious writer on military history, biography, and theory. He is best remembered for Small Wars: Their Principles and Practice (1896), a book that remained influential for many years because it tried to explain the realities of colonial and irregular warfare in a practical, systematic way.
Callwell died in 1928. Today he is often remembered less as a battlefield celebrity than as a soldier-scholar whose books gave later historians and officers a window into the ideas, assumptions, and methods of the British Army in his era.
