This is a collection of essays, written by members of the British Commission for Military History. They examine key aspects of the experience of US and British armies, ranging from the American Civil War to the most recent example of high-intensity manoeuvre war, to the Gulf Conflict of 1991. Leadership and command are the essential elements that allow an army to function effectively in war. The exercise of command in particular is an under-researched area, and the essays make a major contribution to the understanding of this vital topic. The book examines such key military commanders of the past 135 years as Ulysses S. Grant, Sir Douglas Haig, Orde Wingate and H. Norman Schwartzkopf. G.D. Sheffield is the author of The Redcaps: A History of the Royal Military Police and its Antecedents from the Middle Ages to the Gulf War.
