This is a history of World War I, seen through the eyes of Sir Henry Rawlinson, a middle-ranking commander who frequently acted under General Haig. By examining Rawlinson's role in the War, the authors are able to follow the actual events of the battlefield and show how they related to the strategies of the High Command. Rawlinson kept a diary in which he recorded his views on tactics and the day-to-day events of the conflict. The authors use the content of the diary as the basis of detailed discussions on night attacks, poison gas, the introduction of the tank, hurricane bombardment and creeping barrages.

Command on the Western Front is not a biography, nor is it psychohistory. Rather, it uses Rawlinson as a lens through which to study the tactics of the time - tactics that usually proved woefully inadequate in dealing with the defensive positions that characterized industrial warfare.
