This, the first of three volumes of Army Battlefield Guides, examines Waterloo (1815), Mons and Le Cateau (1914), the First and Third Battle of Ypres (1914 and 1917), and the Arras Counter-attack (1940). Each chapter gives a brief introduction which suggests why the battle is worth studying, followed by a longer background narrative which puts the action in its proper context. After a description of the battle, with appropriate conclusions, comes a section which relates the ground as it now lies to the events which took place upon it. The book is intended to be used by visitors to the areas who want to conduct their own battlefield tours.
