In August 1914 the mobilization of Imperial Germany's 800,000-strong army ushered in the first great war of the modern age - a war which still stands as the greatest slaughter of soldiers in history. That German Army is also the best example of a particular period of military thought, when virtually the whole manpower of the European nations was integrated into mass conscript armies, supported by several age categories of reservists and by dedicated industrial and transport systems. In this first of three volumes the author offers an extraordinary mass of information, in text and tables, illustrated by photographs and color plates.
