This third volume of a mini-series covering the German forces in World War I examines the troops that fought during the climax of the war on all fronts: the last great battles of attrition in the West (Arras, Messines, 3rd Ypres Passchendaele/Langemarck and Cambrai, 1917) and the collapse of Russia in the East. The ‘Kaiserschlacht’ campaign is covered, as are the German operations in Italy, the Balkans, and in support of Turkey in the Middle East. Uniform changes during this period reflected the introduction of new tactics and weapons and new types of troops, such as tanks and assault battalions.
