Following the defeat of France in the Franco-Prussian War of 1870-71, the German Army began to construct a fortress line from Strasbourg to Luxembourg to protect their new territory, the centrepiece of which was the great Moselstellung (Moselle Position) of Metz / Thionville. Illustrated with rare photographs and full-colour cutaway artwork, this book examines the design and development of the fortress and analyses its use in combat, focusing particularly on the part it played in holding up General Patton's Third Army's advance across France in 1944.

Clayton Donnell has had a life-long fascination with the Brialmont forts built at Liège and Namur. He spent his early years living in Belgium, and often visited the sites of the forts. Over the years he has amassed a large collection of material relating to this period, and has translated much of it from French to English. He has previously written Fortress 60: The Forts of the Meuse in World War I (Osprey, 2006) co-written Modern European Military Fortifications, 1870-1950: A Selected Annotated Bibliography (Praeger, 2004), and has created websites on the forts of Liège and Namur, and the Maginot Line.
