The Definitive Account of the Battle of the Marne, One of World War I's Most Important Events "A masterly account of the First World War in the West."—John Keegan "A distinguished piece of historical writing."—Journal of Modern History "Admirable... clear and interesting."—Foreign Affairs "Direct and clear... it lays bare a most complicated course of events so that even the layman can follow."—New Republic Named as One of The 100 Best Nonfiction Books of the Twentieth Century With diplomacy unraveling during the summer of 1914, Germany swept into Belgium during the first week of August in an audacious attempt to catch France and England off guard. First contemplated after the Franco-Prussian War, the Schlieffen Plan was designed to keep Germany from fighting on two fronts. With a quick and decisive victory over France and its allies to the west, Germany could then confront Russia to the east. Despite the surprise of Germany's initial advance, the plan ultimately failed because it required much more mobile troops than were available at the time - something that would have to await the mechanized blitzkrieg of World War II—allowing France and British Expeditionary Forces to establish a tenacious defense. What followed was a stalemate along the Marne River and the beginning of four long years of destructive trench warfare that would only be lifted by a joint French, British, and American offensive across this same river plain in 1918. In The Campaign of the Marne, the entire genesis of the Schlieffen Plan, its modification, implementation, and the complex series of grueling battles that followed is laid out with the intent to make the entire episode comprehensible to the general reader. Hailed as one of the 100 best nonfiction books of the twentieth century by eminent military historian John Keegan, this is the first time the book has been available since its original publication in 1935.
