Germany's Schlieffen Plan of the First World War is much talked of but little understood. Translations of primary sources recently available clarify the issues involved.

The great deficiency in the discussion of German war planning prior to the Great War has been the dearth of reliable primary sources. Practically nothing was made public before the German Reichsarchiv was destroyed in April 1945,and this problem is compounded for Anglophone historians by the fact that the most interesting secondary literature was printed in German periodicals in the early 1920s.

This book makes available in English translationmany of the documents concerning German war planning before 1914 that survived the war, but were kept closely guarded by the East German army archives, and only became available with the fall of the wall. Included are the only archival history of German war planning, Wilhelm Dieckmann's Der Schlieffenplan, Hellmuth Greiner's secret history of the German west front intelligence estimate from 1885 to 1914, and two of the younger Moltke's General Staff exercises. The book also presents other little-known documents found in other German archives as well as the most important parts of the 1920s literature concerning the debate on the German war plan.

The picture ofGerman war planning which now emerges is both more complex and more credible than the previous single-minded emphasis on the 'Schlieffenplan'.
