The World Crisis is considered by many to be Winston S. Churchill's literary masterpiece. Published across five volumes between 1923 and 1931, Churchill here tells the story of The Great War, from its origins to the long shadow it cast on the following decades. At once a history and a first-hand account of Churchill's own involvement in the war, The World Crisis remains a compelling account of the conflict and its importance.

In the fifth and final volume of The World Crisis, Winston Churchill turns his attention to the 'forgotten war' on the Eastern Front. His focus is the great rivalry between Russia and the Austro-German alliance during the years of the First World War, from the tensions over Bosnia and Serbia that triggered the conflict through the terrible battles on the Eastern Front to the final collapse of the Russian forces that triggered the Revolution.
