General of the Armies John J. Pershing (1860 1948) had a long and distinguished military career, but he is most famous for leading the American Expeditionary Forces in World War I. He published a memoir, My Experiences in the World War, and has been the subject of numerous biographies, but the literature regarding this towering figure and his enormous role in the First World War deserves to be expanded to include a collection of his wartime correspondence. Meticulously edited by John T. Greenwood, volume 2 of John J. Pershing and the American Expeditionary Forces in World War I, 1917 1919 covers the period of October 1 through December 31, 1917. During this time, Pershing focused his efforts on working with the French Ministry of War, the General Staff, and the field Army on training and equipping the AEF’s few available combat divisions for frontline service. Russia’s defection from the coalition and the surprising Italian defeat at Caporetto in October rocked the Allied ranks, and this volume addresses the creation of the Supreme War Council and the House’s American War Mission-bodies that reexamined the Entente’s military and diplomatic strategy and ultimately cemented the alliance. The correspondence also reveals how the House Mission revived the divisive issue of amalgamating arriving American troops into existing British and French combat divisions - something that Pershing utterly opposed and saw as a threat to the AEF. The dispute never resolved and irritated British prime minister Lloyd George and French premier Georges Clemenceau so much that both would try to engineer Pershing’s removal in the following year. Extracts from the large volume of rarely referenced cablegrams represent an important contribution to Pershing’s wartime story. AUTHOR: John T.
