Even after more than a century of analysis, it is surprising how many gaps there are in our understanding of US land forces on the Western Front, so this sparkling collection of essays is especially welcome. A distinguished team of contributors deliver scholarship and controversy in a highly accessible form. Pershing's Lieutenants goes straight onto any list of key books on American military history in the Great War.

Professor Gary Sheffield, co-director of the First World War Research Group

The essays in this excellent collection, written by some of the brightest stars in the military history galaxy, shed a new and exciting light on one of the least understood armies of the First World War. It is not just historians who will find them useful, though: today's soldiers, sailors and airmen, too, will learn much from the insights on leadership they offer.

Dr Jonathan Boff, author of Haig's Enemy: Crown Prince Rupprecht and Germany's War on the Western Front

This is a superb collection of essays by nineteen eminent scholars covering twenty-two American “lieutenants” ranging from Lieutenant General Hunter Liggett to Major Harry S. Truman. From honing technical skills to alliance building, the “lieutenants” struggled to master a deadly battlefield. The writing is crisp, the analysis critical, and the tone compassionate. The book is a welcome complement to Douglas Southall Freeman's Lee's Lieutenants, Steven Woodworth's Grant's Lieutenants, and Russell Weigley's Eisenhower's Lieutenants.

Behind every great captain of war stand typically over-looked but essential lieutenants, who enable the planning and conduct of operations made famous by their superior commander. This new volume, expertly edited by David T. Zabecki and Douglas V. Mastriano, brings Pershing's illustrious and largely-forgotten subordinates out of the shadows into the limelight they deserve.

April 1917 saw the U.S. military largely unprepared for participation in World War I. In this important study edited by Douglas V. Mastriano and David T. Zabecki, and bound to be required reading for military officers, 19 military historians trace the service of, and lessons learned, in that conflict by 22 key figures from future Army chiefs of staff and Marine Corps commandants, to specialists and regimental commanders.
