American Expeditionary Forces on the Western Front (World War I) order of battle

This is the American Expeditionary Forces on the Western Front order of battle. The American Expeditionary Forces (AEF) consisted of the United States Armed Forces (mostly the United States Army) that were sent to Europe in World War I to support the Allied cause against the Central Powers. During the United States campaigns in World War I the AEF fought in France alongside French and British allied forces in the last year of the war, against Imperial German forces. Some of the troops fought alongside Italian forces in that same year, against Austro-Hungarian forces. Late in the war American units also fought in Siberia and North Russia.[1]

President Woodrow Wilson created the AEF in May 1917, originally appointing Major General John J. Pershing, who was later promoted to general, as commander. Barely any American troops were sent to Europe in 1917, since Pershing ordered all AEF forces to be well-trained before going overseas.[2]

The troop ships used to transport the AEF were, at first, any ships that were available. Cruisers, German ships seized by the Navy, ships borrowed from the Allies, and many other ships were used to ship troops to Europe from ports in New York, New Jersey, and Virginia.[2] By June 1917, only 14,000 soldiers had made it to the front lines, but by May 1918 over two million American troops had reached Europe, with around half of them on the front lines.[3]

The AEF helped the French Army on the Western Front during the Aisne Offensive (at Château-Thierry and Belleau Wood) in June 1918, and fought its major actions in the Saint-Mihiel and Meuse–Argonne Offensives in late 1918.[4] Organized into two field armies (a third was forming as the war ended), it had a total strength of about two million men in Europe by the time of the Armistice.[5] Planned to eventually consist of nine corps,[6] a total of five AEF corps and two unassigned divisions were in the field by September 1918.[7][N 1] It was subsequently involved in the Occupation of the Rhineland.[10]

First Army edit

The First Army was officially organized and activated by General John J. Pershing on 4 July 1918, although it was technically formed when the United States entered the World War in 1917. It served in the Saint-Mihiel offensive, Lorraine offensive, Champagne offensive, and the Meuse–Argonne Offensive. It was finally demobilized and moved back to the United States on 30 April 1919.[11]

It attacked in the Lorraine area, and also around Saint-Mihiel, before later recapturing and liberating the Duchy of Luxemburg. It was demobilized on 15 April 1919, after the war had ended.[12]

Third Army edit

Following the defeat of Germany, Allied forces occupied the Rhineland under the terms of the Armistice. The United States provided around 240,000 men in nine veteran divisions, nearly a third of the total occupying force, for this task. These troops were organized into the Third Army, which was established by Pershing specifically for the purpose, under the command of Major General Joseph Dickman.[10]

I Corps edit

Lieutenant General Hunter Liggett took command of I Corps when it was created, almost one year after the Americans entered the war. It served through most of the battles that the American Expeditionary Forces fought on the Western Front.[13]

Assisted by the French XXXII Corps, I Corps was organized and activated on 15–20 January 1918. I Corps saw its first major action at the Battle of Chateau-Thierry, while seeing its first offensive action several days later at the Second Battle of the Marne. After serving briefly in the defensive sectors of Lorraine and Champagne, I Corps later served in the Battle of Saint-Mihiel and the Meuse–Argonne Offensive.[14] It was finally demobilized on 25 March 1919.[15]
