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. 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. Planned to eventually consist of nine corps, a total of five AEF corps and two unassigned divisions were in the field by September 1918. It was subsequently involved in the Occupation of the Rhineland.
