The American Expeditionary Forces (A.E.F. or AEF) was a formation of the United States Army on the Western Front of World War I. The AEF was established on July 5, 1917, in France under the command of Gen. John J. Pershing. It fought alongside French Army, British Army, Canadian Army, and Australian Army units against the Imperial German Army. A minority of the AEF troops also fought alongside Italian Army units in that same year against the Austro-Hungarian Army.
