Battle of Argonne Forest took place from September 26th until November 11, 1918. It was part of the final Allied offensive (Meuse-Argonne) that culminated in ending the War. It involved the American Expeditionary Force under the command of “Blackjack” Pershing as well as the First and Second Armies. While the battle of Argonne Forest is not well remembered today, the offensive of which it was a part was the largest commitment of American troops in the war. While other individual days of war have been worse, it was the bloodiest single battle in American history in terms of those killed. The entire offensive included American losses of 117,000.
