The Seventy-Third Division was a unit of the United States Army that served during World War I. Activated in 1917, it was primarily composed of soldiers from the Midwestern United States. The division participated in several key battles, including the Meuse-Argonne Offensive, which was one of the largest military operations in American history. After the war, the Seventy-Third Division was inactivated in 1919. Its legacy continues through the National Guard and other military organizations that trace their roots back to this division. The division's contributions are remembered as part of the broader efforts of the U.S. military during the Great War.
