20th Division (United States)

There have been two 20th Divisions in the history of the United States Army.

In early 1917, the 20th Division was established as a National Guard formation consisting of units of the Idaho, Montana, Oregon, Washington, and Wyoming Army National Guards. On 1 April 1917, this division was activated for federal service as the 41st Division.

In August 1918, fourteen months after the American entry into World War I, another 20th Division was organized. This was a regular army and national army division intended for service in World War I. The Armistice of November 11, 1918 ended the war before the 20th Division departed for France, and it was demobilized in February 1919.

The 20th Division organized and trained at Camp Sevier, South Carolina. Its composition included the 39th Infantry Brigade (48th and 89th Infantry Regiments) and the 40th Infantry Brigade (50th, 90th Infantry Regiments), plus the 58th Artillery Regiment.
