World War I The 29th Division was constituted on paper on 18 July 1917, three months after the
American entry into World War I, in the
National Guard. Troops came from
Delaware,
Maryland,
New Jersey,
Virginia, and
Washington, D.C. As the division was composed of men from states that had units that fought for both the North and South during the
American Civil War, it was nicknamed the "Blue and Gray" division, after the blue uniforms of the
Union and the gray uniforms of the
Confederate armies. The division was organized as a unit on 25 August 1917 at
Camp McClellan, Alabama. In November, 1,000
draftees from Delaware, Maryland, New Jersey, and the District of Columbia joined the division, while in January 1918, the 1st Delaware Infantry was relieved from assignment to the division and used to form the separate 59th Pioneer Infantry Regiment. In May, remaining vacancies were filled by 5,000 more draftees from
New York,
New England, and the
Midwest. The division, commanded throughout its existence by Major General
Charles G. Morton, departed for the
Western Front in June 1918 to join the
American Expeditionary Forces (AEF). The division's advance detachment reached
Brest, France on 8 June. In late September, the 29th received orders to join the
U.S. First Army's
Meuse–Argonne offensive as part of the French XVII Corps. During its 21 days in combat, the 29th Division advanced seven kilometers, captured 2,148 prisoners, and knocked out over 250 machine guns or artillery pieces. Thirty percent of the division were casualties in the war, including 170 officers and 5,691 enlisted men were
killed or
wounded. Shortly thereafter the
Armistice with Germany was signed on 11 November 1918, ending hostilities between the
Central Powers and the
Allied Powers. The division returned to the United States in May 1919. at a review in Alsace, France, 1918
