The 32nd Division was organized under War Department orders of July 18, 1917, from National Guard troops from Wisconsin and Michigan. Wisconsin furnished approximately 15,000 and Michigan 8,000 troops of all arms. Later 4,000 National Army troops from Wisconsin and Michigan were transferred to the Division shortly before it left for France. On August 4, 1917, Battery F, 121st Field Artillery regiment, was the first unit of the new division to arrive at Camp MacArthur. From that time until late in September troops continued to pour in as rapidly as railroad facilities could be provided to transport them from the north. The 1st Wisconsin Field Artillery regiment became the 121st Field Artillery, the heavy artillery regiment of the 57th Field Artillery Brigade. The Commanding Officer of the Wisconsin Artillery, Colonel Philip C. Westfahl, became Commander of the new regiment.

On September 19, 1917, the Regiment was redesignated as the 121st Field Artillery Regiment and assigned to the 57th Field Artillery Brigade as a part of the 32nd Division. In addition to the 32nd Division, the records indicated the 121st Field Artillery Regiment also supported the 3rd, 47th, 79th, and the regiment distinguished itself in six major campaigns: Aisne-Marne, Alsace, Champaign, Lorraine, Meuse-Argonne, and Oise-Aisne. Along with the General of the Armies John J. Pershing's personal commendation, the regiment received the battle streamer of the French Croix-de-Guerre with Silver Star embroidered Aisne-Marne and Oise-Aisne. The 121st Field Artillery Regiment was demobilized at Camp Grant, Ill., May 17, 1919.
