By this time the 168th Infantry, which had arrived in France eight months earlier, had spent 174 continuous days in combat and had suffered heavy casualties in repelling the German offensive of May 1918 and during the Meuse-Argonne counter-offensive that summer. Thus, many men from the 133rd Infantry were sent as replacements to the 168th infantry, and several of these were with the Rainbow Division in its final combat action of the war—the assault on Sedan 4–9 November 1918. Following the Armistice of 11 November, these same Sioux City soldiers also were part of the 168th Infantry's "watch on the Rhine,": being stationed at Niederzeissen, Germany, until 9 May 1919. Those men who had not returned from France immediately after the Armistice were finally shipped home from Germany, arriving at Camp Dodge on the 18th of May. The men received their discharges on 19 May 1919 and returned to Sioux City.
