St. Vith
The remnants of the division were reinforced by the 112th Infantry Regiment of the 28th Infantry Division and withdrew over the Our River and joined other units at Saint Vith. Along with the city of Bastogne to the south, St. Vith was a road and rail junction city considered vital to the German goal of breaking through Allied lines to split American and British forces and reach the Belgian port city of Antwerp. A scratch force of 106th Division personnel, in particular the division's 81st Engineer Combat Battalion, was organized and led by the 81st's 28-year-old commanding officer, Lt. Col. Thomas Riggs, in a five-day holding action (17–21 December) on a thin ridge line a mile outside St. Vith, against German forces vastly superior in numbers and armament (only a few hundred green Americans versus many thousands of veteran Germans). For this action, the 81st Engineer Combat Battalion was later awarded the Distinguished Unit Citation for gallantry. The defense of St. Vith by the 106th has been credited with ruining the German timetable for reaching Antwerp, hampering the Bulge offensive for the Germans.
