The Siege of Bastogne is one chapter in the history of the battle of the Ardennes. On December 16, 1944, the Germans launched their greatest offensive of the war in the west. Achieving a considerable success in their first attacks, they broke through, penetrated 65 miles into Allied territory, halted the Allied offensive then going on, and threatened the entire front in the west. The failure of this German drive was due in part to the American resistance at St. Vith and Bastogne.
The background of Bastogne dates from the fall of 1944. At that time three American armies, forming the 12th Army Group, were in position on the central part of the western front. The U. S. First and Third Armies were along the Siegfried Line and the U. S. Ninth Army was facing the Roer River in Germany some thirty miles from the Rhine. All three armies were pushing for the Rhine over difficult terrain, across swollen rivers, and against determined enemy resistance. Except in the Aachen sector, where an advance was made to the Roer, the line did not move during October and November. The Third Army fought near Metz; the First and Ninth Armies made their advance farther north, near Aachen. In between these two major efforts the First Army held an extensive line of defense. Of this line the southern and major part was maintained by the U. S. VIII Corps.
On December 16, VIII Corps, under the command of Major General Troy H. Middleton had its headquarters in Bastogne, Belgium. Its area extended from Losheim, Germany, north to a point where the Our River crosses the Franco-German border. Generally parallel to the German frontier along eastern Belgium and Luxembourg, its front was 88 miles wide. The country, the Ardennes, has rugged hills; there are high plateaus, deep-cut valleys and a restricted road net.
The mission that First Army gave VIII Corps was to defend this line in place. New divisions were brought into this part of the front for battle indoctrination, and battle-worn divisions were sent to VIII Corps for reequipment and rest. As divisions were rotated into the sector, they took over existing wire nets and other facilities.
