 Ardennes - An Executive Summary

Early on 16 December 1944, the German Army - the Wehrmacht - began a massive counteroffensive smashing into US First Army lines in the wooded and hilly Ardennes Plateau in northern Luxembourg and eastern Belgium. Within ten days, German forces formed a large bulge in US lines, thus creating the popular name Battle of the Bulge for this lengthy and bloody battle that is more properly called the Ardennes Counteroffensive.

The Wehrmacht failed to attain its ambitious objectives and gradually began to retreat. In the Ardennes Counteroffensive, the Wehrmacht used up much of its reserves but delayed the planned Allied offensives to the east by at least six weeks.

Ardennes - An Informal Overview:
  • Two regiments of the US 106th Infantry Division, stationed on the front lines, were enveloped and then surrendered.
  • The US quickly brought in two reserve divisions, the 82nd Airborne and 101st Airborne, to bolster US forces. The 101st defended the road center of Bastogne, the 82nd was stationed further north. 
  • On 19 December, George Patton was authorized to move much of his Third Army north from Lorraine to shore up the south side of the bulge. Late on December 26, elements of the Third Army lifted the siege of Bastogne.
  • Elements of the US Ninth and British 2nd Armies were brought in to contain the north side and the leading edge of the bulge, while additional British 2nd units moved into blocking positions in case German units reached the Meuse River.
  • Bad weather kept Allied aircraft out of action for much of the time.
  • At its height, over a million Americans and Germans faced each other in the Battle of the Bulge.
  • The Battle of the Bulge is thought to be the 3rd deadliest battle in US history. 20,000 died, over 20,000 were captured, and 40,000 wounded. 
  • On the first map, note that the German 7th Army, which confronted the Allies in Normandy earlier in the year, had been reconstituted behind the Siegfried Line and was participating in a minor role in the attack.
  • The Ardennes Counteroffensive, although it did not achieve its goals, intensified the growing manpower shortage in the US Army. 80,000 Americans were casualties - killed, taken prisoner, wounded, suffering from  trenchfoot, etc.

The story of the siege of Bastogne at Christmas and  Patton's relief of Bastogne on December 26 cause many to believe that the Battle of the Buge ended in December 1944. In truth, long and bloody conflict continued through most of January as the territory seized by the German offensive in December was slowly recaptured. Of the eighteen men in my database who died in the Battle of the Bulge, nine died in January.

After 25 December, stiffening Allied resistance and Germany's shortage of gasoline eventually led to a slow German withdrawal. The bulge was closed by troops from the US First Army advancing from the northwest and the Third Army from the south around 16  January. The battle officially ended on 25 January.

​By early February, the mid-December Allied lines had been restored and the Allies were preparing to advance across the fortified Westwall and through the German Rhineland to the Rhine River. However, along most of the front, Allied advances in February were limited.  March 1945 would be a different story.
