Lasting six brutal weeks, from December 16, 1944, to January 25, 1945, the assault is also called the Battle of the Ardennes. It took place during freezing weather, with some 30 German divisions attacking battle-fatigued American troops across 85 miles of the densely wooded Ardennes Forest.
A Powerful German Blitzkreig
As the German blitzkreig drove into the Ardennes, their front line took on the appearance of a large, protruding bulge, giving the battle its name.
The formerly serene, wooded region of Ardennes was hacked into chaos by fighting as the Americans dug in against the German advance at St.-Vith, Elsenborn Ridge, Houffalize and, later, Bastogne, which was defended by the 101st Airborne Division.
“Did you ever see land when a tornado’s come through? Did you ever see trees and stuff, twisted and broken off? The whole friggin’ forest was like that,” veteran Charles Sanderson told author Charley Valeran My Father’s War: Memories from Our Honored WWII Soldiers.
U.S. Forces Suffer Horrific Losses
Allied forces along the Western Front—stretching from Amsterdam on the North Sea southeast to Basel, Switzerland—believed that German forces positioned along the front lines were massed there for defensive purposes only. They were tragically mistaken.
A surprise German attack quickly broke through the Allied front early on December 16, 1944, as Allied soldiers woke to a fierce artillery barrage, followed by some 1,000 German Panzer tanks. Gruesome stories quickly spread of massacred soldiers and civilians, according to the U.S. Army Center of Military History.
The bloody battle proved to be the costliest ever fought by the U.S. Army, which suffered over 100,000 casualties. “For those who had lived through 1940, the picture was all too familiar. Belgian townspeople put away their Allied flags and brought out their swastikas,” the center writes.
“Police in Paris enforced an all-night curfew. British veterans waited nervously to see how the Americans would react to a full-scale German offensive, and British generals quietly acted to safeguard the Meuse River's crossings. Even American civilians, who had thought final victory was near, were sobered by the Nazi onslaught.”
