The seventh day of Unternehmen Wacht am Rhein marked the end of the offensive’s initial phase. After six days of hard fighting, the enemy had penetrated American lines almost 50 miles, but the offensive was now almost three days behind schedule. Kampfgruppe Peiper was trapped at La Gleize with no prospect of relief, while the 2. Panzer-Division’s reconnaissance battalion reached Celles, four miles from the Meuse–the deepest German penetration of the Bulge.
The 30th Infantry Division recaptured Stoumont, completing the isolation of Kampfgruppe Peiper. At Bastogne, Brigadier General McAuliffe delivered his famous “Nuts!” reply to the German surrender demand. Patton’s III Corps drove north toward Bastogne, having disengaged three divisions from combat and launched them over one hundred miles of icy roads into the German offensive.
