New Year’s Day 1945 marked the start of the Allied counter-offensive in the Northern Sector, with the US First Army attacking to push back the German salient and link up with Third Army near Houffalize. The Luftwaffe launched Operation Bodenplatte against fifteen Allied airfields, achieving tactical surprise but suffering catastrophic losses of 277 aircraft and 60 experienced pilots. The Germans also launched Operation Nordwind against the US Seventh Army in northern Alsace, forcing the thinly-stretched army to fall back.
VII Corps launched its offensive eastward toward Houffalize, with XVIII Airborne Corps protecting its left flank. Near Chenogne, American forces committed a reprisal killing of German prisoners, reflecting the brutalisation of combat following German atrocities during the offensive.
