Hugh M. Cole, The Ardennes: Battle of the Bulge… (1965)
“ Horse-drawn artillery was mixed up with armored vehicles, the roads had been pounded to sloughs, and the German timetable for advance in this sector had gone out the window. In the early evening Bayerlein himself led the advance guard of the Panzer Lehr (four companies of the 902d Panzer Grenadier Regiment and some fifteen tanks) into Niederwampach. On the march the advance guard had heard the sounds of battle and seen gunfire flaming to the north, "an impressive sight," Bayerlein later recalled. This was the 2d Panzer Division destroying the Allerborn roadblock defense. ”
