This second book presents the reader with the Northern attack on part of the 6th Panzer army whose commitment in the Battle of Ardennes represented the "baptism of fire." By studying the thousands of archives on the American and German forces, the author revisits this division that must have been the main way through which Hitler hoped to reverse in his favour the outcome of the war. In this work, Philippe Guillemeot invites us to follow the ferocious and bloody cavalcade of the Kampfgruppen of the 1st SS-Panzer Division, the unsuccess of the "Hitler Youth" against the fierce resistance of the GI's, and the force of the II.SS-Panzerkorps. One chapter is clearly dedicated to the special operations schemed by the German parachutists and the ineffable Otto Skorzeny. 200 photos
