It was the greatest single battle the U.S. Army ever fought. More than a million GIs were involved and nearly 80,000 became casualties. The Allied generals had to rally beaten, dispirited troops in the face of an attack they had never dreamed possible.A study in command, from generals to squad leaders, The Bitter Woods follows von Runstedt, Dietrich, and of course Hitler, as closely as the Americans. As son of the supreme commander Dwight D. Eisenhower, a West Point graduate, a retired Army brigadier general, and a military historian, John Eisenhower is uniquely qualified to tell how the Allied generals (nearly all of whom he knew personally) met Hitler's challenge how the two armies fought fiercely in the Ardennes from December 1944 to January 1945 and how the Allied victory broke the back of Nazi aggression.
