Book excerpt: The bomb that exploded in the "Wolf's Lair"—Hitler's command headquarters—on July 20th, 1944 was the closest any assassination attempt ever came to ridding the world of the Nazis' Führer. Pierre Galante's account of the years that led up to the attempt, and its grim aftermath, offers an illuminating look at how dissent among the German officer corps grew until something had to be done. Conspirator General Adolf Heusinger, who met with Hitler on hundreds of occasions, provides his personal accounts of the disintegrating obedience of the German commanders as the war turned against them. Their plan to kill Hitler, establish a provisional government, and negotiate with the Allies for peace—known as Operation Valkyrie—is described here in depth.
