On July 20, 1944, Colonel Claus Schenk von Stuaffenberg tried to assassinate Adolf Hitler.

He had served with the Wehrmacht in Poland (1939), France (1940) and the Soviet Union (1941).

While serving in Tunisa, he was seriously wounded on April 7, 1943, when Allied fighters strafed his vehicle. He lost his left eye, right hand and two fingers of his left hand after surgery.

Nevertheless, he now acted as the prime mover for the conspiracy among a growing number of German high command officers to arrest or assassinate Germany’s Fuehrer.

For most of these officers, the motive was craven: The “happy time” of German victories was over. Germany was losing the war it had unleashed on the world in 1939—and now they feared the worst. 

This was especially true now that the numerically superior forces of the Soviet Union had gone onto the offensive.

For Stauffenberg, there was another reason: His disgust at the horrors he had seen committed by his fellow Wehrmacht soldiers upon defenseless POW’s and civilians in Russia.

Thus, Stauffenberg—more than many Germans–knew firsthand the vengeance his country could expect if the “Thousand-Year Reich” fell.

Something must be done, he believed, to prove to the world that not all Germans—even members of the Wehrmacht—were criminals.

Most of the conspirators wanted to arrest Hitler and surrender to British and American forces—well before the much-feared Russians gained a toehold in Germany.

Stauffenberg didn’t want to arrest Hitler; he wanted to kill him. A live Hitler might eventually be rescued by his Nazi colleagues.

But Hitler was a closely-guarded target. He was surrounded by fanatical bodyguards who were expert marksmen. He often wore a bulletproof vest and a cap lined with three pounds of laminated steel.

But his single greatest protection—he claimed—was an instinct for danger. He would suddenly change his schedule—to drop in where he was least expected. Or suddenly depart an event where he was expected to stay a long time.

That instinct had repeatedly saved his life.

A series of assassination attempts had been made against Hitler. All of them involved time-bombs. And all of the would-be assassins were members of the German General Staff.

In one case, a bomb secretly stashed aboard Hitler’s plane failed to explode. In another, an officer who had a bomb strapped to himself unexpectedly found his scheduled meeting with Hitler called off. He had to rush into a bathroom to defuse the bomb before it exploded.

Stauffenberg intended to carry his bomb—hidden in a briefcase—into a “Hitler conference” room packed with military officers. Rigged with a time-fuse, it would be left there while he found an excuse to leave.

After the explosion, he would phone one of his fellow conspirators with the news. 

Stauffenberg intended to direct the new government that would replace that of the Nazis—and open peace talks with the British and Americans.

With Hitler dead, the coup—“Operation Valkyrie”—would be on.

Anti-Nazi conspirators would seize control of key posts of the government. The British and Americans would then be informed of Germany’s willingness to surrender. Provided, of course, that the vengeance-seeking Russians did not have a say in its postwar future.

The Wehrmacht and Schutzstaffel (SS) had killed millions of Russians. Many had died in combat. Others had been murdered as captives. Still more had been allowed to die by starvation and exposure to the notorious Russian winter.

So the Germans—both Nazi and anti-Nazi—knew what they could expect if soldiers of the Soviet Union reached German soil.

On July 20, 1944, Stauffenberg appeared at Hitler’s well-guarded military headquarters in East Prussia.  Like all his other outposts, Hitler had named it—appropriately enough—“Wolf’s Lair.” 

“Wolf’s Lair”

Stauffenberg entered the large, concrete building while the conference was in session. He placed his yellow briefcase next to Hitler—who was standing with his generals at a heavy oaken table. Then he excused himself to take an “urgent” phone call.

After Stauffenberg left the room, Colonel Heinz Brandt, standing next to Hitler, found the briefcase blocking his legs. So he moved it—to the other side of the heavy oaken support, partially shielding Hitler from the blast.. 

At 12:42 p.m. on July 20, 1944, Stauffenberg’s briefcase bomb erupted. 

Brandt died, as did two other officers and a stenographer.  

Hitler not only survived, but the plotters failed to seize the key broadcast facilities of the Reich.  

This allowed Hitler to make a late-night speech to the nation, revealing the failed plot and assuring Germans that he was still alive. And he swore to flush out the “traitorous swine” who had tried to kill him.

Mass arrests quickly followed.

Among the first victims discovered and executed was the conspiracy’s leader, Colonel Claus von Stauffenberg. Standing before a makeshift firing squad at midnight, he cried: “Long live our sacred Germany!”

At least 7,000 persons were arrested by the Gestapo. Of these, 4,980 were executed.
