In January, 1942, a group of men that included Field Marshal Erwin von Witzleben, General Friedrich Olbricht, Colonel-General Ludwig Beck, Colonel-General Erich Hoepner, Colonel Mertz von Quirnheim, General-Major Henning von Tresckow, General-Major Hans Oster, General-Major Helmuth Stieff, Fabian Schlabrendorff, Wilhelm Leuschner, Ulrich Hassell, Hans Dohnanyi, Carl Goerdeler, Julius Leber, Peter von Wartenburg, Johannes Popitz and Jakob Kaiser, decided to overthrow Adolf Hitler. The conspiracy was called Operation Valkyrie. (1)
In October 1943, Lieutenant-Colonel Claus von Stauffenberg, joined the group. While serving in Africa, Stauffenberg was wounded in the face, in both hands, and in the knee by fire from a low-flying Allied plane. According to one source: "He feared that he might lose his eyesight completely, but he kept one eye and lost his right hand, half the left hand, and part of his leg." After he recovered it was decided that it would be impossible to serve on the front line and in October, 1943, he was appointed as Chief of Staff in the General Army Office. (2)
Claus von Stauffenberg volunteered to carry out the assassination himself. But before he took action he wanted to make sure he agreed with the type of government that would come into being. Conservatives such as Carl Goerdeler and Johannes Popitz wanted Field Marshal Erwin von Witzleben to become the new Chancellor. However, socialists in the group, such as Julius Leber and Wilhelm Leuschner, argued this would therefore become a military dictatorship. At a meeting on 15th May 1944, they had a strong disagreement over the future of a post-Hitler Germany. (3)
Stauffenberg was highly critical of the conservatives led by Carl Goerdeler and was much closer to the socialist wing of the conspiracy around Julius Leber. Goerdeler later recalled: "Stauffenberg revealed himself as a cranky, obstinate fellow who wanted to play politics. I had many a row with him, but greatly esteemed him. He wanted to steer a dubious political course with the left-wing Socialists and the Communists, and gave me a bad time with his overwhelming egotism." (4)
Peter Hoffmann has argued: "On Goerdeler's insistence he agreed that Goerdeler should be the main negotiator with Leber, Leuschner and their representatives. Goerdeler had already written a letter to Stauffenberg, transmitted through Kaiser, protesting against Stauffenberg negotiating independently with trade union leaders and socialists... This meant that Goerdeler should play the leading role in all non-military questions, as Beck was still insisting as late as July 1944. This he did not so much from suspicion of Stauffenberg as from aversion to exaggerated concentration of power. Moreover Stauffenberg was politically inexperienced; his views were vague; goodwill and idealism by themselves generally only do damage in politics. The fact that he was risking his life did not give Stauffenberg the right to claim power of political decision; Goerdeler and Beck were risking their lives too. The ability to murder Hitler was no adequate justification for assuming the role of political leader." (5)
To carry out the assassination, it was necessary for Stauffenberg to have access to Adolf Hitler. One member of the group, General Friedrich Fromm was Commander in Chief of the Reserve Army. His was in charge of training and personnel replacement for combat divisions of the German Army and had regular meetings with Hitler. It was agreed that a close friend of General Rudolf Schmundt, Hitler's chief adjutant, should suggest that Stauffenberg should become chief of staff to General Fromm. According to Albert Speer, "Schmundt explained to me, Stauffenberg was considered one of the most dynamic and competent officers in the German army. Hitler himself would occasionally urge me to work closely and confidentially with Stauffenberg. In spite of his war injuries (he had lost an eye, his right hand, and two fingers of his left hand), Stauffenberg had preserved a youthful charm; he was curiously poetic and at the same time precise, thus showing the marks of the two major and seemingly incompatible educational influences upon him: the circle around the poet Stefan George and the General Staff. He and I would have hit it off even without Schmundt's recommendation." (6)
On 1st July 1944 Stauffenberg was promoted to Colonel and became Chief of Staff to Fromm. Stauffenberg was now in a position where he would have regular meetings with Adolf Hitler. Fellow conspirator, Henning von Tresckow sent a message to Stauffenberg: "The assassination must be attempted, at any cost. Even should that fail, the attempt to seize power in the capital must be undertaken. We must prove to the world and to future generations that the men of the German Resistance movement dared to take the decisive step and to hazard their lives upon it. Compared with this, nothing else matters." (7)
Stauffenberg attended his first meeting with Hitler on 6th July. He had a bomb with him but for reasons that to this day are not entirely clear, he did not try to kill Hitler. The generally accepted theory is that Stauffenberg was dissuaded from acting because neither Heinrich Himmler or Hermann Göring were present. Several conspirators, including General Ludwig Beck, wanted these two men killed at the same time as Hitler. The theory being that Göring and Himmler would take power after the death of Hitler. (8)
On 11th July, Stauffenberg flew once more to Hitler's headquarters in Berchtesgaden. He had a bomb with him but did not set it off because Himmler and Göring were not at the meeting. According to Peter Hoffmann: "There was never any certainty that Himmler or Göring would be present at the briefing conferences; neither of them attended regularly. They were usually represented by their liaison officers who reported to them; they themselves came comparatively seldom. Sometimes Himmler and Göring had no personal contact with Hitler for weeks; at other times one of the other would attend several conferences with Hitler daily." (9) Stauffenberg remained committed to trying to kill Hitler although he had little confidence he would be successful. On 14th July he was quoted as saying: "The worst thing is knowing that we cannot succeed and yet that we have to do it, for our country and our children." (10)
Claus von Stauffenberg had another meeting with Adolf Hitler on 15th July. Although he had the bomb with him he did not take this opportunity to kill Hitler. The main reason was probably the difficulty he would have had in fusing his bomb. Since he only had three fingers on one hand he had to use a pair of pliers and this would certainly have been seen. It has been claimed that if he had bent down "to his briefcase and began to open it with his three fingers - someone would certainly have come to his assistance, lifted it on to the table and helped him take out the papers - impossible then to search round for the pliers, squeeze the fuse and put the briefcase back on the floor." (11)
Stauffenberg needed help in his task and his adjutant, Werner von Haeften, agreed to help assassinate Hitler, when he told his brother, the diplomat, Hans-Bernd von Haeften, also a member of the conspiracy, he raised objections on religious grounds. For sometime he had become entangled in a web of philosophical and religious reflection. He asked Werner: "Are you absolutely sure this is your duty before God and our forefathers?" Werner replied that the act was justified because it would bring an end to the war and would therefore save the lives of many Germans. (12)
Claus von Stauffenberg was now convinced that he was morally justified in taking this action. His religious and ethical beliefs led him to the conclusion that it was his duty to eliminate Hitler and his murderous regime by any means possible. Just before he left on his mission to kill Hitler he said: "It is now time that something was done. But he who has the courage to do something must do so in the knowledge that he will go down in German history as a traitor. If he does not do it, however, he will be a traitor to his conscience." (13)
Other members of the conspiracy also urged action. Colonel-General Ludwig Beck, who had been an integral part of the resistance from the beginning, continued to argue that the attempt must be made, regardless of the consequences. As Theodore S. Hamerow pointed out: "Some of those involved in planning the coup started to suggest that the attempt to overthrow the Nazi regime must be made not primarily to save Germany but as an act of atonement or expiation. Even if it should fail, even if the fatherland should be conquered and occupied, the resistance must wage its struggle against National Socialism as a moral obligation, as a sacrifice for mankind, as an appeal for forgiveness and redemption... What mattered was proving to the world that at least some Germans, acting out of conscience and in accordance with universal moral values, were willing to sacrifice themselves to protect humanity against an unspeakable evil." (14)
On 20th July, 1944, Stauffenberg and Haeften left Berlin to meet with Hitler at the Wolf' Lair. After a two-hour flight from Berlin, they landed at Rastenburg at 10.15. Stauffenberg had a briefing with Field Marshal Wilhelm Keitel, Chief of Armed Forces High Commandat, at 11.30, with the meeting with Hitler due to take place at 12.30. As soon as the meeting was over, Stauffenberg, met up with Haeften, who was carrying the two bombs in his briefcase. They then went into the toilet to set the time-fuses in the bombs. They only had time to prepare one bomb when they were interrupted by a junior officer who told them that the meeting with Hitler was about to start. Stauffenberg then made the fatal decision to place one of the bombs in his briefcase. "Had the second device, even without the charge being set, been placed in Stauffenberg's bag alone with the first, it would have been detonated by the explosion, more than doubling the effect. Almost certainly, in such an event, no one would have survived." (15)
When he entered the wooden briefing hut, twenty-four senior officers were in assembled around a huge map table on two heavy oak supports. Stauffenberg had to elbow his way forward a little in order to get near enough to the table and he had to place the briefcase so that it was in no one's way. Despite all his efforts, however, he could only get to the right-hand corner of the table. After a few minutes, Stauffenberg excused himself, saying that he had to take a telephone call from Berlin. There was continual coming and going during the briefing conferences and this did not raise any suspicions. (16)
Stauffenberg and Haeften went straight to a building about 200 hundred yards away consisting of bunkers and reinforced huts. Shortly afterwards, according to eyewitnesses: "A deafening crack shattered the midday quiet, and a bluish-yellow flame rocketed skyward... and a dark plume of smoke rose and hung in the air over the wreckage of the briefing barracks. Shards of glass, wood, and fiberboard swirled about, and scorched pieces of paper and insulation rained down." (17)
Stauffenberg and Haeften observed a body covered with Hitler's cloak being carried out of the briefing hut on a stretcher and assumed he had been killed. They got into a car but luckily the alarm had not yet been given when they reached Guard Post 1. The Lieutenant in charge, who had heard the blast, stopped the car and asked to see their papers. Stauffenberg who was given immediate respect with his mutilations suffered on the front-line and his aristocratic commanding exterior; said he must go to the airfield at once. After a short pause the Lieutenant let them go. (18)
According to eyewitness testimony and a subsequent investigation by the Gestapo, Stauffenberg's briefcase containing the bomb had been moved farther under the conference table in the last seconds before the explosion in order to provide additional room for the participants around the table. Consequently, the table acted as a partial shield, protecting Hitler from the full force of the blast, sparing him from serious injury of death. The stenographer Heinz Berger, died that afternoon, and three others, General Rudolf Schmundt, General Günther Korten, and Colonel Heinz Brandt did not recover from their wounds. Hitler's right arm was badly injured but he survived. (19)
The original plan was for Ludwig Beck, Erwin von Witzleben and Erich Fromm to take control of the German Army. However, General Erich Fellgiebel, sent a message to General Friedrich Olbricht to say that Hitler had survived the blast. The most calamitous flaw in Operation Valkyrie was the failure to consider the possibility that Hitler might survive the bomb attack. Olbricht told Hans Gisevius, they decided it was best to wait and to do nothing, to behave "routinely" and to follow their everyday habits. (20)
Stauffenberg arrived back in Berlin and went straight to see General Friedrich Fromm. Stauffenberg insisted that Hitler was dead. Fromm replied that he had just learnt from Field Marshal Wilhelm Keitel that Hitler had survived the bomb attack. Stauffenberg replied, "Field Marshal Keitel is lying as usual. I myself saw Hitler being carried out dead." He then admitted that he had planted the bomb himself. Fromm became very angry and declared that all the conspirators were under arrest, whereupon Stauffenberg retorted that, on the contrary, they were in control and he was under arrest. (21)
Shortly after the assassination attempt, Joseph Goebbels broadcast a communiqué over German radio, assuring the public that Hitler was alive and well and that he would speak to the nation later that evening. Goebbels began the broadcast with the following words: Today an attempt was made on the Führer's life with explosives... The Führer himself suffered no injuries beyond light burns and bruises. He resumed his work immediately." (22)
Albert Speer, minister of armaments, visited Goebbels soon after the broadcast. He described the scene outside: "The office windows looked out on the street. A few minutes after my arrival I saw fully equipped soldiers, in steel helmets, hand grenades at their belts and submachine guns in their hands, moving toward the Blandenburg Gate in small, battle ready groups. They set up machine guns at the gate and stopped all traffic. Meanwhile, two heavily armed men went up to the door along the park and stood guard there." However, Goebbels was not confident that he would not be arrested and carried with him some potassium cyanide capsules. (23)
Goebbels was safe because the July 1944 Plot had been so badly organized. No real attempt had been made to arrest the Nazi leaders or to kill them. Nor did they secure immediate control of the radio and telephone communications systems. This was surprising as weeks earlier the original plan included the seizure of the long-distance telephone office, the main telegraph office, the radio broadcasting facilities in and around Berlin, and the central post office. "Incomprehensibly, the conspirators did not carry out these actions with sufficient dispatch, and this produced utter and fatal confusion." (24)
Later that day, Goebbels told Heinrich Himmler: "If they hadn't been so clumsy! They had an enormous chance. What dolts! What childishness? When I think how I would have handled such a thing. Why didn't they occupy the radio station and spread the wildest lies? Here they put guards in front of my door. But they let me go right ahead and telephone the Führer, mobilize everything! They didn't even silence my telephone. To hold so many trumps and botch it - what beginners!" (25)
Sometime between 8:00 and 9:00 p.m., the cordon that the conspirators had established around the government quarter was lifted. Military units that initially had supported the conspirators were switching loyalties back to the Nazis. The main reason for this was the series of radio announcements that were broadcast throughout Germany. By 10.00 p.m., forces loyal to the government were able to seize control of central headquarters and General Friedrich Fromm was released and Claus von Stauffenberg and his followers were taken prisoner. (26)
Those arrested included Colonel-General Ludwig Beck, Colonel-General Erich Hoepner, General Friedrich Olbricht, Colonel Mertz von Quirnheim and Lieutenant Werner von Haeften. Fromm decided that he would hold an immediate court-martial. They were all found guilty and sentenced to death. Hoepner, an old friend, was spared to stand further trial. Beck requested the right to commit suicide. According to the testimony of Hoepner, Beck was given back his own pistol and he shot himself in the temple, but only managed to give himself a slight head wound. "In a state of extreme stress, Beck asked for another gun, and an attendant staff officer offered him a Mauser. But the second shot also failed to kill him, and a sergeant then gave Beck the coup de grâce. He was given Beck's leather overcoat as a reward." (27)
The condemned men were taken to the courtyard. Drivers of vehicles parked in the courtyard were instructed to position them so that their headlight would illuminate the scene. General Olbricht was shot first and then it was Stauffenberg's turn. He shouted "Long live holy Germany." The salvo rang out but Haeften had thrown himself in front of Stauffenberg and was shot first. Only the next salvo killed Stauffenberg and was shot first. Only the next salvo killed Stauffenberg. Quirnheim was the last man shot. It was 12.30 a.m. (28)
He carefully closed the windows and doors, and announced with some emphasis that he had a very serious matter to discuss with me. He brusquely waved aside my joking rejoinder. For the time being he had to ask me to spare him the embarrassment of my presence. When I started to remonstrate he interrupted me harshly. He then proceeded to heap reproaches on me as he paced excitedly up and down. I had been unbelievably indiscreet, quite unheard-of; as a matter of fact, "with all due deference", so had my wife. This was all known in certain places (the Gestapo), and they claimed even to have documents. He mist demand, more emphatically, that I correct this behaviour. I had no idea, he said, how people were after me (the Gestapo). every step I took was observed. I should certainly burn everything I had in the way of notes which covered conversations in which one or other had said this or that.
Roeder in his investigations used methods which we at the time used to call Gestapo methods. I knew that not only from what Frau Dohnanyi and Frau Muller told me after their release. He put them under great mental pressure by threatening to persecute their wives if they did not make statements. I also remember the notes smuggled out of prison by Dohnanyi stating that Roeder would stop at nothing to get his way.
Dohnanyi lived under constant threat that Roeder would hand him over to the Gestapo. I remember this very clearly because that would have led to Dohnanyi being tortured. None of us was under any illusion that subject to such appalling duress he might well be forced to make statements which could jeopardize the entire conspiracy against Hitler.
The assassination must be attempted, at any cost. Even should that fail, the attempt to seize power in the capital must be undertaken. We must prove to the world and to future generations that the men of the German Resistance movement dared to take the decisive step and to hazard their lives upon it. Compared with this, nothing else matters.
Erich Fromm: "What's been happening at General Headquarters?"
Wilhelm Keitel: "What do they say's happening?" Everything is normal here.
Erich Fromm: "I've had a report the Führer's been assassinated.
Wilhelm Keitel: "Nonsense. It's true an attempt's been made on his life. Fortunately, it failed. The Führer's alive and was only slightly injured. But where's your Chief of staff, Stauffenberg?
Erich Fromm: "Stauffenberg's not back yet."
Field-Marshal von Kluge had just returned there. When I went into his room I saw that he had in front of him an extract from the German Radio to the effect that an attempt had been made on the life of the Fuhrer, but that it had failed. Von Kluge told me that he had previously had two telephone messages from Germany, but without any indication of the sender's identity, which said: "The Fuhrer is dead and you must make a decision."
Kluge went on to say that, about a year before, Witzleben, Beck and others had come to his home to sound him about an approach to the Führer and how it should be conducted. He also said that he had made notes of these discussions.
While we were talking a telephone message from St. Germain was brought in. It said that an anonymous telegram had arrived there stating that Hitler was dead. Kluge was puzzled as to which of the statements were true, and wondered whether the Radio was merely putting out a false report. After some further discussion I put a telephone call in to General Warlimont, Jodl's deputy, at O.K.W. It was a long time before the call came through. Then the reply was merely that Warlimont was not available, as he was engaged with Keitel.
So von Kluge and I put our heads together, and discussed whom we could try next. We telephoned the Chief of the S.S. in Paris. He replied that he did not know anything beyond the radio announcement. We then telephoned General Stieff - the Chief of the Organization Department - at O.K.H. I knew Stieff well, but had no idea that he was in the inner circle of the conspiracy, as later emerged. Stieff at once asked: "Where did you get the news that the Führer was dead?" He added: The Führer is quite well, and in good spirits" - and then rang off. We felt very uneasy about this telephone call afterwards, realizing how suspicious it must have appeared in the circumstances.
Stieff's answer and manner were so curious as to suggest a likely explanation, and I remarked to von Kluge: "This is an attempt that failed." Von Kluge then said to me that, if it had succeeded, his first step would have been to order the discharge of the V I's against England to be stopped, and that his second step would have been to get in touch with the Allied Commanders.
Right forearm badly swollen, prescribed acid aluminum acetate compress. Effusion of blood on right shinbone has subsided. On back of third and fourth finger of left hand there is a large blister. Bandage. Occiput partly and hair completely singed, a palm-sized second-degree bum on the middle of the calf and a number of contusions and open flesh wounds. Left forearm has effusion of blood on interior aspects and is badly swollen; he can move it only with difficulty. He is to take Optalidons at once, and two tablespoons of Brom-Nervacit before going to sleep.
I'm finally getting optimistic. Now, at last, things are going well! They really are! Great News! An assassination attempt has been made on Hitler's life, and for once not by Jewish Communists or British capitalists, but by a German general who's not only a count, but young as well. The Fuhrer owes his life to "Divine Providence" he escaped, unfortunately, with only a few minor burns and scratches. A number of officers and Generals who were nearby were killed or wounded. The head of the conspiracy has been shot.
This is the best proof we've had so far that many officers and generals are fed up with the war and would like to see Hitler sink into a bottomless pit, so they can establish a military dictatorship, make peace with the Allies, rearm themselves and, after a few decades, start a new war. Perhaps Providence is deliberately biding its time getting rid of Hitler, since it's much easier, and cheaper, for the Allies to let the impeccable Germans kill each other off. It's less work for the Russians and British, and it allows them to start rebuilding their own cities that much sooner. But we haven't reached that point yet, and I'd hate to anticipate the glorious event
I will crush and destroy the criminals who have dared to oppose themselves to Providence and to me. These traitors to their own people deserve ignominious death, and this is what they shall have. This time the full price will be paid by all those who are involved, and by their families, and by all those who have helped them. This nest of vipers who have tried to sabotage the grandeur of my Germany will be exterminated once and for all.
I shall shoot myself. Probably only a few can imagine what fate would have befallen Germany if the plot had succeeded. I thank Providence and my Creator, but not because he has preserved me. My life is solely devoted to worry, to working for my people. I thank Him, rather, because He had made it possible for me to continue to shoulder these worries, and to pursue my work to the best of my abilities and according to my conscience.
To create order, I have appointed Himmler Commander of the Reserve Army. I am convinced that with the disappearance of this very small clique of traitors and conspirators we are finally creating in the homeland the atmosphere which the fighters at the front need.
It is unthinkable that at the front, hundreds of thousands, no millions, of good men should be giving their all while a small gang of ambitious and miserable creatures here at home tries perpetually to sabotage them. This time we are going to settle accounts with them in the way we National Socialists are used to doing.
When you receive these lines I shall be no more. I cannot bear the reproach that I have sealed the fate of the West through faulty measures, and I have no means of defending myself. I draw a conclusion from that and am dispatching myself where already thousands of my comrades are. I have never feared death. Life has no more meaning for me, and I also figure on the list of war criminals who are to be delivered up.
Our applications were not dictated by pessimism but by sober knowledge of the facts. I do not know if Field-Marshal Model, who has been proved in every sphere, will still master the situation. From my heart I hope so. Should it not be so, however, and your cherished new weapons not succeed, then, my Fuhrer, make up your mind to end the war. The German people have borne such untold suffering that it is time to put an end to this fnghtfulness. There must be ways to attain this end, and above all to prevent the Reich from falling under the Bolshevist heel.
We all made the discovery that a man can endure far more pain that he would have deemed possible. Those of us who had never learned to pray did so now, and found that prayer, and only prayer, can bring comfort in such terrible straits, and that it gives a more than human endurance. We learned also that the prayers of our friends and relatives could transmit currents and strength to us.
Imagine a room with a low ceiling and whitewashed walls. Below the ceiling a rail was fixed. From it hung six big hooks, like those butchers use to hang their meat. In one corner stood a movie camera. Reflectors cast a dazzling, blinding light. At the wall there was a small table with a bottle of cognac and glasses for the witnesses of the execution. The hangman wore a permanent leer, and made jokes unceasingly. The camera worked uninterruptedly, for Hitler wanted to see and hear how his enemies died. He had the executioner come to him, and had personally arranged the details of the procedure. "I want them to be hanged, hung up like carcasses of meat." Those were his words.
Field Marshal Witzleben freely admitted his part in the assassination attempt. He and the others were found guilty the next day and sentenced to hang that afternoon. Hitler had ordered that they be hung like cattle. "I want to see them hanging like carcasses in a slaughterhouse!" he commanded. The entire event was filmed by the Reich Film Corporation. Witzleben was first. Despite his poor showing at the trial, Witzleben met his death with courage and with as much dignity as was possible under the circumstances. A thin wire noose was placed around his neck, and the other end was secured to a meat hook. The executioner and his assistant then picked up the sixty-four-year-old soldier and dropped him so that his entire weight fell on his neck. They then pulled off his trousers so that he hung naked and twisted in agony as he slowly strangled. It took him almost five minutes to die, but he never once cried out. The other seven condemned men were executed in the same manner within an hour. They were followed over the next eight months by hundreds of others.
