The Night of the Long Knives (German: Nacht der langen Messer (help·info)), sometimes called Operation Hummingbird or, in Germany, the Röhm-Putsch, was a purge that took place in Nazi Germany between June 30 and July 2, 1934, when the Nazi regime carried out a series of political murders. Leading figures of the left-wing Strasserist faction of the Nazi Party, along with its figurehead, Gregor Strasser, were murdered, as were prominent conservative anti-Nazis (such as former Chancellor Kurt von Schleicher and Gustav Ritter von Kahr, who had suppressed Hitler's Beer Hall Putsch in 1923). Many of those killed were leaders of the Sturmabteilung (SA), the paramilitary brownshirts.

Adolf Hitler moved against the SA and its leader, Ernst Röhm, because he saw the independence of the SA and the penchant of its members for street violence as a direct threat to his newly gained political power. Hitler also wanted to conciliate leaders of the Reichswehr, the official German military who feared and despised the SA—in particular Röhm's ambition to absorb the Reichswehr into the SA under Röhm's leadership. Additionally, Hitler was uncomfortable with Röhm's outspoken support for a "second revolution" to redistribute wealth. (In Röhm's view Hitler's election had accomplished the "nationalistic" revolution but had left unfulfilled the "socialistic" motive in National Socialism.) Finally, Hitler used the purge to attack or eliminate critics of his new regime, especially those loyal to Vice-Chancellor Franz von Papen, as well as to settle scores with old enemies.

At least 85 people died during the purge, although the final death toll may have been in the hundreds,  and more than a thousand perceived opponents were arrested.  Most of the killings were carried out by the Schutzstaffel (SS) and the Gestapo (Geheime Staatspolizei), the regime's secret police. The purge strengthened and consolidated the support of the Reichswehr for Hitler. It also provided a legal grounding for the Nazi regime, as the German courts and cabinet quickly swept aside centuries of legal prohibition against extra-judicial killings to demonstrate their loyalty to the regime.

Before its execution, its planners sometimes referred to it as "Hummingbird" (German: Kolibri), the codeword used to send the execution squads into action on the day of the purge.  The codename for the operation appears to have been chosen arbitrarily. The phrase "Night of the Long Knives" in the German language predates the massacre itself and refers generally to acts of vengeance. Germans still use the term "Röhm-Putsch" to describe the murders, the term given to it by the Nazi regime, despite its unproven implication that the murders were necessary to prevent a coup. German authors often use quotation marks or write about the so-called Röhm-Putsch to emphasize this.

To a lesser extent, the Sturmabteilung (SA), a Nazi paramilitary organisation, remained somewhat autonomous within the party itself. The SA evolved out of the remnants of the Freikorps movement of the post-World War I years. The Freikorps were nationalistic organisations primarily composed of disaffected, disenchanted, and angry German combat veterans founded by the government in January 1919 to deal with the threat of a Communist revolution when it appeared that there was a lack of loyal troops. A very large number of the Freikorps believed that the November Revolution had betrayed them when Germany was alleged to be on the verge of victory in 1918. Hence, the Freikorps were in opposition to the new Weimar Republic, which was born as a result of the November Revolution, and whose founders were contemptuously called "November criminals". Captain Ernst Röhm of the Reichswehr served as the liaison with the Bavarian Freikorps. Röhm was given the nickname "The Machine Gun King of Bavaria" in the early 1920s, since he was responsible for storing and issuing illegal machine guns to the Bavarian Freikorps units. Röhm left the Reichswehr in 1923 and later became commander of the SA. During the 1920s and 1930s, the SA functioned as a private militia used by Hitler to intimidate rivals and disrupt the meetings of competing political parties, especially those of the Social Democrats and the Communists. Also known as the "brownshirts" or "stormtroopers", the SA became notorious for their street battles with the Communists.  The violent confrontations between the two contributed to the destabilisation of Germany's inter-war experiment with democracy, the Weimar Republic. In June 1932, one of the worst months of political violence, there were more than 400 street battles, resulting in 82 deaths. This destabilisation had been crucial in Hitler's rise to power, however, not least because it convinced many Germans that once Hitler became chancellor, the endemic street violence would end.
 

Hitler's move would be to strengthen his position with the army by moving against its nemesis, the SA. On July 6, 1933, at a gathering of high-ranking Nazi officials, Hitler declared the success of the National Socialist, or Nazi, brown revolution. Now that the NSDAP had seized the reins of power in Germany, he said, it was time to consolidate its control. Hitler told the gathered officials, "The stream of revolution has been undammed, but it must be channelled into the secure bed of evolution."

Hitler's speech signalled his intention to rein in the SA, whose ranks had grown rapidly in the early 1930s. This would not prove to be simple, however, as the SA made up a large part of Nazism's most devoted followers. The SA traced its dramatic rise in numbers in part to the onset of the Great Depression, when many German citizens lost both their jobs and their faith in traditional institutions. While Nazism was not exclusively – or even primarily – a working class phenomenon, the SA fulfilled the yearning of many unemployed workers for class solidarity and nationalist fervour. Many stormtroopers believed in the socialist promise of National Socialism and expected the Nazi regime to take more radical economic action, such as breaking up the vast landed estates of the aristocracy. When the Nazi regime did not take such steps, those who expected an economic as well as a political revolution were disillusioned.

Not content solely with the leadership of the SA, Röhm lobbied Hitler to appoint him Minister of Defence, a position held by the conservative General Werner von Blomberg. Although nicknamed the "Rubber Lion" by some of his critics in the army for his devotion to Hitler, Blomberg was not himself a Nazi, and therefore represented a bridge between the army and the party. Blomberg and many of his fellow officers were recruited from the Prussian nobility, and regarded the SA as a plebeian rabble that threatened the army's traditional high status in German society.

If the regular army showed contempt for the masses belonging to the SA, many stormtroopers returned the feeling, seeing the army as insufficiently committed to the National Socialist revolution. Max Heydebreck, a SA leader in Rummelsburg, denounced the army to his fellow brownshirts, telling them, "Some of the officers of the army are swine. Most officers are too old and have to be replaced by young ones. We want to wait till Papa Hindenburg is dead, and then the SA will march against the army."

Despite such hostility between the brownshirts and the regular army, Blomberg and others in the military saw the SA as a source of raw recruits for an enlarged and revitalised army. Röhm, however, wanted to eliminate the generalship of the Prussian aristocracy altogether, using the SA to become the core of a new German military. Limited by the Treaty of Versailles to one hundred thousand soldiers, army leaders watched anxiously as membership in the SA surpassed three million men by the beginning of 1934. In January 1934, Röhm presented Blomberg with a memorandum demanding that the SA replace the regular army as the nation's ground forces, and that the Reichswehr become a training adjunct to the SA.

In response, Hitler met with Blomberg and the leadership of the SA and SS on February 28, 1934. Under pressure from Hitler, Röhm reluctantly signed a pledge stating that he recognised the supremacy of the Reichswehr over the SA. Hitler announced to those present that the SA would act as an auxiliary to the Reichswehr, not the other way around. After Hitler and most of the army officers had left, however, Röhm declared that he would not take instructions from "the ridiculous corporal" – a demeaning reference to Hitler. While Hitler did not take immediate action against Röhm for his intemperate outburst, it nonetheless deepened the rift between them.

As a means of isolating Röhm, on April 20, 1934, Göring transferred control of the Prussian political police (Gestapo) to Himmler, who, Göring believed, could be counted on to move against Röhm. Himmler envied the independence and power of the SA, although by this time he and his deputy Reinhard Heydrich had already begun restructuring the SS from a bodyguard formation for Nazi leaders (and a subset of the SA) into its own independent elite corps, one loyal to both himself and Hitler. The loyalty of the SS men would prove useful to both when Hitler finally chose to move against Röhm and the SA. By May, lists of those to be "liquidated" started to circulate amongst Göring and Himmler's people, who engaged in a trade, adding enemies of one in exchange for sparing friends of the other. At the end of May, two former Chancellors Heinrich Brüning and Kurt von Schleicher received warnings from friends in the Reichswehr that their lives were in danger, and they should leave Germany at once.Brüning fled to the Netherlands while Schleicher dismissed the tip-off as a bad practical joke.  By the beginning of June, everything was set, and all that was needed was permission from Hitler.

In response to conservative pressure to constrain Röhm, Hitler left for Neudeck to meet with Hindenburg. Blomberg, who had been meeting with the President, uncharacteristically reproached Hitler for not having moved against Röhm earlier. He then told Hitler that Hindenburg was close to declaring martial law and turning the government over to the Reichswehr if Hitler did not take immediate steps against Röhm and his brownshirts.  Hitler had hesitated for months in moving against Röhm, in part due to Röhm's visibility as the leader of a national militia with millions of members. However, the threat of a declaration of martial law from Hindenburg, the only person in Germany with the authority to potentially depose the Nazi regime, put Hitler under pressure to act. He left Neudeck with the intention of both destroying Röhm and settling scores with old enemies. Both Himmler and Göring welcomed Hitler's decision, since both had much to gain by Röhm's downfall – the independence of the SS for Himmler, and the removal of a rival for the future command of the army for Göring.

In preparation for the purge both Himmler and Heydrich, chief of the SS Security Service, assembled a dossier of manufactured evidence to suggest that Röhm had been paid twelve million marks (EUR 48.3 million as of 2012) by France to overthrow Hitler. Leading officers in the SS were shown falsified evidence on June 24 that Röhm planned to use the SA to launch a plot against the government (Röhm-Putsch). Göring, Himmler, Heydrich, and Victor Lutze (at Hitler's direction) drew up lists of people in and outside the SA to be killed. One of the men Göring recruited to assist him was Willi Lehmann, a Gestapo official and NKVD spy. On June 25, General Werner von Fritsch placed the Reichswehr on the highest level of alert. On June 27, Hitler moved to secure the army's cooperation. Blomberg and General Walther von Reichenau, the army's liaison to the party, gave it to him by expelling Röhm from the German Officers' League. On June 29, a signed article in Völkischer Beobachter by Blomberg appeared in which Blomberg stated with great fervour that the Reichswehr stood behind Hitler. Hitler felt confident enough in his position to attend a wedding reception in Essen, although he appeared somewhat agitated and preoccupied. From there he called Röhm's adjutant at Bad Wiessee and ordered SA leaders to meet with him on June 30.

At Bad Wiessee, Hitler personally placed Röhm and other high-ranking SA leaders under arrest. According to Erich Kempka, one of the men present during the raid, Hitler turned Röhm over to "two detectives holding pistols with the safety catch removed", and the SS found Breslau SA leader Edmund Heines in bed with an unidentified eighteen-year-old male SA senior troop leader. Goebbels emphasised the latter in subsequent propaganda justifying the purge as a crackdown on moral turpitude. Both Heines and his partner were shot on the spot in the hotel grounds on the personal order of Hitler. Meanwhile, the SS arrested a number of SA leaders as they departed their train for a planned meeting with Röhm.

The fact that no plot by Röhm to overthrow the regime ever existed did not prevent Hitler from denouncing the leadership of the SA Arriving back at party headquarters in Munich, Hitler addressed the assembled crowd. Consumed with rage, Hitler denounced "the worst treachery in world history". Hitler told the crowd that "undisciplined and disobedient characters and asocial or diseased elements" would be annihilated. The crowd, which included party members and many SA members fortunate enough to escape arrest, shouted its approval. Hess, present among the assembled, even volunteered to shoot the "traitors" himself. Joseph Goebbels, who had been with Hitler at Bad Wiessee, set the final phase of the plan in motion. Upon returning to Berlin, he telephoned Göring with the codeword Kolibri to let loose the execution squads on the rest of their unsuspecting victims.

Hitler, Göring, and Himmler unleashed the Gestapo against old enemies as well. Both Kurt von Schleicher, Hitler's predecessor as chancellor, and his wife were murdered at their home. Others killed included Gregor Strasser, a former Nazi who had angered Hitler by resigning from the party in 1932, and Gustav Ritter von Kahr, the former Bavarian state commissioner who crushed the Beer Hall Putsch in 1923.^[42] Kahr's fate was especially gruesome. His body was found in a wood outside Munich; he had been hacked to death, apparently with pickaxes. The murdered included at least one accidental victim: Willi Schmid, the music critic of the Münchner Neuste Nachrichten, a Munich newspaper. The Gestapo mistook him for Ludwig Schmitt, a past supporter of Otto Strasser, the brother of Gregor.  Such unrestrained violence added to the fearsome reputation of the Gestapo, the Nazis' secret police.

Röhm's fate

Röhm was held briefly at Stadelheim Prison^[i] in Munich, while Hitler considered his fate. In the end, Hitler decided that Röhm had to die. On July 2, at Hitler's behest, Theodor Eicke, later Commandant of the Dachau concentration camp, and SS Officer Michel Lippert visited Röhm. Once inside Röhm's cell, they handed him a loaded Browning pistol and told him he had ten minutes to kill himself or they would do it for him. Röhm demurred, telling them, "If I am to be killed, let Adolf do it himself."  Having heard nothing in the allotted time, they returned to Röhm's cell to find him standing, with his bare chest puffed out in a gesture of defiance. Lippert shot him dead at point-blank range. In 1957, the German authorities tried Lippert in Munich for Röhm's murder. Until then, Lippert had been one of the few executioners of the purge to evade trial. Lippert was sentenced to 18 months in prison.

In this hour I was responsible for the fate of the German people, and thereby I became the supreme judge of the German people. I gave the order to shoot the ringleaders in this treason, and I further gave the order to cauterise down to the raw flesh the ulcers of this poisoning of the wells in our domestic life. Let the nation know that its existence—which depends on its internal order and security—cannot be threatened with impunity by anyone! And let it be known for all time to come that if anyone raises his hand to strike the State, then certain death is his lot.

Concerned with presenting the massacre as legally sanctioned, Hitler had the cabinet approve a measure on July 3 that declared, "The measures taken on June 30, July 1 and 2 to suppress treasonous assaults are legal as acts of self-defence by the State." Reich Justice Minister Franz Gürtner, a conservative who had been Bavarian Justice Minister in the years of the Weimar Republic, demonstrated his loyalty to the new regime by drafting the statute, which added a legal veneer to the purge.Signed into law by Hitler, Gürtner, and Minister of the Interior Wilhelm Frick, the "Law Regarding Measures of State Self-Defence" retroactively legalised the murders committed during the purge. Germany's legal establishment further capitulated to the regime when the country's leading legal scholar, Carl Schmitt, wrote an article defending Hitler's July 13 speech. It was named "The Führer Upholds the Law".

Reaction

Almost unanimously, the army applauded the Night of the Long Knives, even though the generals Kurt von Schleicher and Ferdinand von Bredow were among the victims. The ailing President Hindenburg, Germany's highly revered military hero, sent a telegram expressing his "profoundly felt gratitude" and he congratulated Hitler for "nipping treason in the bud". General von Reichenau went so far as to publicly give credence to the lie that Schleicher had been plotting to overthrow the government. In his speech to the Reichstag on July 13 justifying his actions, Hitler denounced Schleicher for conspiring with Ernst Röhm to overthrow the government, who Hitler alleged were both traitors working in the pay of France. Since Schleicher was a good friend of the French Ambassador André François-Poncet, and because of his reputation for intrigue, the claim that Schleicher was working for France had enough certain surface plausibility for most Germans to accept it, though it was not in fact true.  The falsity of Hitler's claims could be seen in that François-Poncet was not declared persona non grata as normally would happened if an Ambassador were caught being involved in a coup plot against his host government. The army's support for the purge, however, would have far-reaching consequences for the institution. The humbling of the SA ended the threat it had posed to the army but, by standing by Hitler during the purge, the army bound itself more tightly to the Nazi regime. One retired captain, Erwin Planck, seemed to realise this: "if you look on without lifting a finger," he said to his friend, General Werner von Fritsch, "you will meet the same fate sooner or later." Another rare exception was Field Marshal August von Mackensen, who spoke about the murders of Schleicher and Bredow at the annual General Staff Society meeting in February 1935 after they had been rehabilitated by Hitler in early January 1935.

Rumours about the Night of the Long Knives rapidly spread. Although many Germans approached the official news of the events as described by Joseph Goebbels with a great deal of skepticism, many others took the regime at its word, and believed that Hitler had saved Germany from a descent into chaos.^[k] Luise Solmitz, a Hamburg schoolteacher, echoed the sentiments of many Germans when she cited Hitler's "personal courage, decisiveness and effectiveness" in her private diary. She even compared him to Frederick the Great, the 18th-century King of Prussia.^[2] Others were appalled at the scale of the executions and at the relative complacency of many of their fellow Germans. "A very calm and easy going mailman," the diarist Victor Klemperer wrote, "who is not at all National Socialist, said, 'Well, he simply sentenced them.'" It did not escape Klemperer's notice that many of the victims had played a role in bringing Hitler to power. "A chancellor", he wrote, "sentences and shoots members of his own private army!" The extent of the massacre and the relative ubiquity of the Gestapo, however, meant that those who disapproved of the purge generally kept quiet about it. Among the few exceptions were General Kurt von Hammerstein-Equord and Field Marshal August von Mackensen, who started a campaign to have Schleicher rehabilitated by Hitler. Hammerstein, who was a close friend of Schleicher, had been much offended at Schleicher's funeral when the SS refused to allow him to attend the service and confiscated the wreaths that the mourners had brought. Besides working for the rehabilitation of Schleicher and Bredow, Hammerstein and Mackensen sent a memo to Hindenburg on July 18 setting out in considerable detail the circumstances of the murders of the two generals and noted that Papen had barely escaped. The memo went on to demand that Hindenburg punish those responsible, and criticized Blomberg for his outspoken support of the murders of Schleicher and Bredow. Finally, Hammerstein and Mackensen asked that Hindenburg reorganize the government by firing Baron Konstantin von Neurath, Robert Ley, Hermann Göring, Werner von Blomberg, Joseph Goebbels and Richard Walther Darré from the Cabinet. Instead, the memo asked that Hindenburg create a directorate to rule Germany comprising Hitler as Chancellor, General Werner von Fritsch as Vice-Chancellor, Hammerstein as Minister of Defense and Rudolf Nadolny as Foreign Minister. The request that Neurath be replaced by Nadolny, the former Ambassador to Moscow who had resigned earlier that year in protest against Hitler's anti-Soviet foreign policy, indicated that Hammerstein and Mackensen wanted a return to the "distant friendliness" towards the Soviet Union that existed until 1933.  Mackensen and Hammerstein ended their memo with:

"Excellency, the gravity of the moment has compelled us to appeal to you as our Supreme Commander. The destiny of our country is at stake. Your Excellency has thrice before saved Germany from foundering, at Tannenberg, at the end of the War and at the moment of your election as Reich President. Excellency, save Germany for the fourth time! The undersigned Generals and senior officers swear to preserve to the last breath their loyalty to you and the Fatherland".

Hindenburg never responded to the memo, though it remains unclear whether he even saw it as Otto Meißner, who decided that his future was aligned with the Nazis, may not have passed it along.^[58] It is noteworthy that even those officers who were most offended by the killings like Hammerstein and Mackensen did not blame Hitler for the purge, whom they wanted to see continue as Chancellor, and at most wanted a reorganization of the Cabinet to remove some of Hitler's more radical followers.

In late 1934-early 1935, Werner von Fritsch and Werner von Blomberg, who had been shamed into joining Hammerstein and Mackensen's rehabilitation campaign, successfully pressured Hitler into rehabilitating Generals von Schleicher and von Bredow.^[60] Fritsch and Blomberg suddenly now claimed at the end of 1934 that as army officers they could not stand the exceedingly violent press attacks on Schleicher and Bredow that had been going on since July, which portrayed them as the vilest traitors, working against the Fatherland in the pay of France. In a speech given on January 3, 1935 at the Berlin State Opera, Hitler stated that Schleicher and Bredow had been shot "in error" on the basis of false information, and that their names were to be restored to the honor rolls of their regiments at once. Hitler's speech was not reported in the German press, but the army was appeased by the speech. However, despite the rehabilitation of the two murdered officers, the Nazis continued in private to accuse Schleicher of high treason. During a trip to Warsaw in January 1935, Göring told Jan Szembek that Schleicher had urged Hitler in January 1933 to reach an understanding with France and the Soviet Union, and partition Poland with the latter, and Hitler had Schleicher killed out of disgust with the alleged advice. During a meeting with Polish Ambassador Józef Lipski on May 22, 1935, Hitler told Lipski that Schleicher was "rightfully murdered, if only because he had sought to maintain the Rapallo Treaty".  The statements that Schleicher had been killed because he wanted to partition Poland with the Soviet Union were later published in the Polish White Book of 1939, which was a collection of diplomatic documents detailing German-Polish relations up to the outbreak of the war.

Hitler named Victor Lutze to replace Röhm as head of the SA. Hitler ordered him, as one prominent historian described it, to put an end to "homosexuality, debauchery, drunkenness, and high living" in the SA. Hitler expressly told him to stop SA funds from being spent on limousines and banquets, which he considered evidence of SA extravagance. A weak man, Lutze did little to assert the SA's independence in the coming years, and the SA lost its power in Germany. The regime had all of the decorative SA daggers ground to remove the name of Röhm from the blade, which was replaced with the words "Alles für Deutschland" (Everything for Germany). Membership in the organisation plummeted from 2.9 million in August 1934 to 1.2 million in April 1938.

The Night of the Long Knives represented a triumph for Hitler, and a turning point for the German government. It established Hitler as "the supreme judge of the German people", as he put it in his July 13 speech to the Reichstag. Later, in April 1942, Hitler would formally adopt this title, thus placing himself de jure as well as de facto above the reach of the law. Centuries of jurisprudence proscribing extra-judicial killings were swept aside. Despite some initial efforts by local prosecutors to take legal action against those who carried out the murders, which the regime rapidly quashed, it appeared that no law would constrain Hitler in his use of power. The Night of the Long Knives also sent a clear message to the public that even the most prominent Germans were not immune from arrest or even summary execution should the Nazi regime perceive them as a threat. In this manner, the purge established a pattern of violence that would characterise the Nazi regime: the use of force to establish an empire.
