Allgemeine SS |
Sicherheitsdienst (German: [ˈzɪçɐhaɪtsˌdiːnst], Security Service), full title Sicherheitsdienst des Reichsführers-SS (English: Security Service of the Reichsführer-SS), or SD, was the intelligence agency of the SS and the Nazi Party in Nazi Germany. The organization was the first Nazi Party intelligence organization to be established and was considered a sister organization with the Gestapo, which the SS had infiltrated heavily after 1934. Between 1933 and 1939, the SD was administered as an independent SS office, after which it was transferred to the authority of the Reich Main Security Office (Reichssicherheitshauptamt; RSHA), as one of its seven departments/offices. Its first director, Reinhard Heydrich, intended for the SD to bring every single individual within the Third Reich's reach under "continuous supervision."
Following Germany's defeat in World War II, the SD was declared a criminal organisation at the Nuremberg Trials, along with the rest of Heydrich's RSHA (including the Gestapo) both individually and as branches of the SS in the collective. Heydrich's successor, Ernst Kaltenbrunner, was convicted of war crimes and crimes against humanity at the Nuremberg trials, sentenced to death and hanged in 1946.
The SD was one of the oldest security organizations of the SS and was first formed in 1931 as the Ic-Dienst, operating out of a single apartment and reporting directly to Heinrich Himmler. Himmler appointed a former naval officer, Reinhard Heydrich, to organise the small agency. The office was renamed Sicherheitsdienst (SD) in the summer of 1932. The SD became more powerful after the Nazis took control of Germany and the SS started infiltrating all leading positions of the security apparatus of the Reich. Even before Hitler came to power, the SD was a veritable "watchdog" over the SS and members of the Nazi Party and played a critical role in consolidating political police powers into the hands of Himmler and Heydrich.
Growth of SD and SS power
Once Hitler was appointed Chancellor by German President Paul von Hindenburg, he quickly made efforts to manipulate the aging president. On 28 February 1933, Hitler convinced Hindenburg to declare a state of emergency which suspended all civil liberties throughout Germany, due at least in part to the Reichstag fire the night before, assuring Hindenburg throughout that he was attempting to stabilize the tumultuous political scene in Germany by taking a "defensive measure against Communist acts of violence endangering the state." Wasting no time, Himmler set the SD in motion as they began creating an extensive card index of the Nazi regime's political opponents, arresting labor organizers, socialists, Jewish leaders, journalists, and communists in the process, sending them to their new prison facility near Munich, Dachau. Himmler's SS and SD made their presence felt at once by helping rid the regime of its known political enemies and its perceived ones, as well. As far as Heydrich and Himmler were concerned, the SD left their mission somewhat vaguely defined so as to "remain an instrument for all eventualities." One of those eventualities would soon arise.
For a while, the SS was in ‘competition’ with the Sturmabteilung (SA) for influence within Germany. Himmler distrusted the SA and came to deplore the ‘rabble-rousing’ brownshirts (despite once having been a member) and what they considered to be the indecent sexual deviants amid its leadership. At least one pretext to secure additional influence for Himmler's SS and Heydrich's SD in "protecting" Hitler and securing his absolute trust in their intelligence collection abilities involved thwarting a plot from Ernst Roehm's SA using subversive means.
On 20 April 1934 Hermann Göring handed over control of the Geheime Staatspolizei (Gestapo) to Himmler. Heydrich, named chief of the Gestapo by Himmler on 22 April 1934, also continued as head of the SD. These events further extended Himmler’s control of the security mechanism of the Reich, which by proxy also strengthened the surveillance power of Heydrich’s SD, as both entities methodically infiltrated every police agency in Germany. Thereafter, the SD was made the sole "Party information service" on 9 June 1934.
Under pressure from the Reichswehr (German armed forces) leadership, whose members viewed the enormous armed forces of the SA as an existential threat and with the collusion of Göring, Joseph Goebbels, the Gestapo and SD, Hitler was led to believe that Roehm’s SA posed a serious conspiratorial threat requiring a drastic and immediate solution. For its part, the SD provided fictitious information that there was an assassination plot on Hitler’s life and that an SA putsch to assume power was imminent since they were allegedly amassing weapons. Additionally, reports were coming in to the SD and Gestapo that the vulgarity of the SA's behavior was damaging the party and was even making antisemitism less palatable. In what became known as the Night of the Long Knives, the SS took one of its most decisive steps in eliminating its competition for command of security within the Third Reich and established itself firmly in the Nazi hierarchy, making the SS and its intelligence organ, the SD, responsible only to the Führer. Moreover, the brutal crushing of the SA and its leadership sent a clear message to everyone that opposition to Hitler’s regime could be deadly. In many ways, it struck fear across the Nazi leadership and a tangible concern about the reach and influence of Himmler’s intelligence collection and policing powers, since not only had the SA’s chief been murdered, but numerous party functionaries and "opponents" had been eliminated in the action based on an extensive list which Hitler only saw after the event.
The SD and Austria
During the autumn of 1937, Hitler secured Mussolini’s support to annex Austria (Mussolini was originally apprehensive of the Nazi takeover of Austria) and informed his generals of his intentions to invade both Austria and Czechoslovakia. Getting Mussolini to approve political intrigue against Austria was a major accomplishment as the Italian leader had expressed great concern previously in the wake of an Austrian SS unit’s attempt to stage a coup not more than three weeks after the Röhm affair, an episode that embarrassed the SS, enraged Hitler, and which ended in the assassination of Austrian Chancellor Engelbert Dollfuss. Nonetheless, to facilitate the incorporation of Austria into the greater Reich, the SD and Gestapo went to work arresting people right away using lists compiled by Heydrich. Heydrich’s SD and Austrian SS members received financing from Berlin to harass Austrian Chancellor von Schuschnigg’s government all throughout 1937. One section of the SD that was nothing more than a front for subversive activities against Austria ironically promoted “German-Austrian peace.”
Throughout the events leading to the Anschluß and even after the Nazis marched into Austria, Heydrich - convinced that only his SD could pull off a peaceful union between the two German-speaking nations - organized demonstrations, conducted clandestine operations, ordered terror attacks, distributed propaganda materials, encouraged the intimidation of opponents, and had his SS and SD personnel round-up prominent anti-Nazis, most of whom ended up in Mauthausen concentration camp. Through the coordinated efforts of the SiPo and Heydrich's SD during the first days of the Anschluß, all forms of possible political, military and economic resistance within Austria were effectively eliminated. Once the annexation was official, the Austrian police was immediately subordinated to Heydrich’s SD, SS and the Gestapo. Machinations by the SD, the Gestapo, and the SS helped to bring Austria fully into Hitler's grasp and on 13 March 1938, he signed into law the union with Austria as tears streamed down his face.
“Case Green” and the Sudetenland
Concomitant to their machinations against Austria, the SD was also involved in subversive activities throughout Czechoslovakia. Focusing on the Sudetenland with its 3 million ethnic Germans and the disharmony there which the Czech government could not seem to remedy, Hitler set Heydrich’s SD in motion there in what came to be known as "Case Green". This SD intelligence operation was akin to their earlier efforts in Austria; however, unlike Austria, the Czechs fielded their own Secret Service against which, Heydrich had to contend. Once "Case Green" (which included military invasion to smash Czechoslovakia) began (as early as 1937), Heydrich’s SD spies began covertly gathering (even going so far as having SD agents use their spouses and children in the cover scheme) every conceivable type of intelligence data possible using a myriad of cameras and photographic equipment, focusing their efforts on important strategic locations like government buildings, police stations, postal services, public utilities, logistical routes, and above all, airfields. The SD activities in this regard can only be described as military espionage.
Hitler worked out a sophisticated plan to acquire the Sudetenland, which included manipulating Slovak nationalists to vie for independence and the suppression of this movement by the Czech government. Under directions from Heydrich, SD operative Alfred Naujocks was once again activated to engage in sabotage activities designed to incite a response from the Slovakians and the Czechs, a mission that ultimately failed. In June 1938, a directive from the head SD office indicated that Hitler issued an order at Jueterbog to his generals to prepare for the invasion of Czechoslovakia.
To hasten a presumed heavy response from the French, British, and Czechs, Hitler then upped the stakes and claimed that the Czechs were slaughtering Sudeten Germans, demanding the unconditional and prompt cession of the Sudetenland to Germany in order to secure the safety of endangered ethnic Germans. It was around this time that early plots from select members of the German General Staff to rid themselves of Hitler arose. How much the SD knew about schemes to subvert Hitler remains unknown.
Eventually a diplomatic showdown pitting Hitler against the governments of Czechoslovakia, Great Britain, and France, whose tepid reaction to Austria precipitated this crisis to some degree, ensued. The Sudetenland Crisis came to an end when Neville Chamberlain and Hitler signed the Munich Agreement on 29 September 1938, effectively ceding the Sudetenland to Nazi Germany. Involvement in international affairs by the SD certainly did not end there and they remained active in foreign operations to such a degree that the head of the Foreign Ministry office, Joachim von Ribbentrop, complained of their meddling, since Hitler would apparently make decisions based on SD reports without consulting him. Following the Sudetenland Crisis, the SD then took part in operations against Poland.
Intrigue against Poland
Aside from their participation in diminishing the power of the SA and their scheme to kill Ernst Roehm, the SD took part in international intrigue, first by activities in Austria, again in Czechoslovakia, and then by helping provoke the 'reactive' war against Poland. Code-named "Operation Himmler" and part of Hitler's plan to justify an attack upon Poland, the SD's clandestine activity for this mission included faking a Polish attack against 'innocent Germans' at a German radio station in Gleiwitz. Using concentration camp inmates condemned to die, the SD fitted them with Polish Army uniforms Heinz Jost had acquired from Admiral Wilhelm Canaris' Abwehr (military intelligence). Leading this mission and personally selected by Heydrich was SS veteran Alfred Naujocks, who later reported during a War Criminal proceeding that he brought a Polish-speaking German along so he could broadcast a message in Polish from the German radio station 'under siege' that it was time for an all out confrontation between Germans and Poles. To add documented proof of this attack, the SD operatives placed the fictitious Polish troops (killed by lethal injection, then shot for appearance) around the 'attacked' radio station with the intention of taking members of the press to the site of the incident. Immediately in the wake of the staged incidents on 1 September 1939, Hitler proclaimed from the Reichstag in a famous radio address that German soldiers had been 'returning' fire since 0545 in the morning, setting the Second World War in Europe into motion.
Tasks and general structure
The SD was tasked with the detection of actual or potential enemies of the Nazi leadership and the neutralization of this opposition as the action against the SA demonstrated. To fulfill this task, the SD created an organization of agents and informants throughout the Reich and later throughout the occupied territories, all part of the development of an extensive SS state and a totalitarian regime without parallel. The organization consisted of a few hundred full-time agents and several thousand informants. Historian George C. Browder writes that SD regiments were comparable to SS regiments, in that:
- "SD districts (Bezirke) emerged covering several Party circuits (Kreis) or an entire district (Gau). Below this level, SD sub-districts (Unterbezirke) slowly developed. They were originally to cover a single Kreis, and, in turn, to be composed of wards (Revier), but such an ambitious network never emerged. Eventually, the SD-sub-districts acquired the simple designation of 'outposts' (Aussenstellen) as the lowest level-office in the field structure."
The SD was mainly the information-gathering agency, and the Gestapo, and to a degree the Kriminalpolizei (Kripo), was the executive agency of the political police system. Both the SD and the Gestapo were departments under Heydrich's control which answered to Himmler as both Chief of the German Police and Reichsfuhrer-SS, but the Kripo kept a level of independence since its structure was longer-established.
Part and parcel to intelligence operations, the SD carefully tracked foreign opinion and criticism of Nazi policies, censoring when necessary and likewise publishing hostile political cartoons in the SS weekly magazine, Das Schwarze Korps. An additional task assigned to the SD and the Gestapo was keeping tabs on the morale of the German population at large which meant they were charged to "carefully supervise the political health of the German ethnic body" and once any symptoms of "disease and germs" appeared, it was their job to "remove them by every appropriate means." Regular reports - ranging from opinion polls, press dispatches, and information bulletins were established. These were monitored and reviewed by then head of the Inland-SD, Otto Ohlendorf (responsible for intelligence and security within Germany) and the former Heidelberg professor and SD member Reinhard Höhn, all designed to control and assess the "life domain" or Lebensgebiet of the German population. Gathered information was then distributed by the SD through secret internal political reports entitled Meldungen aus dem Reich (reports from the Reich) to the upper echelons of the Nazi Party, enabling Hitler's regime to evaluate the general morale and attitude of the German people so it could be timely manipulated by the Nazi propaganda machine. When the Nuremberg Laws were passed in 1935, the SD reported that the measures against the Jews were well received by the German populace.
In 1936, the police were divided into the Ordnungspolizei (Orpo or Order Police) and the Sicherheitspolizei (SiPo or Security Police). The Orpo consisted mainly of the Schutzpolizei (Urban police), the Gendarmerie (Rural police) and the Gemeindepolizei (Municipal police). The SiPo was composed of the Kripo and the Gestapo. Heydrich became Chief of the SiPo and continued as Chief of the SD. Continuing escalation of antisemitic policies in the spring of 1937 from the SD organization concerned with Jewish affairs, staffed by members like Adolf Eichmann, Herbert Hagen, and Theodor Dannecker, led to an advocation for the complete removal (Entfernung) of all Jews from Germany with very little concern for where they were headed.
Due to the fact that the Gestapo and SD had parallel duties, Heydrich tried to reduce any confusion or related territorial disputes through a decree on 1 July 1937, clearly defining the SD's area of responsibility as those dealing with "learning (Wissenschaft), art, party and state, constitution and administration, foreign lands, Freemasonry and associations" whereas the "Gestapo's jurisdiction was Marxism, treason, and emigrants." Additionally, the SD was responsible for matters related to "churches and sects, pacifism, the Jews, right-wing movements", as well as "the economy, and the Press", but the SD was instructed to "avoid all matters which touched the 'state police executive powers' [staatspolizeiliche Vollzugsmaßnahmen] since these belonged to the Gestapo, as did all individual cases."
In 1938, the SD was made the intelligence organization for the State as well as for the Party, supporting the Gestapo and working with the General and Interior Administration. As such, the SD came into immediate, fierce competition with German military intelligence, the Abwehr as headed by Admiral Canaris. The competition stemmed from Heydrich and Himmler's intention to absorb the Abwehr and Admiral Canaris' view of the SD as an amateur upstart. Canaris refused to give up the autonomy that his military intelligence organ was granted. Additional problems also existed, like the racial exemption for members of the Abwehr from the Nazi Aryan screening process, and then there was competition for resources which occurred throughout the Third Reich's existence.
On 27 September 1939, the Sicherheitspolizei became a part of the RSHA under Heydrich. The operational sections of the SD became (department) Amt III and for foreign intelligence, Amt VI; the Gestapo became Amt IV and the Kripo became Amt V. Otto Ohlendorf was named the Chief of Amt III, the SD-Inland (within Germany); Heinrich Müller was named the Chief of Amt IV, the Gestapo; Arthur Nebe was named the Chief of Amt V, the Kripo; and Walter Schellenberg became Chief of Amt VI, the SD-Ausland (outside Germany). In 1944, the sections of the Abwehr were incorporated into Amt VI.
SD relationship to the Einsatzgruppen
The SD was the overarching agency under which the Einsatzgruppen der Sicherheitspolizei und des SD, also known as the Einsatzgruppen, was subordinated; this was one of the principal reasons for the later war-crimes indictment against the organization by the Allies. The Einsatzgruppen’s part in the Holocaust has been well documented. Its mobile killing units were active in the implementation of the Final Solution in the territories overrun by the Nazi war machine. This SD subsidiary worked closely with the Wehrmacht in persecuting Jews, communists, partisans, and other groups, as well. Starting with the invasion of Poland throughout the campaign in the East, the Einsatzgruppen ruthlessly killed anyone suspected of being an opponent of the regime, either real or imagined. The men of the Einsatzgruppen were recruited from the SD, Gestapo, Kripo, Orpo, and Waffen-SS.
On 31 July 1941, Göring gave written authorisation to SD Chief Heydrich to ensure the cooperation of administrative leaders of various government departments in the implementation of a Endlösung der Judenfrage (Final Solution to the Jewish question) in territories under German control. An SD headquarter's memorandum indicated that the SD was tasked to accompany military invasions so as to assist in control and pacification efforts. The memo explicitly stated:
- The SD will, where possible, follow up immediately behind the troops as they move in and, as in the Reich, will assume responsibility for the security of political life. Within the Reich, security measures are the responsibility of the Gestapo with SD cooperation. In occupied territory, measures will be under the direction of a senior SD commander; Gestapo officials will be allotted to individual Einsatzstäbe. It will be necessary to make available for special deployment a unit of Verfügungstruppe or Totenkopf [Death Head] formations.
Correspondingly, SD affiliated units, including the Einsatzgruppen followed German troops into Austria, the Sudetenland, Bohemia, Moravia, Poland, Lithuania, as well as Russia. Since their task included cooperating with military leadership and vice versa, suppression of opposition in the occupied territories was a joint venture, so any attempt to feign ignorance on the part of the military leadership loses credibility in light of the orders passed up and down their respective commands. There were territorial disputes and disagreement about how some of these policies were to be implemented.
On 20 January 1942, Heydrich chaired a meeting, now called the Wannsee Conference, to discuss the implementation of the plan. Facilities such as Chelmno, Majdanek, Sobibor, Treblinka, and Auschwitz have their origins in the planning actions undertaken by Heydrich. Heydrich remained chief of the Security Police (SiPo) and the SD (through the RSHA) until his assassination in 1942, after which Ernst Kaltenbrunner was named chief by Himmler on 30 January 1943, and remained there until the end of the war. The SD was declared a criminal organization after the war and its members were tried as war criminals at Nuremberg. Whatever their original purpose, the SD and SS were ultimately created to identify and eradicate internal enemies of the State, as well as to pacify, subjugate, and exploit conquered territories and peoples.
By 1933, the organization was known as the SS SD-Amt and, in 1934, became the official security organization of the entire Nazi Party. Consisting at first of paid agents and a few hundred unpaid informants scattered across Germany, the SD was quickly professionalized under Heydrich, who commissioned National Socialist academics and lawyers to ensure that the SS and the SD in particular, operated "within the framework of National Socialist ideology." Heydrich was given the power to select men for the SD from among any of the SS component commands since Himmler considered the organization of the SD so important. In 1939, the SD was divided into two offices, the Inland-SD and Ausland-SD, and placed under the authority of the RSHA.
The Inland-SD (Office II) was originally headed by SS-Colonel Hermann Behrends until September 1939 and it was within this organization that Adolf Eichmann began working out the details for the Final Solution of the Jewish problem. The Inland SD was responsible for intelligence and security within Germany and was divided into the following sub-offices:
- Department A (Law and Legal Structures)
- Department B (Race and Ethnic Matters)
- Department C (Cultural and Religious Matters)
- Department D (Industry and Commerce)
- Department E (High Society)
The Ausland-SD (Office III) was the civilian foreign intelligence agency of the Third Reich and was "nominally commanded by Heydrich, but his chief of staff was SS-Colonel Heinz Jost." Jost ran the department until March 1942. Jost was fired from his position as Chief of Ausland-SD which, as of September 1939, had officially become known as Amt VI (department VI) of the RSHA. Jost's place was taken by Brigadeführer Walter Schellenberg, a deputy of Heydrich. After the July 20 Plot in 1944, the Ausland-SD took over the functions of the Abwehr (military intelligence). The Ausland-SD was divided into the following sections:
- Department A (Organization and Administration)
- Department B (Espionage in the West)
- Department C (Espionage in the Soviet Union and Japan)
- Department D (Espionage in the American sphere)
- Department E (Espionage in Eastern Europe)
- Department F (Technical Matters)
Given the nature of the intelligence operations assigned to the SD, there were clear delineations between what constituted a full member (Mitglieder) of the SD and those who were considered "associates" (Mitarbeiter) with a further subset for clerical support personnel (typists, file clerks, etc.) who were connoted as V-persons (Vertrauensleute). All SD personnel, whether simply associates or full members were required to swear an oath of secrecy, had to meet all the requirements for SS membership, were assigned SD code numbers (Chiffre Nummer) and if they were "above the level of V-person" they had to carry "an SD identification card." The vast majority of early SD members were relatively young, but the officers were typically older by comparison; nevertheless, the average age of an SD member was approximately 2 years older than the average Nazi Party member. Much like the Nazi revolution in general, membership in the SS and the SD appealed more to the impressionable youth. Most SD members were Protestant by faith, had served in the military, and generally had a significant amount of education, representing "an educated elite" in the general sense - with about 14 percent of them earning doctorate degrees. Heydrich viewed the SD as spiritual-elite leaders within the SS and the "cream of the cream of the NSDAP."
According to historian George C. Browder, "SD men represented no pathological or psychically susceptible group. Few were wild or extreme Nazi fanatics. In those respects they were 'ordinary men'. Yet in most other respects, they were an extraordinary mix of men, drawn together by a unique mix of missions." Along with members of the Gestapo, SD personnel were "regarded with a mixture of fear and foreboding," and people wanted as little to do with them as possible. Belonging to the security apparatus of the Third Reich obviously had its advantages but it was also fraught with occupationally related social disadvantages as well, and if post-war descriptions of the SD by historians are any indication, membership therein implied being a part of a "ubiquitous secret society" which was "sinister" and a "messenger of terror" not just for the German population, but within the "ranks of the Nazi Party itself."
The SD and the SiPo were the main sources of officers for the security forces in occupied territories. SD-SiPo led battalions were typically placed under the command of the SS and Police Leaders, reporting directly to the RSHA in Berlin. The SD also maintained a presence at all concentration camps and supplied personnel, on an as-needed basis, to such special action troops as the Einsatzgruppen. In fact, all members of the Einsatzgruppen wore the SD sleeve diamond on their uniforms.
The SD-SiPo was the primary agency, in conjunction with the Ordnungspolizei, assigned to maintain order and security in the Jewish ghettos established by the Germans on the territory of occupied Eastern Europe. On 7 December 1941, the same day that the American naval station at Pearl Harbor was bombed by the Japanese, the first extermination camp was opened at Chelmno near Lodz by the SD and SiPo commander in occupied Poznań (Posen), then SS-Standartenführer Ernst Damzog. Damzog had personally selected the staff for the killing centre and later supervised the daily operation of the camp which was under the command of SS-Hauptsturmführer Herbert Lange. Over a span of approximately 15 months, 150,000 people were killed there.
The SD also maintained local offices in Germany's cities and larger towns. The small offices were known as SD-Unterabschnitte, and the larger offices were referred to as SD-Abschnitte. All SD offices answered to a local commander known as the Inspektor des Sicherheitspolizei und SD who, in turn, was under the dual command of the RSHA and local SS and Police Leaders.
According to the book Piercing the Reich, the SD was infiltrated in 1944 by a former Russian national who was working for the Americans. The agent's parents had fled the Russian Revolution, and he had been raised in Berlin, and then moved to Paris. He was recruited by Albert Jolis of the Office of Strategic Services (OSS) Seventh Army detachment. The mission was codenamed RUPPERT.
How extensive the SD’s knowledge was about the early plots to kill Hitler by key members of the military remains a contested subject and a veritable unknown. According to British historian John Wheeler-Bennett, “in view of the wholesale destruction of Gestapo archives it is improbable that this knowledge will ever be forthcoming. That the authorities were aware of serious 'defeatism' is certain, but it is doubtful whether they suspected anyone of outright treason.”
