Cipher Department Of The High Command Of The Wehrmacht
The Cipher Department of the High Command of the Wehrmacht (german: Amtsgruppe Wehrmachtnachrichtenverbindungen, Abteilung Chiffrierwesen) (also ''Oberkommando der Wehrmacht Chiffrierabteilung'' or ''Chiffrierabteilung of the High Command of the Wehrmacht'' or ''Chiffrierabteilung of the OKW'' or ''OKW/Chi'' or ''Chi'') was the Signal Intelligence Agency of the Supreme Command of the Armed Forces of the German Armed Forces before and during World War II. OKW/Chi, within the formal order of battle hierarchy OKW/WFsT/Ag WNV/Chi, dealt with the cryptanalysis and deciphering of enemy and neutral states' message traffic and security control of its own key processes and machinery, such as the rotor cipher machine ENIGMA machine. It was the successor to the former Chi bureau (german: Chiffrierstelle) of the Reichswehr Ministry. Short name The letter "Chi" for the ''Chiffrierabteilung'' ("cipher department") is, contrary to what one might expect, not the Greek letter Chi , nor anythin ...

Signals Intelligence
Signals intelligence (SIGINT) is intelligence-gathering by interception of ''signals'', whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). Signals intelligence is a subset of intelligence collection management. As classified and sensitive information is usually encrypted, signals intelligence in turn involves the use of cryptanalysis to decipher the messages. Traffic analysis—the study of who is signaling whom and in what quantity—is also used to integrate information again. History Origins Electronic interceptions appeared as early as 1900, during the Boer War of 1899–1902. The British Royal Navy had installed wireless sets produced by Marconi on board their ships in the late 1890s, and the British Army used some limited wireless signalling. The Boers captured some wireless sets and used them to make vital transmis ...

Heinrich Himmler
Heinrich Luitpold Himmler (; 7 October 1900 – 23 May 1945) was of the (Protection Squadron; SS), and a leading member of the Nazi Party of Germany. Himmler was one of the most powerful men in Nazi Germany and a main architect of the Holocaust. As a member of a reserve battalion during World War I, Himmler did not see active service, and did not fight. He studied agriculture in university, and joined the Nazi Party in 1923 and the SS in 1925. In 1929, he was appointed by Adolf Hitler. Over the next 16 years, he developed the SS from a 290-man battalion into a million-strong paramilitary group, and set up and controlled the Nazi concentration camps. He was known for good organisational skills and for selecting highly competent subordinates, such as Reinhard Heydrich in 1931. From 1943 onwards, he was both Chief of German Police and Minister of the Interior, overseeing all internal and external police and security forces, including the Gestapo (Secret State Police). H ...

Joachim Von Ribbentrop
Ulrich Friedrich Wilhelm Joachim von Ribbentrop (; 30 April 1893 – 16 October 1946) was a German politician and diplomat who served as Minister of Foreign Affairs of Nazi Germany from 1938 to 1945. Ribbentrop first came to Adolf Hitler's notice as a well-travelled businessman with more knowledge of the outside world than most senior Nazis and as a perceived authority on foreign affairs. He offered his house Schloss Fuschl for the secret meetings in January 1933 that resulted in Hitler's appointment as Chancellor of Germany. He became a close confidant of Hitler, to the disgust of some party members, who thought him superficial and lacking in talent. He was appointed ambassador to the Court of St James's, the royal court of the United Kingdom, in 1936 and then Foreign Minister of Germany in February 1938. Before World War II, he played a key role in brokering the Pact of Steel (an alliance with Fascist Italy) and the Molotov–Ribbentrop Pact (the Nazi–Soviet non-aggr ...

Hermann Göring
Hermann Wilhelm Göring (or Goering; ; 12 January 1893 – 15 October 1946) was a German politician, military leader and convicted war criminal. He was one of the most powerful figures in the Nazi Party, which ruled Germany from 1933 to 1945. A veteran World War I fighter pilot ace, Göring was a recipient of the ("The Blue Max"). He was the last commander of ''Jagdgeschwader'' 1 (Jasta 1), the fighter wing once led by Manfred von Richthofen. An early member of the Nazi Party, Göring was among those wounded in Adolf Hitler's failed Beer Hall Putsch in 1923. While receiving treatment for his injuries, he developed an addiction to morphine which persisted until the last year of his life. After Hitler became Chancellor of Germany in 1933, Göring was named as minister without portfolio in the new government. One of his first acts as a cabinet minister was to oversee the creation of the Gestapo, which he ceded to Heinrich Himmler in 1934. Following the establishment of th ...

Schutzstaffel
The ''Schutzstaffel'' (SS; also stylized as ''ᛋᛋ'' with Armanen runes; ; "Protection Squadron") was a major paramilitary organization under Adolf Hitler and the Nazi Party in Nazi Germany, and later throughout German-occupied Europe during World War II. It began with a small guard unit known as the ''Saal-Schutz'' ("Hall Security") made up of party volunteers to provide security for party meetings in Munich. In 1925, Heinrich Himmler joined the unit, which had by then been reformed and given its final name. Under his direction (1929–1945) it grew from a small paramilitary formation during the Weimar Republic to one of the most powerful organizations in Nazi Germany. From the time of the Nazi Party's rise to power until the regime's collapse in 1945, the SS was the foremost agency of security, surveillance, and terror within Germany and German-occupied Europe. The two main constituent groups were the '' Allgemeine SS'' (General SS) and ''Waffen-SS'' (Armed SS). The ' ...

RSHA
The Reich Security Main Office (german: Reichssicherheitshauptamt or RSHA) was an organization under Heinrich Himmler in his dual capacity as ''Chef der Deutschen Polizei'' (Chief of German Police) and ''Reichsführer-SS'', the head of the Nazi Party's ''Schutzstaffel'' (SS). The organization's stated duty was to fight all "enemies of the Reich" inside and outside the borders of Nazi Germany. Formation and development Himmler established the RSHA on 27 September 1939.

Pers Z S
The Pers Z S was the signals intelligence agency of the German Foreign Office (german: Auswärtiges Amt) before and during World War II. It consisted of two cryptologic sections. Pers Z S was the cryptanalytic section which was called ''Special Service of Z Branch of the Foreign Office Personnel Department'' (german: Sonderdienst des Referats Z in der Personalabteilung des Auswärtigen Amtes). Its mission was the solution of foreign diplomatic codes and ciphers. The other section, which was the Cryptography Section was called ''Personal Z Cipher Service of the Federal Foreign Office'' (german: Personal Z Chiffrierdienst des Auswärtigen Amtes) (abbr. Pers Z Chi). The latter section was responsible for compilation, distribution and security of Foreign Office codes and ciphers. Both were colloquially known as Pers Z S. Though similar in nature and operation to the OKW/Chi cipher bureau, it was a civilian operation as opposed to the military operation at OKW/Chi and focused primarily o ...

Abwehr
The ''Abwehr'' (German for ''resistance'' or ''defence'', but the word usually means ''counterintelligence'' in a military context; ) was the German military-intelligence service for the ''Reichswehr'' and the ''Wehrmacht'' from 1920 to 1944. Although the 1919 Treaty of Versailles prohibited the Weimar Republic from establishing an intelligence organization of their own, they formed an espionage group in 1920 within the Ministry of Defence, calling it the ''Abwehr''. The initial purpose of the ''Abwehr'' was defence against foreign espionage: an organizational role which later evolved considerably. Under General Kurt von Schleicher (prominent in running the ''Reichswehr'' from 1926 onwards) the individual military services' intelligence units were combined and, in 1929, centralized under Schleicher's ''Ministeramt'' within the Ministry of Defence, forming the foundation for the more commonly understood manifestation of the ''Abwehr''. Each ''Abwehr'' station throughout German ...
