Polish Enigma Doubles
A Polish Enigma "double" was a machine produced by the Polish Cipher Bureau that replicated the German Enigma rotor cipher machine. The Enigma double was one result of Marian Rejewski's remarkable achievement of determining the wiring of the Enigma's rotors and reflectors. First double The Polish Cipher Bureau recognized that the Germans were using a new cipher. The Germans had mistakenly shipped a cipher machine to Poland; their attempts to recover a shipment raised the suspicions of Polish customs, and the Polish Cipher Bureau learned that the Germans were using an Enigma machine. The Bureau purchased a commercial Enigma machine, and it attempted but failed to break the cipher. In December 1932, the Polish Cipher Bureau tasked Marian Rejewski with breaking the Enigma cipher machine. A French spy had obtained some material about the Enigma, and the French had provided the material to the Polish Cipher Bureau. By that time, the commercial Enigma had been extended to use a ...

French Army
The French Army, officially known as the Land Army (french: Armée de Terre, ), is the land-based and largest component of the French Armed Forces. It is responsible to the Government of France, along with the other components of the Armed Forces. The current Chief of Staff of the French Army (CEMAT) is General , a direct subordinate of the Chief of the Defence Staff (CEMA). General Schill is also responsible to the Ministry of the Armed Forces for organization, preparation, use of forces, as well as planning and programming, equipment and Army future acquisitions.

Cipher Bureau (Poland)
The Cipher Bureau, in Polish: ''Biuro Szyfrów'' (), was the interwar Polish General Staff's Second Department's unit charged with SIGINT and both cryptography (the ''use'' of ciphers and codes) and cryptanalysis (the ''study'' of ciphers and codes, for the purpose of "breaking" them). The precursor of the agency that would become the Cipher Bureau was created in May 1919, during the Polish-Soviet War (1919–21), and played a vital role in securing Poland's survival and victory in that war. In mid-1931, the Cipher Bureau was formed by the merger of pre-existing agencies. In December 1932, the Bureau began breaking Germany's Enigma ciphers. Over the next seven years, Polish cryptologists overcame the growing structural and operating complexities of the plugboard-equipped Enigma. The Bureau also broke Soviet cryptography. Five weeks before the outbreak of World War II, on 25 July 1939, in Warsaw, the Polish Cipher Bureau revealed its Enigma-decryption techniques and equipment t ...

Saxon Palace
The Saxons ( la, Saxones, german: Sachsen, ang, Seaxan, osx, Sahson, nds, Sassen, nl, Saksen) were a group of Germanic * * * * peoples whose name was given in the early Middle Ages to a large country (Old Saxony, la, Saxonia) near the North Sea coast of northern Germania, in what is now Germany. In the late Roman Empire, the name was used to refer to Germanic coastal raiders, and as a name similar to the later "Viking". Their origins are believed to be in or near the German North Sea coast where they appear later, in Carolingian times. In Merovingian times, continental Saxons had been associated with the activity and settlements on the coast of what later became Normandy. Their precise origins are uncertain, and they are sometimes described as fighting inland, coming into conflict with the Franks and Thuringians. There is possibly a single classical reference to a smaller homeland of an early Saxon tribe, but its interpretation is disputed. According to this proposal, the S ...

Zone Libre
The ''zone libre'' (, ''free zone'') was a partition of the French metropolitan territory during World War II, established at the Second Armistice at Compiègne on 22 June 1940. It lay to the south of the demarcation line and was administered by the French government of Marshal Philippe Pétain based in Vichy, in a relatively unrestricted fashion. To the north lay the ''zone occupée'' (" occupied zone") in which the powers of Vichy France were severely limited. In November 1942, the ''zone libre'' was invaded by the German and Italian armies in ''Case Anton'', as a response to Operation Torch, the Allied landings in North Africa. Thenceforth, the ''zone libre'' and ''zone occupée'' were renamed the ''zone sud'' (southern zone) and ''zone nord'' (northern zone) respectively. From then on both were under German military administration. Origins of the ''zone libre'' On 22 June 1940, after the Battle of France, Marshal Wilhelm Keitel, representing Nazi Germany, and General Char ...

Gustave Bertrand
Gustave Bertrand (1896–1976) was a French military intelligence officer who made a vital contribution to the decryption, by Poland's Cipher Bureau, of German Enigma ciphers, beginning in December 1932. This achievement would in turn lead to Britain's celebrated World War II Ultra operation. Life Bertrand joined the French military as a private in 1914 and was wounded in 1915 at the Dardanelles. From 1926, he worked in radio intelligence. In the 1920s, French radio intelligence was decentralized. Decryption of foreign, chiefly German and Italian, ciphers and codes was the responsibility of a General Staff cryptology department, while radio monitoring was conducted by the intelligence service, ''Service de Renseignement'' or ''S.R.'' At the end of 1930, decryption was turned over to the ''S.R.'', which created a Section ''D'' (for ''Decryptement''), of which Bertrand became chief. He later took over all of French radio intelligence. Bertrand's intelligence associates had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intelligence Officer
An intelligence officer is a person employed by an organization to collect, compile or analyze information (known as intelligence) which is of use to that organization. The word of ''officer'' is a working title, not a rank, used in the same way a "police officer" can also be a sergeant, or in the military, in which non-commissioned personnel may serve as intelligence officers. Organizations which employ intelligence officers include armed forces, police, and customs agencies. Sources of intelligence Intelligence officers make use of a variety of sources of information, including ; Communications intelligence (COMINT): Eavesdropping and interception of communications (e.g., by wiretapping) including signals intelligence (SIGINT) and electronic intelligence (ELINT). ; Financial intelligence (FININT): The gathering of information about the financial affairs of entities of interest. ; Human intelligence (HUMINT): Derived from covert human intelligence sources ( Covert Human Intellige ...

Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

PC Bruno
''PC Bruno'' was a Polish–French–Spanish signals–intelligence station near Paris during World War II, from October 1939 until June 1940. Its function was decryption of cipher messages, most notably German messages enciphered on the Enigma machine. ''PC Bruno'' worked in close cooperation with Britain's decryption center at Bletchley Park. History In the early 1930s, French military intelligence acquired operation manuals and sample messages for the German Enigma cipher machine. French intelligence officer Captain Gustave Bertrand supplied this material to Poland's ''Biuro Szyfrów'' ("Cipher Bureau"), which used it as part of their successful effort to break Enigma. In July 1939 the ''Biuro Szyfrów'' gave French and British intelligence all their results. Both countries were expanding their decryption efforts in anticipation of war, and this continued after the war started in September 1939. When Poland was overrun by Germany and the Soviet Union, the key staff of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
