Polish Enigma Double
A Polish Enigma "double" was a machine produced by the Polish Biuro Szyfrów that replicated the German Enigma machine. The Enigma double was one result of Marian Rejewski's remarkable achievement of determining the wirings of the Enigma's rotors and reflectors. First Polish double The Polish Cipher Bureau realized that the Germans were using a new cipher. The Germans had mistakenly shipped a cipher machine to Poland; their attempts to recover the shipment raised the suspicions of Polish customs, and the Cipher Bureau learned that the Germans were using Enigma machines. The Bureau purchased a commercial Enigma and attempted, but failed, to break the cipher. In December 1932 the Cipher Bureau tasked Marian Rejewski with reconstructing the Enigma machine. A French spy had obtained some material about the Enigma, and the French had provided the material to the Polish Cipher Bureau. By then, for the purposes of the German military, the original commercial Enigma had been equipped ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

French Army
The French Army, officially known as the Land Army (, , ), is the principal Army, land warfare force of France, and the largest component of the French Armed Forces; it is responsible to the Government of France, alongside the French Navy, French Air and Space Force, and the National Gendarmerie. The Army is commanded by the Chief of Staff of the French Army (CEMAT), who is subordinate of the Chief of the Defence Staff (France), Chief of the Defence Staff (CEMA), who commands active service Army units and in turn is responsible to the President of France. CEMAT is also directly responsible to the Ministry of Armed Forces (France), Ministry of the Armed Forces for administration, preparation, and equipment. The French Army, following the French Revolution, has generally been composed of a mixed force of conscripts and professional volunteers. It is now considered a professional force, since the French Parliament suspended the Conscription in France, conscription of soldiers. Acc ...

Cipher Bureau (Poland)
The Cipher Bureau ( 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 (1919–1921), 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 Saxon Palace () in Warsaw, Poland, was a historic architectural landmark located on Piłsudski Square in the heart of the Polish capital. Originally built in the 17th century as a noble residence, it was later expanded and transformed into a royal palace under the Saxon House of Wettin in the 18th century. The building underwent several modifications over the centuries, most notably in the 19th century when it was redesigned in the neoclassicalstyle with a distinctive colonnade. The palace played a significant role in Polish history, serving as a military and government headquarters, including housing the General Staff of the Polish Army in the interwar period. It was also the site where Polish cryptologists first broke the German Enigma Cipher in 1932. Destroyed by the Germans during the Second World War, only a small section of its colonnade survived, which now houses the Tomb of the Unknown Soldier. Plans for the palace’s reconstruction have been discussed since the pos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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 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, Wilhelm Keitel, representing Nazi Germany, and Charles Huntziger, represen ...

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] [Amazon] |
Intelligence Officer
An intelligence officer is a member of the intelligence field 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 ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
