Ultra Records Albums
adopted by United Kingdom, British military intelligence in June 1941 for wartime signals intelligence obtained by breaking high-level encrypted enemy radio and teleprinter communications at the Government Communications Headquarters#Government Code and Cypher School (GC&CS), Government Code and Cypher School (GC&CS) at Bletchley Park. ''Ultra'' eventually became the standard designation among the western Allies of World War II, Allies for all such intelligence. The name arose because the intelligence obtained was considered more important than that designated by the highest British Classified information, security classification then used (''Most Secret'') and so was regarded as being ''Ultra Secret''. Several other cryptonyms had been used for such intelligence. The code name ''Boniface'' was used as a cover name for ''Ultra''. In order to ensure that the successful code-breaking did not become apparent to the Germans, British intelligence created a fictional MI6 master spy, ...

Nazi Germany
Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit. "National Socialist Germany") (officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945) was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a dictatorship. Under Hitler's rule, Germany quickly became a totalitarian state where nearly all aspects of life were controlled by the government. The Third Reich, meaning "Third Realm" or "Third Empire", alluded to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918).

Historiography Of World War II
The historiography of World War II is the study of how historians portray the causes, conduct, and outcomes of World War II. There are different perspectives on the causes of the war; the three most prominent are the Orthodox from the 1950s, Revisionist from the 1970s, and Post-Revisionism which offers the most contemporary perspective. The orthodox perspective arose during the aftermath of the war. The main historian noted for this perspective is Hugh Trevor-Roper. Orthodox historians argue that Hitler was a master planner who intentionally started World War II due to his strong beliefs on fascism, expansionism, and the supremacy of the German state. Revisionist historians argue that it was an ordinary war by world standards and that Hitler was an opportunist of the sort who commonly appears in world history; he merely took advantage of the opportunities given to him. This viewpoint became popular in the 1970s, especially in the revisionism of A. J. P. Taylor. Orthodox historians ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atomic Bomb
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been deployed ...

Counterfactual History
Counterfactual history (also virtual history) is a form of historiography that attempts to answer the '' What if?'' questions that arise from counterfactual conditions. As a method of intellectual enquiry, counterfactual history explores history and historical incidents by extrapolating a timeline in which key historical events either did not occur or had an outcome different from the actual historical outcome. Counterfactual history seeks by "conjecturing on what did not happen, or what might have happened, in order to understand what did happen." It has produced a literary genre which is variously called alternate history, speculative history, allohistory, and hypothetical history. Development An early book of counterfactual histories is ''If It Had Happened Otherwise'' (1931) which features "If Lee Had Not Won the Battle at Gettysburg", by Winston Churchill, about a fictional Confederate victory at the Battle of Gettysburg (1863). As a text of counterfactual histories writte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

JN-25
The vulnerability of Japanese naval codes and ciphers was crucial to the conduct of World War II, and had an important influence on foreign relations between Japan and the west in the years leading up to the war as well. Every Japanese code was eventually broken, and the intelligence gathered made possible such operations as the victorious American ambush of the Japanese Navy at Midway in 1942 (by breaking code JN-25b) and the shooting down of Japanese admiral Isoroku Yamamoto a year later in Operation Vengeance. The Imperial Japanese Navy (IJN) used many codes and ciphers. All of these cryptosystems were known differently by different organizations; the names listed below are those given by Western cryptanalytic operations. Red code The Red Book code was an IJN code book system used in World War I and after. It was called "Red Book" because the American photographs made of it were bound in red covers.Greg Goebel"US Codebreakers In The Shadow Of War" 2018. It should not be confu ...
