Quebec Conference, 1943
The First Quebec Conference, codenamed "Quadrant", was a highly secret military conference held during World War II by the governments of the United Kingdom, Canada, and the United States. It took place in Quebec City on August 17–24, 1943, at both the Citadelle of Quebec, Citadelle and the Château Frontenac. The chief representatives were Winston Churchill and Franklin D. Roosevelt, hosted by the Canadian prime minister William Lyon Mackenzie King. Conference Although Churchill suggested that Mackenzie King be involved in all discussions, Roosevelt vetoed the idea due to concern that future conferences would be encumbered by all of the Allied nations demanding seats. As a result, Mackenzie King's hospitality was almost purely for ceremonial purposes. Joseph Stalin, leader of the Soviet Union, had been invited to join the conference, but he did not attend for military reasons. The Allies of World War II, Allies agreed to begin discussions for the planning of the Invasion of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Theater (warfare)
In warfare, a theater or theatre is an area in which important military events occur or are in progress. A theater can include the entirety of the airspace, land and sea area that is or that may potentially become involved in war operations. Theater of war In his book ''On War'', Carl von Clausewitz defines the term ''Kriegstheater'' (translating the older, 17th-century Latin term ''theatrum belli'') as one that: Theater of operations ''Theater of operations'' (TO) is a sub-area within a theater of war. The boundary of a TO is defined by the commander who is orchestrating or providing support for specific combat operations within the TO. Theater of operations is divided into strategic directions or military regions depending on whether it is a war or peacetime. The United States Armed Forces split into Unified Combatant Commands (regions) that are assigned to a particular theater of military operations. A strategic direction is a group of armies also known as a task (fie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guerrilla Warfare
Guerrilla warfare is a form of irregular warfare in which small groups of combatants, such as paramilitary personnel, armed civilians, or Irregular military, irregulars, use military tactics including ambushes, sabotage, Raid (military), raids, petty warfare, hit-and-run tactics, and Mobility (military), mobility, to fight a larger and less-mobile traditional military. Although the term "guerrilla warfare" was coined in the context of the Peninsular War in the 19th century, the tactical methods of guerrilla warfare have long been in use. In the 6th century BC, Sun Tzu proposed the use of guerrilla-style tactics in ''The Art of War''. The 3rd century BC Roman general Quintus Fabius Maximus Verrucosus is also credited with inventing many of the tactics of guerrilla warfare through what is today called the Fabian strategy. Guerrilla warfare has been used by various factions throughout history and is particularly associated with revolutionary movements and popular resistance agains ...

Balkans
The Balkans ( ), also known as the Balkan Peninsula, is a geographical area in southeastern Europe with various geographical and historical definitions. The region takes its name from the Balkan Mountains that stretch throughout the whole of Bulgaria. The Balkan Peninsula is bordered by the Adriatic Sea in the northwest, the Ionian Sea in the southwest, the Aegean Sea in the south, the Turkish Straits in the east, and the Black Sea in the northeast. The northern border of the peninsula is variously defined. The highest point of the Balkans is Mount Musala, , in the Rila mountain range, Bulgaria. The concept of the Balkan Peninsula was created by the German geographer August Zeune in 1808, who mistakenly considered the Balkan Mountains the dominant mountain system of Southeast Europe spanning from the Adriatic Sea to the Black Sea. The term ''Balkan Peninsula'' was a synonym for Rumelia in the 19th century, the European provinces of the Ottoman Empire. It had a ge ...

Tube Alloys
Tube Alloys was the research and development programme authorised by the United Kingdom, with participation from Canada, to develop nuclear weapons during the Second World War. Starting before the Manhattan Project in the United States, the British efforts were kept classified, and as such had to be referred to by code even within the highest circles of government. The possibility of nuclear weapons was acknowledged early in the war. At the University of Birmingham, Rudolf Peierls and Otto Robert Frisch co-wrote a memorandum explaining that a small mass of pure uranium-235 could be used to produce a chain reaction in a bomb with the power of thousands of tons of TNT. This led to the formation of the MAUD Committee, which called for an all-out effort to develop nuclear weapons. Wallace Akers, who oversaw the project, chose the deliberately misleading code name "Tube Alloys". His Tube Alloys Directorate was part of the Department of Scientific and Industrial Research. The Tube ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quebec Agreement
The Quebec Agreement was a secret agreement between the United Kingdom and the United States outlining the terms for the coordinated development of the science and engineering related to nuclear energy and specifically nuclear weapons. It was signed by Winston Churchill and Franklin D. Roosevelt on 19 August 1943, during World War II, at the First Quebec Conference in Quebec City, Quebec, Canada. The Quebec Agreement stipulated that the US and UK would pool their resources to develop nuclear weapons, and that neither country would use them against the other, or against other countries without mutual consent, or pass information about them to other countries. It also gave the United States a veto over post-war British commercial or industrial uses of nuclear energy. The agreement merged the British Tube Alloys project with the American Manhattan Project, and created the Combined Policy Committee to control the joint project. Although Canada was not a signatory, the Agreement ... [...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 ...

Manhattan Project
The Manhattan Project was a research and development undertaking during World War II that produced the first nuclear weapons. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the United States Army Corps of Engineers, U.S. Army Corps of Engineers. Nuclear physicist Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the actual bombs. The Army component of the project was designated the Manhattan District as its first headquarters were in Manhattan; the placename gradually superseded the official codename, Development of Substitute Materials, for the entire project. Along the way, the project absorbed its earlier British counterpart, Tube Alloys. The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (equivalent to about $ billion in ). Over 90 percent of th ...

Armistice Of Cassibile
The Armistice of Cassibile was an armistice signed on 3 September 1943 and made public on 8 September between the Kingdom of Italy and the Allies during World War II. It was signed by Major General Walter Bedell Smith for the Allies and Brigade General Giuseppe Castellano for Italy at a conference of generals from both sides in an Allied military camp at Cassibile, in Sicily, which had recently been occupied by the Allies. The armistice was approved by both the Italian King Victor Emmanuel III and Marshal Badoglio, the Prime Minister of Italy at the time. Germany moved rapidly by freeing Benito Mussolini (12 September) and attacking Italian forces in Italy (8–19 September), southern France and the Balkans. The Italian forces were quickly defeated, and most of Italy was occupied by German troops, who established a puppet state, the Italian Social Republic. The king, the Italian government, and most of the navy escaped to territories occupied by the Allies. Backgroun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allied Invasion Of Sicily
The Allied invasion of Sicily, also known as Operation Husky, was a major campaign of World War II in which the Allied forces invaded the island of Sicily in July 1943 and took it from the Axis powers ( Fascist Italy and Nazi Germany). It began with a large amphibious and airborne operation, followed by a six-week land campaign, and initiated the Italian campaign. To divert some of the Axis forces to other areas, the Allies engaged in several deception operations, the most famous and successful of which was Operation Mincemeat. Husky began on the night of 9–10 July 1943 and ended on 17 August. Strategically, Husky achieved the goals set out for it by Allied planners; the Allies drove Axis air, land and naval forces from the island and the Mediterranean sea lanes were opened for Allied merchant ships for the first time since 1941. These events led to the Italian leader, Benito Mussolini, being toppled from power in Italy on 25 July, and to the Allied invasion of Italy on 3 ...
