Operation Big Bang
Operation Big Bang or British Bang was the explosive destruction of bunkers and other military installations on the island of Heligoland. The explosion used 7400 tons (6700 metric tons) of surplus World War II ammunition, which was placed in various locations around the island and detonated at 1 p.m. on 18 April 1947 by the Royal Navy. The energy released was 1.3×1013 J, or about 3.2 kilotons of TNT equivalent making it the largest artificial non-nuclear explosion at that time. The objective of the blast was to destroy the bunkers and military installations on the North Sea island of Heligoland, but due to the enormous amount of explosives it was foreseen that the entire island might be destroyed. The porous sandstone that makes up the island allowed the blast wave to escape so only the southern tip of the island was destroyed, but there was considerable damage to the northern tip. Background Because of its location in the centre of the German Bight, near the mouths of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Düne
Düne (Danish: ''Dynen'', North Frisian: ''de Halem'') is one of two islands in the German Bight that form the Archipelago of Heligoland, the other being Heligoland proper. Geography The small island of Düne is part of the German State of Schleswig-Holstein. Situated to the east of the main island Heligoland, Düne is part of the ''Heligoland'' protected natural area. The island measures in length and in width. The island is separated from Heligoland proper by the Rede strait. History Until the 17th century, Düne was connected to Heligoland. On New Year's Eve 1721 a big storm surge separated the dunes from Heligoland. Therefore, the island that arose was called Düne ''(English: Dune)''. In 1935 the size of the island was . In 1940 the National Socialist government increased the size of the island to . This increase was for use as a military airfield. The Heligoland Airfield Heligoland Airport (also known as Helgoland Airfield) is an airfield on the German island of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second Battle Of Heligoland Bight
The Second Battle of Heligoland Bight, also the Action in the Helgoland Bight and the , was an inconclusive naval engagement fought between British and German squadrons on 17 November 1917 during the First World War. Background British minelaying The British used sea mining defensively to protect sea lanes and trade routes and offensively to impede the transit of German submarines and surface ships in the North Sea, the danger of which was illustrated on 17 October 1917 by the sortie of the German ''Brummer''-class cruisers and (the action off Lerwick) against the Scandinavian Convoy. (During 1917, six U-boats were sunk by British mines and in two years, the German minesweeping counter-effort suffered the loss about 28 destroyers and 70 minesweepers and other ships.) The Germans had been forced into minesweeping up to into the Heligoland Bight and in the southern Baltic Sea, covered by light cruisers and destroyers, with occasional distant support by battleships.

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive Shock factor, hydraulic shock. Most depth charges use explosive, high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a s ...

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called naval mine, mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with naval artillery, large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface combatant , surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large shi ...

Wehrmacht
The ''Wehrmacht'' (, ) were the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the ''Heer'' (army), the ''Kriegsmarine'' (navy) and the ''Luftwaffe'' (air force). The designation "''Wehrmacht''" replaced the previously used term and was the manifestation of the Nazi regime's efforts to rearm Germany to a greater extent than the Treaty of Versailles permitted. After the Nazi rise to power in 1933, one of Adolf Hitler's most overt and audacious moves was to establish the ''Wehrmacht'', a modern offensively-capable armed force, fulfilling the Nazi régime's long-term goals of regaining lost territory as well as gaining new territory and dominating its neighbours. This required the reinstatement of conscription and massive investment and defense spending on the arms industry. The ''Wehrmacht'' formed the heart of Germany's politico-military power. In the early part of the Second World War, the ''Wehrmacht'' employed combined arms tactics (close-cover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Air Force
The Royal Air Force (RAF) is the United Kingdom's air and space force. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by regrouping the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security".

British Occupation Zone In Germany
The British occupation zone in Germany (German: ''Britische Besatzungszone Deutschlands'') was one of the Allied-occupied areas in Germany after World War II. The United Kingdom along with her Commonwealth were one of the three major Allied powers who defeated Nazi Germany. In 1945 the allies had divided the country into four occupation zones: British, Soviet, American and French lasting until 1949 from whence the new country of West Germany was established. Out of all zones, the British had the largest population and contained within the heavy industry region, the Ruhr, as well as the naval ports and Germany's North West coast line. Background By the end of 1942, Britain was already thinking about post war strategy, and in particular the occupation of Germany. This became more of a reality when the British Liberation Army consisting largely of the 21st Army Group had landed in Normandy on 6 June 1944. Having fought all the way into Northern France and the Low Countries they h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Project Hummerschere
Project Hummerschere (English: ''Project Lobster Claw'') was a construction project proposed by Nazi Germany's ''Kriegsmarine'' to expand the naval facilities on the island of Heligoland in the years leading up to World War II. Intended to create a large naval installation for operations in the North Sea, the plan involved expanding the island to its pre-1629 dimensions, restoring large areas which had been eroded by the sea. Construction was planned to more than double the usable area of both islands of Heligoland, allowing for the creation of a major naval base and Luftwaffe installation.Drower, George (2011). Heligoland: The True Story of German Bight and the Island That Britain Forgot. Stroud, UK: History Press. . Conceived by German Admiral Erich Raeder, the extensive project began in 1937.

Treaty Of Versailles
The Treaty of Versailles (french: Traité de Versailles; german: Versailler Vertrag, ) was the most important of the peace treaties of World War I. It ended the state of war between Germany and the Allied Powers. It was signed on 28 June 1919 in the Palace of Versailles, exactly five years after the assassination of Archduke Franz Ferdinand, which led to the war. The other Central Powers on the German side signed separate treaties. Although the armistice of 11 November 1918 ended the actual fighting, it took six months of Allied negotiations at the Paris Peace Conference to conclude the peace treaty. The treaty was registered by the Secretariat of the League of Nations on 21 October 1919. Of the many provisions in the treaty, one of the most important and controversial was: "The Allied and Associated Governments affirm and Germany accepts the responsibility of Germany and her allies for causing all the loss and damage to which the Allied and Associated Governments and the ...
