42 Cm Gamma Mörser
The 42 cm ''kurze Marinekanone'' L/12, or ''Gamma-Gerät'' ("Gamma Device"), was a German siege gun built by Krupp. The ''Gamma-Gerät''s barrel diameter was , making it one of the largest artillery pieces ever fielded. The ''Gamma-Gerät'' began development in 1906 and entered service with the Imperial German Army in 1911. The ''Gamma-Gerät'' was the most powerful piece of artillery fielded by the Imperial German Army, but due to its extreme weight was mostly immobile and could only be emplaced near permanent rail lines. As a result, the ''Gamma-Gerät'' had limited effectiveness on the Western and Eastern Fronts of World War I. A total of ten ''Gamma-Gerät'' howitzers were produced, mostly during World War I, and were assigned to a total of six artillery batteries, typically two guns to a battery. These batteries were deployed at various sieges and battles in Belgium, France, Poland, and Serbia. Allied counter-battery fire and internal detonations caused by faulty ammu ...

German Empire
The German Empire (),Herbert Tuttle wrote in September 1881 that the term "Reich" does not literally connote an empire as has been commonly assumed by English-speaking people. The term literally denotes an empire – particularly a hereditary empire led by an emperor, although has been used in German to denote the Roman Empire because it had a weak hereditary tradition. In the case of the German Empire, the official name was , which is properly translated as "German Empire" because the official position of head of state in the constitution of the German Empire was officially a "presidency" of a confederation of German states led by the King of Prussia who would assume "the title of German Emperor" as referring to the German people, but was not emperor of Germany as in an emperor of a state. –The German Empire" ''Harper's New Monthly Magazine''. vol. 63, issue 376, pp. 591–603; here p. 593. also referred to as Imperial Germany, the Second Reich, as well as simply Germany, ...

Counter-battery Fire
Counter-battery fire (sometimes called counter-fire) is a battlefield tactic employed to defeat the enemy's indirect fire elements (multiple rocket launchers, artillery and mortars), including their target acquisition, as well as their command and control components. Counter-battery arrangements and responsibilities vary between nations but involve target acquisition, planning and control, and counter-fire. Counter-battery fire rose to prominence in World War I. Counter-battery radar detects incoming indirect fire and calculates its point of origin. That location data can be sent by a communications link to friendly forces, who can then fire on the enemy positions, hopefully before they can reposition (the "scoot" part of shoot-and-scoot tactics). Counter-RAM systems track incoming rocket, artillery, and mortar fire and attempt to intercept and destroy the projectiles or provide early warning to the target area. Background Indirect fire was introduced so that artillery could fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alfred Von Schlieffen
Graf Alfred von Schlieffen, generally called Count Schlieffen (; 28 February 1833 – 4 January 1913) was a German field marshal and strategist who served as chief of the Imperial German General Staff from 1891 to 1906. His name lived on in the 1905–06 "Schlieffen Plan", then ''Aufmarsch I'', a deployment plan and operational guide for a decisive initial offensive operation/campaign in a two-front war against the French Third Republic. Biography Born in Prussia, Germany, on 28 February 1833 as the son of a Prussian Army officer, he was part of an old Prussian noble family, the Schlieffen family. He lived with his father, Major Magnus von Schlieffen, on their estate in Silesia, which he left to go to school in 1842. Growing up, Schlieffen had shown no interest in joining the military and so he did not attend the traditional Prussian cadet academies. Instead, he studied at the University of Berlin. While he was studying law, he enlisted in the army in 1853 for his one year of co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

German General Staff
The German General Staff, originally the Prussian General Staff and officially the Great General Staff (german: Großer Generalstab), was a full-time body at the head of the Prussian Army and later, the German Army, responsible for the continuous study of all aspects of war, and for drawing up and reviewing plans for mobilization or campaign. It existed unofficially from 1806, and was formally established by law in 1814, the first general staff in existence. It was distinguished by the formal selection of its officers by intelligence and proven merit rather than patronage or wealth, and by the exhaustive and rigorously structured training which its staff officers undertook. Its rise and development gave the German armed forces a major strategic advantage over their adversaries for nearly a century and a half. The Prussian General Staff also enjoyed greater freedom from political control than its contemporaries, and this autonomy was enshrined in law on the unification of Germany ...

National Redoubt (Belgium)
The National Redoubt (french: Réduit national, nl, Stelling van Antwerpen) was a strategic defensive belt of fortifications built in Belgium. The National redoubt was the infrastructural cornerstone of Belgian defensive strategy from 1890–1940. The following fortifications and defensive constructions were an integral part of the National redoubt: * the Fortified Position of Liège (Luik) with a number of forts * the Fortified Position of Namur (Namen) with a number of forts * Fort Eben-Emael * the K-W line: a "canal" from Koningshooikt to Wavre, to defend against tank incursions * another anti-tank canal in the Kempen, roughly aligned with the outer ring of fortifications around Antwerpen * the coastal defenses as a retreat position against invasion troops The most important part of the national redoubt was a double ring of defensive forts around the city and port of Antwerp. The National Redoubt was a -long belt of fortifications built from 1859 to 1914, as the stronges ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casemates
A casemate is a fortified gun emplacement or armored structure from which guns are fired, in a fortification, warship, or armoured fighting vehicle.Webster's New Collegiate Dictionary When referring to antiquity, the term "casemate wall" means a double city wall with the space between the walls separated into chambers, which could be filled up to better withstand battering rams in case of siege (see Antiquity: casemate wall). In its original early modern meaning, the term referred to a vaulted chamber in a fort, which may have been used for storage, accommodation, or artillery which could fire through an opening or embrasure. Although the outward faces of brick or masonry casemates proved vulnerable to advances in artillery performance, the invention of reinforced concrete allowed newer designs to be produced well into the 20th century. With the introduction of ironclad warships, the definition was widened to include a protected space for guns in a ship, either within the hu ...

Polygonal Fort
A polygonal fort is a type of fortification originating in France in the late 18th century and fully developed in Germany in the first half of the 19th century. Unlike earlier forts, polygonal forts had no bastions, which had proved to be vulnerable. As part of ring fortresses, polygonal forts were generally arranged in a ring around the place they were intended to protect, so that each fort could support its neighbours. The concept of the polygonal fort proved to be adaptable to improvements in the artillery which might be used against them, and they continued to be built and rebuilt well into the 20th century. Bastion system deficiencies The bastion system of fortification had dominated military thinking since its introduction in 16th century Italy, until the first decades of the 19th century. The French engineer Sébastien Le Prestre de Vauban, also devised an effective method to defeat them. Before Vauban, besiegers had driven a sap towards the fort, until they reached the gl ...

Artillery Fuze
An artillery fuze or fuse is the type of munition fuze used with artillery munitions, typically projectiles fired by guns (field, anti-aircraft, coast and naval), howitzers and mortars. A fuze is a device that initiates an explosive function in a munition, most commonly causing it to detonate or release its contents, when its activation conditions are met. This action typically occurs a preset time after firing ( time fuze), or on physical contact with (contact fuze) or detected proximity to the ground, a structure or other target ( proximity fuze). Fuze, a variant of fuse, is the official NATO spelling. Terminology Munitions fuzes are also used with rockets, aircraft bombs, guided missiles, grenades and mines, and some direct fire cannon munitions (small calibre and tank guns). Broadly, fuzes function on impact (percussion fuzes) or at a pre-determined time period after firing (time fuzes). However, by the 18th century time fuzes were aimed to function in the air and in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siege Of Sevastopol (1941–1942)
A siege is a military blockade of a city, or fortress, with the intent of conquering by attrition, or a well-prepared assault. This derives from la, sedere, lit=to sit. Siege warfare is a form of constant, low-intensity conflict characterized by one party holding a strong, static, defensive position. Consequently, an opportunity for negotiation between combatants is common, as proximity and fluctuating advantage can encourage diplomacy. The art of conducting and resisting sieges is called siege warfare, siegecraft, or poliorcetics. A siege occurs when an attacker encounters a city or fortress that cannot be easily taken by a quick assault, and which refuses to surrender. Sieges involve surrounding the target to block the provision of supplies and the reinforcement or escape of troops (a tactic known as "investment"). This is typically coupled with attempts to reduce the fortifications by means of siege engines, artillery bombardment, mining (also known as sapping), or the us ...
