Fort De Loncin
The Fort de Loncin is one of twelve forts built around Liège, Belgium, in the late 19th century. The overall Fortified Position of Liège was a constituent part of the country's National Redoubt (Belgium), National Redoubt. Fort de Loncin was constructed between 1881 and 1884 according to the plans of General Henri Alexis Brialmont. Contrasting with the French forts built in the same era by Raymond Adolphe Séré de Rivières, the fort was built exclusively of unreinforced concrete, a new material, rather than masonry. The experimental nature of the new material, and the design features of the fort, led to unintended consequences in combat action. Weak concrete made the fort vulnerable to enemy artillery, while poor living conditions reduced the fort's ability to operate under fire. The fort was destroyed during World War I in the Battle of Liège, when the fort's magazine was hit by a large-calibre German shell, killing most of the fort's occupants. The event marked the debut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fortified Position Of Liège
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls). A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they acted ...

Enfilade
Enfilade and defilade are concepts in military tactics used to describe a military formation's exposure to enemy fire. A formation or position is "in enfilade" if weapon fire can be directed along its longest axis. A unit or position is "in defilade" if it uses natural or artificial obstacles to shield or conceal itself from enfilade and hostile fire. The strategies, named by the English during the Hundred Years' War, use the French '' enfiler'' ("to put on a string or sling") and ''défiler'' ("to slip away or off") spoken by English nobility of the time. Enfilade fire—gunfire directed against an enfiladed formation or position—is also commonly known as "flanking fire". Raking fire is the equivalent term in naval warfare. Strafing, firing on targets from a flying platform, is often done with enfilade fire. It is a very advantageous, and much sought for, position for the attacking force.

Black Powder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good propellant but is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort De Hollogne
The Fort de Hollogne is one of twelve forts built around Liège, Belgium, in the late 19th century. The overall Fortified Position of Liège was a constituent part of the country's National Redoubt. Fort de Hollogne was built between 1881 and 1884 according to the plans of General Henri Alexis Brialmont. Contrasting with the French forts built in the same era by Raymond Adolphe Séré de Rivières, the fort was built exclusively of unreinforced concrete, a new material, rather than masonry. The fort was heavily bombarded by German artillery in the Battle of Liège. Hollogne was never upgraded like the other forts of Liège and retains its character as a Brialmont fort. It is preserved as a museum and may be visited by the public. Description The Fort de Hollogne is located about west of the Liège city centre, directly adjacent to the Liège Airport's runway. The fort forms an isosceles triangle whose base is long and whose sides measure . A deep by ditch encircles the for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cockerill-Sambre
Cockerill-Sambre was a group of Belgian steel manufacturers headquartered in Seraing, on the river Meuse, and in Charleroi, on the river Sambre. The Cockerill-Sambre group was formed in 1981 by the merger of two Belgian steel groups – SA Cockerill-Ougrée based at Seraing in the province of Liège, and Hainaut-Sambre based at Charleroi in the province of Hainaut – both being the result of post-World War II consolidations of the Belgian steel industry. The company inherited a steel industry with significant debts and production overcapacity based on blast furnace production rather than electric furnace recycling, with numerous factory sites in constrained city locations, and adversely affected by competition in the export market from new steel-producing countries (such as South Korea and Brasil). The need to streamline was complicated by regional dependence on employment in the steel industry. It was merged into Usinor in 1999, and after 2002 was part of the Arcelor group. A ...

Essen
Essen (; Latin: ''Assindia'') is the central and, after Dortmund, second-largest city of the Ruhr, the largest urban area in Germany. Its population of makes it the fourth-largest city of North Rhine-Westphalia after Cologne, Düsseldorf and Dortmund, as well as the ninth-largest city of Germany. Essen lies in the larger Rhine-Ruhr Metropolitan Region and is part of the cultural area of Rhineland. Because of its central location in the Ruhr, Essen is often regarded as the Ruhr's "secret capital". Two rivers flow through the city: in the north, the Emscher, the Ruhr area's central river, and in the south, the Ruhr River, which is dammed in Essen to form the Lake Baldeney (''Baldeneysee'') and Lake Kettwig (''Kettwiger See'') reservoirs. The central and northern boroughs of Essen historically belong to the Low German ( Westphalian) language area, and the south of the city to the Low Franconian ( Bergish) area (closely related to Dutch). Essen is seat to several of the region's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Société Des Forges De Châtillon-Commentry-Neuves-Maisons
The Compagnie anonyme de Châtillon et Commentry was a French steelmaking company, formed as a limited company in 1862 from the Société Bouguéret, Martenot et Cie., a creation from the combination of several French iron makers in 1846. In 1898 the company merged with the Société métallurgique de Champigneulles et Neuves-Maisons to form the Société des forges de Châtillon-Commentry-Neuves-Maisons. In 1979 the works became part of Usinor, forming part of the Unimetal division in 1984. By 2000 the plant in Neuves-Maisons had become part of the Riva Group and as of 2011 produces mainly long products including rebar from scrap metal using electric arc furnaces. History Compagnie anonyme de Châtillon et Commentry Metal working in the Châtillonais region dated back to the Iron Age, with a ready supply of wood from the region's forests, and near surface deposits of iron ore the area became one of the major production centres of iron in France in the 19th century, the c ...

Schneider-Creusot
Schneider et Cie, also known as Schneider-Creusot for its birthplace in the French town of Le Creusot, was a historic French iron and steel-mill company which became a major arms manufacturer. In the 1960s, it was taken over by the Belgian Empain group and merged with it in 1969 to form Empain-Schneider, which in 1980 was renamed Schneider SA and in 1999, after much restructuring, Schneider Electric. Origins In 1836, Adolphe Schneider and his brother Eugène Schneider bought iron-ore mines and forges around Le Creusot (Saône-et-Loire). They developed a business dealing in steel, railways, armaments, and shipbuilding. The Creusot steam hammer was built in 1877. Somua, a subsidiary located near Paris, made machinery and vehicles, including the SOMUA S35 tank.

Krupp
The Krupp family (see pronunciation), a prominent 400-year-old German dynasty from Essen, is notable for its production of steel, artillery, ammunition and other armaments. The family business, known as Friedrich Krupp AG (Friedrich Krupp AG Hoesch-Krupp after acquiring Hoesch AG in 1991 and lasting until 1999), was the largest company in Europe at the beginning of the 20th century, and was the premier weapons manufacturer for Germany in both world wars. Starting from the Thirty Years' War until the end of the Second World War, it produced battleships, U-boats, tanks, howitzers, guns, utilities, and hundreds of other commodities. The dynasty began in 1587 when trader Arndt Krupp moved to Essen and joined the merchants' guild. He bought and sold real estate, and became one of the city's richest men. His descendants produced small guns during the Thirty Years' War and eventually acquired fulling mills, coal mines and an iron forge. During the Napoleonic Wars, Friedrich Kr ...
