Flèche (fortification)
A flèche ( Fr. for "arrow") is an outwork consisting of two converging faces with a parapet and an open gorge, forming an arrowhead shape facing the enemy. by Stephen Francis Wyley. Retrieved 23 May 2015. The flèche is similar in plan to other defensive works like the (or demi-lune), but smaller and built in front of the . It was thus part of the outworks of a fortress. It was usually placed in f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Redan Fleche
Redan (a French word for "projection", "salient") is a feature of fortifications. It is a work in a V-shaped salient angle towards an expected attack. It can be made from earthworks or other material. The redan developed from the lunette, originally a half-moon-shaped outwork; with shorter flanks it became a redan. History Redans were a common feature in the coastal batteries built in Malta between 1715 and the end of the 18th century. Surviving batteries with redans include Mistra Battery and Saint Anthony's Battery. The Russians used redans on their left at the Battle of Borodino against Napoleon. A small redan whose faces make an obtuse angle with a vertex toward the enemy is called a ''flèche'' (arrow in French). The ''Bagration flèches'' were three redans backwards in echelon. The Shevardino Redoubt (another redan) was erected as an early warning post a mile in front of the Bagration flèches. The "Redan hole" in golf A ''Redan hole'' or ''Redan'' is an aspe ...

French Language
French ( or ) is a Romance language of the Indo-European family. It descended from the Vulgar Latin of the Roman Empire, as did all Romance languages. French evolved from Gallo-Romance, the Latin spoken in Gaul, and more specifically in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French ( Francien) largely supplanted. French was also influenced by native Celtic languages of Northern Roman Gaul like Gallia Belgica and by the ( Germanic) Frankish language of the post-Roman Frankish invaders. Today, owing to France's past overseas expansion, there are numerous French-based creole languages, most notably Haitian Creole. A French-speaking person or nation may be referred to as Francophone in both English and French. French is an official language in 29 countries across multiple continents, most of which are members of the ''Organisation internationale de la Francophonie'' ...

Outwork
An outwork is a minor fortification built or established outside the principal fortification limits, detached or semidetached. Outworks such as ravelins, lunettes (demilunes), flèches and caponiers to shield bastions and fortification curtains from direct battery were developed in the 16th century. Later, the increasing scale of warfare and the greater resources available to the besieger accelerated this development, and systems of outworks grew increasingly elaborate and sprawling as a means of slowing the attacker's progress and making it more costly. When taken by an enemy force, their lack of rear-facing ramparts left them totally open to fire from the main works. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gorge (fortification)
A gorge in field fortification is the "unexposed side of a fieldwork", typically the rear of an independent fieldwork or detached outwork in front of the main fortress or defensive position. Outworks with open gorges Straith describes three commonly used classes of field work: "works open at the gorge, works enclosed all round and lines." He lists the following as works open at the gorge: * Redan * Lunette * Redan with flanks * Double Redan * Tenaille-head * Bastion-head Closed works are the redoubt, star fort and bastion A bastion or bulwark is a structure projecting outward from the curtain wall of a fortification, most commonly angular in shape and positioned at the corners of the fort. The fully developed bastion consists of two faces and two flanks, with fi ...ed fort. Gorges of 'half-closed works' were usually closed either by a parapet or stockade.

Ravelin
A ravelin is a triangular fortification or detached outwork, located in front of the innerworks of a fortress (the curtain walls and bastions). Originally called a ''demi-lune'', after the ''lunette'', the ravelin is placed outside a castle and opposite a fortification curtain wall. The ravelin is the oldest and at the same time the most important outer work of the bastion fortification system. It originated from small forts that were supposed to cover the bridge that led across the moat to the city or fortress gate from a direct attack. From this original function, to protect the gate bridge, also comes its original Italian name "''rivellino''" (which means small bank work or with the German expression common for it: ''Brückenkopf'' – "bridge head"). Therefore, the ravelin was at first only a small work, which should only make the access to the bridge in front of the fortress gates more difficult. When it was realized in the 16th century that this would generally provid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacis
A glacis (; ) in military engineering is an artificial slope as part of a medieval castle or in bastion fort, early modern fortresses. They may be constructed of earth as a temporary structure or of stone in more permanent structure. More generally, a glacis is any slope, natural or artificial, which fulfils the above requirements. The etymology of this French word suggests a slope made dangerous with ice, hence the relationship with ''glacier''. A ''glacis plate'' is the sloped armour, sloped front-most section of the hull of a tank or other armoured fighting vehicle. Ancient fortifications A glacis could also appear in ancient fortresses, such as the one the ancient Egyptians built at Semna (Nubia), Semna in Nubia. Here it was used by them to prevent enemy siege engines from weakening defensive walls. Hillforts in Britain started to incorporate glacis around 350 BC. Those at Maiden Castle, Dorset, Maiden Castle, Dorset were high. Medieval fortifications Glacis, also call ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bastion
A bastion or bulwark is a structure projecting outward from the curtain wall of a fortification, most commonly angular in shape and positioned at the corners of the fort. The fully developed bastion consists of two faces and two flanks, with fire from the flanks being able to protect the curtain wall and the adjacent bastions. Compared with the medieval fortified towers they replaced, bastion fortifications offered a greater degree of passive resistance and more scope for ranged defence in the age of gunpowder artillery. As military architecture, the bastion is one element in the style of fortification dominant from the mid 16th to mid 19th centuries. Evolution By the middle of the 15th century, artillery pieces had become powerful enough to make the traditional medieval round tower and curtain wall obsolete. This was exemplified by the campaigns of Charles VII of France who reduced the towns and castles held by the English during the latter stages of the Hundred Years War, ...
