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 g ...

Fort I Grundriss
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 ''Towns of ancient Greece#Military settlements, phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the ancient Roman, Roman castellum or English language, English fortress. These constructions mainly served the purpose of a watch tower, to guard certa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casemate
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 ...

Jean Le Michaud D'Arçon
Jean Claude Eléonore Le Michaud d’Arçon (18 November 1733 – 1 July 1800) was a French general, specializing in fortification. His designs include the forts at Pontarlier and Fort-Dauphin in Queyras. Life Early life He was the son of a lawyer who also wrote several short works on ancient custom of the Franche-Comté. Jean Claude was born in Besançon and was originally intended for a career in the church – he was sent to view a parish to win him round to this career, but he was keener on an army career, drawing and mapping fortifications instead of studying Latin. When someone was sent to draw his portrait for his parents, he opted to be shown in the dress of an engineer not a clergyman and his father agreed to support his choice of career. He studied at the École royale du génie de Mézières in 1754 and was made an engineer-in-ordinary the following year, fighting with distinction in the Seven Years' War, particularly in the defence of Hesse-Kassel in 1761.

French Revolution
The French Revolution ( ) was a period of radical political and societal change in France that began with the Estates General of 1789 and ended with the formation of the French Consulate in November 1799. Many of its ideas are considered fundamental principles of liberal democracy, while phrases like '' liberté, égalité, fraternité'' reappeared in other revolts, such as the 1917 Russian Revolution, and inspired campaigns for the abolition of slavery and universal suffrage. The values and institutions it created dominate French politics to this day. Its causes are generally agreed to be a combination of social, political and economic factors, which the ''Ancien Régime'' proved unable to manage. In May 1789, widespread social distress led to the convocation of the Estates General, which was converted into a National Assembly in June. Continuing unrest culminated in the Storming of the Bastille on 14 July, which led to a series of radical measures by the Assemb ...

Charles Louis De Fourcroy
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its depre ...

Louis De Cormontaigne
Louis de Cormontaigne (, 1696-1752) was a French military engineer, who was the dominant technical influence on French fortifications in the 18th century. His own designs and writings constantly referenced the work of Vauban (1633-1707) and his principles formed the basis of the curriculum used by the École royale du génie, established at Charleville-Mézières in 1744. Life Louis de Cormontaigne was born in Strasbourg in Alsace, a city part of the Holy Roman Empire until 1681, when it was annexed by France. His family are described as ''escuyer'' or esquire, making him a member of the minor gentry. He married Marie Aimé de Gougon and they had a daughter Marie Antoinette (1749-?), whose husband was Maurice Regnault (1740-?), an official of the Regional Parliament of Lorraine. He died in Metz on 30 March 1752. Career De Cortmontaigne joined the French army in 1713, participating in the Rhineland campaign, the final part of the War of the Spanish Succession before p ...

Gerhard Von Scharnhorst
Gerhard Johann David von Scharnhorst (12 November 1755 – 28 June 1813) was a Hanoverian-born general in Prussian service from 1801. As the first Chief of the Prussian General Staff, he was noted for his military theories, his reforms of the Prussian army, and his leadership during the Napoleonic Wars. Scharnhorst limited the use of corporal punishments, established promotion for merit, abolished the enrollment of foreigners, began the organization of a reserve army, and organized and simplified the military administration. Biography Born at Bordenau (now a part of Neustadt am Rübenberge, Lower Saxony) near Hanover, into a small landowner's family, Scharnhorst succeeded in educating himself and in securing admission to the military academy of William, Count of Schaumburg-Lippe, at the Wilhelmstein fortress. In 1778 he received a commission into the Hanoverian service. He employed the intervals of regimental duty in further self-education and literary work. In 1783 he trans ...

Prussian Army
The Royal Prussian Army (1701–1919, german: Königlich Preußische Armee) served as the army of the Kingdom of Prussia. It became vital to the development of Brandenburg-Prussia as a European power. The Prussian Army had its roots in the core mercenary forces of Brandenburg during the Thirty Years' War of 1618–1648. Elector Frederick William developed it into a viable standing army, while King Frederick William I of Prussia dramatically increased its size and improved its doctrines. King Frederick the Great, a formidable battle commander, led the disciplined Prussian troops to victory during the 18th-century Silesian Wars and greatly increased the prestige of the Kingdom of Prussia. The army had become outdated by the beginning of the Napoleonic Wars, and France defeated Prussia in the War of the Fourth Coalition in 1806. However, under the leadership of Gerhard von Scharnhorst, Prussian reformers began modernizing the Prussian Army, which contributed greatly to the d ...

Defence In Depth
Defence in depth (also known as deep defence or elastic defence) is a military strategy that seeks to delay rather than prevent the advance of an attacker, buying time and causing additional casualties by yielding space. Rather than defeating an attacker with a single, strong defensive line, defence in depth relies on the tendency of an attack to lose momentum over time or as it covers a larger area. A defender can thus yield lightly defended territory in an effort to stress an attacker's logistics or spread out a numerically superior attacking force. Once an attacker has lost momentum or is forced to spread out to pacify a large area, defensive counter-attacks can be mounted on the attacker's weak points, with the goal being to cause attrition or drive the attacker back to its original starting position. Strategy A conventional defence strategy would concentrate all military resources at a front line, which, if breached by an attacker, would leave the remaining defenders in ...
