A reduit is a fortified structure such as a citadel or a keep into which the defending troops can retreat when the outer defences are breached. [1] The term is also used to describe an area of a country that, through a ring of heavy fortifications or through enhancing through fortification the defences offered by natural features such as mountains, will be defended even when the rest of the country is occupied by a hostile power. [2]
In English the term National redoubt is fairly commonly used. A redoubt is an outlying fortification, so its use to describe the Nazis' National Redoubt in the German and Austrian Alps is an accurate description. [2] However another term that is sometimes used in English and more frequently used in French is "national reduit" (réduit national) to describe the holding of the centre of a country while abandoning outlying territory.
Examples of this usage are:
A bunker is a defensive military fortification designed to protect people and valued materials from falling bombs, artillery, or other attacks. Bunkers are almost always underground, in contrast to blockhouses which are mostly above ground. They were used extensively in World War I, World War II, and the Cold War for weapons facilities, command and control centers, and storage facilities. Bunkers can also be used as protection from tornadoes.
A national redoubt or national fortress is an area to which the (remnant) military forces of a nation can be withdrawn if the main battle has been lost or even earlier if defeat is considered inevitable. Typically, a region is chosen with a geography favouring defence, such as a mountainous area or a peninsula, to function as a final holdout to preserve national independence and host an effective resistance movement for the duration of the conflict.
Operation Tannenbaum, known earlier as Operation Grün ("Green"), was a planned invasion of Switzerland and Liechtenstein by the Axis Powers during World War II.
A blockhouse is a small fortification, usually consisting of one or more rooms with loopholes, allowing its defenders to fire in various directions. It is usually an isolated fort in the form of a single building, serving as a defensive strong point against any enemy that does not possess siege equipment or, in modern times, artillery, air force or cruise missiles. A fortification intended to resist these weapons is more likely to qualify as a fortress or a redoubt, or in modern times, be an underground bunker. However, a blockhouse may also refer to a room within a larger fortification, usually a battery or redoubt.
The National Redoubt was a strategic defensive belt of fortifications built in Belgium. The National redoubt was the infrastructural cornerstone of Belgian defensive strategy from 1890–1940.
Festung is a generic German word for a fortress. Although it is not in common usage in English, it is used in a number of historical contexts involving German speakers:
During World War I and World War II, Switzerland maintained armed neutrality, and was not invaded by its neighbors, in part because of its topography, much of which is mountainous. Germany was a threat, and Switzerland built a powerful defense. It served as a "protecting power" for the belligerents of both sides, with a special role in helping prisoners of war. The belligerent states made it the scene for diplomacy, espionage, and commerce, as well as being a safe haven for 300,000 refugees.
Fortress Europe was a military propaganda term used by both sides of World War II which referred to the areas of Continental Europe occupied by Nazi Germany, as opposed to the United Kingdom across the Channel.
A redoubt is a fort or fort system usually consisting of an enclosed defensive emplacement outside a larger fort, usually relying on earthworks, although some are constructed of stone or brick. It is meant to protect soldiers outside the main defensive line and can be a permanent structure or a hastily constructed temporary fortification. The word means "a place of retreat". Redoubts were a component of the military strategies of most European empires during the colonial era, especially in the outer works of Vauban-style fortresses made popular during the 17th century, although the concept of redoubts has existed since medieval times. A redoubt differs from a redan in that the redan is open in the rear, whereas the redoubt was considered an enclosed work.
The Fortress of Mainz was a fortressed garrison town between 1620 and 1918. At the end of the Napoleonic Wars, under the term of the 1815 Peace of Paris, the control of Mainz passed to the German Confederation and became part of a chain of strategic fortresses which protected the Confederation. With the dissolution of the Confederation and the Austro-Prussian War, control of the fortress first passed to Prussia, and, after the 1871 Unification of Germany, to the German Empire.
Under the terms of the 1815 Peace of Paris, France was obliged to pay for the construction of a line of fortresses to protect the German Confederation against any future aggression by France. All fortresses were located outside Austria and Prussia — the two biggest, bickering powers of the Confederation.
The Fort du Trou-d'Enfer, also known as the Réduit du Trou-d'Enfer, is one of the fortifications of Paris, It is located in Marly-le-Roi, in the departement of Yvelines. The fort was built between 1878 and 1881 for a garrison of 800 men. It was termed a réduit for its position surrounded by several smaller batteries. The fort was occupied by the Germans during World War II, who blew up their ammunition when they evacuated the fort in August 1944, damaging the fort. The fort is named for the farm on whose land it sits, the ferme du trou-d'enfer, literally "Hellhole Farm."
The fortified position of Liège was established after the First World War by Belgium to block the traditional invasion corridor through Belgium between Germany and France. In the First World War the Belgian Army held up the Germans for a week at Liège, delaying the German invasion of France, caused Belgium to consider a similar defensive strategy. Belgium rebuilt the Liège fortifications and extended them onto the Pays de Herve closer to Germany, using the most advanced fortification technology available.
The Swiss National Redoubt is a defensive plan developed by the Swiss government beginning in the 1880s to respond to foreign invasion. In the opening years of the Second World War the plan was expanded and refined to deal with a potential German invasion. The term "National Redoubt" primarily refers to the fortifications begun in the 1880s that secured the mountainous central part of Switzerland, providing a defended refuge for a retreating Swiss Army.
The German invasion of Belgium was a military campaign which began on 4 August 1914. On 24 July, the Belgian government had announced that if war came it would uphold its neutrality. The Belgian government mobilised its armed forces on 31 July and a state of heightened alert was proclaimed in Germany. On 2 August, the German government sent an ultimatum to Belgium, demanding passage through the country and German forces invaded Luxembourg. Two days later, the Belgian government refused the German demands and the British government guaranteed military support to Belgium. The German government declared war on Belgium on 4 August; German troops crossed the border and began the Battle of Liège.
Reduit or Réduit may refer to:
Vendôme Tower is a tour-reduit in Marsaxlokk, Malta. It was built by the Order of Saint John in 1715 as one of a series of fortifications around the coasts of the Maltese Islands. It is the only surviving tour-reduit in Malta. Today, Vendôme Tower houses the headquarters of Marsaxlokk F.C.
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.
The Valtellina Redoubt or, officially, in Italian: Ridotto Alpino Repubblicano or RAR, was the intended final stronghold or redoubt of the Italian fascist regime of Benito Mussolini at the end of World War II in Europe. It was to be based in the Valtellina, a valley in the Italian Alps, which had the natural protection afforded by the surrounding mountains as well as the possibility of re-using fortifications built in the area for World War I. The idea was initially proposed in September 1944 by Alessandro Pavolini, one of the fascist leaders, who saw it as the place for the regime to make a "heroic" last stand which would inspire a future fascist revolution.
