Fort Janus
Ouvrage Janus is a work (''gros ouvrage'') of the Maginot Line's Alpine extension, the Alpine Line, located to the east of Briançon on near the Col de Montgenèvre. The ouvrage consists of one entry block, two infantry blocks, two artillery blocks, two observation blocks and one combination block at an altitude of , the second highest fortification on the Alps in 1940. Built on the site of the old Fort Janus, it retained the old fort's 95mm naval guns and added two 75mm guns Kaufmann 2006, p. 177 Fort du Janus The location was known from the end of the 18th century as the Château Jouan, occupied by a Vauban-era round tower. In 1883 a Séré de Rivières system fortification was begun on the massif, called the Fort du Janus. Work continued until 1889 with a blockhouse in top of the position and a rock-cut battery in the face of the mountain, which housed four 95mm naval guns. In 1891-92 the blockhouse was expanded to two levels for a barracks, and from 1898 to 1906 a subterra ...

Maginot Line
The Maginot Line (french: Ligne Maginot, ), named after the French Minister of War André Maginot, is a line of concrete fortifications, obstacles and weapon installations built by France in the 1930s to deter invasion by Germany and force them to move around the fortifications. The Maginot Line was impervious to most forms of attack. In consequence, the Germans invaded through the Low Countries in 1940, passing it to the north. The line, which was supposed to be fully extended further towards the west to avoid such an occurrence, was finally scaled back in response to demands from Belgium. Indeed, Belgium feared it would be sacrificed in the event of another German invasion. The line has since become a metaphor for expensive efforts that offer a false sense of security. Constructed on the French side of its borders with Italy, Switzerland, Germany, Luxembourg and Belgium, the line did not extend to the English Channel. French strategy therefore envisioned a move into Belgium ...

Fortified Sector Of Dauphine
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 ...

List Of Alpine Line Ouvrages
This is the list of all ''ouvrages'' of the Alpine Line or Little Maginot Line along the Franco-Italian border, organized by sector and type of fortification. ''Ouvrage'' translates as "works" in English; publications in both English and French refer to these fortifications in this manner, rather than as "forts". An ''ouvrage'' typically consists of a distributed series of concrete-encased strongpoints defending a region, linked by tunnels, as opposed to a fort, which typically refers to a defended surface enclosure, which may have underground galleries as an adjunct. For a list of the ''ouvrages'' of the main Maginot Line, refer to List of Maginot Line ouvrages. Voici la liste des ouvrages de la Ligne Maginot répartis par Secteurs Fortifiés et types d'ouvrages: Fortified Sector of Savoy (La Tarentaise) Ouvrage * 1 - Ouvrage Chatelard (PO) * 1 - Ouvrage Cave Canon (PO) Fortified Sector of Savoy (La Maurienne) Ouvrages * 2 - Ouvrage Sapey (GO) * 3 - Ouvrage Saint ...

19th Army (Wehrmacht)
The 19th Army (German: ''19. Armee'') was a World War II field army of the German Army. History Formed in August 1943 in occupied southern France from ''Armeegruppe Felber'' (the '' LXXXIII. Armeekorps''), the 19th Army defended southern France, the Vosges Mountains, Alsace, Baden and southern Württemberg during the Allied invasion of southern France and other large Allied military operations that had as their goal the liberation of southern France and the invasion of southern Germany. Although nominally a field army, the 19th Army was under strength and consisted of third tier soldiers, wounded veterans, conscripts and Hiwis. Southern France in general was treated as a third tier theatre and given minimal attention by the OKW. The entire army was outfitted with damaged and obsolete equipment, with four of the 19th army's divisions designated "static divisions," meaning that they were stripped of all mobile assets and forbidden to move from their assigned positions. The Hi ...

VDP Cloche
The VDP cloche was an element of the Maginot Line fortifications. A ''cloche'' (bell) was a fixed and non-retractable firing position made of a thick iron casting which shielded its occupant. By comparison, turrets could be rotated and sometimes lowered so that only the top shell was exposed. VDP cloches were used for observation of the surrounding area for artillery direction. VDP is an acronym for ''Vision Directe et Périscopique''. By comparison with the GFM cloche, the VDP cloche had narrower ports and was consequently lower in profile. Description VDP cloches were equipped with three embrasures or crenels for direct vision, providing protection to observers. VDP cloches were also equipped with periscopes that allowed a greater arc of view. The cloches were embedded in a thick concrete carapace over a combat, entrance or observation block element of a largely subterranean Maginot fortification. A platform, identical to that used in the GFM cloche, was installed for the obser ...

JM Cloche
The JM cloche is an element of the Maginot Line. It is a non-retractable non-rotating cupola of steel alloy like GFM cloches, but are armed with twin heavy machine guns, as opposed to the lighter automatic rifles associated with the GFM. There are 179 JM cloches on the Maginot Line. JM is an acronym for ''Jumelage de Mitrailleuses'' (twin machine guns). While the MAC 31 heavy machine guns were of the same caliber (7.5mm) as those in GFM cloches, they had a longer practical range and a maximum range of , with a 500 round per minute rate of fire.Mary, Tome 2, page 109 Description The JM cloche closely resembles the GFM cloche in size and construction. It exists in three versions, all designed Model 1930: small, large and two-man. JM cloches had a single firing port, which was flanked on either side by trapezoidal observation ports. The blank rear was frequently backed by a concrete-covered embankment, which provided additional cover and reduced the prominence of the cloche. AM ...

Ouvrage Gondran
Ouvrage Gondran is a lesser work (''petit ouvrage'') of the Maginot Line's Alpine extension, the Alpine Line. The ouvrage consists of one entry block, one infantry block and one observation block. Gondran was commenced in June 1933, and was intended to cover the gap between Janus and Les Aittes. The site is close to two older forts, designated Gondran C and Gondran D. The Maginot fortification became known as Gondran E.Mary, Tome 5, p. 28 The fortified area is near the Les Gondrans portion of the Montgenèvre ski area. Description :''See Fortified Sector of the Dauphiné for a broader discussion of the Dauphiné sector of the Alpine Line.'' The ''ouvrage'' was never completed. As the emergency exit was on the same level as the main portion it was used during peacetime as the main entrance. It is sometimes called "Gondran E."Kaufmann 2011, p. 261 *Block 1 (entry): one machine gun cloche and one heavy twin machine gun embrasure. *Block 2 (infantry): one machine gun embrasure. *Bl ...

Alpine Line
The Alpine Line (french: Ligne Alpine) or Little Maginot Line (French: ''Petite Ligne Maginot'') was the component of the Maginot Line that defended the southeastern portion of France. In contrast to the main line in the northeastern portion of France, the Alpine Line traversed a mountainous region of the Maritime Alps, the Cottian Alps and the Graian Alps, with relatively few passes suitable for invading armies. Access was difficult for construction and for the Alpine Line garrisons. Consequently, fortifications were smaller in scale than the fortifications of the main Line. The Alpine Line mounted few anti-tank weapons, since the terrain was mostly unsuitable for the use of tanks. Ouvrage Rimplas was the first Maginot fortification to be completed on any portion of the Maginot Line, in 1928. The Alpine Line was unsuccessfully attacked by Italian forces during the Italian invasion of France in 1940. Following World War II, some of the larger positions of the Alpine Line were retai ...

Séré De Rivières System
The system was named after Raymond Adolphe Séré de Rivières, its originator. The system was an ensemble of fortifications built from 1874 along the frontiers and coasts of France. The fortresses were obsolescent by 1914 but were used during the First World War. Background Following the Franco-Prussian War of 1870–1871, France found itself seriously weakened and isolated from the rest of Europe, menaced by Germany and stung by the loss of Alsace-Lorraine. At the same time as the departure of the last German troops, France created the Defence Committee (), which was active between 1872 and 1888, whose mission was to reorganize the defence of the French frontiers and coasts. It was necessary to compensate for the lost territories of the north-east; to modernise old fortifications, which had been shown to be wanting in the last war and to create new fortifications proof against modern weaponry using new and more powerful explosives. The committee was created by a preside ...
