îlot Du Diable
Îlot du Diable is a gun battery built to support fort de la Fraternité in the defensive system around the goulet de Brest in France. It is sited on the peninsula of Roscanvel and is accessible by a small bridge. The battery was razed in the 19th century, and in 1890 on its site was built a bunker with an electricity generator. A casemate was then added by the Germans in 1942. A small observation is still to be found at the summit of the site, near a former lime kiln A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called ''quicklime'' (calcium oxide). The chemical equation for this reaction is: CaCO3 + heat → CaO + CO2 This reaction can tak ....

Gun Battery
In military organizations, an artillery battery is a unit or multiple systems of artillery, mortar systems, rocket artillery, multiple rocket launchers, surface-to-surface missiles, ballistic missiles, cruise missiles, etc., so grouped to facilitate better battlefield communication and command and control, as well as to provide dispersion for its constituent gunnery crews and their systems. The term is also used in a naval context to describe groups of guns on warships. Land usage Historically the term "battery" referred to a cluster of cannons in action as a group, either in a temporary field position during a battle or at the siege of a fortress or a city. Such batteries could be a mixture of cannon, howitzer, or mortar types. A siege could involve many batteries at different sites around the besieged place. The term also came to be used for a group of cannons in a fixed fortification, for coastal or frontier defence. During the 18th century "battery" began to be used as a ...

Fort De La Fraternité
A fortification (also called a fort, fortress, fastness, or stronghold) is a military construction designed for the defense of territories in warfare, and is used to establish rule in a region during peacetime. The term is derived from Latin ("strong") and ("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 cyclopean stone walls fitted without mortar had been built in Mycenaean Greece, such as the ancient site of Mycenae. A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or 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 as a border gu ...

Goulet De Brest
The Goulet de Brest (; ) is a 3-km-long strait linking the roadstead of Brest to the Atlantic Ocean. Only 1.8 km wide, the is situated between the Pointe du Petit Minou and the Pointe du Portzic to the north and the îlot des Capucins and the Pointe des Espagnols to the south. At each turn of the tide, the ocean refills the roadstead in a current that can attain 4 to 5 knot (unit), knots. Sailing ships would thus wait in the cove of Camaret-sur-Mer for a favourable current to carry them into the . On 2 January 1793, the Childers Incident, ''Childers'' Incident – the first shots of the war between Great Britain and France during the French Revolutionary Wars – took place in the . Military significance It is the only opening into the roadstead of Brest, France, Brest, and thus the only access to the town. Consequently, successive French governments have lined the with military installations to protect the town and the naval fleet based there, and to keep a watch on ...

German Occupation Of France During World War II
The Military Administration in France (; ) was an interim occupation authority established by Nazi Germany during World War II to administer the occupied zone in areas of northern and western France. This so-called ' was established in June 1940, and renamed ' ("north zone") in November 1942, when the previously unoccupied zone in the south known as ' ("free zone") was also occupied and renamed ' ("south zone"). Its role in France was partly governed by the conditions set by the Armistice of 22 June 1940 after the success of the leading to the Fall of France; at the time both French and Germans thought the occupation would be temporary and last only until Britain came to terms, which was believed to be imminent. For instance, France agreed that its soldiers would remain prisoners of war until the cessation of all hostilities. The "French State" (') replaced the French Third Republic that had dissolved in defeat. Though nominally extending its sovereignty over the whole co ...

Lime Kiln
A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called ''quicklime'' (calcium oxide). The chemical equation for this reaction is: CaCO3 + heat → CaO + CO2 This reaction can take place at anywhere above , but is generally considered to occur at (at which temperature the partial pressure of CO2 is 1 atmosphere), but a temperature around (at which temperature the partial pressure of CO2 is 3.8 atmospheres) is usually used to make the reaction proceed quickly.Parkes, G.D. and Mellor, J.W. (1939). ''Mellor's Modern Inorganic Chemistry'' London: Longmans, Green and Co. Excessive temperature is avoided because it produces unreactive, "dead-burned" lime. Slaked lime (calcium hydroxide) can be formed by mixing quicklime with water. History Pre-pottery Neolithic In plaster, proto-pottery, and mortar Because it is so readily made by heating limestone, lime must have been known from the earliest times, and all th ...
