Trou De Loup
In medieval fortification, a trou de loup (French for "wolf hole"; plural trous de loup, also commonly referred to as a tiger pit in the East) was a type of booby trap or defensive obstacle. Each trou de loup consisted of a conical pit about deep and wide at the top. At the bottom of the pit, a sharpened punji stick (wooden stake) would be hammered in. In some cases, the pit was concealed by light cover of wicker and a layer of soil. Trous de loup might be found singly as a trap (in which case they were always concealed), or in a dense pattern with no gaps between pits, used as an obstacle in front of a defended position. A field of trous de loup could be made more effective if subsequently flooded to a shallow depth, which would conceal the pits, make their sides slippery, and add the risk of drowning. Sometimes rotting meat or feces would be smeared onto the points to cause serious infection or death. History Even though the term has a medieval origin, this kind of device ...

Medieval Fortification
Medieval fortification refers to medieval military methods that cover the development of fortification construction and use in Europe, roughly from the fall of the Western Roman Empire to the Renaissance. During this millennium, fortifications changed warfare, and in turn were modified to suit new tactics, weapons and siege techniques. Fortification types Archer towers Towers of medieval castles were usually made of stone, wood or a combination of both (with a stone base supporting a wooden loft). Often toward the later part of the era they included battlements and arrow loops. Arrow loops were vertical slits in the wall through which archers inside shot arrows at the attackers, but made it extremely difficult for attackers to get many arrows back through at the defenders. City walls An exact nature of the walls of a medieval town or city would depend on the resources available for building them, the nature of the terrain, and the perceived threat. In northern Europe, ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Booby Trap
A booby trap is a device or setup that is intended to kill, harm or surprise a human or another animal. It is triggered by the presence or actions of the victim and sometimes has some form of bait designed to lure the victim towards it. The trap may be set to act upon trespassers that enter restricted areas, and it can be triggered when the victim performs an action (e.g., opening a door, picking something up, or switching something on). It can also be triggered by vehicles driving along a road, as in the case of improvised explosive devices (IEDs). Booby traps should not be confused with mantraps which are designed to catch a person. Lethal booby traps are often used in warfare, particularly guerrilla warfare, and traps designed to cause injury or pain are also sometimes used by criminals wanting to protect drugs or other illicit property, and by some owners of legal property who wish to protect it from theft. Booby traps which merely cause discomfort or embarrassment are a popul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cone (geometry)
A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex. A cone is formed by a set of line segments, half-lines, or lines connecting a common point, the apex, to all of the points on a base that is in a plane that does not contain the apex. Depending on the author, the base may be restricted to be a circle, any one-dimensional quadratic form in the plane, any closed one-dimensional figure, or any of the above plus all the enclosed points. If the enclosed points are included in the base, the cone is a solid object; otherwise it is a two-dimensional object in three-dimensional space. In the case of a solid object, the boundary formed by these lines or partial lines is called the ''lateral surface''; if the lateral surface is unbounded, it is a conical surface. In the case of line segments, the cone does not extend beyond the base, while in the case of half-lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Punji Stick
The punji stick or punji stake is a type of booby trapped stake. It is a simple spike, made out of wood or bamboo, which is sharpened, heated, and usually set in a hole. Punji sticks are usually deployed in substantial numbers. The ''Oxford English Dictionary'' (third edition, 2007) lists less frequent, earlier spellings for "punji stake (or stick)": panja, panjee, panjie, panji, and punge. Description Punji sticks would be placed in areas likely to be passed through by enemy troops. The presence of punji sticks may be camouflaged by natural undergrowth, crops, grass, brush or similar materials. They were often incorporated into various types of traps; for example, a camouflaged pit into which a soldier might fall (it would then be a trou de loup). Sometimes a pit would be dug with punji sticks in the sides pointing ''downward'' at an angle. A soldier stepping into the pit would find it impossible to remove their leg without doing severe damage, and injuries might be incurred by t ...

Wicker
Wicker is the oldest furniture making method known to history, dating as far back as 5,000 years ago. It was first documented in ancient Egypt using pliable plant material, but in modern times it is made from any pliable, easily woven material. The word ''wicker'' or "wisker" is believed to be of Scandinavian origin: , which means "to fold" in Swedish, and meaning willow. Wicker is traditionally made of material of plant origin, such as willow, rattan, reed, and bamboo, but synthetic fibers are now also used. Wicker is light yet sturdy, making it suitable for items that will be moved often like porch and patio furniture. ''Rushwork'' and wickerwork are terms used in England. A typical braiding pattern is called ''Wiener Geflecht'', Viennese Braiding, as it was invented in 18th century Vienna and later most prominently used with the Thonet coffeehouse chair. History Wicker has been documented as far back as ancient Egypt, made from indigenous "reed and swamp grasses." Middle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drowning
Drowning is a type of suffocation induced by the submersion of the mouth and nose in a liquid. Most instances of fatal drowning occur alone or in situations where others present are either unaware of the victim's situation or unable to offer assistance. After successful resuscitation, drowning victims may experience breathing problems, vomiting, confusion, or unconsciousness. Occasionally, victims may not begin experiencing these symptoms until several hours after they are rescued. An incident of drowning can also cause further complications for victims due to low body temperature, aspiration of vomit, or acute respiratory distress syndrome (respiratory failure from lung inflammation.). Drowning is more likely to happen when spending extended periods of time near large bodies of water. Risk factors for drowning include alcohol use, drug use, epilepsy, minimal swim training or a complete lack of training, and, in the case of children, a lack of supervision. Common drowning ...

Julius Caesar
Gaius Julius Caesar (; ; 12 July 100 BC – 15 March 44 BC), was a Roman general and statesman. A member of the First Triumvirate, Caesar led the Roman armies in the Gallic Wars before defeating his political rival Pompey in a civil war, and subsequently became dictator from 49 BC until his assassination in 44 BC. He played a critical role in the events that led to the demise of the Roman Republic and the rise of the Roman Empire. In 60 BC, Caesar, Crassus and Pompey formed the First Triumvirate, an informal political alliance that dominated Roman politics for several years. Their attempts to amass power as were opposed by the within the Roman Senate, among them Cato the Younger with the frequent support of Cicero. Caesar rose to become one of the most powerful politicians in the Roman Republic through a string of military victories in the Gallic Wars, completed by 51 BC, which greatly extended Roman territory. During this time he both invaded Britain and built a b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commentarii De Bello Gallico
''Commentarii de Bello Gallico'' (; en, Commentaries on the Gallic War, italic=yes), also ''Bellum Gallicum'' ( en, Gallic War, italic=yes), is Julius Caesar's firsthand account of the Gallic Wars, written as a third-person narrative. In it Caesar describes the battles and intrigues that took place in the nine years he spent fighting the Celtic and Germanic peoples in Gaul that opposed Roman conquest. The "Gaul" that Caesar refers to is ambiguous, as the term had various connotations in Roman writing and discourse during Caesar's time. Generally, Gaul included all of the regions primarily inhabited by Celts, aside from the province of Gallia Narbonensis (modern-day Provence and Languedoc-Roussillon), which had already been conquered in Caesar's time, therefore encompassing the rest of modern France, Belgium, Western Germany, and parts of Switzerland. As the Roman Republic made inroads deeper into Celtic territory and conquered more land, the definition of "Gaul" shifted. Concu ...

Battle Of Alesia
The Battle of Alesia or Siege of Alesia (September 52 BC) was a military engagement in the Gallic Wars around the Gallic ''oppidum'' (fortified settlement) of Alesia in modern France, a major centre of the Mandubii tribe. It was fought by the Roman army of Julius Caesar against a confederation of Gallic tribes united under the leadership of Vercingetorix of the Arverni. It was the last major engagement between Gauls and Romans, and is considered one of Caesar's greatest military achievements and a classic example of siege warfare and investment; the Roman army built dual lines of fortificationsan inner wall to keep the besieged Gauls in, and an outer wall to keep the Gallic relief force out. The Battle of Alesia marked the end of Gallic independence in the modern day territory of France and Belgium. The battle site was probably atop Mont Auxois, above modern Alise-Sainte-Reine in France, but this location, some have argued, does not fit Caesar's description of the battl ...

Lily
''Lilium'' () is a genus of Herbaceous plant, herbaceous flowering plants growing from bulbs, all with large prominent flowers. They are the true lilies. Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the northern hemisphere and their range is temperate climates and extends into the subtropics. Many other plants have "lily" in their common names, but do not belong to the same genus and are therefore not true lilies. Description Lilies are tall perennial plant, perennials ranging in height from . They form naked or tunicless scaly underground bulbs which are their organs of perennation. In some North American species the base of the bulb develops into rhizomes, on which numerous small bulbs are found. Some species develop stolons. Most bulbs are buried deep in the ground, but a few species form bulbs near the soil surface. Many species form stem-roots. With these, the bulb grows naturally at s ...

Rough Castle
Rough Castle Fort is a Roman fort on the Antonine Wall roughly 2 kilometres south east of Bonnybridge near Tamfourhill in the Falkirk council area, Scotland. It is owned by the National Trust for Scotland. Context The Antonine Wall dates from about 143 AD. The ends of the wall were uncertain for many years. In the east Carriden near Bo'ness on the Forth was a likely endpoint. In the west is Old Kilpatrick on the Clyde, although there were also forts beyond that at Bishopton and Barochan Hill. The fort is one of the best-preserved of the forts constructed along the Wall. Built against the southern rear face of the Wall, the fort was defended by 6 metre thick turf ramparts and surrounded by defensive ditches. Gateways were provided through the main wall to the north, and also through the walls on the other three sides of the fort. Causeways were then constructed across the main Antonine and secondary defensive ditches, affording easy access to and from the fort. The fort w ...
