Abatis
An abatis, abattis, or abbattis is a field fortification consisting of an obstacle formed (in the modern era) of the branches of trees laid in a row, with the sharpened tops directed outwards, towards the enemy. The trees are usually interlaced or tied with wire. Abatis are used alone or in combination with wire entanglements and other obstacles. History Gregory of Tours mentions the use of abatises several times in his writing about the history of the early Franks. He wrote that the Franks ambushed and destroyed a Roman army near Neuss during the reign of Magnus Maximus with the use of an abatis. He also wrote that Mummolus, a general working for Burgundy, successfully used an abatis to defeat a Lombard army near Embrun. Gregory of Tours. A History of the Franks. Pantianos Classics, 1916 A classic use of an abatis was at the Battle of Carillon (1758) during the Seven Years' War. The 3,600 French troops defeated a massive army of 16,000 British and Colonial troops by f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Carillon
The Battle of Carillon, also known as the 1758 Battle of Ticonderoga, was fought on July 8, 1758, during the French and Indian War (which was part of the global Seven Years' War). It was fought near Fort Carillon (now known as Fort Ticonderoga) on the shore of Lake Champlain in the frontier area between the British colony of New York and the French colony of New France. In the battle, which took place primarily on a rise about three-quarters of a mile (one km) from the fort itself, a French army of about 3,600 men under General Marquis de Montcalm and the Chevalier de Levis defeated a numerically superior force of British troops under General James Abercrombie, which frontally assaulted an entrenched French position without using field artillery, a lack that left the British and their allies vulnerable and allowed the French to win a complete victory. The battle was the bloodiest of the American theater of the war, with over 3,000 casualties suffered. French losses w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of The Chateauguay
The Battle of the Chateauguay was an engagement of the War of 1812. On 26 October 1813, a combined British and Canadian force consisting of 1,530 regulars, volunteers, militia and Mohawk warriors from Lower Canada, commanded by Charles de Salaberry, repelled an American force of about 2,600 regulars which was attempting to invade Lower Canada and ultimately attack Montreal. The Battle of the Chateauguay was one of the two battles (the other being the Battle of Crysler's Farm) which caused the Americans to abandon the Saint Lawrence Campaign, their major strategic effort in the autumn of 1813. Prelude American plan Late in 1813, United States Secretary of War John Armstrong devised a plan to capture Montreal, which might have led to the conquest of all Upper Canada. Two divisions were involved. One would descend the St. Lawrence River from Sackett's Harbor on Lake Ontario, while the other would advance north from Plattsburgh on Lake Champlain. The two divisions would unite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wire Entanglement
In the military science of fortification, wire obstacles are defensive obstacles made from barbed wire, barbed tape or concertina wire. They are designed to disrupt, delay and generally slow down an attacking enemy. During the time that the attackers are slowed by the wire obstacle (or possibly deliberately channelled into killing zones, or both) they are easy to target with machine gun and artillery fire. Depending on the requirements and available resources, wire obstacles may range from a simple barbed wire fence in front of a defensive position, to elaborate patterns of fences, concertinas, " dragon's teeth" (which serve a similar purpose as wire obstacles, but for combat vehicles instead) and minefields (both anti-personnel and anti-armor) hundreds of metres thick. One example is "low wire entanglement", which consists of irregularly placed stakes that have been driven into the ground with only some 15 cm (six inches) showing. The barbed wire is then wrapped and tigh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giant Abatis
In folklore, giants (from Ancient Greek: ''gigas'', cognate giga-) are beings of humanoid appearance, but are at times prodigious in size and strength or bear an otherwise notable appearance. The word ''giant'' is first attested in 1297 from Robert of Gloucester's chronicle. It is derived from the ''Gigantes'' () of Greek mythology. Fairy tales such as ''Jack the Giant Killer'' have formed the modern perception of giants as dimwitted and violent ogres, sometimes said to eat humans, while other giants tend to eat livestock. In more recent portrayals, like those of Jonathan Swift and Roald Dahl, some giants are both intelligent and friendly. Literary and cultural analysis Giants appear many times in folklore and myths. Representing the human body enlarged to the point of being monstrous, giants evoke terror and remind humans of their body's frailty and mortality. They are often portrayed as monsters and antagonists, but there are exceptions. Some giants intermingle with human ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fortifications By Type
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 ''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 fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tank
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and battlefield mobility provided by tracks and a powerful engine; their main armament is often mounted within a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large- calibre tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheele ...

Grappling Hook
A grappling hook or grapnel is a device that typically has multiple hooks (known as ''claws'' or ''flukes'') attached to a rope or cable; it is thrown, dropped, sunk, projected, or fastened directly by hand to where at least one hook may catch and hold on to objects. Generally, grappling hooks are used to temporarily secure one end of a rope. They may also be used to dredge for submerged objects. The device was invented by the Romans in approximately 260 BC. The grappling hook was originally used in naval warfare to catch ship rigging so that it could be boarded. Design A common design has a central shaft with a hole ("eye") at the shaft base to attach the rope, and three or four equally spaced hooks at the end, arranged so that at least one is likely to catch on some protuberance of the target. Some modern designs feature folding hooks to resist unwanted attachment. Most grappling hooks are thrown by hand, but some used in rescue work are propelled by compressed air (e.g. ...

Rope
A rope is a group of yarns, Plying, plies, fibres, or strands that are plying, twisted or braided together into a larger and stronger form. Ropes have high tensile strength and can be used for dragging and lifting. Rope is thicker and stronger than similarly constructed cord, String (structure), string, and twine. Construction Rope may be constructed of any long, stringy, fibrous material (e.g., rattan, a natural material), but generally is constructed of certain natural fibre, natural or synthetic fibre, synthetic fibres. Synthetic fibre ropes are significantly stronger than their natural fibre counterparts, they have a higher tensile strength, they are more resistant to rotting than ropes created from natural fibres, and they can be made to float on water. But synthetic ropes also possess certain disadvantages, including slipperiness, and some can be damaged more easily by UV light. Common natural fibres for rope are Manila hemp, hemp, linen, cotton, coir, jute, straw, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire
Fire is the rapid oxidation of a fuel in the exothermic chemical process of combustion, releasing heat, light, and various reaction Product (chemistry), products. Flames, the most visible portion of the fire, are produced in the combustion reaction when the fuel reaches its ignition point temperature. Flames from hydrocarbon fuels consist primarily of carbon dioxide, water vapor, oxygen, and nitrogen. If hot enough, the gases may become ionized to produce Plasma (physics), plasma. The color and Intensity (heat transfer), intensity of the flame depend on the type of fuel and composition of the surrounding gases. Fire, in its most common form, has the potential to result in conflagration, which can lead to permanent physical damage. It directly impacts land-based ecological systems worldwide. The positive effects of fire include stimulating plant growth and maintaining ecological balance. Its negative effects include hazards to life and property, atmospheric pollution, and water ...
