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. In Slavic languages it is known as ''zaseka'', a position behind sharpened objects. History There is evidence it was used as early as the Roman Imperial period, and as recently as the American Civil War and the Anglo-Zulu War of 1879. 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 fronting their defensive positions with an extremely dense abatis. The British found the defences almost impossible to breach and were forced to withdraw with some 2,600 casualties. Other uses of an abatis can be found ...

Battle Of Carillon
The Battle of Carillon, also known as the 1758 Battle of Ticonderoga, Chartrand (2000), p. 57 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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Zasechnaya Cherta
Zasechnaya cherta (russian: Большая засечная черта, loosely translated as Great Abatis Line or Great Abatis Border) was a chain of fortification lines, created by Grand Duchy of Moscow and later the Tsardom of Russia to protect it from the Crimean-Nogai Raids that ravaged the southern provinces of the country via the Muravsky Trail during the Russo-Crimean Wars. It was south of the original line along the Oka River. It also served as a border between the Muscovite State and the steppe nomads. As a fortification line stretching for hundreds of kilometers, the Great Abatis Border is analogous to the Great Wall of China and the Roman limes. Abatis is a military term for a field fortification made by cutting down trees. The line was built from the felled trees that were arranged as a barricade. It was also fortified by ditches and earth mounds, palisades, watch towers and natural features like lakes and swamps. The width of the abatis mounts up to several hundre ...

Battle Of The Chateauguay
The Battle of the Chateauguay was an engagement of the War of 1812. On 26 October 1813, a combined United Kingdom, British and British North America, Canadian force consisting of 1,530 regulars, volunteers, militia and Mohawk people, Mohawk warriors from Lower Canada, commanded by Charles de Salaberry, repelled an United States, 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 Jr., 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, New York, Sackett's Harbor on Lak ...

Barbed Wire
A close-up view of a barbed wire Roll of modern agricultural barbed wire Barbed wire, also known as barb wire, is a type of steel fencing wire constructed with sharp edges or points arranged at intervals along the strands. Its primary use is the construction of inexpensive fences, and it is also used as a security measure atop walls surrounding property. As a wire obstacle, it is a major feature of the fortifications in trench warfare. A person or animal trying to pass through or over barbed wire will suffer discomfort and possibly injury. Barbed wire fencing requires only fence posts, wire, and fixing devices such as staples. It is simple to construct and quick to erect, even by an unskilled person. The first patent in the United States for barbed wire was issued in 1867 to Lucien B. Smith of Kent, Ohio, who is regarded as the inventor. Joseph F. Glidden of DeKalb, Illinois, received a patent for the modern invention in 1874 after he made his own modifications to previous ...

United States Marine Corps
The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, artillery, aerial, and special operations forces. The U.S. Marine Corps is one of the eight uniformed services of the United States. The Marine Corps has been part of the U.S. Department of the Navy since 30 June 1834 with its sister service, the United States Navy. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers. The history of the Marine Corps began when two battalions of Continental Marines were formed on 10 November 1775 in Philadelphia ...

United States Army
The United States Army (USA) is the land service branch of the United States Armed Forces. It is one of the eight U.S. uniformed services, and is designated as the Army of the United States in the U.S. Constitution.Article II, section 2, clause 1 of the United States Constitution (1789). See alsTitle 10, Subtitle B, Chapter 301, Section 3001 The oldest and most senior branch of the U.S. military in order of precedence, the modern U.S. Army has its roots in the Continental Army, which was formed 14 June 1775 to fight the American Revolutionary War (1775–1783)—before the United States was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.Library of CongressJournals of the Continental Congress, Volume 27/ref> The United States Army considers itself to be a continuation of the Continental Army, and thus considers its institutional inception to b ...

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 good battlefield mobility provided by tracks and a powerful engine; usually their main armament is mounted in 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- caliber 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 whe ...

Wire Obstacle
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] |
Grappling Hook
A grappling hook or grapnel is a device that typically has multiple hooks (known as ''claws'' or ''flukes'') attached to a rope; it is thrown, dropped, sunk, projected, or fastened directly by hand to where at least one hook may catch and hold onto 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., the Plu ...
