Fascine
A fascine (pronounced ) is a rough bundle of wikt:brushwood, brushwood or other material used for strengthening an earthen structure, or making a path across uneven or wet terrain. Typical uses are protecting the banks of streams from erosion (a fascine mattress), covering Marsh, marshland, or providing Geotechnical engineering, ground improvement in a manner similar to that of modern Geotextile, geotextiles. In war they have often been used to help armiesin modern times, especially tanks and other vehiclescross trenches, valleys, marshes, muddy or uneven terrain, etc. Early military use Fascine bundles were used defensively for Revetment, revetting (shoring up) trenches or ramparts, especially around artillery batteries, or offensively to fill in ditches and to cross obstacles on a battlefield. Fascine bridges, a regularly attested feature of Roman military engineering, would have been widespread in the ancient world due to their usefulness and ease of construction. During th ...

Fascine Mattress
A fascine mattress , literally sink piece), is a large woven mat made of wikt:brushwood, brushwood, typically willow twigs and shoot (botany), shoots, used to protect riverbeds and other underwater surfaces from Hydrodynamic scour, scour and erosion. They are similar in construction to a fascine, but are primarily used for hydraulic engineering works, typically to strengthen the banks of rivers and streams, as well as coastal structures like revetments and groynes. Modern fascine mattresses utilise a layer of geotextile in order to fulfill the competing requirements of water Permeability (Earth sciences), permeability balanced with the need to be impervious to sand. Prior to the advent of synthetic geotextiles in the 1960s, a layer formed from Reed (plant), reeds was incorporated to make the fascine mattress sand-tight. Fascine mattresses have been used worldwide, but are particularly common in The Netherlands, where significant expertise in their preparation and construction i ...

Battle Of Narva (1700)
The Battle of Narva (, ; ) on (20 November in the Swedish calendar, Swedish transitional calendar) was an early battle in the Great Northern War. A Sweden, Swedish relief army under Charles XII of Sweden defeated a Tsardom of Russia, Russian siege force three to four times its size. Previously, Charles XII had forced Denmark–Norway to sign the Treaty of Travendal. Narva was not followed by further advances of the Swedish army into Russia; instead, Charles XII turned southward to expel August the Strong from Livonia and Polish–Lithuanian Commonwealth, Poland–Lithuania. Tsar Peter the Great of Russia took Narva in a Battle of Narva (1704), second battle in 1704. Background During the 17th century, Tsardom of Russia, Russia was less advanced technologically than the rest of Europe, a condition which extended to its armed forces.Peter The Great – Swift Despite this shortcoming, Peter the Great of Russia was keen to get "an adequate opening to the Baltic" by conquering pa ...

Billhook
A billhook or bill hook is a versatile cutting tool used widely in agriculture and forestry for cutting woody material such as shrubs, small trees and branches. It is distinct from the sickle. It was commonly used in Europe with an important variety of traditional local patterns. Elsewhere, it was also developed locally such as in the Indian subcontinent, or introduced regionally as in the Americas, South Africa, and Oceania by European settlers. Design The blade is usually made from a medium-carbon steel in varying weights and lengths, but typically long. Blades are straight near the handle but have an increasingly strong curve towards the end. The blade is generally sharpened only on the inside of the curve, but double-edged billhooks, or "broom hooks", also have a straight secondary edge on the back. The blade is fixed to a wooden handle, in Europe usually made from Fraxinus excelsior, ash due to its strength and ability to deal with repeated impact. Handles are mostly ...

Revetment
A revetment in stream restoration, river engineering or coastal engineering is a facing of impact-resistant material (such as stone, concrete, sandbags, or wooden piles) applied to a bank or wall in order to absorb the energy of incoming water and protect it from erosion. River or coastal revetments are usually built to preserve the existing uses of the shoreline and to protect the slope. In architecture generally, it means a retaining wall. In military engineering it is a structure formed to secure an area from artillery, bombing, or stored explosives. Freshwater revetments Many revetments are used to line the banks of freshwater rivers, lakes, and man-made reservoirs, especially to prevent damage during periods of floods or heavy seasonal rains (see riprap). Many materials may be used: wooden piles, loose-piled boulders or concrete shapes, or more solid banks. Concrete revetments are the most common type of infrastructure used to control the Mississippi River. More than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Churchill Tank
The Tank, Infantry, Mk IV (A22) Churchill was a British infantry tank used in the Second World War, best known for its heavy armour, large longitudinal chassis with all-around tracks with multiple Bogie#Tracked vehicles, bogies, its ability to climb Grade (slope), steep slopes, and its use as the basis of many specialist vehicles. It was one of the heaviest Allies of World War II, Allied tanks of the war. The origins of the Churchill's design lay in the expectation that war in Europe might be fought in conditions similar to those of the First World War, and thus emphasised the ability to cross difficult ground. The Churchill was hurried into production in order to build up British defences against a possible German invasion. The first vehicles had flaws that had to be overcome before the Churchill was accepted for wide use. After several Mark (designation), marks (versions) had been built, a better-armoured specification, the Mark VII, entered service with the British Army. The ...

Tanks In World War I
A tank is an armoured fighting vehicle intended as a primary offensive weapon in Front line, front-line Land warfare, ground combat. Tank designs are a balance of heavy firepower, strong Vehicle armour, armour, and battlefield Mobility (military), mobility provided by Continuous track, tracks and a powerful engine; their main armament is often mounted within a Gun turret, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles XII Of Sweden
Charles XII, sometimes Carl XII () or Carolus Rex (17 June 1682 – 30 November 1718 O.S.), was King of Sweden from 1697 to 1718. He belonged to the House of Palatinate-Zweibrücken, a branch line of the House of Wittelsbach. Charles was the only surviving son of Charles XI and Ulrika Eleonora the Elder. He assumed power, after a seven-month caretaker government, at the age of fifteen. In 1700, a triple alliance of Denmark–Norway, Saxony– Poland–Lithuania and Russia launched a threefold attack on the Swedish protectorate of Holstein-Gottorp and provinces of Livonia and Ingria, aiming to take advantage of the Swedish Empire being unaligned and ruled by a young and inexperienced king, thus initiating the Great Northern War. Leading the Swedish army against the alliance, Charles won multiple victories despite being significantly outnumbered. A major victory over a much larger Russian army in 1700, at the Battle of Narva, compelled Peter the Great to sue for peace, an offe ...

Gabion
A gabion (from Italian ''gabbione'' meaning "big cage"; from Italian ''gabbia'' and Latin ''cavea'' meaning "cage") is a cage, cylinder or box filled with rocks, concrete, or sometimes sand and soil for use in civil engineering, road building, military applications and landscaping. For erosion control, caged riprap is used. For dams or in foundation construction, cylindrical metal structures are used. In a military context, earth- or sand-filled gabions are used to protect sappers, infantry, and artillerymen from enemy fire. Leonardo da Vinci designed a type of gabion called a ''Corbeille Leonard'' ("Leonard basket") for the foundations of the San Marco Castle in Milan. Civil engineering The most common civil engineering use of gabions was refined and patented by Gaetano Maccaferri in the late 19th century in Sacerno, Emilia Romagna and used to stabilize shorelines, stream banks or slopes against erosion. Other uses include retaining walls, noise barriers, temporary fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Khalkhin Gol
The Battles of Khalkhin Gol (; ) were the decisive engagements of the undeclared Soviet–Japanese border conflicts involving the Soviet Union, Mongolia, Japan and Manchukuo in 1939. The conflict was named after the river Khalkhin Gol, which passes through the battlefield. In Japan, the decisive battle of the conflict is known as the after Nomonhan Burd Obo, an ''obo'', a cairn set as a border marker in the Yongzheng period of the Qing dynasty. The battles resulted in the defeat of the Japanese Sixth Army. Background After the Japanese occupation of Manchuria in 1931, Japan turned its military interests to Soviet territories that bordered those areas. Meanwhile, the Soviet Union and the People's Republic of Mongolia signed an Mutual Assistance Pact in March 1936, allowing the former to send troops to Mongolia. In the same year, Japan signed the Anti-Comintern Pact in response. Following Japan's full invasion of China in July 1937, the Soviet Union sent the 57th Special ...
