Mortier De 270 Mm Modèle 1885
The Mortier de 270 mm modèle 1885 was a French Mortar (weapon), heavy mortar employed as siege artillery during the First World War. History The Mortier de 270 mm G mle 1885 was one of a series of heavy artillery pieces designed by Charles Ragon de Bange, Colonel Charles Ragon de Bange. On 11 May 1874 three de Bange heavy cannons (Canon de 120 mm modèle 1878, 120 mm, De Bange 155 mm cannon, 155 mm, Canon de 240 L Mle 1884, 240 mm) and two mortars (Mortier de 220 mm modèle 1880, 220 mm, 270 mm) were ordered by the French Army in World War I, French Army. The mle 1885 was advanced for its time due to being built completely of steel instead of a steel liner and cast iron reinforcing Hoop gun, hoops of the previous ''Canon de 240 mm C mle 1870''-87. The later Mortier de 270 mm modèle 1889, Mortier de 270 mm modèle 1889 was based on the mle 1885 and adapted to the coastal artillery role by fitting the same barrel to a different carriage.

Mortar (weapon)
A mortar today is usually a simple, lightweight, man-portable, Muzzleloader, muzzle-loaded cannon, consisting of a Smoothbore, smooth-bore (although some models use a Rifling, rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a Sight (device), sight. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. Historically mortars were heavy Siege, siege artillery. Mortars launch explosive shell (projectile), shells (technically called Bomb, bombs) in high arching Projectile motion, ballistic trajectories. History Mortars have been used for hundreds of years. The earliest reported use of mortars was in Korea in a 1413 naval battle when Korean gunsmiths developed the ''wan'gu'' (gourd-shaped mortar) (완구, 碗口). The earliest version of the ''wan'gu'' dates back to 1407. Ch'oe Hae-san (1380–1443), the son of Ch'oe Mu-sŏn (1325–1395), is generally credited with inventi ...

World War I Artillery Of France
The world is the totality of entities, the whole of reality, or everything that exists. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique, while others talk of a "plurality of worlds". Some treat the world as one simple object, while others analyze the world as a complex made up of parts. In scientific cosmology, the world or universe is commonly defined as "the totality of all space and time; all that is, has been, and will be". Theories of modality talk of possible worlds as complete and consistent ways how things could have been. Phenomenology, starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon, or the "horizon of all horizons". In philosophy of mind, the world is contrasted with the mind as that which is represented by the mind. Theology conceptualizes the world in relation to God, for example, as God's creation, ...

Artillery Of France
Artillery consists of ranged weapons that launch munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons were developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower. Originally, the word "artillery" referred to any group of soldiers primarily armed with some form of manufactured weapon or armour. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannon, and in contemporary usage, usually refers to shell-firing guns, howitzers, and mortars (collectively called ''barrel artillery'', ''cannon artillery'' or ''gun artillery'') and rocket artillery. In common ...

24 Cm Mörser M 98
The 24 cm Mörser M 98 was a heavy siege howitzer used by Austria-Hungary during World War I. It was designed to attack modern fortifications, but its short range and ineffective ammunition led to the development of the 30.5 cm Mörser M 11 and M 16. History Based on a Krupp 1888–1890 design, Škoda Works developed a new heavy mortar on a middle pivot mounting for testing in 1896. However, the authorities realised that advancing technology required a newer design using a barrel in a cradle mounted on a hydraulic recoil system. While introduced in November 1900, it wasn't quite ready and went through a number of minor improvements. One major problem was weak recoil springs that would allow the barrel to slip out of its cradle while elevated. Leather and horsehair stoppers could be wedged in the cradle as a short-term fix. But the permanent fix had to wait until the M 98/7 version that extended the jacket surrounding the barrel to the muzzle and redesigned the cradle was pro ...

28 Cm Haubitze L/12
The 28 cm Haubitze L/12 was a German coastal defense and siege howitzer. Developed by Krupp before World War I that saw service in both World War I and World War II. Description The ''28 cm Haubitze L/12 in Mittelpivotlafette C/92'' was a design of the late 19th century initially intended for coastal defense. The theory of operation was a low-velocity howitzer firing a large shell at a high angle was more likely to destroy an enemy ship by penetrating its thin deck armor than a high-velocity low-angle gun attempting to penetrate its thicker belt armor. The downside was that high-angle fire was harder to aim correctly so more howitzers would be needed to defend an area from attack. However, if the area was constrained by geography like a port at the mouth of a river the navigation channels could be measured ahead of time and firing ranges calculated. A complicating factor was as naval artillery progressed their size and range soon eclipsed its range. In the coastal defe ...

28 Cm Howitzer L/10
The was a Imperial Japanese Army, Japanese Coastal artillery, coastal and siege engine, siege howitzer. It was developed by Armstrong Whitworth, Armstrong before 1892 and saw service in the Russo-Japanese War during the siege of Port Arthur and the Second Sino-Japanese War. Design and description The 28 cm Howitzer L/10 was designed in 1884 by the British Armstrong Whitworth, Armstrong company. Armstrong had an Italian subsidiary which produced guns for the Italian Navy and Major Pompeo Grillo, a heavy artillery specialist was hired in April 1884 to help the construction of artillery at a new plant in Osaka. The description from Brassey's Naval Annual of 1892 reads "The howitzer was a 28-cm rifled breech-loader of cast iron, 9 calibres long made at Osaka, from the designs of guns made for the Italians by Sir W. G. Armstrong Whitworth & Co, Sir W.G. Armstrong". The Italians produced the design in a number of different lengths and they were designated by their diameter and l ...

Block And Tackle
A block and tackle or only tackle is a system of two or more pulleys with a rope or cable threaded between them, used to provide tension and lift heavy loads. The pulleys are assembled to form blocks and then blocks are paired so that one is fixed and one moves with the load. The rope is threaded through the pulleys to provide mechanical advantage that amplifies the force applied to the rope. Hero of Alexandria described cranes formed from assemblies of pulleys in the first century. Illustrated versions of Hero's ''Mechanica'' (a book on raising heavy weights) show early block and tackle systems. Overview A block is a set of pulleys or sheaves mounted on a single frame. An assembly of blocks with a rope threaded through the pulleys is called tackle. The process of threading ropes or cables through blocks is called "reeving", and a threaded block and tackle is said to have been "rove". A block and tackle system amplifies the tension force in the rope to lift heavy loads ...

Trunnion
A trunnion () is a cylinder, cylindrical Boss (engineering), protrusion used as a mounting or pivoting point. First associated with cannons, they are an important military development. In mechanical engineering (see the Trunnion#Trunnion bearings, trunnion bearing section below), it is one part of a rotating joint where a shaft (the trunnion) is inserted into (and turns inside) a full or partial cylinder. Medieval history In a cannon, the trunnions are two projections cast just forward of the center of mass of the cannon and fixed to a two-wheeled movable gun carriage. With the creation of larger and more powerful siege guns in the early 15th century, a new way of mounting them became necessary. Stouter gun carriages were created with reinforced wheels, axles, and “trails” which extended behind the gun. Guns were now as long as in length and they were capable of shooting iron projectiles weighing from . When discharged, these wrought iron balls were comparable in range ...

Breech Loaded
A breechloader is a firearm in which the user loads the ammunition from the breech end of the barrel (i.e., from the rearward, open end of the gun's barrel), as opposed to a muzzleloader, in which the user loads the ammunition from the ( muzzle) end of the barrel. The vast majority of modern firearms are generally breech-loaders, while firearms made before the mid-19th century were mostly smoothbore muzzle-loaders. Only a few muzzleloading weapons, such as mortars, rifle grenades, some rocket launchers, such as the Panzerfaust 3 and RPG-7, and the GP series grenade launchers, have remained in common usage in modern military conflicts. However, referring to a weapon explicitly as breech-loading is mostly limited to weapons where the operator loads ammunition by hand (and not by operating a mechanism such as a bolt-action), such as artillery pieces or break-action small arms. Breech-loading provides the advantage of reduced reloading time because it is far quicker to load the ...

Trench Warfare
Trench warfare is a type of land warfare using occupied lines largely comprising Trench#Military engineering, military trenches, in which combatants are well-protected from the enemy's small arms fire and are substantially sheltered from artillery. It became archetypically associated with World War I (1914–1918), when the Race to the Sea rapidly expanded trench use on the Western Front (World War I), Western Front starting in September 1914.. Trench warfare proliferated when a Weapons of World War I, revolution in firepower was not matched by similar advances in mobility (military), mobility, resulting in a grueling form of warfare in which the defender held the advantage. On the Western Front in 1914–1918, both sides constructed elaborate trench, underground, and dugout (shelter), dugout systems opposing each other along a front (military), front, protected from assault by barbed wire. The area between opposing trench lines (known as "no man's land") was fully exposed ...

Western Front (World War I)
The Western Front was one of the main Theatre (warfare), theatres of war during World War I. Following the outbreak of war in August 1914, the Imperial German Army, German Army opened the Western Front by German invasion of Belgium (1914), invading Luxembourg and Belgium, then gaining military control of important industrial regions in Third Republic of France, France. The German advance was halted with the First Battle of the Marne, Battle of the Marne. Following the Race to the Sea, both sides dug in along a meandering line of fortified trench warfare, trenches, stretching from the North Sea to the Swiss frontier with France, the position of which changed little except during early 1917 and again in 1918. Between 1915 and 1917 there were several offensives along this Front (military), front. The attacks employed massive artillery bombardments and massed infantry advances. Entrenchments, machine gun emplacements, barbed wire, and artillery repeatedly inflicted severe casualties ...
