Cannonball
A round shot (also called solid shot or simply ball) is a solid spherical projectile without explosive charge, launched from a gun. Its diameter is slightly less than the bore of the barrel from which it is shot. A round shot fired from a large-caliber gun is also called a cannonball. The cast iron cannonball was introduced by a French artillery engineer Samuel J. Besh after 1450; it had the capacity to reduce traditional English castle wall fortifications to rubble. French armories would cast a tubular cannon body in a single piece, and cannonballs took the shape of a sphere initially made from stone material. Advances in gunpowder manufacturing soon led the replacement of stone cannonballs with cast iron ones. Round shot was made in early times from dressed stone, referred to as gunstone (Middle English: ''gunneston''), but by the 17th century, from iron. It was used as the most accurate projectile that could be fired by a smoothbore cannon, used to batter the w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rifling
In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun's barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting to stabilize the projectile longitudinally by conservation of angular momentum, improving its aerodynamic stability and accuracy over smoothbore designs. Rifling is characterized by its twist rate, which indicates the distance the rifling takes to complete one full revolution, such as "1 turn in 10 inches" (1:10 inches), "1 turn in 254 mm" ("1:254 mm" or "1:25.4 cm)", or the like. Normally, an experienced shooter can infer the units of measurement from the numbers alone. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will rotate at a higher spin rate. The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it – barrel ...

Heated Shot
Heated shot or hot shot is round shot that is heated before firing from muzzle-loading cannons, for the purpose of setting fire to enemy warships, buildings, or equipment. The use of heated shot dates back centuries; it was a powerful weapon against wooden warships, where fire was always a hazard. However, it was rendered obsolete in the mid-19th century when vessels armored with iron replaced wooden warships in the world's navies. Also at around the same time, the replacement of solid-iron shot with exploding shells gave artillery a far more destructive projectile that could be fired immediately without preparation.Roberts, 1863, pg. 107 The use of heated shot was mainly confined to shore batteries and forts, due to the need for a special furnace to heat the shot, and their use from a ship was in fact against Royal Navy regulations because they were so dangerous, although the American ship USS ''Constitution'' had a shot furnace installed for hot shot to be fired from her carron ...

Sabot (firearms)
A sabot (, ) is a supportive device used in firearm/artillery ammunitions to fit/patch around a projectile, such as a bullet/shotgun slug, slug or a flechette-like projectile (such as a kinetic energy penetrator), and keep it aligned in the center of the barrel (firearms), barrel when fired. It allows a narrower projectile with high sectional density to be fired through a gun barrel, barrel of much larger caliber, bore diameter with maximal acceleration, accelerative transfer of kinetic energy. After leaving the muzzle (firearms), muzzle, the sabot typically separates from the projectile in flight, diverting only a very small portion of the overall kinetic energy. The sabot component in projectile design is the relatively thin, tough and deformable seal known as a driving band or obturation ring needed to trap propellant gases behind a projectile, and also keep the projectile centered in the barrel, when the outer shell of the projectile is only slightly smaller in diameter than t ...

Muslim World
The terms Muslim world and Islamic world commonly refer to the Islamic community, which is also known as the Ummah. This consists of all those who adhere to the religious beliefs and laws of Islam or to societies in which Islam is practiced. In a modern geopolitical sense, these terms refer to countries in which Islam is widespread, although there are no agreed criteria for inclusion. The term Muslim-majority countries is an alternative often used for the latter sense. The history of the Muslim world spans about 1,400 years and includes a variety of socio-political developments, as well as advances in the arts, science, medicine, philosophy, law, economics and technology, particularly during the Islamic Golden Age. All Muslims look for guidance to the Quran and believe in the prophetic mission of the Islamic prophet Muhammad, but disagreements on other matters have led to the appearance of different religious schools of thought and sects within Islam. In the modern era, mos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castello Sforzesco
The Castello Sforzesco (Italian for "Sforza's Castle") is a medieval fortification located in Milan, northern Italy. It was built in the 15th century by Francesco Sforza, Duke of Milan, on the remnants of a 14th-century fortification. Later renovated and enlarged, in the 16th and 17th centuries it was one of the largest citadels in Europe. Extensively rebuilt by Luca Beltrami in 1891–1905, it now houses several of the city's museums and art collections. History The original construction was ordered by Galeazzo II Visconti, a local nobleman, in 1358 – c. 1370; this castle was known as the ''Castello di Porta Giova'' (or ''Porta Zubia''), from the name of a gate in walls located nearby. It was built in the same area of the ancient Roman fortification of ''Castrum Portae Jovis'', which served as '' castra pretoria'' when the city was the capital of the Roman Empire. It was enlarged by Galeazzo's successors, Gian Galeazzo, Giovanni Maria and Filippo Maria Visconti, until it beca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Cannon Projectiles
A cannon is any large tubular firearm designed to fire a heavy projectile over a long distance. They were first used in Europe and China, and were the archetypical form of artillery. Round shot and grapeshot were the early projectiles used in cannon. Projectiles fired from cannon ; Round shot or solid shot or a cannonball or simply ball: A solid spherical projectile made, in early times, from dressed stone but, by the 17th century, from iron. The most accurate projectile that could be fired by a smooth-bore cannon, used to batter the wooden hulls of opposing ships, forts, or fixed emplacements, and as a long-range anti-personnel weapon. ; Chain shot or Split shot : Two sub-calibre round shot (a good deal smaller than the bore of the barrel) linked by a length of chain or a solid bar, and used to slash through the rigging and sails of an enemy ship so that it could no longer manoeuver. It was inaccurate and only used at close range. Two-headed bullets (angels) were similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chain Shot
In artillery, chain shot is a type of cannon projectile formed of two sub-calibre balls, or half-balls, chained together. Bar shot is similar, but joined by a solid bar. They were used in the age of sailing ships and black powder cannon to shoot masts, or to cut the shrouds and any other rigging of a target ship. When fired, after leaving the muzzle, the shot's components tumble in the air, and the connecting chain fully extends. In past use, as much as 1.8 m (6 ft) of chain would sweep through the target. However, the tumbling made both bar and chain shot less accurate, so they were used at shorter ranges. Chain shot was sometimes used on land as an anti-personnel load. It was used by the defenders of Magdeburg in May 1631 as an anti-personnel load, which, according to counselor Otto von Guericke, was one reason for the extreme violence of the victorious attackers. It was also used against Parliamentarians in the first English Civil War, and against Cromwell in Irela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carcass (projectile)
A carcass was an early form of Incendiary ammunition, incendiary bomb or shell (projectile), shell, intended to set targets on fire. It comprised an external casing, usually of cast iron, filled with a highly flammable mixture, and having three to five holes through which the burning filling could blaze outward."Carcass". ''Oxford English Dictionary''. Oxford University Press. 2nd edition. 1989. Carcasses were shot from howitzers, Mortar (weapon), mortars, and other cannons to set fire to buildings and defence (military), defences; on impact, the shell shattered, spreading its incendiary filling around the target. Congreve rockets were also sometimes fitted with carcass heads. They were named ''carcass'' because the circles which pass from one ring, or plate, to the other, were thought to resemble the ribs of a human Cadaver, carcass. History Carcasses were used for the first time by the French and Münsterite troops under Louis XIV of France, Louis XIV and Bernard von Galen in 167 ...

Battle Of Bosworth
The Battle of Bosworth or Bosworth Field was the last significant battle of the Wars of the Roses, the civil war between the houses of Lancaster and York that extended across England in the latter half of the 15th century. Fought on 22 August 1485, the battle was won by an alliance of Lancastrians and disaffected Yorkists. Their leader Henry Tudor, Earl of Richmond, became the first English monarch of the Tudor dynasty by his victory and subsequent marriage to a Yorkist princess. His opponent Richard III, the last king of the House of York, was killed during the battle, the last English monarch to die in combat. Historians consider Bosworth Field to mark the end of the Plantagenet dynasty, making it one of the defining moments of English history. Richard's reign began in 1483 when he seized the throne from his twelve-year-old nephew Edward V. The boy and his younger brother Richard soon disappeared, to the consternation of many, and Richard's support was further eroded by ...
