Mortar (artillery)
A mortar is usually a simple, lightweight, man-portable, muzzle-loaded weapon, consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. They launch explosive shells (technically called bombs) in high-arcing ballistic trajectories. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. History Mortars have been used for hundreds of years. The earliest mortars were used 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. Choi Hae-san (최해산, 崔海山) (1380–1443), the son of Choe Mu-seon (최무선, 崔茂宣) (1325–1395), is generally credited with inventing the ''wan'gu''. In the Ming dynasty, general Qi Jiguang recorded the use of a mini cannon called the Hu dun pao that was simi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mehmed The Conqueror
Mehmed II ( ota, محمد ثانى, translit=Meḥmed-i s̱ānī; tr, II. Mehmed, ; 30 March 14323 May 1481), commonly known as Mehmed the Conqueror ( ota, ابو الفتح, Ebū'l-fetḥ, lit=the Father of Conquest, links=no; tr, Fâtih Sultan Mehmed, links=no), was an Ottoman sultan who ruled from August 1444 to September 1446, and then later from February 1451 to May 1481. In Mehmed II's first reign, he defeated the crusade led by John Hunyadi after the Hungarian incursions into his country broke the conditions of the truce Peace of Szeged. When Mehmed II ascended the throne again in 1451, he strengthened the Ottoman navy and made preparations to attack Constantinople. At the age of 21, he conquered Constantinople (modern-day Istanbul) and brought an end to the Byzantine Empire. After the conquest Mehmed claimed the title Caesar of the Roman Empire ( ota, قیصر روم, Qayser-i Rûm, links=no), based on the fact that Constantinople had been the seat and capital of ...

Parthenon
The Parthenon (; grc, Παρθενών, , ; ell, Παρθενώνας, , ) is a former temple on the Athenian Acropolis, Greece, that was dedicated to the goddess Athena during the fifth century BC. Its decorative sculptures are considered some of the high points of Greek art, an enduring symbol of Ancient Greece, democracy and Western civilization. The Parthenon was built in thanksgiving for the Hellenic victory over Persian invaders during the Greco-Persian Wars. Like most Greek temples, the Parthenon also served as the city treasury. Construction started in 447 BC when the Delian League was at the peak of its power. It was completed in 438; work on the decoration continued until 432. For a time, it served as the treasury of the Delian League, which later became the Athenian Empire. In the final decade of the 6th century AD, the Parthenon was converted into a Christian church dedicated to the Virgin Mary. After the Ottoman conquest in the mid-fifteenth century ...

Ammunition Depot
An ammunition dump, ammunition supply point (ASP), ammunition handling area (AHA) or ammunition depot is a military storage facility for live ammunition and explosives. The storage of live ammunition and explosives is inherently hazardous. There is the potential for accidents in the unloading, packing, and transfer of ammunition. Great care is taken in handling these dangerous explosives so as not to harm personnel or nearby ammunition. Despite the intensive preventive measures they get, ammunition depots around the world suffer from non-combat fires and explosions. Although this is a rare occurrence, there are devastating consequences when it does happen. Usually, an ammunition depot experiencing even minor explosions in one of its sites/buildings is immediately evacuated together with surrounding civilian areas. Thus, all of the stored ammunition is left to detonate itself completely for days or weeks, with very limited attempts at firefighting from a safe distance.How one c ...

Morea
The Morea ( el, Μορέας or ) was the name of the Peloponnese peninsula in southern Greece during the Middle Ages and the early modern period. The name was used for the Byzantine province known as the Despotate of the Morea, by the Ottoman Empire for the Morea Eyalet, and later by the Republic of Venice for the short-lived Kingdom of the Morea. Etymology There is some uncertainty over the origin of the medieval name "Morea", which is first recorded only in the 10th century in the Byzantine chronicles. Traditionally, scholars thought the name to have originated from the word ''morea'' (μορέα), meaning morus or mulberry, a tree which, though known in the region from the ancient times, gained value after the 6th century, when mulberry-eating silkworms were smuggled from China to Byzantium. The British Byzantinist Steven Runciman suggested that the name comes "from the likeness of its shape to that of a mulberry leaf". History After the conquest of Constantinople by t ...

Bomb Vessel
A bomb vessel, bomb ship, bomb ketch, or simply bomb was a type of wooden sailing naval ship. Its primary armament was not cannons ( long guns or carronades) – although bomb vessels carried a few cannons for self-defence – but mortars mounted forward near the bow and elevated to a high angle, and projecting their fire in a ballistic arc. Explosive shells (also called ''bombs'' at the time) or carcasses were employed rather than solid shot. Bomb vessels were specialized ships designed for bombarding (hence the name) fixed positions on land. In the 20th century, this naval gunfire support role was carried out by the most similar purpose-built World War I- and II-era monitors, but also battleships, cruisers, and destroyers. Development The first recorded deployment of bomb vessels by the English was for the siege of Calais in 1347 when Edward III deployed single deck ships with bombardes and other artillery. The first specialised bomb vessels were built towards the end ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coehorn
A Coehorn (also spelled ''cohorn'') is a lightweight mortar originally designed by Dutch military engineer Menno van Coehoorn. Concept and design Van Coehoorn came to prominence during the 1688–97 Nine Years War, whose tactics have been summarised by historian John Childs as follows: "The majority of infantrymen never fired their muskets in anger;....armies were consciously geared towards the dominant forms of warfare; manoeuvre and the siege." This emphasis on siege warfare saw many developments in the use and design of artillery. Fortifications were vulnerable to vertical trajectory or plunging fire, and the concept of mortars was well understood, but large scale mortars were commonly used initially to provide close support for infantry assaults on fortified positions. Van Coehoorn demonstrated them in May 1701 to William III of England, and they were first used in action at the siege of Kaiserswerth in 1702. The original was light enough to be moved by as few as two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuse (explosives)
In an explosive, pyrotechnics, pyrotechnic device, or military munition, a fuse (or fuze) is the part of the device that initiates function. In common usage, the word fuse is used indiscriminately. However, when being specific (and in particular in a military context), the term ''fuse'' describes a simple pyrotechnic initiating device, like the cord on a firecracker whereas the term ''fuze'' is used when referring to a more sophisticated ignition device incorporating mechanical and/or electronics, electronic components, such as a proximity fuze for an M107 projectile, M107 artillery shell, magnetometer, magnetic or acoustic signature, acoustic fuze on a sea mine, spring-loaded grenade fuze, pencil detonator, or anti-handling device. History Documented evidence suggests that the earliest fuses were first used by the Song Chinese between the 10th and 12th centuries. After the Chinese invented gunpowder, they began adapting its explosive properties for use in military technology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Menno Van Coehoorn
Menno, Baron van Coehoorn (; March 1641 – 17 March 1704) was a Dutch soldier and engineer, regarded as one of the most significant figures in Dutch military history. In an era when siege warfare dominated military campaigns, he and his French counterpart Vauban were the acknowledged experts in designing, taking and defending fortifications. Both had their advocates; Vauban's maxim of 'more powder, less blood' also took longer, an important consideration when most military deaths occurred from disease. He is also viewed as more innovative in the design and extent of his fortifications, which included ports, waterways, roads and even town layouts. However, unlike Vauban, Van Coehoorn had limited financial resources. He showed great skill in maximising these, while adapting to the specific challenges posed by the flat terrain in the Netherlands. Some of his water defences and designs were still being used in the 1950s. Life Van Coehoorn was born at Britsum in March 1641, one o ...

Mortar And Pestle
Mortar and pestle is a set of two simple tools used from the Stone Age to the present day to prepare ingredients or substances by crushing and grinding them into a fine paste or powder in the kitchen, laboratory, and pharmacy. The ''mortar'' () is characteristically a bowl, typically made of hard wood, metal, ceramic, or hard stone such as granite. The ''pestle'' (, also ) is a blunt, club-shaped object. The substance to be ground, which may be wet or dry, is placed in the mortar where the pestle is pounded, pressed, and rotated into the substance until the desired texture is achieved. Mortars and pestles have been used in cooking since prehistory; today they are typically associated with the profession of pharmacy due to their historical use in preparing medicines. They are used in chemistry settings for pulverizing small amounts of chemicals; in arts and cosmetics for pulverizing pigments, binders, and other substances; in ceramics for making grog; in masonry and in other typ ...

Pumhart Von Steyr
The Pumhart von Steyr is a medieval large-calibre cannon from Styria, Austria, and the largest known wrought-iron bombard by caliber. It weighs around 8 tons and has a length of more than 2.5 meters. It was produced in the early 15th century and could fire, according to modern calculations, an 80 cm stone ball weighing 690 kg to a distance of roughly 600 m after being loaded with 15 kg of gunpowder and set at an elevation of 10°. The bombard is today on display in one of the artillery halls of the Heeresgeschichtliches Museum at Vienna. Besides the Pumhart von Steyr, a number of 15th-century European large-calibre weapons are known to have been employed primarily in siege warfare, including the wrought-iron Mons Meg and Dulle Griet as well as the cast-bronze Faule Mette, Faule Grete and Grose Bochse.
