Cannon Operation
Cannon operation required specialised crew and gunners, who were first enlisted by the Spanish in the 14th century.Hoffmeyer, p. 217. The nature of cannon operation often depended on the size of the cannon and whether they were breech-loading or muzzle-loading. English cannons of the late 14th century became mobile, while the largest cannon (such as the heavy siege cannon of the Ottoman Turks or the Jaivana cannon of India) required huge crews to transport and operate them. As the "giant gun" trend disappeared in Europe, in favour of lighter, more manoeuvrable pieces in larger numbers, cannon operating crews became smaller, heralding the early use of true field artillery. While the medieval Dardanelles Gun had required 200 men just to operate it, an 18th-century English cannon required only a dozen men, including two gunners, while during the Napoleonic Wars five gunners were used.Holmes, ''Redcoat British Soldier in the age of Horse and Musket'' Overview Cannon operation is ...

Cannon
A cannon is a large- caliber gun classified as a type of artillery, which usually launches a projectile using explosive chemical propellant. Gunpowder ("black powder") was the primary propellant before the invention of smokeless powder during the late 19th century. Cannons vary in gauge, effective range, mobility, rate of fire, angle of fire and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. A cannon is a type of heavy artillery weapon. The word ''cannon'' is derived from several languages, in which the original definition can usually be translated as ''tube'', ''cane'', or ''reed''. In the modern era, the term ''cannon'' has fallen into decline, replaced by ''guns'' or ''artillery'', if not a more specific term such as howitzer or mortar, except for high-caliber automatic weapons firing bigger rounds than machine guns, called autocannons. The earliest known depict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Touch Hole
A touch hole, also called a vent, is a small hole at the rear (breech) portion of the barrel of a muzzleloading gun or cannon. The hole provides external access of an ignition spark (fire), spark into the breech chamber of the barrel (where the combustion of the propellant occurs), either with a slow match (matchlock), a linstock or a flash pan ignited by some type of pyrite- (wheellock) or flint-based lock (firearm), gunlock (snaplock, snaphaunce and flintlock mechanism, flintlock), which will initiate the combustion of the main gunpowder explosive charge, charge. Without touch hole, it would be nearly impossible to ignite the powder because the only otherwise access into the barrel is from the front via the muzzle (firearms), muzzle, which is obturated by the projectile. In the later caplock firearms, the ignition sparks are generated by a shock sensitivity, shock-sensitive percussion cap placed over a conical "nipple", which has a hollow pipe (fluid conveyance), conduit known ...

Sulfur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the production o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assault Pioneer
An Assault Pioneer is an infantry soldier who is responsible for: * The construction of tools for infantry soldiers to cross natural and man-made obstacles as well as breaching of enemy fortifications; * Supervising the construction of field defensive works such as bunkers, support weapon firing positions, etc.,; * The use of demolitions, land mines and booby traps, as well as their clearance; and * Performing of all other normal infantry duties as the situation requires Assault Pioneers are lineal descendants of the Pioneers who have formed an essential part of armies since at least the time of the Roman legions. These pioneers were normally employed to march in front of the advancing army, clearing the route as necessary. They could also construct defenses and bivouac facilities. More recently (since the Second World War) assault pioneers have normally formed a Platoon in infantry battalions, and such platoons can be found in a number of British Army and Commonwealth infantry ...

Matross
A matross was a soldier of artillery, who ranked next below a gunner. The duty of a matross was to assist the gunners in loading, firing and sponging the guns. They were provided with firelocks, and marched with thstore-wagons acting as guards. In the United States Army, a matross ranked as a private of artillery. The word is probably derived from French ''matelot'', a sailor. The OED states that the word is borrowed from the Dutch ''Matroos'' ('a sailor of the lowest rank'), and is cognate with similar terms in German, Danish and Swedish. at Oxford English Dictionary

Iron
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bronze
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals, such as phosphorus, or metalloids such as arsenic or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as ultimate tensile strength, strength, ductility, or machinability. The three-age system, archaeological period in which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia and India is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age starting from about 1300 BCE and reaching most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in mod ...

Battle Of Crécy
The Battle of Crécy took place on 26 August 1346 in northern France between a French army commanded by King PhilipVI and an English army led by King EdwardIII. The French attacked the English while they were traversing northern France during the Hundred Years' War, resulting in an English victory and heavy loss of life among the French. The English army had landed in the Cotentin Peninsula on 12 July. It had burnt a path of destruction through some of the richest lands in France to within 2 miles (3 km) of Paris, sacking many towns on the way. The English then marched north, hoping to link up with an allied Flemish army which had invaded from Flanders. Hearing that the Flemish had turned back, and having temporarily outdistanced the pursuing French, Edward had his army prepare a defensive position on a hillside near Crécy-en-Ponthieu. Late on 26 August the French army, which greatly outnumbered the English, attacked. During a brief archery duel a large force of ...

Navarre
Navarre (; es, Navarra ; eu, Nafarroa ), officially the Chartered Community of Navarre ( es, Comunidad Foral de Navarra, links=no ; eu, Nafarroako Foru Komunitatea, links=no ), is a foral autonomous community and province in northern Spain, bordering the Basque Autonomous Community, La Rioja, and Aragon in Spain and Nouvelle-Aquitaine in France. The capital city is Pamplona ( eu, Iruña). The present-day province makes up the majority of the territory of the medieval Kingdom of Navarre, a long-standing Pyrenean kingdom that occupied lands on both sides of the western Pyrenees, with its northernmost part, Lower Navarre, located in the southwest corner of France. Navarre is in the transition zone between Green Spain and semi-arid interior areas, and thus its landscapes vary widely across the region. Being in a transition zone also produces a highly variable climate, with summers that are a mix of cooler spells and heat waves, and winters that are mild for the latitude. Navarr ...

Moors
The term Moor, derived from the ancient Mauri, is an exonym first used by Christian Europeans to designate the Muslim inhabitants of the Maghreb, the Iberian Peninsula, Sicily and Malta during the Middle Ages. Moors are not a distinct or self-defined people. The 1911 ''Encyclopædia Britannica'' observed that the term had "no real ethnological value." Europeans of the Middle Ages and the early modern period variously applied the name to Arabs and North African Berbers, as well as Muslim Europeans. The term has also been used in Europe in a broader, somewhat derogatory sense to refer to Muslims in general,Menocal, María Rosa (2002).

Roger Bacon
Roger Bacon (; la, Rogerus or ', also '' Rogerus''; ), also known by the scholastic accolade ''Doctor Mirabilis'', was a medieval English philosopher and Franciscan friar who placed considerable emphasis on the study of nature through empiricism. In the early modern era, he was regarded as a wizard and particularly famed for the story of his mechanical or necromantic brazen head. He is sometimes credited (mainly since the 19th century) as one of the earliest European advocates of the modern scientific method, along with his teacher Robert Grosseteste. Bacon applied the empirical method of Ibn al-Haytham (Alhazen) to observations in texts attributed to Aristotle. Bacon discovered the importance of empirical testing when the results he obtained were different from those that would have been predicted by Aristotle. His linguistic work has been heralded for its early exposition of a universal grammar, and 21st-century re-evaluations emphasise that Bacon was essentially a medi ...
