Cannon
A cannon is a large-caliber gun classified as a type of artillery, which usually launches a projectile using explosive chemical propellant. Gunpowder 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.
The earliest known depiction of cannons may have appeared in Song dynasty China as early as the 12th century; however, solid archaeological and documentary evidence of cannons do not appear until the 13th century. In 1288, Yuan dynasty troops are recorded to have used hand cannons in combat, and the earliest extant cannon bearing a date of production comes from the same period. By the end of the 14th century, cannons were widespread throughout Eurasia.
Cannons were used primarily as anti-infantry weapons until around 1374, when large cannons were recorded to have breached walls for the first time in Europe. Cannons featured prominently as siege weapons. In 1464 a cannon known as the Great Turkish Bombard was created in the Ottoman Empire. Cannons as field artillery became more important after 1453 when cannons broke down the walls of the Roman Empire's capital, with the introduction of limber, which greatly improved cannon maneuverability and mobility. European cannons reached their longer, lighter, more accurate, and more efficient "classic form" around 1480. This classic European cannon design stayed relatively consistent in form with minor changes until the 1750s.
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.
Etymology and terminology
The word cannon is derived from the Old Italian word cannone, meaning "large tube", which came from the Latin canna, in turn originating from the Greek κάννα, "reed", and then generalised to mean any hollow tube-like object. The word has been used to refer to a gun since 1326 in Italy and 1418 in England. The plural forms cannons and cannon are both correct.Early history
East Asia
The cannon may have appeared as early as the 12th century in China, and was probably a parallel development or evolution of the fire-lance, a short ranged anti-personnel weapon combining a gunpowder-filled tube and a polearm. Projectiles such as iron scraps or porcelain shards, mixed together with the gunpowder, were placed in fire lance barrels at some point, and eventually, the paper and bamboo materials of fire lance barrels were replaced by metal.The earliest known depiction of a cannon is a sculpture from the Dazu Rock Carvings in Sichuan dated to 1128, however, the earliest archaeological samples and textual accounts do not appear until the 13th century. The primary extant specimens of cannon from the 13th century are the Wuwei Bronze Cannon dated to 1227, the Heilongjiang hand cannon dated to 1288, and the Xanadu Gun dated to 1298. However, only the Xanadu gun contains an inscription bearing a date of production, so it is considered the earliest confirmed extant cannon. The Xanadu Gun is in length and weighs. The other cannons are dated using contextual evidence. The Heilongjiang hand cannon is also often considered by some to be the oldest firearm since it was unearthed near the area where the History of Yuan reports a battle took place involving hand cannons. According to the History of Yuan, in 1288, a Jurchen commander by the name of Li Ting led troops armed with hand cannons into battle against the rebel prince Nayan.
Chen Bingying argues there were no guns before 1259, while Dang Shoushan believes the Wuwei gun and other Western Xia era samples point to the appearance of guns by 1220, and Stephen Haw goes even further by stating that guns were developed as early as 1200. Sinologist Joseph Needham and renaissance siege expert Thomas Arnold provide a more conservative estimate of around 1280 for the appearance of the "true" cannon. Whether or not any of these are correct, it seems likely that the gun was born sometime during the 13th century.
References to cannons proliferated throughout China in the following centuries. Cannon featured in literary pieces. In 1341 Xian Zhang wrote a poem called The Iron Cannon Affair describing a cannonball fired from an eruptor which could "pierce the heart or belly when striking a man or horse, and even transfix several persons at once." By the 1350s the cannon was used extensively in Chinese warfare. In 1358 the Ming army failed to take a city due to its garrisons' usage of cannon, however, they themselves would use cannon, in the thousands, later on during the siege of Suzhou in 1366.
The Mongol invasion of Java in 1293 brought gunpowder technology to the Nusantara archipelago in the form of cannon. During the Ming dynasty cannons were used in riverine warfare at the Battle of Lake Poyang. One shipwreck in Shandong had a cannon dated to 1377 and an anchor dated to 1372. From the 13th to 15th centuries cannon-armed Chinese ships also travelled throughout Southeast Asia. Cannon appeared in Đại Việt by 1390 at the latest.
The first of the western cannon to be introduced were breech-loaders in the early 16th century, which the Chinese began producing themselves by 1523 and improved on by including composite metal construction in their making.
Japan did not acquire cannon until 1510 when a monk brought one back from China, and did not produce any in appreciable numbers. During the 1593 siege of Pyongyang, 40,000 Ming troops deployed a variety of cannons against Japanese troops. Despite their defensive advantage and the use of arquebus by Japanese soldiers, the Japanese were at a severe disadvantage due to their lack of cannon. Throughout the Japanese invasions of Korea, the Ming–Joseon coalition used artillery widely in land and naval battles, including on the turtle ships of Yi Sun-sin.
According to Ivan Petlin, the first Russian envoy to Beijing, in September 1619, the city was armed with large cannon with cannonballs weighing more than.
Western Europe
Outside of China, the earliest texts to mention gunpowder are Roger Bacon's Opus Majus and Opus Tertium in what has been interpreted as references to firecrackers. In the early 20th century, a British artillery officer proposed that another work tentatively attributed to Bacon, Epistola de Secretis Operibus Artis et Naturae, et de Nullitate Magiae, dated to 1247, contained an encrypted formula for gunpowder hidden in the text. These claims have been disputed by science historians. In any case, the formula itself is not useful for firearms or even firecrackers, burning slowly and producing mostly smoke.There is a record of a gun in Europe dating to 1322 that was discovered in the nineteenth century, but the artifact has since been lost. The earliest known European depiction of a gun appeared in 1326 in a manuscript by Walter de Milemete, although not necessarily drawn by him, known as De Nobilitatibus, sapientii et prudentiis regum, which displays a gun with a large arrow emerging from it and its user lowering a long stick to ignite the gun through the touch hole. In the same year, another similar illustration showed a darker gun being set off by a group of knights, in another work of de Milemete's, De secretis secretorum Aristotelis. On 11 February of that same year, the Signoria of Florence appointed two officers to obtain canones de mettallo and ammunition for the town's defense. In the following year a document from the Turin area recorded a certain amount was paid "for the making of a certain instrument or device made by Friar Marcello for the projection of pellets of lead". A reference from 1331 describes an attack mounted by two Germanic knights on Cividale del Friuli, using man-portable gunpowder weapons of some sort. The 1320s seem to have been the takeoff point for guns in Europe according to most modern military historians. Scholars suggest that the lack of gunpowder weapons in a well-traveled Venetian's catalogue for a new crusade in 1321 implies that guns were unknown in Europe up until this point, further solidifying the 1320 mark, however more evidence in this area may be forthcoming in the future.
The oldest extant cannon in Europe is a small bronze example unearthed in Loshult, Scania in southern Sweden. It dates from the early-mid 14th century, and is currently in the Swedish History Museum in Stockholm.
Early cannons in Europe often shot arrows and were known by an assortment of names such as pot-de-fer, tonnoire, ribaldis, and büszenpyle. The ribaldis, which shot large arrows and simplistic grapeshot, were first mentioned in the English Privy Wardrobe accounts during preparations for the Battle of Crécy, between 1345 and 1346. The Florentine Giovanni Villani recounts their destructiveness, indicating that by the end of the battle, "the whole plain was covered by men struck down by arrows and cannon balls". Similar cannon were also used at the siege of Calais, although it was not until the 1380s that the ribaudekin clearly became mounted on wheels.
The Battle of Crecy which pitted the English against the French in 1346 featured the early use of cannon which helped the longbowmen repulse a large force of Genoese crossbowmen deployed by the French. The English originally intended to use the cannon against cavalry sent to attack their archers, thinking that the loud noises produced by their cannon would panic the advancing horses along with killing the knights atop them.
Early cannons could also be used for more than simply killing men and scaring horses. English cannon were used defensively in 1346 during the siege of Breteuil to launch fire onto an advancing siege tower. In this way, cannons could be used to burn down siege equipment before it reached the fortifications. The use of cannons to shoot fire could also be used offensively as another battle involved the setting of a castle ablaze with similar methods. The particular incendiary used in these projectiles was most likely a gunpowder mixture. This is one area where early Chinese and European cannons share a similarity as both were possibly used to shoot fire.
Another aspect of early European cannons is that they were rather small, dwarfed by the bombards, which would come later. In fact, it is possible that the cannons used at Crécy were capable of being moved rather quickly as there is an anonymous chronicle that notes the guns being used to attack the French camp, indicating that they would have been mobile enough to press the attack. These smaller cannons would eventually give way to larger, wall-breaching guns by the end of the 1300s.
