WFire arrows were one of the earliest forms of weaponized gunpowder, being used from the 9th century onward. Not to be confused with earlier incendiary arrow projectiles, the fire arrow was a gunpowder weapon which receives its name from the translated Chinese term huǒjiàn (火箭), which literally means fire arrow. In China a 'fire arrow' referred to a gunpowder projectile consisting of a bag of incendiary gunpowder attached to the shaft of an arrow. Fire arrows are the predecessors of fire lances, the first firearm.
WGunpowder weapons in the Song dynasty included the "multiple bullets magazine erupters", consisting of a tube of bronze or cast iron that was filled with about 100 lead balls, and the "flying-cloud thunderclap eruptor", an early cast-iron proto-cannon. The use of proto-cannon, and other gunpowder weapons, enabled the Song dynasty to ward off its militant enemies—the Liao, Western Xia, and Jin—until its final collapse under the onslaught of the Mongol forces of Kublai Khan in the late 13th century.
WHongyipao was the Chinese name for European-style muzzle-loading culverins introduced to China and Korea from the Portuguese colony of Macau and by the Hendrick Hamel expedition to Joseon in the early 17th century.
WHu dun pao (虎蹲砲) is the name of two different missile weapons in Chinese history. In the Song dynasty (960–1279), it was a trebuchet and its name is translated into English as Crouching Tiger Trebuchet; in the Ming dynasty (1368–1644), the name was given to a type of bombard and it is known in English as Crouching Tiger Cannon.
WThe Huolongjing, also known as Huoqitu, is a 14th-century military treatise compiled and edited by Jiao Yu and Liu Bowen of the early Ming dynasty (1368–1683). The Huolongjing is primarily based on the text known as Huolong Shenqi Tufa, which is no longer extant.
WThe mangonel, also called the traction trebuchet, was a type of trebuchet or siege engine used in Ancient China starting from the Warring States period, and later across Eurasia by the 6th century AD. Unlike the earlier torsion engines and later counterweight trebuchet, the mangonel operated on manpower pulling cords attached to a lever and sling to launch projectiles. Although the mangonel required more men to function, it was also less complex and faster to reload than the torsion-powered ballista and onager which it replaced in early Medieval Europe. It was replaced as the primary siege weapon in the 12th and 13th centuries by the counterweight trebuchet.
WA trebuchet is a type of catapult that uses a long arm to throw a projectile. It was a common powerful siege engine until the advent of gunpowder.
WThe Wuwei Bronze Cannon or Xi Xia Bronze cannon was discovered in 1980 and is probably the oldest and largest cannon dated to the 13th century. This 100 centimeter long, 108 kilogram bronze cannon was discovered in a cellar in Wuwei, Gansu Province. It bears no inscription, but has been dated by historians to the late Western Xia period between 1214 and 1227 through contextual evidence. The gun contained an iron ball about nine centimeters in diameter, which is smaller than the muzzle diameter at twelve centimeters, and 0.1 kilograms of gunpowder in it when discovered, meaning that the projectile might have been another co-viative. Ben Sinvany and Dang Shoushan believe that the ball used to be much larger prior to its highly corroded state at the time of discovery. While large in size, the weapon is noticeably more primitive than later Yuan dynasty guns such as the Xanadu Gun and Heilongjiang hand cannon, and is unevenly cast. A similar weapon was discovered not far from the discovery site in 1997, but is much smaller in size at only 1.5 kg.
WThe oldest extant gun bearing a date of production is the Xanadu Gun, so called because it was discovered in the ruins of Xanadu (Shangdu), the summer palace of the Yuan dynasty in Inner Mongolia, China. The Xanadu Gun is 34.7 cm in length and weighs 6.21 kg, its muzzle is flared outwards, slightly bowl-shape, and called by Chinese as 碗口铳. Its dating is based on archaeological context and a straightforward inscription containing an era name and year that correspond with the Gregorian Calendar at 1298. Not only does the inscription contain the era name and date, it also includes a serial number and manufacturing information which suggests that gun production had already become systematized, or at least become a somewhat standardized affair by the time of its fabrication. The design of the gun includes axial holes in its rear which some speculate could have been used in a mounting mechanism. Like most early guns with the possible exception of the Western Xia gun, it is small, weighing just over six kilograms and thirty-five centimeters in length. Although the Xanadu Gun is the most precisely dated gun from the 13th century, other extant samples with approximate dating may be older.
