Cannon
A cannon is any large tubular firearm designed to fire a heavy projectile over a long distance. They were first used in China and Europe , and were the archetypical form of artillery.
The first cannon in Europe probably appeared in Moorish and Christian Spain. English cannon were first used during the Hundred Years War, when primitive cannon were used at the Battle of Crécy in 1346. The end of the Middle Ages saw the construction of larger and more powerful cannon, and their spread in warfare throughout the world. East Asia saw the construction of some of the world's largest cannon, such as the Indian Jaivana cannon.
The "giant gun" trend was by then disappearing in Europe, in favor of lighter, more manoeuvrable pieces in larger numbers, and the early use of true field artillery. While the medieval Dardanelles Gun had required 200 men to operate it, 18th century English cannon required only a dozen men, including two gunners, while during the Napoleonic Wars five gunners were used.
Cannon are also sometimes used in certain pieces of music, such as Tchaikovsky's 1812 Overture and AC/DC's For those about to rock, we salute you.

Cannon comes through Old French from Old Italian cannone, ultimately derived from Latin canna—a tube.[1] The Latinised word canon was used for a gun since 1326 in Italy, and 1418 in England. Bombardum, or "bombard", was earliest used for "cannon", but from 1430 it came to refer only to the largest weapons.[2] "Cannon" serves both as the singular and plural of the noun, although the plural "cannons" can also be used. The term can apply to a modern day rifled machine gun with a calibre of 20 mm or more (see autocannon).
Cannon also refers to a large, smooth-bored, muzzle-loading gun used before the advent of breech-loading, rifled guns firing explosive shells. Although a variety of such guns are commonly referred to as "cannon", the term specifically refers to a gun designed to fire a 42 lb shot as opposed to a "Demi-cannon" (32 lb), Culverin (18 lb) or Demi-culverin (9 lb).
When on board a warship a cannon is called a gun, while a cannonball is a roundshot.
History
Early history
Ctesibius of Alexandria invented a primitive form of a cannon, operated by compressed air, before 200 BC. [3]
"Fire lances", gunpowder-propelled arrows, were used in China from at least 1132 AD. The first documented record of artillery with gunpowder propellent used on the battlefield is Huochong used in 1132 to capture a city in Fujian, and by 1161 the Song Dynasty navy on the Yangtze River employed trebuchet catapults to launch gunpowder bombs.[4] Around 1249, the Song Dynasty began to load early gunpowder in the middle of thick bamboo as a projection firearm, firing clay pellets like a shotgun. During the Song Dynasty, portable firearms were introduced in the form of bronze tubes that fired iron balls. Eventually, perishable bamboo was replaced with hollow tubes of cast iron, and so too did the terminology of this new weapon change, from 'fire-spear' ('huo qiang') to 'fire-tube' ('huo tong').[5] Furthermore, by the mid 14th century, the Chinese had discovered how to create explosive cannonballs, by packing their hollow shells with gunpowder.[6] This was described in the medieval Chinese military treatise of the Huolongjing.
Mortars with bronze tubes or bronze first appeared when the Song Dynasty fought the Mongols,[7][8] taking up the use of "true" gunpowder instead of the slower-burning older mixture - which made the early Huochong cannon more reliable and powerful. The Chinese mounted more than 3,000 bronze and iron casted cannons on the Great Wall of China in defence against the Mongols. The weapon was taken up by the Mongol conquerors later, and was also used in Korea.
Medieval Europe and the Middle East
The first mention of the composition of gunpowder in express terms in Europe appeared in 1216, in Roger Bacon's "De nullitate magiæ" at Oxford.[9] Later in 1248, his "Opus Maior" describes a recipe and recognized military use:
"We can, with saltpeter and other substances, compose artificially a fire that can be launched over long distances... By only using a very small quantity of this material much light can be created accompanied by a horrible fracas. It is possible with it to destroy a town or an army ... In order to produce this artificial lightning and thunder it is necessary to take saltpeter, sulfur, and Luru Vopo Vir Can Utriet".
Bacon described firecrackers, "used in certain parts of the world". Bacon's mixture resembles the assumed composition of Chinese slow-burning powder as used in fire arrows and rockets, but will probably not function well as cannon gunpowder - the saltpeter content is too low. Gunpowder was first used in Spain by Moorish cannon at the siege of Seville in 1248, and the siege of Niebla in 1262.[10] By 1260, "coal and sulphur" had been recognised as the best weapon for ship-to-ship combat,[11] while hand guns were probably in use at this time, such as against the Mongols, and Italian scopettieri ("gun bearers") were mentioned in conjunction with crossbowmen in 1281. The Spanish Kings enlisted "the first artillery-masters on the Peninsula" in the mid-14th century.[12]
Cannon saw its first real use on the European battlefield during the Hundred Years War, being only used in small numbers by a few states during the 1340s. "Ribaldis", 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.[13] The Florentine Giovanni Villani recounts their destructiveness on the field, indicating that by the end of the battle, "the whole plain was covered by men struck down by arrows and cannon balls."[14]
Similar cannon appeared also at the Siege of Calais in the same year, although it would not be until the 1380s that the "ribaudekin" clearly became mounted on wheels.[13] Around the same period, the Byzantine Empire began to accumulate its own cannon to face the Ottoman threat, starting with medium-sized cannon 3 feet long and of 10" calibre.[15] The first definite use of artillery in the region was against the Ottoman siege of Constantinople in 1396, forcing the Turks to withdraw.[15] The Turks acquired their own cannon by the siege of 1422, using "falcons", which were short but wide cannon. By 1453, the Turks used 68 Hungarian-made cannon for the 55-day bombardment of Walls of Constantinople, "hurling the pieces everywhere and killing those who happened to be nearby."[15] The largest of which required an operating crew of 200 men,[16] and 70 oxen and 10,000 men just to transport them.[15] Gunpowder had also made the formerly devastating Greek fire obsolete, and with the final fall of what had once been the strongest walls in Europe on May 29, "it was the end of an era in more ways than one".[17]
Post-Medieval Use
The end of the Middle Ages saw the construction of larger and more powerful cannon, and their spread in warfare throughout the world. The Tsar Cannon, founded by Russian founding master Andrey Chokhov in 1586, was the largest howitzer ever made. The cannon, which still survives today, was intended to fire grapeshot and to defend the Kremlin, but was never used. In fact, with such a large cannon, it may have been intended as a showpiece of military might and engineering from the beginning.
Conventional siege artillery, such as siege towers and trebuchets, became vulnerable and obsolete with the development of large cannon and changes in fortification. However, wooden "battery-towers" took on a similar role as siege towers in the gunpowder age, such as that used at siege of Kazan in 1552, which could hold ten large-calibre cannon and 50 lighter cannon.[18]
Most notable in this period, however, is the effect of cannon on conventional fortifications. Niccolò Machiavelli wrote in The Art of War: "There is no wall, whatever its thickness that artillery will not destroy in only a few days". The importance of castles declined, with the loss of importance of majestic towers and merlons. Walls of new fortresses were thicker and angulated, while towers became lower and stouter.
Forts featuring cannon batteries were built during the Renaissance, such as the trace italienne of Italy and the Tudors' Device Forts in England. To guard against artillery and gunfire, increasing use was made of earthen, brick and stone breastworks and redoubts, such as the geometric "Star forts" of the 17th century French Marquis de Vauban. These soon replaced castles in Europe, and eventually castles in the Americas were superseded by bastions and forts.[19]
18th and 19th century
The lower tier of 17th century English ships of the line were usually equipped with demi-cannon — a naval gun which fired a 32-pound solid shot. A full cannon at this time fired a 42-pound shot, but these were discontinued by the 18th century as they were seen as too unwieldy. By the end of the century, principles long adopted in Europe specified the characteristics of cannon of the British ship design and the types and sizes of acceptable defects. The U.S. Navy tested guns by measurement, proof by powder (two or three firings), and using compressed water for leak detection.[20]
The carronade was adopted by the Royal Navy in 1779, and the lower muzzle velocity of the round shot was intended to create many more of the deadly wooden splinters when hitting the structure of an enemy vessel. It was much shorter and a third to a quarter of the weight of an equivalent long gun: for example, a 32 pounder carronade weighed less than a ton, but a 32 pounder long gun weighed over 3 tons. The guns were thus easier to handle and also required less than half the gunpowder of long guns mounted on naval garrison carriages, allowing fewer men to crew them.[21] Carronades were manufactured in the usual naval gun calibres, but they were not counted in a ship of the line's rated number of guns. As a result, the classification of Royal Navy vessels in this period can mislead, since they would often be carrying more pieces of ordnance than were listed.
The Turkish cannons of the siege of Constantinople, after being on permanent display for four centuries, were used to battle a British fleet in 1807. The artillery hit a British ship with two 700 pound cannonballs, killing 60 sailors. In 1867, Sultan Abdul Aziz gifted Queen Victoria the 17 ton "Dardanelles Gun" - one of the cannons used at the siege of Constantinople.[16]
But in contrast to this antiquited weapons, later western guns during the 19th century became massive, destructive, more accurate, and covered a very long range - such as the American 3 inch wrought-iron muzzle-loading howitzer used during the American Civil War with an effective range of over 1.83km. In the 1810s and 1820s, greater emphasis was placed on the accuracy of long-range gunfire, and less on the weight of a broadside. The carronade, although initially very successful and widely adopted, disappeared from the Royal Navy from the 1850s after the development of steel, jacketed cannon by William George Armstrong and Joseph Whitworth. Nevertheless, carronades were used in the American Civil War in the 1860s.
The superior cannon technology of Westerners in later years would bring them tremendous advantages in warfare. For example, in the Opium War in China during the 19th century, the British battleships bombarded the coastal areas and fortifications safe from the reach of the Chinese cannon.
Modern cannon
A modern artillery piece is generally referred to either as a "gun", or by the name of its specific type, such as a Howitzer.
Since World War II, the term cannon is used to refer to a gun of around 20 mm to 125 mm calibre, sometimes with an automatic loading action capable of firing explosive ammunition, an auto-cannon.
The minimum calibre of a cannon, 20 mm, has been a de facto standard since World War II, when heavy machine guns of 12.7 mm (0.5 inches) and 13.2 mm calibre were used side by side with 20 mm and larger guns, the latter using explosive ammunition, e.g., RAF fighters with 20 mm Hispano cannon and Luftwaffe with 20 mm and 30 mm cannon. The Bofors 40 mm gun and Oerlikon 20 mm cannon are two examples largely used during the World War II, and still in use today.
Most nations use these modern (auto-) cannon on their lighter vehicles. Typical of the type is the 25 mm 'Bushmaster' cannon mounted on the LAV and Bradley armoured vehicles.
Today, United States 152 mm artillery fires Shillelagh missiles, which are guided to their targets by infra-red beams, while the Super High Altitude Research Project artillery can fire shells 75.75 mi. above the earth's surface.[16]
A cannon generally refers to a high velocity, low trajectory, direct fire weapon such as the main gun on most modern main battle tanks.
A howitzer generally refers to a weapon using a lower velocity than a cannon, which fires on a higher trajectory, and provides indirect fire.
These are both differentiated from a mortar, which fires a low velocity (by comparison) round at very high trajectory at much more limited range.
Operation
Cannon operation during the 18th century is described by the 1771 Encyclopædia Britannica. Each cannon would be manned by two gunners, six soldiers, and four officers of artillery. The right gunner was to prime the piece and load it with powder, while the left gunner would fetch the powder from the magazine and keep ready to fire the cannon at the officer's command. Three soldiers stood on each side of the cannon, to ram and sponge the cannon, and hold the lantern and ladle. The second soldier on the left was charged with providing 50 bullets.[22]
Prior to loading, the cannon would be well cleaned with a sponge to remove all sparks, filth, and dirt. The powder was added, followed by a wad of paper or hay, and the ball was thrown in. After ramming the cannon would be aimed with the elevation set using a quadrant and a plummet. At 45 degrees, the ball had the utmost range – about ten times the gun's level range. Any angle above the horizontal line was called random-shot. The officer of artillery had to ensure the cannon was diligently served. Water was available to dip the sponges in and cool the pieces every ten or twelve rounds.[22]
It was said that a 24-pounder could fire 90 to 100 shots a day in summer, or 60 to 75 in winter. A 16 or 12 pounder would fire a little more, because they were easier served. The Britannica mentions "some occasions where 200 shots have been fired from these pieces in the space of nine hours, and 138 in the space of five."[22]
During the Napoleonic Wars, a British gun team consisted of 5 numbered gunners. The gun's "No. 1" was the gun commander, and a sergeant, who aimed the gun. The No. 2 was the "spongeman" who cleaned the bore with the sponge dampened with water between shots; the intention being to quench any remaining embers before a fresh charge was introduced. The No. 3, the loader, inserted the bag of powder and then the projectile. The No. 2 then used a rammer, or the sponge reversed, to drive it in. At the same time, the No. 4 ("ventsman") pressed his thumb on the vent hole to prevent a draught that might fan a flame. The charge loaded, the No. 4 pricked the bagged charge through the vent hole and filled the vent with powder. At the No. 1's command the No. 5 would fire the piece with his slowmatch.[23]
In music
The cannon can be used as a kind of percussion instrument in certain pieces of music. The best known example is the 1812 Overture by Tchaikovsky, which should properly be played using an artillery section together with the orchestra. It is supposed to simulate the Battle of Borodino. The version using cannon fire was first laid down on a recording by the Minneapolis Symphony Orchestra in the 1950s. Subsequent similar recordings have been made by other groups, exploiting the advances in audio technology. Cannon fire is used annually on the Fourth of July by the Boston Pops during their annual concert on the shores of the Charles River and by the National Symphony Orchestra during their annual concert on the steps of the US Capitol Building.
The hard rock band AC/DC also use cannon in their song For those about to rock, we salute you. The album of the same name also features a cannon on its cover.
Due to their impracticalities, cannon are used for only grand, theatrical pieces, often with a military theme. In the case of the 1812, the cannon may be replaced with bass drums or timpani. Less frequently strongly accented snare drum diminuendos can be heard.
