Howitzer
–
In the taxonomies of artillery pieces used by European armies in the 17th to 20th centuries, the howitzer stood between the gun and the mortar. Howitzers, like other artillery equipment, are organized in groups called batteries. The English word howitzer comes from the Czech word houfnice, from houf, crowd, haufen, sometimes in the compound Gewalthaufen, also designated a pike square formation in German. This is particularly true in the forces of the United States. Because of this practice, the howitzer is used in some armies as a generic term for any kind of artillery piece that is designed to attack targets using indirect fire. Thus, artillery pieces that bear resemblance to howitzers of earlier eras are now described as howitzers. Most other armies in the reserve the word howitzer for guns with barrel lengths 15 to 25 times their caliber. The British had a method of nomenclature. In the 18th century, they adopted projectile weight for guns replacing the old naming system of culverin, saker, mortars had been categorized by calibre in inches in the 17th century and this was inherited by howitzers. The modern howitzers were invented in Sweden towards the end of the 17th century, originally intended for use in siege warfare, they were particularly useful for delivering cast-iron shells filled with gunpowder or incendiary materials into the interior of fortifications. In the middle of the 18th century, a number of European armies began to introduce howitzers that were enough to accompany armies in the field. Though usually fired at the high angles of fire used by contemporary siege howitzers. Rather, as the guns of the day were usually restricted to inert projectiles. Many, for the sake of simplicity and rapidity of fire, the Abus gun was an early form of howitzer in the Ottoman Empire. In 1758 the Russian Empire introduced a type of howitzer, with a conical chamber, called a licorne. The most famous of these gun-howitzers was the Napoleon 12-pounder, a weapon of French design that saw service in the American Civil War. The longest-serving artillery piece of the 19th century was the mountain howitzer, in 1859, the armies of Europe began to rearm field batteries with rifled field guns. These new field pieces used cylindrical projectiles that, while smaller in caliber than the spherical shells of smoothbore field howitzers, moreover, their greater range let them create many of the same effects that previously required the sharply curved trajectories of smoothbore field howitzers

Second Boer War
–
The Second Boer War, usually known as the Boer War and also at the time as the South African War, started on 11 October 1899 and ended on 31 May 1902. Great Britain defeated two Boer states in South Africa, the South African Republic and the Orange Free State, Britain was aided by its Cape Colony, Colony of Natal and some native African allies. The British war effort was supported by volunteers from the British Empire, including Southern Africa, the Australian colonies, Canada, India. All other nations were neutral, but public opinion in them was largely hostile to Britain, inside Britain and its Empire there also was significant opposition to the Second Boer War. The British were overconfident and under-prepared, the Boers were very well armed and struck first, besieging Ladysmith, Kimberley, and Mafeking in early 1900, and winning important battles at Colenso, Magersfontein and Stormberg. Staggered, the British brought in numbers of soldiers and fought back. General Redvers Buller was replaced by Lord Roberts and Lord Kitchener and they relieved the three besieged cities, and invaded the two Boer republics in late 1900. The onward marches of the British Army were so overwhelming that the Boers did not fight staged battles in defense of their homeland, the British quickly seized control of all of the Orange Free State and Transvaal, as the civilian leadership went into hiding or exile. In conventional terms, the war was over, Britain officially annexed the two countries in 1900, and called a khaki election to give the government another six years of power in London. However, the Boers refused to surrender and they reverted to guerrilla warfare under new generals Louis Botha, Jan Smuts, Christiaan de Wet and Koos de la Rey. Two more years of attacks and quick escapes followed. As guerrillas without uniforms, the Boer fighters easily blended into the farmlands, which provided hiding places, supplies, the British solution was to set up complex nets of block houses, strong points, and barbed wire fences, partitioning off the entire conquered territory. The civilian farmers were relocated into concentration camps, where very large proportions died of disease, especially the children, then the British mounted infantry units systematically tracked down the highly mobile Boer guerrilla units. The battles at this stage were small operations with few combat casualties The war ended in surrender, the British successfully won over the Boer leaders, who now gave full support to the new political system. Both former republics were incorporated into the Union of South Africa in 1910, the conflict is commonly referred to as simply the Boer War, since the First Boer War is much less well known. Boer was the term for Afrikaans-speaking white South Africans descended from the Dutch East India Companys original settlers at the Cape of Good Hope. It is officially called the South African War and it is known as the Anglo-Boer War among some South Africans. In Afrikaans it may be called the Anglo-Boereoorlog, Tweede Boereoorlog, in South Africa it is officially called the South African War

World War I
–
World War I, also known as the First World War, the Great War, or the War to End All Wars, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history and it was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. The war drew in all the worlds great powers, assembled in two opposing alliances, the Allies versus the Central Powers of Germany and Austria-Hungary. These alliances were reorganised and expanded as more nations entered the war, Italy, Japan, the trigger for the war was the assassination of Archduke Franz Ferdinand of Austria, heir to the throne of Austria-Hungary, by Yugoslav nationalist Gavrilo Princip in Sarajevo on 28 June 1914. This set off a crisis when Austria-Hungary delivered an ultimatum to the Kingdom of Serbia. Within weeks, the powers were at war and the conflict soon spread around the world. On 25 July Russia began mobilisation and on 28 July, the Austro-Hungarians declared war on Serbia, Germany presented an ultimatum to Russia to demobilise, and when this was refused, declared war on Russia on 1 August. Germany then invaded neutral Belgium and Luxembourg before moving towards France, after the German march on Paris was halted, what became known as the Western Front settled into a battle of attrition, with a trench line that changed little until 1917. On the Eastern Front, the Russian army was successful against the Austro-Hungarians, in November 1914, the Ottoman Empire joined the Central Powers, opening fronts in the Caucasus, Mesopotamia and the Sinai. In 1915, Italy joined the Allies and Bulgaria joined the Central Powers, Romania joined the Allies in 1916, after a stunning German offensive along the Western Front in the spring of 1918, the Allies rallied and drove back the Germans in a series of successful offensives. By the end of the war or soon after, the German Empire, Russian Empire, Austro-Hungarian Empire, national borders were redrawn, with several independent nations restored or created, and Germanys colonies were parceled out among the victors. During the Paris Peace Conference of 1919, the Big Four imposed their terms in a series of treaties, the League of Nations was formed with the aim of preventing any repetition of such a conflict. This effort failed, and economic depression, renewed nationalism, weakened successor states, and feelings of humiliation eventually contributed to World War II. From the time of its start until the approach of World War II, at the time, it was also sometimes called the war to end war or the war to end all wars due to its then-unparalleled scale and devastation. In Canada, Macleans magazine in October 1914 wrote, Some wars name themselves, during the interwar period, the war was most often called the World War and the Great War in English-speaking countries. Will become the first world war in the sense of the word. These began in 1815, with the Holy Alliance between Prussia, Russia, and Austria, when Germany was united in 1871, Prussia became part of the new German nation. Soon after, in October 1873, German Chancellor Otto von Bismarck negotiated the League of the Three Emperors between the monarchs of Austria-Hungary, Russia and Germany

Shell (projectile)
–
A shell is a payload-carrying projectile that, as opposed to shot, contains an explosive or other filling, though modern usage sometimes includes large solid projectiles properly termed shot. Solid shot may contain a pyrotechnic compound if a tracer or spotting charge is used, originally, it was called a bombshell, but shell has come to be unambiguous in a military context. Words cognate with grenade are still used for an artillery or mortar projectile in some European languages, shells are usually large-calibre projectiles fired by artillery, combat vehicles, and warships. Shells usually have the shape of a cylinder topped by a nose for good aerodynamic performance, possibly with a tapering base. Solid cannonballs did not need a fuse, but hollow munitions filled with something such as gunpowder to fragment the ball, needed a fuse, percussion fuses with a spherical projectile presented a challenge because there was no way of ensuring that the impact mechanism hit the target. Therefore, shells needed a fuse that was ignited before or during firing. The earliest record of shells being used in combat was by the Republic of Venice at Jadra in 1376, shells with fuses were used at the 1421 siege of St Boniface in Corsica. These were two hollowed hemispheres of stone or bronze held together by an iron hoop, as described in their book, these hollow, gunpowder-packed shells were made of cast iron. At least since the 16th Century grenades made of ceramics or glass were in use in Central Europe, a hoard of several hundred ceramic greandes were discovered during building works in front of a bastion of the Bavarian City of Ingolstadt, Germany dated to the 17th Century. Lots of the grenades obtained their orignal blackpowder loads and igniters, most probably the grenades were intentionally dumped the moat of the bastion before the year 1723. Early powder burning fuses had to be loaded fuse down to be ignited by firing or a portfire put down the barrel to light the fuse, other shells were wrapped in bitumen cloth, which would ignite during the firing and in turn ignite a powder fuse. Nevertheless, shells came into use in the 16th Century. By the 18th Century, it was known that the fuse towards the muzzle could be lit by the flash through the windage between the shell and the barrel, the use of exploding shells from field artillery became relatively commonplace from early in the 19th century. Until the mid 19th century, shells remained as simple exploding spheres that used gunpowder and they were usually made of cast iron, but bronze, lead, brass and even glass shell casings were experimented with. The word bomb encompassed them at the time, as heard in the lyrics of The Star-Spangled Banner, typically, the thickness of the metal body was about a sixth of their diameter and they were about two thirds the weight of solid shot of the same calibre. To ensure that shells were loaded with their fuses towards the muzzle, in 1819, a committee of British artillery officers recognised that they were essential stores and in 1830 Britain standardised sabot thickness as a half inch. The sabot was also intended to reduce jamming during loading, despite the use of exploding shell, the use of smoothbore cannons, firing spherical projectiles of shot, remained the dominant artillery method until the 1850s. By the late 18th century, artillery could use canister shot to defend itself from infantry or cavalry attack and this involved loading a tin or canvas container filled with small iron or lead balls instead of the usual cannonball

Glossary of British ordnance terms
–
This article explains terms used for the British Armed Forces ordnance and also ammunition. The terms may have different meanings in the military of other countries. Between decks, applies to a gun mounting in which part of the rotating mass is below the deck. This allows for a profile of turret, meaning that turrets need not be superfiring The term BL, in its general sense, stood for breech loading. The shell was loaded via the breech followed by the propellant charge, sealing the chamber to prevent escape of the propellant gases. The term BL was first used to refer to the Armstrong breechloaders, following the discontinuation of Armstrong breechloaders and the period of British rifled muzzle-loaders, British breechloaders were re-introduced in 1880. Early British Elswick breechloaders in the 1880s used a steel cup obturation method and this was quickly superseded in guns designed by the Royal Gun Factory by the French de Bange method, the basic principle of which is still in use today. In British service this became a Crossley pad with an interrupted thread screw block e. g. a Welin screw, the shell was loaded via the breech, followed by the propellant charge in a cloth bag. A single-use vent sealing tube, a type of primer not dissimilar in appearance to a rifle round, was inserted into the breech for firing the gun. For instance, Britain before World War I had both QF and BL6 inch guns and this presented difficulties for BL guns at high angles. A special cartridge was developed for BL9.2 inch guns on H. A. mountings, using multiple small fabric bags also allows the gunners to use a reduced charge if need be. The term BLC stood for BL converted and referred to a breech and breech mechanism modified from an early long-screw three- or four-motion to modern short-screw single-motion, an example is the conversion of the BL15 pounder to BLC15 pounder. Calibre radius head, the radius of a circle with the curve of the nose on its circumference. The longer and more pointed the nose, the higher the C. R. H. Typical C. R. H. for British shells leading up to World War I was two, e. g. the curve of the nose of a two C. R. H. Six-inch shell was equivalent to the curve of a circle with a radius of 12 inches, shells of four C. R. H. were soon developed in World War I, identified by an A following the shell mark number, B for six and so on. For modern streamlined shells post-World War I, two numbers were necessary to more correctly denote a shells C. R. H, for instance, the World War I6 inch 26 cwt howitzer shell was two C. R. H. The World War II Mk 2D shell was correctly described as 5/10 C. R. H, in this use it is synonymous with round

Shrapnel shell
–
They relied almost entirely on the shells velocity for their lethality. The munition has been obsolete since the end of World War I for anti-personnel use, the functioning and principles behind Shrapnel shells are fundamentally different from high-explosive shell fragmentation. In 1784, Lieutenant Shrapnel of the Royal Artillery began developing an anti-personnel weapon, when fired, the container burst open during passage through the bore or at the muzzle, giving the effect of an oversized shotgun shell. At ranges of up to 300 m canister shot was still highly lethal, though at this range the shots’ density was much lower and his shell was a hollow cast-iron sphere filled with a mixture of balls and powder, with a crude time fuze. If the fuze was set correctly then the shell would break open, either in front or above the intended target, the shrapnel balls would carry on with the remaining velocity of the shell. The explosive charge in the shell was to be just enough to break the casing rather than scatter the shot in all directions, as such his invention increased the effective range of canister shot from 300 to about 1100 m. He called his device spherical case shot, but in time it came to be called after him, Various solutions were tried, with limited if any success. However, in 1852 Colonel Boxer proposed using a diaphragm to separate the bullets from the bursting charge, as a buffer to prevent lead shot deforming, a resin was used as a packing material between the shot. A useful side effect of using the resin was that the combustion also gave a visual reference upon the shell bursting and it took until 1803 for the British artillery to adopt the shrapnel shell, albeit with great enthusiasm when it did. Henry Shrapnel was promoted to major in the same year, the first recorded use of shrapnel by the British was in 1804 against the Dutch at Fort Nieuw-Amsterdam in Surinam. The Duke of Wellingtons armies used it from 1808 in the Peninsular War and at the Battle of Waterloo, the design was improved by Captain E. M. Boxer of the Royal Arsenal around 1852 and crossed over when cylindrical shells for rifled guns were introduced. The powder charge both shattered the cast iron wall and liberated the bullets. The broken shell wall continued mainly forward but had little destructive effect, in the 1870s William Armstrong provided a design with the bursting charge in the head and the shell wall made of steel and hence much thinner than previous cast-iron shrapnel shell walls. Britain adopted this solution for several smaller calibres but by World War I few if any such shells remained, the final shrapnel shell design, adopted in the 1880s, bore little similarity to Henry Shrapnels original design other than its spherical bullets and time fuze. It used a much thinner forged steel shell case with a fuze in the nose. The use of steel allowed the wall to be made much thinner. It also withstood the force of the charge without shattering, so that the bullets were fired forward out of the shell case with increased velocity. This is the design came to be adopted by all countries and was in standard use when World War I began in 1914

Recoil
–
Recoil is the backward movement of a gun when it is discharged. To apply this counter-recoiling force, modern mounted guns may employ recoil buffering comprising springs and hydraulic recoil mechanisms, early cannons used systems of ropes along with rolling or sliding friction to provide forces to slow the recoiling cannon to a stop. Recoil buffering allows the maximum counter-recoil force to be lowered so that strength limitations of the gun mount are not exceeded, however, the same pressures acting on the base of the projectile are acting on the rear face of the gun chamber, accelerating the gun rearward during firing. This results in the required counter-recoiling force being proportionally lower, modern cannons also employ muzzle brakes very effectively to redirect some of the propellant gasses rearward after projectile exit. This provides a force to the barrel, allowing the buffering system. The same physics affecting recoil in mounted guns and cannons applies to hand-held guns, hands, arms and shoulders have considerable strength and elasticity for this purpose, up to certain practical limits. For this reason, establishing recoil safety standards for small arms remains challenging, a change in momentum of a mass requires a force, according to Newtons first law, known as the law of inertia, inertia simply being another term for mass. That force, applied to a mass, creates an acceleration, according to Newtons second law, the law of momentum -- changing the velocity of the mass changes its momentum. It is important to understand at this point that velocity is not simply speed, velocity is the speed of a mass in a particular direction. In a very technical sense, speed is a scalar, a magnitude, in summation, the total momentum of the system equals zero, surprisingly just as it did before the trigger was pulled. There are two conservation laws at work when a gun is fired, conservation of momentum and conservation of energy, recoil is explained by the law of conservation of momentum, and so it is easier to discuss it separately from energy. The nature of the process is determined by the force of the expanding gases in the barrel upon the gun. It is also determined by the force applied to the gun. The recoil force only acts during the time that the ejecta are still in the barrel of the gun, except for the case of zero-recoil, the counter-recoil force is smaller than the recoil force but lasts for a longer time. Since the recoil force and the force are not matched. In the zero-recoil case, the two forces are matched and the gun will not move when fired. In most cases, a gun is very close to a free-recoil condition, an example of near zero-recoil would be a gun securely clamped to a massive or well-anchored table, or supported from behind by a massive wall. For example, placing the butt of a large caliber gun directly against a wall, the recoil of a firearm, whether large or small, is a result of the law of conservation of momentum

Gun carriage
–
A gun carriage is a frame and mount that supports the gun barrel of an artillery piece, allowing it to be manoeuvred and fired. The earliest guns were laid directly onto the ground, with earth being piled up under the end of the barrel to increase the elevation. As the size of guns increased, they began to be attached to wooden frames or beds that were held down by stakes. These began to be replaced by wheeled carriages in the early 16th century, from the 16th to the mid-19th century, the main form of artillery remained the smoothbore cannon. By this time, the trunnion had been developed, with the result that the barrel could be held in two recesses in the carriage and secured with an iron band. This simplified elevation, which was achieved by raising or lowering the breech of the gun by means of a wedge called a quoin or later by a steel screw. During this time, the design of gun carriages evolved only slowly, the trunnions of the gun barrel sat on the top of the cheeks, the rearward part of each cheek was stepped so that the breech could be lifted by iron levers called handspikes. Traversing the gun was achieved by levering the rear of the carriage sideways with handspikes and these were designed to allow guns to be deployed on the battlefield and were provided with a pair of large wheels similar to those used on carts or wagons. The cheeks of field carriages were much narrower than those on the naval carriage, when the gun needed to be moved any distance, the trail could be lifted onto a second separate axle called a limber, which could then be towed by a team of horses or oxen. Limbers had been invented in France in about 1550, in recent times, most heavy guns in military service, that were not themselves mounted into a vehicles, have been mounted either with a field carriage or a split trail carriage. The field carriage is simpler - having two legs extend backwards, joining at a tail, being a hardpoint to hook on to a prime mover or set of horses, the split trail carriage, however, is more complicated, but offers distinct advantages. It consists of two legs, able to be spread independently to the sides, or brought together to allow towing or movement, in both cases, the tail of the carriage often serves to balance the gun, and protect it from rolling to any large extent. The split trail, however, allows the gun not only to be fired near the horizontal, as the field carriage does and this is less important for heavier artillery, as the guns already involve a long time to prepare a firing position. While this still limits the ability to track, it allows the guns to fire in any direction with minimal preparation. Furthermore, it part of each of the benefits of the field carriage, being weight, space. The practice has its origins in war and appears in the century in the Queens regulations of the British Army. In the United Kingdom, the visual distinction usually referred to is that in a state funeral and this distinguishing feature is not invariable, however, as shown by the use of naval ratings rather than horses at the ceremonial funeral for Lord Mountbatten in 1979

BL 6-inch 26 cwt howitzer
–
The Ordnance BL6 inch 26cwt howitzer was a British howitzer used during World War I and World War II. The qualifier 26cwt refers to the weight of the barrel and breech together which weighed 26 long hundredweight and it was developed to replace the obsolescent 6 inch 25 cwt and 6 inch 30 cwt howitzers which were outclassed by German artillery such as the 15 cm schwere Feldhaubitze 13. Design began in January 1915, the first proof-firing occurred on 30 July 1915 and its combination of firepower, range and mobility made it one of the British Empires most important weapons in World War I. It was originally towed by horses but from 1916 onwards was commonly towed by the FWD4 wheel drive 3 ton lorry as heavy field artillery, the wooden spoked wheels could be fitted with girdles for work in mud or sand to prevent them sinking. Towards the end of the war solid rubber tyres were fitted over the iron tyres on the wheel rims and it fired 22.4 million rounds on the Western Front. During the interwar period the carriage had its wooden spoked wheels replaced with steel wheels. During World War II, its use was restricted after 1942 when the replacement BL5.5 inch Medium Gun came into use and it was however reintroduced in Burma due to a number of premature detonations in 5. 5-inch guns. It was declared obsolete with the end of the war in 1945, captured examples received the designation FH-412 in German use.
