Siege gun
–
A siege engine is a device that is designed to break or circumvent city walls and other fortifications in siege warfare. Some have been operated close to the fortifications, while others have used to attack from a distance. From antiquity, siege engines were constructed largely of wood and tended to use mechanical advantage to fling stones, with the development of gunpowder and improved metallurgical techniques, siege engines became artillery. Collectively, siege engines or artillery together with the necessary troops, the earliest engine was the battering ram, developed by the Assyrians, followed by the catapult in ancient Greece. The first Mediterranean people to use advanced siege machinery were the Carthaginians and these engines influenced the ruler of Syracuse, Dionysius I, who developed a catapult in 399 BC. The first two rulers to use of siege engines to a large extent were Philip II of Macedonia. The most utilized engines were simple battering rams, or tortoises, for sea sieges or battles, seesaw-like machines were used. These were giant ladders, hinged and mounted on a base mechanism and they were normally mounted on two or more ships tied together and some sambykē included shields at the top to protect the climbers from arrows. Other hinged engines were used to catch enemy equipment or even opposing soldiers with opposable appendices which are probably ancestors to the Roman corvus, other weapons dropped heavy weights on opposing soldiers. The Romans preferred to assault enemy walls by building earthen ramps or simply scaling the walls, soldiers working at the ramps were protected by shelters called vineae, that were arranged to form a long corridor. Wicker shields were used to protect the front of the corridor during its construction, another Roman siege engine sometimes used resembled the Greek ditch-filling tortoise, called a musculus. The Roman Legions first used siege towers around 200 BC, the first documented occurrence of ancient siege artillery pieces in Europe was the gastraphetes, a kind of large crossbow. These were mounted on wooden frames, greater machines forced the introduction of pulley system for loading the projectiles, which had extended to include stones also. Later torsion systems appeared, based on sinew springs, the onager was the main Roman invention in the field. Much of what we now know of the technology of the time came to us from Books 14 and 15 on Siege Warfare from the Mo Jing. Recorded and preserved on bamboo strips, much of the text is now unfortunately extremely corrupted, medieval designs include a large number of catapults such as the Mangonel, Onager, the ballista, the traction trebuchet, and the counterweight trebuchet. These machines used mechanical energy to fling large projectiles to batter down stone walls, also used were the battering ram and the siege tower, a wooden tower on wheels that allowed attackers to climb up and over castle walls, while protected somewhat from enemy arrows. Another weapon was the petard, a device designed specifically for breaching gates

German Empire
–
The German Empire was the historical German nation state that existed from the unification of Germany in 1871 to the abdication of Kaiser Wilhelm II in 1918, when Germany became a federal republic. The German Empire consisted of 26 constituent territories, with most being ruled by royal families and this included four kingdoms, six grand duchies, five duchies, seven principalities, three free Hanseatic cities, and one imperial territory. Although Prussia became one of kingdoms in the new realm, it contained most of its population and territory. Its influence also helped define modern German culture, after 1850, the states of Germany had rapidly become industrialized, with particular strengths in coal, iron, chemicals, and railways. In 1871, it had a population of 41 million people, and by 1913, a heavily rural collection of states in 1815, now united Germany became predominantly urban. During its 47 years of existence, the German Empire operated as an industrial, technological, Germany became a great power, boasting a rapidly growing rail network, the worlds strongest army, and a fast-growing industrial base. In less than a decade, its navy became second only to Britains Royal Navy, after the removal of Chancellor Otto von Bismarck by Wilhelm II, the Empire embarked on a bellicose new course that ultimately led to World War I. When the great crisis of 1914 arrived, the German Empire had two allies, Italy and the Austro-Hungarian Empire, Italy, however, left the once the First World War started in August 1914. In the First World War, German plans to capture Paris quickly in autumn 1914 failed, the Allied naval blockade caused severe shortages of food. Germany was repeatedly forced to send troops to bolster Austria and Turkey on other fronts, however, Germany had great success on the Eastern Front, it occupied large Eastern territories following the Treaty of Brest-Litovsk. German declaration of unrestricted submarine warfare in early 1917 was designed to strangle the British, it failed, but the declaration—along with the Zimmermann Telegram—did bring the United States into the war. Meanwhile, German civilians and soldiers had become war-weary and radicalised by the Russian Revolution and this failed, and by October the armies were in retreat, Austria-Hungary and the Ottoman Empire had collapsed, Bulgaria had surrendered and the German people had lost faith in their political system. The Empire collapsed in the November 1918 Revolution as the Emperor and all the ruling monarchs abdicated, and a republic took over. The German Confederation had been created by an act of the Congress of Vienna on 8 June 1815 as a result of the Napoleonic Wars, German nationalism rapidly shifted from its liberal and democratic character in 1848, called Pan-Germanism, to Prussian prime minister Otto von Bismarcks pragmatic Realpolitik. He envisioned a conservative, Prussian-dominated Germany, the war resulted in the Confederation being partially replaced by a North German Confederation in 1867, comprising the 22 states north of the Main. The new constitution and the title Emperor came into effect on 1 January 1871, during the Siege of Paris on 18 January 1871, William accepted to be proclaimed Emperor in the Hall of Mirrors at the Palace of Versailles. The second German Constitution was adopted by the Reichstag on 14 April 1871 and proclaimed by the Emperor on 16 April, the political system remained the same. The empire had a parliament called the Reichstag, which was elected by universal male suffrage, however, the original constituencies drawn in 1871 were never redrawn to reflect the growth of urban areas

Austria-Hungary
–
The union was a result of the Austro-Hungarian Compromise of 1867 and came into existence on 30 March 1867. Austria-Hungary consisted of two monarchies, and one region, the Kingdom of Croatia-Slavonia under the Hungarian crown. It was ruled by the House of Habsburg, and constituted the last phase in the evolution of the Habsburg Monarchy. Following the 1867 reforms, the Austrian and the Hungarian states were co-equal, Foreign affairs and the military came under joint oversight, but all other governmental faculties were divided between respective states. Austria-Hungary was a state and one of the worlds great powers at the time. Austria-Hungary was geographically the second-largest country in Europe after the Russian Empire, at 621,538 km2, the Empire built up the fourth-largest machine building industry of the world, after the United States, Germany, and the United Kingdom. After 1878, Bosnia and Herzegovina was under Austro-Hungarian military and civilian rule until it was annexed in 1908. The annexation of Bosnia also led to Islam being recognized as a state religion due to Bosnias Muslim population. Austria-Hungary was one of the Central Powers in World War I and it was already effectively dissolved by the time the military authorities signed the armistice of Villa Giusti on 3 November 1918. The realms full, official name was The Kingdoms and Lands Represented in the Imperial Council, each enjoyed considerable sovereignty with only a few joint affairs. Certain regions, such as Polish Galicia within Cisleithania and Croatia within Transleithania, enjoyed autonomous status, the division between Austria and Hungary was so marked that there was no common citizenship, one was either an Austrian citizen or a Hungarian citizen, never both. This also meant that there were always separate Austrian and Hungarian passports, however, neither Austrian nor Hungarian passports were used in the Kingdom of Croatia-Slavonia-Dalmatia. Instead, the Kingdom issued its own passports which were written in Croatian and French and it is not known what kind of passports were used in Bosnia-Herzegovina, which was under the control of both Austria and Hungary. The Kingdom of Hungary had always maintained a separate parliament, the Diet of Hungary, the administration and government of the Kingdom of Hungary remained largely untouched by the government structure of the overarching Austrian Empire. Hungarys central government structures remained well separated from the Austrian imperial government, the country was governed by the Council of Lieutenancy of Hungary – located in Pressburg and later in Pest – and by the Hungarian Royal Court Chancellery in Vienna. The Hungarian government and Hungarian parliament were suspended after the Hungarian revolution of 1848, despite Austria and Hungary sharing a common currency, they were fiscally sovereign and independent entities. Since the beginnings of the union, the government of the Kingdom of Hungary could preserve its separated. After the revolution of 1848–1849, the Hungarian budget was amalgamated with the Austrian, from 1527 to 1851, the Kingdom of Hungary maintained its own customs controls, which separated her from the other parts of the Habsburg-ruled territories

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

World War II
–
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the worlds countries—including all of the great powers—eventually forming two opposing alliances, the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. Marked by mass deaths of civilians, including the Holocaust and the bombing of industrial and population centres. These made World War II the deadliest conflict in human history, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific. The Axis advance halted in 1942 when Japan lost the critical Battle of Midway, near Hawaii, in 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained all of its territorial losses and invaded Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in South Central China and Burma, while the Allies crippled the Japanese Navy, thus ended the war in Asia, cementing the total victory of the Allies. World War II altered the political alignment and social structure of the world, the United Nations was established to foster international co-operation and prevent future conflicts. The victorious great powers—the United States, the Soviet Union, China, the United Kingdom, the Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next 46 years. Meanwhile, the influence of European great powers waned, while the decolonisation of Asia, most countries whose industries had been damaged moved towards economic recovery. Political integration, especially in Europe, emerged as an effort to end pre-war enmities, the start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland, Britain and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously and this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939, the exact date of the wars end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945, rather than the formal surrender of Japan

Krupp
–
The Krupp family, a prominent 400-year-old German dynasty from Essen, have become famous for their production of steel, artillery, ammunition, and other armaments. The family business, known as Friedrich Krupp AG, was the largest company in Europe at the beginning of the 20th century and it was important to weapons development and production in both world wars. One of the most powerful dynasties in European history, for 400 years Krupp flourished as the premier weapons manufacturer for Germany. From the Thirty Years War until the end of the Second World War, they produced everything from battleships, U-boats, tanks, howitzers, guns, utilities, the dynasty began in 1587 when a trader named Arndt Krupp moved to Essen and joined the merchants guild. He then began buying vacated real estate from families who fled the city due to the Black Death, over the next three centuries his descendants began producing small guns during the Thirty Years War and over time gradually acquired fulling mills, coal mines, and an iron forge. During the Napoleonic Wars, Friedrich Krupp founded the Gusstahlfabrik and began producing smelted steel in 1816, the foundations were laid for the steel Empire that would come to dominate the world for nearly a century under his son Alfred. Krupp became the manufacturer for the Kingdom of Prussia in 1859. Krupp was also a company that paved the way for workers rights. Widows and orphans were guaranteed pay if their husbands and/or fathers were killed, the company also produced the steel that built the railroads of America, capped the Chrysler Building in 1929, and was the first to travel to the bottom of the Mariana Trench. During the Third Reich, Krupp supported Adolf Hitler and the use of forced labour, after the war Krupp was rebuilt from scratch and again became one of the wealthiest companies in Europe. However a recession in 1967 caused the company severe profit loss, in 1999 the Krupp firm merged with Thyssen AG to form ThyssenKrupp AG, a large industrial conglomerate. Friedrich Krupp launched the familys metal-based activities, building a steel foundry in Essen in 1810. His son Alfred, known as the Cannon King or as Alfred the Great, invested heavily in new technology to become a significant manufacturer of steel rollers and he also invested in fluidized hotbed technologies and acquired many mines in Germany and France. Unusual for the era, he provided social services for his workers, including subsidized housing and health, the company began to make steel cannons in the 1840s—especially for the Russian, Turkish, and Prussian armies. When Alfred started with the firm, it had five employees, at his death twenty thousand people worked for Krupp—making it the worlds largest industrial company and the largest private company in the German empire. Krupps had a Great Krupp Building with an exhibition of guns at the Columbian Exposition in 1893, in the 20th century the company was headed by Gustav Krupp von Bohlen und Halbach, who assumed the surname of Krupp when he married the Krupp heiress, Bertha Krupp. After Adolf Hitler came to power in Germany in 1933, the Krupp works became the center for German rearmament. In 1943, by an order from Hitler, the company reverted to a sole-proprietorship, with Gustav

Pound (mass)
–
The pound or pound-mass is a unit of mass used in the imperial, United States customary and other systems of measurement. The international standard symbol for the pound is lb. The unit is descended from the Roman libra, the English word pound is cognate with, among others, German Pfund, Dutch pond, and Swedish pund. All ultimately derive from a borrowing into Proto-Germanic of the Latin expression lībra pondō, usage of the unqualified term pound reflects the historical conflation of mass and weight. This accounts for the modern distinguishing terms pound-mass and pound-force, the United States and countries of the Commonwealth of Nations agreed upon common definitions for the pound and the yard. Since 1 July 1959, the avoirdupois pound has been defined as exactly 0.45359237 kg. In the United Kingdom, the use of the pound was implemented in the Weights and Measures Act 1963.9144 metre exactly. An avoirdupois pound is equal to 16 avoirdupois ounces and to exactly 7,000 grains, the conversion factor between the kilogram and the international pound was therefore chosen to be divisible by 7, and an grain is thus equal to exactly 64.79891 milligrams. The US has not adopted the system despite many efforts to do so. Historically, in different parts of the world, at different points in time, and for different applications, the libra is an ancient Roman unit of mass that was equivalent to approximately 328.9 grams. It was divided into 12 unciae, or ounces, the libra is the origin of the abbreviation for pound, lb. A number of different definitions of the pound have historically used in Britain. Amongst these were the avoirdupois pound and the tower, merchants. Historically, the sterling was a tower pound of silver. In 1528, the standard was changed to the Troy pound, the avoirdupois pound, also known as the wool pound, first came into general use c. It was initially equal to 6992 troy grains, the pound avoirdupois was divided into 16 ounces. During the reign of Queen Elizabeth, the pound was redefined as 7,000 troy grains. Since then, the grain has often been a part of the avoirdupois system

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
