Cohorn
A Coehorn (also spelled ''cohorn'') is a lightweight mortar originally designed by Dutch military engineer Menno van Coehoorn. Concept and design Van Coehoorn came to prominence during the 1688–97 Nine Years War, whose tactics have been summarised by historian John Childs as follows: "The majority of infantrymen never fired their muskets in anger;....armies were consciously geared towards the dominant forms of warfare; manoeuvre and the siege." This emphasis on siege warfare saw many developments in the use and design of artillery. Fortifications were vulnerable to vertical trajectory or plunging fire, and the concept of mortars was well understood, but large scale mortars were commonly used initially to provide close support for infantry assaults on fortified positions. Van Coehoorn demonstrated them in May 1701 to William III of England, and they were first used in action at the siege of Kaiserswerth in 1702. The original was light enough to be moved by as few as tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Siege Artillery In The American Civil War
Siege artillery is heavy artillery primarily used in military attacks on fortified positions. At the time of the American Civil War, the U.S. Army classified its artillery into three types, depending on the gun's weight and intended use. ''Field artillery'' were light pieces that often traveled with the armies. ''Siege and garrison artillery'' were heavy pieces that could be used either in attacking or defending fortified places. ''Seacoast artillery'' were the heaviest pieces and were intended to be used in permanent fortifications along the seaboard. They were primarily designed to fire on attacking warships . The distinctions are somewhat arbitrary, as field, siege and garrison, and seacoast artillery were all used in various attacks and defenses of fortifications. This article will focus on the use of heavy artillery in the attack of fortified places during the American Civil War. The weight and size of siege artillery prevented it from regularly travelling with the armies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vue Pa Chay's Revolt
Vue Pa Chay's revolt, also called War of the Insane or the Madman's War (''Guerre du Fou'') by French sources, was a Hmong revolt against taxation in the French colonial administration in Indochina lasting from 1918 to 1921. Vue Pa Chay, the leader of the revolt, regularly climbed trees to receive military orders from heaven. The French granted the Hmong a special status in 1920, effectively ending the conflict.Fadiman, Anne. ''The Spirit Catches You and You Fall Down''. The Noonday Press. 1997. 17. The stimulus for the rebellion was heavy taxation by the French and abuse of power by the ethnic Lao and Tai tax collectors. The Hmong people were divided into pro-French and anti-French factions. The rebellion, called "Rog Paj Cai" by the Hmong nationalists and "Rog Phim Npab" by Hmong who sided with the French, was a self-initiated and self-sustaining movement. All guns were Hmong-designed and manufactured flintlocks, which were slightly different from the traditional western flin ...

Hmong People
The Hmong people ( RPA: ''Hmoob'', Nyiakeng Puachue: , Pahawh Hmong: , ) are a sub-ethnic group of the Miao people who originated from Central China. The modern Hmongs presently reside mainly in Southwest China (Guizhou, Yunnan, Sichuan, Chongqing, and Guangxi) and countries in Southeast Asia such as Vietnam, Laos, Thailand, and Myanmar. There is also a very large diasporic community in the United States, comprising more than 300,000 Hmong. The Hmong diaspora also has smaller communities in Australia and South America (specifically Argentina and French Guiana, the latter being an overseas region of France). During the First and Second Indo-China Wars, France and the United States intervened in the Lao Civil War by recruiting thousands of Hmong people to fight against forces from North and South Vietnam, which were stationed in Laos in accordance with their mission to support the communist Pathet Lao insurgents. The CIA operation is known as the Secret War. Etymol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Aubers
The Battle of Aubers (Battle of Aubers Ridge) was a British offensive on the Western Front on 9 May 1915 during the First World War. The battle was part of the British contribution to the Second Battle of Artois, a Franco-British offensive intended to exploit the German diversion of troops to the Eastern Front. The French Tenth Army was to attack the German 6th Army north of Arras and capture Vimy Ridge, preparatory to an advance on Cambrai and Douai. The British First Army, on the left (northern) flank of the Tenth Army, was to attack on the same day and widen the gap in the German defences expected to be made by the Tenth Army and to fix German troops north of La Bassée Canal. The attack was an unmitigated disaster on the part of the British. No ground was gained, no tactical advantage was gained, and they suffered more than ten times the number of casualties as the Germans. To make matters worse the battle precipitated a political crisis back home, which became the Shell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Neuve Chapelle
The Battle of Neuve Chapelle (10–13 March 1915) took place in the First World War in the Artois region of France. The attack was intended to cause a rupture in the German lines, which would then be exploited with a rush to the Aubers Ridge and possibly Lille. A French assault at Vimy Ridge on the Artois plateau was also planned to threaten the road, rail and canal junctions at La Bassée from the south as the British attacked from the north. The British attackers broke through German defences in a salient at the village of Neuve-Chapelle but the success could not be exploited. If the French Tenth Army captured Vimy Ridge and the north end of the Artois plateau, from Lens to La Bassée, as the First Army took Aubers Ridge from La Bassée to Lille, a further advance of would cut the roads and railways used by the Germans, to supply the troops in the Noyon Salient from Arras south to Rheims. The French part of the offensive was cancelled when the British were unable to relieve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Minenwerfer
''Minenwerfer'' ("mine launcher" or "mine thrower") is the German name for a class of short range mine shell launching mortars used extensively during the First World War by the Imperial German Army. The weapons were intended to be used by engineers to clear obstacles including bunkers and barbed wire, that longer range artillery would not be able to target accurately. Background The Germans studied the Siege of Port Arthur, where heavy artillery had been unable to destroy defensive structures like barbed wire and bunkers. The German Military ''Ingenieurkomitee'' ("Engineer committee") began working with Rheinmetall to study the problem in 1907. The solution they developed was a short-barrelled rifled muzzle-loading mortar for mine shell ammunition, built in three sizes. In 1910, the largest of these was introduced as the ''25 cm schwerer Minenwerfer'' (abbreviated "sMW"; English: "25 cm heavy mine launcher"). Despite weighing only 955 kg (2,193 pounds), it had the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trench Warfare
Trench warfare is a type of land warfare using occupied lines largely comprising military trenches, in which troops are well-protected from the enemy's small arms fire and are substantially sheltered from artillery. Trench warfare became archetypically associated with World War I (1914–1918), when the Race to the Sea rapidly expanded trench use on the Western Front starting in September 1914.. Trench warfare proliferated when a revolution in firepower was not matched by similar advances in mobility, resulting in a grueling form of warfare in which the defender held the advantage. On the Western Front in 1914–1918, both sides constructed elaborate trench, underground, and dugout systems opposing each other along a front, protected from assault by barbed wire. The area between opposing trench lines (known as " no man's land") was fully exposed to artillery fire from both sides. Attacks, even if successful, often sustained severe casualties. The development of armoured ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
