Gas Attacks At Hulluch
The Gas Attacks at Hulluch were two German cloud gas attacks on British troops during World War I, from 27 to 29 April 1916, near the village of Hulluch, north of Loos in northern France. The gas attacks were part of an engagement between divisions of the II Royal Bavarian Corps and divisions of the British I Corps. Just before dawn on 27 April, the 16th (Irish) Division and part of the 15th (Scottish) Division were subjected to a cloud gas attack near Hulluch. The gas cloud and artillery bombardment were followed by raiding parties, which made temporary lodgements in the British lines. Two days later the Germans began another gas attack but the wind turned and blew the gas back over the German lines. A large number of German casualties were caused by the change in the wind direction and the decision to go ahead despite protests by local officers. German casualties were increased by the British, who fired on German soldiers as they fled in the open. The gas used by the Ger ...

Western Front (World War I)
The Western Front was one of the main theatres of war during the First World War. Following the outbreak of war in August 1914, the German Army opened the Western Front by invading Luxembourg and Belgium, then gaining military control of important industrial regions in France. The German advance was halted with the Battle of the Marne. Following the Race to the Sea, both sides dug in along a meandering line of fortified trenches, stretching from the North Sea to the Swiss frontier with France, which changed little except during early 1917 and in 1918. Between 1915 and 1917 there were several offensives along this front. The attacks employed massive artillery bombardments and massed infantry advances. Entrenchments, machine gun emplacements, barbed wire and artillery repeatedly inflicted severe casualties during attacks and counter-attacks and no significant advances were made. Among the most costly of these offensives were the Battle of Verdun, in 1916, with a combined 700,000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phosgene
Phosgene is the organic chemical compound with the formula COCl2. It is a toxic, colorless gas; in low concentrations, its musty odor resembles that of freshly cut hay or grass. Phosgene is a valued and important industrial building block, especially for the production of precursors of polyurethanes and polycarbonate plastics. Phosgene is extremely poisonous and was used as a chemical weapon during World War I, where it was responsible for 85,000 deaths. It was a highly potent pulmonary irritant and quickly filled enemy trenches due to it being a heavy gas. It is classified as a Schedule 3 substance under the Chemical Weapons Convention. In addition to its industrial production, small amounts occur from the breakdown and the combustion of organochlorine compounds, such as chloroform. Structure and basic properties Phosgene is a planar molecule as predicted by VSEPR theory. The C=O distance is 1.18 Å, the C−Cl distance is 1.74 Å and the Cl−C−Cl angle is 111 ...

3rd Royal Bavarian Division
The 3rd Royal Bavarian Division was a unit of the Royal Bavarian Army which served alongside the Prussian Army as part of the Imperial German Army. The division was formed on November 27, 1815, as an Infantry Division of the Würzburg General Command (''Infanterie-Division des Generalkommandos Würzburg''). It was called the 3rd Army Division between 1822 and 1848, again between 1851 and 1859, and again from 1869 to 1872. It was called the 3rd Infantry Division from 1848 to 1851 (as well as during wartime) and was named the Nuremberg General Command from 1859 to 1869. From April 1, 1872, until mobilization for World War I, it was the 3rd Division.Wegner, p. 663; Bredow, pp. 1246, 1252. In 1901, it had swapped division numbers with the 5th Division. In Bavarian sources, it was not generally referred to as a "Royal Bavarian" division, as this was considered self-evident, but outside Bavaria, this designation was used for it, and other Bavarian units, to distinguish them from simi ...

Parts-per Notation
In science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement. Commonly used are parts-per-million (ppm, ), parts-per-billion (ppb, ), parts-per-trillion (ppt, ) and parts-per-quadrillion (ppq, ). This notation is not part of the International System of Units (SI) system and its meaning is ambiguous. Overview Parts-per notation is often used describing dilute solutions in chemistry, for instance, the relative abundance of dissolved minerals or pollutants in water. The quantity "1 ppm" can be used for a mass fraction if a water-borne pollutant is present at one-millionth of a gram per gram of sample solution. When working with aqueous solutions, it is common to assume that the density of water is 1.00 g/mL. Therefore, it is common to equat ...

Battle Of The Hohenzollern Redoubt
The actions of the Hohenzollern Redoubt took place on the Western Front in World War I from 13 to 19 October 1915, at the Hohenzollern Redoubt () near Auchy-les-Mines in France. In the aftermath of the Battle of Loos (25 September – 8 October 1915), the 9th (Scottish) Division captured the strongpoint and then lost it to a German counter-attack. The British attack on 13 October failed and resulted in mostly in the first few minutes. In the History of the Great War, James Edmonds wrote that "The fighting rom 13 to 14 Octoberhad not improved the general situation in any way and had brought nothing but useless slaughter of infantry". Background Strategic developments In the summer of 1915 the German armies continued the strengthening of front trenches, communication trenches and strong-points ordered by Chief of the General Staff General Erich von Falkenhayn, who on 25 January had also ordered the building of more defensive lines behind the front trench.

History Of The British 1st Division During The World Wars
The 1st Division was an infantry division of the British Army that was formed and disestablished numerous times between 1809 and the present. It was raised by Lieutenant-General Arthur Wellesley for service in the Peninsular War (part of the Coalition Wars of the Napoleonic Wars). It was disestablished in 1814 but re-formed the following year for service in the War of the Seventh Coalition and fought at the Battle of Waterloo. It remained active in France until 1818, when it was disbanded. It was subsequently raised for service in the Crimean War, the Anglo-Zulu War, and the Second Boer War. In 1902, it was re-raised in the UK. This latter event saw the division raised as a permanent formation, rather than being formed on an ad hoc basis for any particular crisis. In 1914, the First World War broke out and the division fought on the Western Front throughout the entire period. In 1919, it was used to form the Western Division as part of the British Army of the Rhine occupation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

12th (Eastern) Division
The 12th (Eastern) Division was an infantry division raised by the British Army during the First World War from men volunteering for Kitchener's New Armies. The division saw service in the trenches of the Western Front from June 1915 to the end of the war. Formation and First World War The 12th (Eastern) Division, was one of the first Kitchener's Army divisions raised from volunteers by Lord Kitchener. It was formed within Eastern Command as a result of Army Order No. 324 of 21 August 1914, as part of the K1 wave of divisions. It fought on the Western Front for the duration of the First World War. One of its most notable actions was the Battle of Épehy where there is a memorial cross to the 12th Division. In the First World War, the division's insignia was the Ace of Spades, which has since been adopted by the present 12th Armoured Infantry Brigade.

Battle Of Loos
The Battle of Loos took place from 1915 in France on the Western Front, during the First World War. It was the biggest British attack of 1915, the first time that the British used poison gas and the first mass engagement of New Army units. The French and British tried to break through the German defences in Artois and Champagne and restore a war of movement. Despite improved methods, more ammunition and better equipment, the Franco-British attacks were largely contained by the Germans, except for local losses of ground. The British gas attack failed to neutralize the defenders and the artillery bombardment was too short to destroy the barbed wire or machine gun nests. German tactical defensive proficiency was still dramatically superior to the British offensive planning and doctrine, resulting in a British defeat. Background Strategic developments The battle was the British part of the Third Battle of Artois, an Anglo-French offensive (known to the Germans as the (Autumn Batt ...

No Man's Land
No man's land is waste or unowned land or an uninhabited or desolate area that may be under dispute between parties who leave it unoccupied out of fear or uncertainty. The term was originally used to define a contested territory or a dumping ground for refuse between fiefdoms. In modern times, it is commonly associated with World War I to describe the area of land between two enemy trench systems, not controlled by either side. Coleman p. 268 The term is also used metaphorically, to refer to an ambiguous, anomalous, or indefinite area, in regards to an application, situation, or jurisdiction. It has sometimes been used to name a specific place. Origin According to Alasdair Pinkerton, an expert in human geography at Royal Holloway, University of London, the term is first mentioned in Domesday Book (1086), to describe parcels of land that were just beyond the London city walls. The ''Oxford English Dictionary'' contains a reference to the term dating back to 1320, spell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cadre (military)
A cadre (, , ) is the complement of commissioned officers and non-commissioned officers of a military unit responsible for training the rest of the unit. The cadre may be the permanent skeleton establishment of a unit, around which the full unit can be built if needed. In countries which have conscription, a cadre may comprise the permanent staff of a regiment who train the conscripts assigned to it. The term comes from the French expression ''en cadre'', with the same meaning. In the Military of the United States, a cadre is a group or member of a group of leaders, especially in units that conduct formal training schools. In United States Army jargon, the word is singular and plural. At the United States Military Academy, the upper-class cadets who conduct Cadet Basic Training for incoming freshmen are called the cadre. In the British Armed Forces, a cadre is a group of instructors or a unit that trains potential instructors or non-commissioned officers (NCOs), in which case i ...
