Mines In The Battle Of Messines (1917)
At the start of the Battle of Messines during the First World War, underground explosive charges were detonated by the British Second Army (General Sir Herbert Plumer) beneath the forward position of the German 4th Army near the village of Mesen (''Messines'' in French, historically used in English), in Belgian West Flanders. The mines, secretly planted by British tunnelling units, created craters and killed approximately 10,000 German soldiers. Their joint explosion ranks among the largest non-nuclear explosions of all time. The evening before the attack, General Sir Charles Harington, Chief of Staff of the Second Army, remarked to the press, "Gentlemen, I don’t know whether we are going to make history tomorrow, but at any rate we shall change geography". The Battle of Messines marked the zenith of mine warfare. On 10 August, the Royal Engineers fired the last British deep mine of the war, at Givenchy-en-Gohelle near Arras.

Battle Of Messines - Map
A battle is an occurrence of combat in warfare between opposing military units of any number or size. A war usually consists of multiple battles. In general, a battle is a military engagement that is well defined in duration, area, and force commitment. An engagement with only limited commitment between the forces and without decisive results is sometimes called a skirmish. The word "battle" can also be used infrequently to refer to an entire operational campaign, although this usage greatly diverges from its conventional or customary meaning. Generally, the word "battle" is used for such campaigns if referring to a protracted combat encounter in which either one or both of the combatants had the same methods, resources, and strategic objectives throughout the encounter. Some prominent examples of this would be the Battle of the Atlantic, Battle of Britain, and Battle of Stalingrad, all in World War II. Wars and military campaigns are guided by military strategy, whereas ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ypres Salient
The Ypres Salient around Ypres in Belgium was the scene of several battles and an extremely important part of the Western front during the First World War. Ypres district Ypres lies at the junction of the Ypres–Comines Canal and the Ieperlee. The city is overlooked by Kemmel Hill in the south-west and from the east by low hills running south-west to north-east with Wytschaete ( Wijtschate), Hill 60 to the east of Verbrandenmolen, Hooge, Polygon Wood and Passchendaele ( Passendale). The high point of the ridge is at Wytschaete, from Ypres, while at Hollebeke the ridge is distant and recedes to at Polygon Wood. Wytschaete is about above the plain; on the Ypres–Menin road at Hooge, the elevation is about and at Passchendaele. The rises are slight, apart from the vicinity of Zonnebeke, which has a From Hooge and to the east, the slope is near Hollebeke, it is heights are subtle but have the character of a saucer lip around Ypres.

175th Tunnelling Company
The 175th Tunnelling Company was one of the tunnelling companies of the Royal Engineers created by the British Army during World War I. The tunnelling units were occupied in offensive and defensive mining involving the placing and maintaining of mines under enemy lines, as well as other underground work such as the construction of deep dugouts for troop accommodation, the digging of subways, saps (a narrow trench dug to approach enemy trenches), cable trenches and underground chambers for signals and medical services.The Tunnelling Companies RE , access date 25 April 2015 Background By January 1915 it had become evident to the BEF at the |

Royal Engineers
The Corps of Royal Engineers, usually called the Royal Engineers (RE), and commonly known as the ''Sappers'', is a corps of the British Army. It provides military engineering and other technical support to the British Armed Forces and is headed by the Chief Royal Engineer. The Regimental Headquarters and the Royal School of Military Engineering are in Chatham in Kent, England. The corps is divided into several regiments, barracked at various places in the United Kingdom and around the world. History The Royal Engineers trace their origins back to the military engineers brought to England by William the Conqueror, specifically Bishop Gundulf of Rochester Cathedral, and claim over 900 years of unbroken service to the crown. Engineers have always served in the armies of the Crown; however, the origins of the modern corps, along with those of the Royal Artillery, lie in the Board of Ordnance established in the 15th century. In Woolwich in 1716, the Board formed the Royal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edgeworth David
Sir Tannatt William Edgeworth David (28 January 1858 – 28 August 1934) was a Welsh Australian geologist and Antarctic explorer. A household name in his lifetime, David's most significant achievements were discovering the major Hunter Valley coalfield in New South Wales and leading the first expedition to reach the South Magnetic Pole. He also served with distinction in World War I. Early life David was born on 28 January 1858, in St. Fagans near Cardiff, Wales, the eldest son of the Rev. William David, a fellow of Jesus College, Oxford, a classical scholar and naturalist and his wife Margaret Harriette (née Thomson). His mother's cousin, William A. E. Ussher of the Geological Survey, first interested David in what was to be his life work. At the age of 12, David went to Magdalen College School, Oxford in 1870. In 1876 he gained a classical scholarship to New College, Oxford. While there he was lectured by the famous John Ruskin and William Spooner. In 1878 he ...

Ground-water Table
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, permafros ...

Douve
The Douve () or Ouve is a river, in length, which rises in the commune of Tollevast, near Cherbourg in the department of Manche. ''Ouve'' is considered its old name (''Unva'' in ancient texts): Ouve appears to have been misspelled over the course of time as "Douve river" and then as "River of the Douve" (Douve literally means Ditch). The French name for this watercourse is ''la Douve''. After passing Tollevast, the river proceeds through the hills of the Cotentin peninsula (Cherbourg peninsula) and goes by Sottevast, l'Étang-Bertrand and Magneville. It borders Néhou and crosses Saint-Sauveur-le-Vicomte. Once it reaches Bauptois, it alters its direction towards the Bay of the Seine in the south-eastern English Channel, passing through Carentan. The Douve is a navigable river owing to its flat bottom and adequate depth of flow. In 1944 German troops, preparing Rommel's Fortress Europa, flooded the valley to prevent landing paratroops or gliders. On D-Day, the river was th ...

Tunnel
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
