Royal Engineer Tunnelling Companies
Royal Engineer tunnelling companies were specialist units of the Corps of Royal Engineers within the British Army, formed to dig attacking tunnels under enemy lines during the First World War. The stalemate situation in the early part of the war led to the deployment of tunnel warfare. After the first German Empire attacks on 21 December 1914, through shallow tunnels underneath no man's land and exploding ten mines under the trenches of the Indian Sirhind Brigade, the British began forming suitable units. In February 1915, eight Tunnelling Companies were created and operational in Flanders from March 1915. By mid-1916, the British Army had around 25,000 trained tunnellers, mostly volunteers taken from coal mining communities. Almost twice that number of "attached infantry" worked permanently alongside the trained miners acting as 'beasts of burden'. From the spring of 1917 the whole war became more mobile, with grand offensives at Arras, Messines and Passchendaele. There was ...

Flag Of The British Army
A flag is a piece of fabric (most often rectangular or quadrilateral) with a distinctive design and colours. It is used as a symbol, a signalling device, or for decoration. The term ''flag'' is also used to refer to the graphic design employed, and flags have evolved into a general tool for rudimentary signalling and identification, especially in environments where communication is challenging (such as the maritime environment, where semaphore is used). Many flags fall into groups of similar designs called flag families. The study of flags is known as "vexillology" from the Latin , meaning "flag" or "banner". National flags are patriotic symbols with widely varied interpretations that often include strong military associations because of their original and ongoing use for that purpose. Flags are also used in messaging, advertising, or for decorative purposes. Some military units are called "flags" after their use of flags. A ''flag'' (Arabic: ) is equivalent to a brigade ...

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] |
Ambracia
Ambracia (; grc-gre, Ἀμβρακία, occasionally , ''Ampracia'') was a city of ancient Greece on the site of modern Arta. It was captured by the Corinthians in 625 BC and was situated about from the Ambracian Gulf, on a bend of the navigable river Arachthos (or Aratthus), in the midst of a fertile wooded plain. History Ambracia was founded between 650 and 625 BC by Gorgus, son of the Corinthian tyrant Cypselus, at which time its economy was based on farmlands, fishing, timber for shipbuilding, and the exportation of the produce of Epirus. After the expulsion of Gorgus's son Periander its government developed into a strong democracy. The early policy of Ambracia was determined by its loyalty to Corinth (for which it probably served as an entrepot in the Epirus trade), and its consequent aversion to Corcyra (as Ambracia participated on the Corinthian side at the Battle of Sybota, which took place in 433 BC between the rebellious Corinthian colony of Corcyra (modern Corfu) and ...

The Histories (Polybius)
Polybius’ ''Histories'' ( grc-gre, Ἱστορίαι ''Historíai'') were originally written in 40 volumes, only the first five of which are extant in their entirety. The bulk of the work was passed down through collections of excerpts kept in libraries in the Byzantine Empire. Polybius, a historian from the Greek city of Megalopolis in Arcadia, was taken as a hostage to Rome after the Roman victory in the Third Macedonian War (171–168 BC), and there he began to write an account of the rise of Rome to a great power. Content Polybius' ''Histories'' begin in the year 264 BC and end in 146 BC (Polybius was born around 200 BC and died around 117 BC). He is primarily concerned with the 53 years in which Ancient Rome became a dominant world power. This period, from 220–167 BC, saw Rome subjugate Carthage and gain control over Hellenistic Greece. Books I through V cover the affairs of important states at the time (Ptolemaic Egypt, Hellenistic Greece, Macedon) and deal extensiv ...

Polybius
Polybius (; grc-gre, Πολύβιος, ; ) was a Greek historian of the Hellenistic period. He is noted for his work , which covered the period of 264–146 BC and the Punic Wars in detail. Polybius is important for his analysis of the mixed constitution or the separation of powers in government, his in-depth discussion of checks and balances to limit power, and his introduction of "the people", which influenced Montesquieu's ''The Spirit of the Laws'', John Locke's ''Two Treatises of Government'', and the framers of the United States Constitution. The leading expert on Polybius for nearly a century was F. W. Walbank (1909–2008), who published studies related to him for 50 years, including a long commentary of his ''Histories'' and a biography. Early life Polybius was born around 200 BC in Megalopolis, Greece, Megalopolis, Arcadia (region), Arcadia, when it was an active member of the Achaean League. The town was revived, along with other Achaean states, a century before he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Siege Warfare
A siege is a military blockade of a city, or fortress, with the intent of conquering by attrition, or a well-prepared assault. This derives from la, sedere, lit=to sit. Siege warfare is a form of constant, low-intensity conflict characterized by one party holding a strong, static, defensive position. Consequently, an opportunity for negotiation between combatants is common, as proximity and fluctuating advantage can encourage diplomacy. The art of conducting and resisting sieges is called siege warfare, siegecraft, or poliorcetics. A siege occurs when an attacker encounters a city or fortress that cannot be easily taken by a quick assault, and which refuses to surrender. Sieges involve surrounding the target to block the provision of supplies and the reinforcement or escape of troops (a tactic known as "investment"). This is typically coupled with attempts to reduce the fortifications by means of siege engines, artillery bombardment, mining (also known as sapping), or the use ...

Dugout (military)
A dugout or dug-out, also known as a pit-house or earth lodge, is a shelter for humans or domesticated animals and livestock based on a hole or depression dug into the ground. Dugouts can be fully recessed into the earth, with a flat roof covered by ground, or dug into a hillside. They can also be semi-recessed, with a constructed wood or sod roof standing out. These structures are one of the most ancient types of human housing known to archaeologists, and the same methods have evolved into modern "earth shelter" technology. Dugouts may also be temporary shelters constructed as an aid to specific activities, e.g., concealment and protection during warfare or shelter while hunting.

Battle Of Passchendaele
The Third Battle of Ypres (german: link=no, Dritte Flandernschlacht; french: link=no, Troisième Bataille des Flandres; nl, Derde Slag om Ieper), also known as the Battle of Passchendaele (), was a campaign of the First World War, fought by the Allies against the German Empire. The battle took place on the Western Front, from July to November 1917, for control of the ridges south and east of the Belgian city of Ypres in West Flanders, as part of a strategy decided by the Allies at conferences in November 1916 and May 1917. Passchendaele lies on the last ridge east of Ypres, from Roulers (now Roeselare), a junction of the Bruges-(Brugge)-to-Kortrijk railway. The station at Roulers was on the main supply route of the German 4th Army. Once Passchendaele Ridge had been captured, the Allied advance was to continue to a line from Thourout (now Torhout) to Couckelaere (Koekelare). Further operations and a British supporting attack along the Belgian coast from Nieuport ( Nieuwpoo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Mining
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit', and the above-ground structures are a 'pit head'. In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments in recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open-cut and longwall mines. Mining at this scale requires the use of draglines, trucks, conveyors, hydraulic jacks and shearers. The coal mining industry has a long history of significant negative environmental impacts on local ecosystems, health impacts on local communities and workers, and contributes heavily to th ...
