Hindenberg Line
The Hindenburg Line (German: , Siegfried Position) was a German Defense line, defensive position built during the winter of 1916–1917 on the Western Front (World War I), Western Front during the First World War. The line ran from Arras to Laffaux, near Soissons on the Aisne River, Aisne. In 1916, the Battle of Verdun and the Battle of the Somme left the German western armies () exhausted and on the Eastern Front (World War I), Eastern Front, the Brusilov Offensive had inflicted huge losses on the Austro-Hungarian armies and forced the Germans to take over more of the front. The declaration of war by Romania during World War I, Romania had placed additional strain on the German army and war economy. The Hindenburg Line, built behind the Noyon Salient (territory), Salient, was to replace the old front line as a precaution against a resumption of the Battle of the Somme in 1917. By wasting the intervening ground, the Germans could delay a spring offensive in 1917. A shortened fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sigurd
Sigurd ( non, Sigurðr ) or Siegfried (Middle High German: ''Sîvrit'') is a legendary hero of Germanic heroic legend, who killed a dragon and was later murdered. It is possible he was inspired by one or more figures from the Frankish Merovingian dynasty, with Sigebert I being the most popular contender. Older scholarship sometimes connected him with Arminius, victor of the Battle of the Teutoburg Forest. He may also have a purely mythological origin. Sigurd's story is first attested on a series of carvings, including runestones from Sweden and stone crosses from the British Isles, dating from the eleventh century. In both the Norse and continental Germanic tradition, Sigurd is portrayed as dying as the result of a quarrel between his wife ( Gudrun/Kriemhild) and another woman, Brunhild, whom he has tricked into marrying the Burgundian king Gunnar/Gunther. His slaying of a dragon and possession of the hoard of the Nibelungen is also common to both traditions. In other respect ...

Eastern Front (World War I)
The Eastern Front or Eastern Theater of World War I (german: Ostfront; ro, Frontul de răsărit; russian: Восточный фронт, Vostochny front) was a theater (warfare), theater of operations that encompassed at its greatest extent the entire frontier between Russian Empire, Russia and Kingdom of Romania, Romania on one side and Austria-Hungary, Kingdom of Bulgaria, Bulgaria, the Ottoman Empire, Ottoman Empire, and German Empire, Germany on the other. It stretched from the Baltic Sea in the north to the Black Sea in the south, involved most of Eastern Europe, and stretched deep into Central Europe as well. The term contrasts with "Western Front (World War I), Western Front", which was being fought in Belgium and French Third Republic, France. During 1910, Russian General Yuri Danilov developed "Plan 19" under which four armies would invade East Prussia. This plan was criticised as Austria-Hungary could be a greater threat than the German Empire. So instead of four arm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IX Reserve Corps (German Empire)
The IX Reserve Corps (german: IX. Reserve-Korps / IX RK) was a corps level command of the German Army in World War I. Formation IX Reserve Corps was formed on the outbreak of the war in August 1914 as part of the mobilisation of the Army.

Map Of The Battle Of The Somme, 1916
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. Thus, "map" became a shortened term referring to ...

Hundred Days Offensive
The Hundred Days Offensive (8 August to 11 November 1918) was a series of massive Allies of World War I, Allied offensives that ended the First World War. Beginning with the Battle of Amiens (1918), Battle of Amiens (8–12 August) on the Western Front (World War I), Western Front, the Allies pushed the Central Powers back, undoing their gains from the German spring offensive. The Germans retreated to the Hindenburg Line, but the Allies broke through the line with a series of victories, starting with the Battle of St Quentin Canal on 29 September. The offensive, together with a German Revolution of 1918–19, revolution breaking out in Germany, led to the Armistice of 11 November 1918 which ended the war with an Allied victory. The term "Hundred Days Offensive" does not refer to a battle or strategy, but rather the rapid series of Allied victories against which the German Army (German Empire), German Army had no reply.

Hindenburg Programme
The Hindenburg Programme of August 1916 is the name given to the armaments and economic policy begun in late 1916 by the Third (OHL, headquarters of the German General Staff), Field Marshal Paul von Hindenburg and General Erich Ludendorff. The two were appointed after the sacking of General Erich von Falkenhayn on 28 August 1916 and intended to double German industrial production, to greatly increase the output of munitions and weapons. Background Third OHL On 29 August 1916, Field Marshal Paul von Hindenburg and General Erich Ludendorff were appointed as heads of (OHL, German General Staff) of the German army, after the sacking of General Erich von Falkenhayn, who had commanded the armies of Germany since September 1914.

Strategic Bombing During World War I
Strategic bombing during World War I (28 July 1914 – 11 November 1918) was principally carried out by the United Kingdom and France for the Entente Powers and Germany for the Central Powers. All the belligerents of World War I eventually engaged in strategic bombing, and, with the exception only of Rome and Lisbon, the capital cities of all the major European belligerents were targeted. A multi-national air force to strike at Germany was planned but never materialized. The aerial bombing of cities, intended to destroy the enemy's morale, was introduced by the Germans in the opening days of the war. Early strategic bombing attempts led to the development of specialized bomber aircraft, during World War I. Initially bombs were dropped by hand and aimed by the naked eye, but by the end of the war bombsights had been developed. The introduction of air raid warnings and shelters can be dated to World War I, as can the design of anti-aircraft artillery and the development of method ...

Unrestricted Submarine Warfare
Unrestricted submarine warfare is a type of naval warfare in which submarines sink merchant ships such as freighters and tankers without warning, as opposed to attacks per prize rules (also known as "cruiser rules") that call for warships to search merchantmen and place crews in "a place of safety" (for which lifeboats do not qualify, except under particular circumstances) before sinking them, unless the ship shows "persistent refusal to stop ... or active resistance to visit or search". To follow the rules a submarine must surface, defeating the purpose of submarines and putting itself in danger of attack. History Limitations on warfare at sea date back to the 1899 Hague Convention. During the First World War, the United Kingdom introduced Q-ships with concealed deck guns and many armed merchantmen, leading Germany to ignore the prize rules. In the most dramatic episode they sank in 1915 in a few minutes because she was carrying war munitions. The U.S. demanded it stop, and ...

Camouflage
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate, as well as making general aiming easier. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Defence In Depth
Defence in depth (also known as deep defence or elastic defence) is a military strategy that seeks to delay rather than prevent the advance of an attacker, buying time and causing additional casualties by yielding space. Rather than defeating an attacker with a single, strong defensive line, defence in depth relies on the tendency of an attack to lose momentum over time or as it covers a larger area. A defender can thus yield lightly defended territory in an effort to stress an attacker's logistics or spread out a numerically superior attacking force. Once an attacker has lost momentum or is forced to spread out to pacify a large area, defensive counter-attacks can be mounted on the attacker's weak points, with the goal being to cause attrition or drive the attacker back to its original starting position. Strategy A conventional defence strategy would concentrate all military resources at a front line, which, if breached by an attacker, would leave the remaining defenders in d ...

Reverse Slope Defence
A reverse slope defence is a military tactic where a defending force is positioned on the slope of an elevated terrain feature such as a hill, ridge, or mountain, on the side opposite from the attacking force. This tactic both hinders the attacker's ability to observe the defender's positions and reduces the effectiveness of the attacker's long-range weapons such as tanks and artillery. A defending unit usually does not conduct a reverse-slope defence along its entire front, as positioning troops on the forward slope is necessary to control the region in front of the hill. However, when enemy forces are known to have superior long-range direct-fire or indirect-fire weapons, the majority of the defending force can use the hill to limit enemy observation and reduce the effectiveness of the long-range enemy fire. This tactic may even succeed in deceiving the enemy as to the true location and organisation of the main defensive positions. Typically, a smaller unit is still posted on th ...
