Hydraulic Warfare
Hydraulic warfare (HW) is the use of water from reservoirs, rivers, canals, and other water features to impede the operations of an opposing force. This may involve breaching dams and rerouting watercourses. It can be used to impede the advance of an attacker or to reduce the resources and tactical options for defenders. The technique has been used to create "devastating floods, isolate troops, cut off supply lines, hinder river crossings, and disrupt military timetables". History Between the years 1500 and 2000, some 1/3 of floods in the Netherlands southwest were deliberately caused during wartime. The tactic was typically ineffective, and had damaged the land and local population. In 1938, China breached the dikes of the Yellow River to slow the advance of Japanese forces during the Second Sino-Japanese War. The flood became known as the largest such act in history. HW was used by Finland and the USSR during World War II. British forces destroyed the Moehne and Edersee Dam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water co ...

Battle Of Monte Cassino
The Battle of Monte Cassino, also known as the Battle for Rome and the Battle for Cassino, was a series of four assaults made by the Allies against German forces in Italy during the Italian Campaign of World War II. The ultimate objective was to break through the Winter Line, and facilitate an advance towards Rome. At the beginning of 1944, the western half of the Winter Line was anchored by Germans holding the Rapido-Gari, Liri and Garigliano valleys and several of the surrounding peaks and ridges. Together, these features formed the Gustav Line. Monte Cassino, a historic hilltop abbey founded in 529 by the Benedict of Nursia, dominated the nearby town of Cassino and the entrances to the Liri and Rapido valleys. Lying in a protected historic zone, it had been left unoccupied by the Germans, although they manned some positions set into the slopes below the abbey's walls. Repeated artillery attacks on assaulting allied troops caused their leaders to conclude incorrectly that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Garigliano
The Garigliano () is a river in central Italy. It forms at the confluence of the rivers Gari (also known as the Rapido) and Liri. Garigliano is actually a deformation of "Gari-Lirano" (which in Italian means something like "Gari from the Liri"). In ancient times the whole course of the Liri and Garigliano was known as the ''Liris''. For the most part of its length, the Garigliano River marks the border between the Italian regions of Lazio and Campania. In medieval times, the river (then known as the ''Verde'') marked the southern border of the Papal States. Historical significance Western Roman Emperor Majorian engaged a Vandal raiding party in Battle at Garigliano in 457 In the 9th and early 10th centuries, a band of Saracens established themselves on the banks of the Garigliano, from where they launched frequent raids on Campania and central Italy. In 915 a coalition of the pope, the Byzantines, Franks, Lombards, and Naples defeated the Garigliano Arabs in the Battle of G ...

Liri
The Liri (Latin Liris or Lyris, previously, Clanis; Greek: ) is one of the principal rivers of central Italy, flowing into the Tyrrhenian Sea a little below Minturno under the name Garigliano. Source and route The Liri's source is in the Monte Camiciola, elevation , in the Monti Simbruini of central Apennines (Abruzzo, ''comune'' of Cappadocia). It flows at first in a southeasterly direction through a long trough-like valley, parallel to the general direction of the Apennines, until it reaches the city of Sora. In the upper part of Isola del Liri it receives the waters of Fibreno and then it divides into two branches which then rejoin, surrounding the lower part of the town (''Isola del Liri'' stands for ''Liri Island''). One branch makes a high waterfall situated in the centre, a unique case in Europe. A dam is built on the river after the confluence with the Sacco at Ceprano. The last important Liri's tributary is the Melfa, with which it joins near Aquino. After Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It incorporates a dictatorship, fervent antisemitism, anti-communism, scientific racism, and the use of eugenics into its creed. Its extreme nationalism originated in pan-Germanism and the ethno-nationalist '' Völkisch'' movement which had been a prominent aspect of German nationalism since the late 19th century, and it was strongly influenced by the paramilitary groups that ...
