8-inch Gun M1
The 8-inch gun M1 was a 203 mm towed heavy gun developed in the United States. At 32,584 m (35,635 yd), it had the longest range of any United States Army, US Army field artillery weapon in World War II. It was also used in small numbers by the British Army during the Second World War, British Army. Development and production In 1919, the Westervelt Board, named for its president, Brigadier General William I. Westervelt, described the ideal heavy gun for future development having a bore of 194 mm to 8 inches, a projectile of about 200 lbs in weight, and a range of 35,000 yards. More striking was the requirement that it be road transportable. At this time no other country had such a road-transportable heavy field gun. Low-priority design work occurred until 1924. Serious development restarted in June 1940, resulting in an 8-inch (203 mm) gun that would have a range of , be transported in two loads weighing no more than at a road speed of up to , ...

8 Inch Gun 2
8 (eight) is the natural number following 7 and preceding 9. Etymology English ''eight'', from Old English '', æhta'', Proto-Germanic ''*ahto'' is a direct continuation of Proto-Indo-European '' *oḱtṓ(w)-'', and as such cognate with Greek and Latin , both of which stems are reflected by the English prefix oct(o)-, as in the ordinal adjective ''octaval'' or ''octavary'', the distributive adjective is ''octonary''. The adjective ''octuple'' (Latin ) may also be used as a noun, meaning "a set of eight items"; the diminutive ''octuplet'' is mostly used to refer to eight siblings delivered in one birth. The Semitic numeral is based on a root ''*θmn-'', whence Akkadian ''smn-'', Arabic ''ṯmn-'', Hebrew ''šmn-'' etc. The Chinese numeral, written (Mandarin: ''bā''; Cantonese: ''baat''), is from Old Chinese ''*priāt-'', ultimately from Sino-Tibetan ''b-r-gyat'' or ''b-g-ryat'' which also yielded Tibetan '' brgyat''. It has been argued that, as the cardinal num ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roer River
The Roer (, ) or Rur (; ) is a major river that flows through portions of Belgium, Germany and the Netherlands. It is a right (eastern) tributary to the Meuse (). About 90 percent of the river's course is in Germany. It is not to be confused with the rivers Ruhr and Röhr, which are tributaries of the Rhine in North Rhine-Westphalia. History During the Middle Ages the valley of the Roer lay mostly within the Duchy of Jülich. In 1795, until 1814, during which time the area was part of the French Republic and Empire, it gave its name to the French ''département'' of the Roer. The Roer represented an important front in the Allied push towards Germany at the end of the Second World War. A fortified area known as the Roer Triangle, formed by the towns of Roermond and Sittard, in the Netherlands, and Heinsberg in Germany, was the scene of heavy fighting at the beginning of 1945. Operation Blackcock was the code name for the clearing of the Roer Triangle. It was conduct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siegfried Line
The Siegfried Line, known in German as the ''Westwall (= western bulwark)'', was a German defensive line built during the late 1930s. Started in 1936, opposite the French Maginot Line, it stretched more than from Kleve on the border with the Netherlands, along the western border of Nazi Germany, to the town of Weil am Rhein on the border with Switzerland. The line featured more than 18,000 bunkers, tunnels and tank traps. From September 1944 to March 1945, the Siegfried Line was subjected to a large-scale Allied offensive. Name The official German name for the defensive line construction program before and during the Second World War changed several times during the late 1930s. It came to be known as the "Westwall", but in English it was referred to as the "Siegfried Line" or, sometimes, the "West Wall". Various German names reflected different areas of construction: * Border Watch programme (pioneering programme) for the most advanced positions (1938) * Limes programme ...

Battle Of Saint-Malo
The Battle of Saint-Malo was fought between Allies of World War II, Allied and German forces for control of the French coastal town of Saint-Malo in Brittany during World War II. The battle was part of the Allied breakout across France and took place between 4 August and 2 September 1944. United States Army units, with the support of Free France, Free French and British forces, successfully assaulted the town and defeated its German defenders. The German garrison on a nearby island continued to resist until 2 September. Saint-Malo was one of the French towns designated as a fortress under the German Atlantic Wall program, and its prewar defenses had been expanded considerably before the Allied landings in Normandy during June 1944. As part of their invasion plans, the Allies intended to capture the town so that its port could be used to land supplies. While there was some debate over the necessity of this in August as the Allied forces broke out of Normandy and entered Brittany, ...

Counter-battery Fire
Counter-battery fire (sometimes called counter-fire) is a battlefield tactic employed to defeat the enemy's indirect fire elements ( multiple rocket launchers, artillery and mortars), including their target acquisition, as well as their command and control components. Counter-battery arrangements and responsibilities vary between nations but involve target acquisition, planning and control, and counter-fire. Counter-battery fire rose to prominence in World War I. Counter-battery radar detects incoming indirect fire and calculates its point of origin. That location data can be sent by a communications link to friendly forces, who can then fire on the enemy positions, hopefully before they can reposition (the "scoot" part of shoot-and-scoot tactics). Counter-RAM systems track incoming rocket, artillery, and mortar fire and attempt to intercept and destroy the projectiles or provide early warning to the target area. Background Indirect fire was introduced so that artillery co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
17 Cm Kanone 18
The 17 cm Kanone 18 in Mörserlafette (English: 17 cm Cannon 18 on Mortar Carriage), abbreviated as 17 cm K 18 in MrsLaf, was a German heavy gun used during World War II. Design The 17 cm K 18 in MrsLaf was a towed gun with a barrel 50 calibres long. The 17 cm K 18 in MrsLaf shared the same box trail carriage with the 21 cm Mörser 18. The carriage allowed transport of the weapon over short distances in one piece, whilst for longer distances the barrel was removed from the carriage and transported separately. A series of ramps and winches made removing the barrel a reasonably quick task for its time, but still required several hours. For all of the gun's bulk, a full 360-degree traverse could be achieved by two men. Dual-recoil mechanism A notable innovation by Krupp on the 21 cm Mörser 18 and the 17 cm Kanone 18 was the "double recoil" or dual-recoil carriage. The normal recoil forces were initially taken up by a conventional recoil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anzio Beachhead
The Battle of Anzio was a battle of the Italian Campaign of World War II that commenced January 22, 1944. The battle began with the Allied amphibious landing known as Operation Shingle, and ended on June 4, 1944, with the liberation of Rome. The operation was opposed by German and by Italian ''Repubblica Sociale Italiana'' (RSI) forces in the area of Anzio and Nettuno. Allied landings on the Italian mainland began in September 1943, and after slow gains against German resistance, the progress was stopped in December 1943 at the German defensive Gustav Line, south of Rome. The operation was initially commanded by Major General John P. Lucas, of the U.S. Army, commanding U.S. VI Corps with the intent to outflank German forces at the Winter Line and enable an attack on Rome. The success of an amphibious landing at that location, in a basin consisting substantially of reclaimed marshland and surrounded by mountains, depended on the element of surprise and the swiftness with whi ...

M10 Tank Destroyer
The M10 tank destroyer, formally known as 3-inch gun motor carriage M10 or M10 BBC, was an American tank destroyer of World War II. After US entry into World War II and the formation of the Tank Destroyer Force, a suitable vehicle was needed to equip the new battalions. By November 1941, the Army requested a vehicle with a gun in a fully rotating turret after other interim models were criticized for being too poorly designed. The prototype of the M10 was conceived in early 1942 and delivered in April that year. After appropriate changes to the hull and turret were made, the modified version was selected for production in June 1942 as the "3-inch Gun Motor Carriage M10". It mounted the 3-inch anti-aircraft gun M3, 3-inch (76.2 mm) gun M7 in a rotating turret on a modified M4 Sherman tank chassis. It was built in two variants. The M10 GMC used the M4A2 Sherman chassis and the M10A1 used the M4A3 chassis. Production of the two models ran from September 1942 to December 1943 and O ...

M3 Lee
The M3 Lee, officially Medium Tank, M3, was an American medium tank used during World War II. The turret was produced in two different forms, one for US needs and one modified to British requirements to place the radio next to the commander. In British Commonwealth service, the tank was called by two names: tanks employing US-pattern turrets were called "Lee", named after Confederate general Robert E. Lee, while those with British-pattern turrets were known as "Grant", named after Union general Ulysses S. Grant. Design commenced in July 1940, and the first M3s were operational in late 1941. The US Army needed a medium tank armed with a 75 mm gun and coupled with the United Kingdom's immediate demand for 3,650 medium tanks, the Lee began production by late 1940. The design was a compromise meant to produce a tank as soon as possible and serve only until replaced by the following M4 Sherman tank. The M3 was reliable, had considerable firepower, good armor, and high mobility b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Normandy Landings
The Normandy landings were the landing operations and associated airborne operations on 6 June 1944 of the Allies of World War II, Allied invasion of Normandy in Operation Overlord during the Second World War. Codenamed Operation Neptune and often referred to as D-Day (after D-Day (military term), the military term), it is the largest seaborne invasion in history. The operation began the liberation of France, and the rest of Western Europe, and laid the foundations of the Allied victory on the Western Front (World War II), Western Front. Planning for the operation began in 1943. In the months leading up to the invasion, the Allies conducted a substantial military deception, codenamed Operation Bodyguard, to mislead the Germans as to the date and location of the main Allied landings. The weather on the day selected for D-Day was not ideal, and the operation had to be delayed 24 hours; a further postponement would have meant a delay of at least two weeks, as the planners had re ...
