No. 1 Grenade
The Grenade, Hand, No. 1 was the first British hand grenade used in World War I. It was designed in the Royal Laboratory, based on reports and samples of Japanese hand grenades during the Russo-Japanese War provided by General Sir Aylmer Haldane, who was a British observer of that war. The grenade proper is a container of explosive material with an iron fragmentation band. The fuse was of the impact sort, detonating when the top of the grenade hit the ground. A long cane handle (approximately 16 inches or 40 cm) allowed the user to throw the grenade further than the blast of the explosion. To ensure that the grenade hit the ground nose first, a cloth streamer was attached to the end of the handle. When thrown, this unfurled and acted as a tail to stabilize flight. The grenade came with a metal loop so it could hang from a belt. In the trenches When the battlefield became confined to the trenches, the long handle became a liability, causing several accidents.

Hand Grenade
A grenade is an explosive weapon typically thrown by hand (also called hand grenade), but can also refer to a shell (explosive projectile) shot from the muzzle of a rifle (as a rifle grenade) or a grenade launcher. A modern hand grenade generally consists of an explosive charge ("filler"), a detonator mechanism, an internal striker to trigger the detonator, and a safety lever secured by a cotter pin. The user removes the safety pin before throwing, and once the grenade leaves the hand the safety lever gets released, allowing the striker to trigger a primer that ignites a fuze (sometimes called the delay element), which burns down to the detonator and explodes the main charge. Grenades work by dispersing fragments (fragmentation grenades), shockwaves (high-explosive, anti-tank and stun grenades), chemical aerosols (smoke and gas grenades) or fire ( incendiary grenades). Fragmentation grenades ("frags") are probably the most common in modern armies, and when the word ''gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuse (explosives)
In an explosive, pyrotechnics, pyrotechnic device, or military munition, a fuse (or fuze) is the part of the device that initiates function. In common usage, the word fuse is used indiscriminately. However, when being specific (and in particular in a military context), the term ''fuse'' describes a simple pyrotechnic initiating device, like the cord on a firecracker whereas the term ''fuze'' is used when referring to a more sophisticated ignition device incorporating mechanical and/or electronics, electronic components, such as a proximity fuze for an M107 projectile, M107 artillery shell, magnetometer, magnetic or acoustic signature, acoustic fuze on a sea mine, spring-loaded grenade fuze, pencil detonator, or anti-handling device. History Documented evidence suggests that the earliest fuses were first used by the Song Chinese between the 10th and 12th centuries. After the Chinese invented gunpowder, they began adapting its explosive properties for use in military technology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I Grenades Of The United Kingdom
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mills Bomb
"Mills bomb" is the popular name for a series of British hand grenades which were designed by William Mills. They were the first modern fragmentation grenades used by the British Army and saw widespread use in the First and Second World Wars. Development William Mills, a hand grenade designer from Sunderland, patented, developed and manufactured the "Mills bomb" at the Mills Munitions Factory in Birmingham, England, in 1915. The Mills bomb was inspired by an earlier design by Belgian captain Leon Roland, who later engaged in a patent lawsuit. Col. Arthur Morrow, a New Zealand Wars officer, also believed aspects of his patent were incorporated into the Mills Bomb. The Mills bomb was adopted by the British Army as its standard hand grenade in 1915 as the No. 5. The Mills bomb underwent numerous modifications. The No. 23 was a No. 5 with a rodded base plug which allowed it to be fired from a rifle. This concept evolved further with the No. 36, a variant with a detachable base ...

Jam Tin Grenade
The double cylinder, Nos. 8 and No. 9 hand grenades, also known as the "jam tins", are a type of improvised explosive device used by the British and Commonwealth forces, notably the Australian and New Zealand Army Corps (ANZAC) in World War I. The jam tin, or bully beef tin, was one of many grenades designed by ANZACs in the early part of the First World War in response to a lack of equipment suited to trench warfare. The grenade was an inner can of explosive with an outer can of metal fragments or ball bearings. The heavier pattern No. 9 grenade contained more high explosive and more metal fragments. The fuse was ignited by a friction device or a cigarette. Initially when demand for grenades was at its greatest, engineers were encouraged to improvise their own grenades from the tins containing the soldier's ration of jam, hence the name. Incidents with the improvised form and the supply of superior grenades led to official withdrawal of the design. Jam tin grenades were used as ...

British Expeditionary Force (World War I)
The British Expeditionary Force (BEF) was the six-divisions the British Army sent to the Western Front during the First World War. Planning for a British Expeditionary Force began with the 1906–1912 Haldane reforms of the British Army carried out by the Secretary of State for War Richard Haldane following the Second Boer War (1899–1902). The term ''British Expeditionary Force'' is often used to refer only to the forces present in France prior to the end of the First Battle of Ypres on 22 November 1914. By the end of 1914—after the battles of Mons, Le Cateau, the Aisne and Ypres—the existent BEF had been almost exhausted, although it helped stop the German advance.Chandler (2003), p. 211 An alternative endpoint of the BEF was 26 December 1914, when it was divided into the First and Second Armies (a Third, Fourth and Fifth being created later in the war). "British Expeditionary Force" remained the official name of the British armies in France and Flanders thro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ypres
Ypres ( , ; nl, Ieper ; vls, Yper; german: Ypern ) is a Belgian city and municipality in the province of West Flanders. Though the Dutch name is the official one, the city's French name is most commonly used in English. The municipality comprises the city of Ypres/Ieper and the villages of Boezinge, Brielen, Dikkebus, Elverdinge, Hollebeke, Sint-Jan, Vlamertinge, Voormezele, Zillebeke, and Zuidschote. Together, they are home to about 34,900 inhabitants. During the First World War, Ypres (or "Wipers" as it was commonly known by the British troops) was the centre of the Battles of Ypres between German and Allied forces. History Origins before First World War Ypres is an ancient town, known to have been raided by the Romans in the first century BC. It is first mentioned by name in 1066 and is probably named after the river Ieperlee on the banks of which it was founded. During the Middle Ages, Ypres was a prosperous Flemish city with a population of 40,000 in 1200 AD, renow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trench Warfare
Trench warfare is a type of land warfare using occupied lines largely comprising military trenches, in which troops are well-protected from the enemy's small arms fire and are substantially sheltered from artillery. Trench warfare became archetypically associated with World War I (1914–1918), when the Race to the Sea rapidly expanded trench use on the Western Front starting in September 1914.. Trench warfare proliferated when a revolution in firepower was not matched by similar advances in mobility, resulting in a grueling form of warfare in which the defender held the advantage. On the Western Front in 1914–1918, both sides constructed elaborate trench, underground, and dugout systems opposing each other along a front, protected from assault by barbed wire. The area between opposing trench lines (known as " no man's land") was fully exposed to artillery fire from both sides. Attacks, even if successful, often sustained severe casualties. The development of armoured ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fragmentation (weaponry)
Fragmentation is the process by which the casing, shot, or other components of an anti-personnel weapon, bomb, barrel bomb, land mine, IED, artillery, mortar, tank gun, or autocannon shell, rocket, missile, grenade, etc. are dispersed and/or shattered by the detonation of the explosive filler. The correct term for these pieces is "fragmentation"; "shards" or "splinters" can be used for non-preformed fragments. Preformed fragments can be of various shapes (spheres, cubes, rods, etc.) and sizes, and are normally held rigidly within some form of matrix or body until the high explosive (HE) filling is detonated. The resulting high-velocity fragments produced by either method are the main lethal mechanisms of these weapons, rather than the heat or overpressure caused by detonation, although offensive grenades are often constructed without a frag matrix. These casing pieces are often incorrectly referred to as "shrapnel", particularly by non-military media sources. History The ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Explosive Material
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
