RAF Hereford
RAF Credenhill, also known as RAF Hereford, was a non-flying station of the Royal Air Force situated in the village of Credenhill near Hereford, United Kingdom. It was commissioned in 1940 and served as home for a range of training schools from 1940 until closure in 1994. The site was subsequently obtained by the British Army. History First World War After the outbreak of the First World War, the Ministry of Munitions were required to create a number of Royal Ordnance Factory munitions production facilities quickly and cheaply. In 1912 Herefordshire County Council had bought of the former Rotherwas estate from the Lubienski-Bodenham family, overlooked by Dinedor Hill and bordered by the Wye meadows. A site of was acquired by the Ministry on 15 June 1916, at Lower Bullingham just south of Hereford on the junction of the Welsh Marches Line and the Hereford, Ross and Gloucester Railway. Laid out to a standard design, ROF Rotherwas encompassed: * standard-gauge railway * of r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Credenhill
Credenhill is a village and civil parish in Herefordshire, England. The population of this civil parish taken at the 2011 Census was 2,271. Near Credenhill is the site of the former Royal Air Force station, RAF Credenhill. It was redeveloped by the British Army for new headquarters for the 22 Special Air Service Regiment, who moved in 1999. The following year, the base was designated as Stirling Lines. History Credenhill village has had military connections since 80 BC, when Iron Age Celts constructed a hill fort and earthwork defence system commanding the surrounding area. The Romans founded the town of Magnis at what is now Kenchester, which was later abandoned during the withdrawal of Roman armies from Britain. In 428 AD Magnis was destroyed by a fire during raids by the Picts and Scots. The remains of the old fort was occupied by the Saxons in 480 AD. The Saxon chief Creoda occupied the fort in 540 AD, and "Creoda's Hill" gave its name to Credenhill. During the Fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hereford, Ross And Gloucester Railway
The Hereford, Ross and Gloucester Railway (also known as the Gloucester and Dean Forest Railway), was a railway which ran for linking Hereford and Gloucester, England, via Ross-on-Wye. It was opened on 1 June 1855 as a broad gauge line, it was amalgamated with the Great Western Railway in 1862. In 1869 the railway was converted to standard gauge. The railway was closed to passengers on 2 November 1964, freight services between Ross-on-Wye railway station and Grange Court railway station continued on until 1 November 1965. History Opening On 1 June 1851 Parliament of the United Kingdom, Parliament passed an act allowing the railway's construction and although construction was delayed by bad weather in January 1853 the line was tested out by locomotives on 31 May 1855; the next day the railway was officially opened, 1 June 1855.

Special Air Service
The Special Air Service (SAS) is a special forces unit of the British Army. It was founded as a regiment in 1941 by David Stirling and in 1950, it was reconstituted as a corps. The unit specialises in a number of roles including counter-terrorism, hostage rescue, direct action and covert reconnaissance. Much of the information about the SAS is highly classified, and the unit is not commented on by either the British government or the Ministry of Defence due to the secrecy and sensitivity of its operations. The corps currently consists of the 22 Special Air Service Regiment, the regular component, as well as the 21 Special Air Service Regiment (Artists) (Reserve) and the 23 Special Air Service Regiment (Reserve), which are reserve units, all under the operational command of United Kingdom Special Forces (UKSF). Its sister unit is the Royal Navy's Special Boat Service which specialises in maritime counter-terrorism. Both units are under the operational control of the Directo ...

RAF Hereford - 330 Entry Admin Apprentices Graduation Photograph - August 1973
The Royal Air Force (RAF) is the United Kingdom's air and space force. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by regrouping the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security".

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mustard Gas
Mustard gas or sulfur mustard is a chemical compound belonging to a family of cytotoxic and blister agents known as mustard agents. The name ''mustard gas'' is technically incorrect: the substance, when dispersed, is often not actually a gas, but is instead in the form of a fine mist of liquid droplets.https://www.acs.org/content/dam/acsorg/education/resources/highschool/chemmatters/gc-mustard-gas-personal-safety-and-natl-security.pdf Mustard gases form blisters on exposed skin and in the lungs, often resulting in prolonged illness ending in death. The active ingredient in typical mustard gas is the organosulfur compound bis(2-chloroethyl) sulfide. In the wider sense, compounds with the structural element are known as ''sulfur mustards'' and ''nitrogen mustards'', respectively. Such compounds are potent alkylating agents, which can interfere with several biological processes.

Avonmouth Docks
The Avonmouth Docks are part of the Port of Bristol, in England. They are situated on the northern side of the mouth of the River Avon, opposite the Royal Portbury Dock on the southern side, where the river joins the Severn estuary, within Avonmouth. Accessible via a long and wide lock, today the docks are one of the UK's major ports for chilled foods, especially fruit and vegetables. Land-side freight access and distribution is via either the M5 motorway or the Henbury Loop Line, whilst rail-passenger access is via Avonmouth railway station on the Severn Beach Line. Background Bristol Harbour had always been a major centre of trade within the wider UK economy, due to its strategic location to the west of the country, allowing access to both the Atlantic Ocean and the Mediterranean. Coastal trade was also important, with the area called "Welsh Back" concentrating on trows with cargoes from the Slate industry in Wales, stone, timber and coal. However, by the 18th century the ...

National Smelting Company
The National Smelting Company was a nationalised zinc smelting company in Avonmouth, England. It was established by Minister of Munitions Winston Churchill to produce mustard gas during World War I. After World War I, it was bought by private business interests. From 1929 it became part of Australia's Imperial Smelting Corporation. The site – also known as the Britannia smelting works – was where the Imperial Smelting Process was developed. From 1967, the Avonmouth Works was home to the largest and most efficient zinc blast furnace in the world. The site remained operational until 2003 when the production of zinc, cadmium, lead and sulphuric acid ceased. The site is being redeveloped as a supermarket distribution centre for Asda and a recycling plant for SITA UK. Background During the later part of World War I, it was proposed to make Avonmouth Docks the UK centre of production of dichloroethyl sulphide, also known as mustard gas. However, its production was against the H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amatol
Amatol is a highly explosive material made from a mixture of TNT and ammonium nitrate. The British name originates from the words ammonium and toluene (the precursor of TNT). Similar mixtures (one part dinitronaphthalene and seven parts ammonium nitrate) were known as Schneiderite in France. Amatol was used extensively during World War I and World War II, typically as an explosive in military weapons such as aircraft bombs, shells, depth charges, and naval mines.Brown, G. I. (1998). ''The Big Bang: A History of Explosives''. Sutton Publishing . pp. 158-163. It was eventually replaced with alternative explosives such as Composition B, Torpex, and Tritonal. Invention Following the Shell Crisis of 1915 in which the UK did not have enough ordnance due to a lack of explosives, a team at the Royal Arsenal laboratories produced a mixture of ammonium nitrate and TNT, known as Amatol for short. Special factories were constructed for the manufacture of ammonium nitrate by the double dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lyddite
Picric acid is an organic compound with the formula (O2N)3C6H2OH. Its IUPAC name is 2,4,6-trinitrophenol (TNP). The name "picric" comes from el, πικρός (''pikros''), meaning "bitter", due to its bitter taste. It is one of the most acidic phenols. Like other strongly nitrated organic compounds, picric acid is an explosive, which is its primary use. It has also been used as medicine (antiseptic, burn treatments) and as a dye. History Picric acid was probably first mentioned in the alchemical writings of Johann Rudolf Glauber. Initially, it was made by nitrating substances such as animal horn, silk, indigo, and natural resin, the synthesis from indigo first being performed by Peter Woulfe during 1771. The German chemist Justus von Liebig had named picric acid (rendered in French as ). Picric acid was given that name by the French chemist Jean-Baptiste Dumas in 1841. Its synthesis from phenol, and the correct determination of its formula, were accomplished during 1841 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard-gauge Railway
A standard-gauge railway is a railway with a track gauge of . The standard gauge is also called Stephenson gauge (after George Stephenson), International gauge, UIC gauge, uniform gauge, normal gauge and European gauge in Europe, and SGR in East Africa. It is the most widely used track gauge around the world, with approximately 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia, Finland, and Uzbekistan. The distance between the inside edges of the rails is defined to be 1435 mm except in the United States and on some heritage British lines, where it is defined in U.S. customary/Imperial units as exactly "four feet eight and one half inches" which is equivalent to 1435.1mm. History As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge met – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
