Fort Greble
Fort Greble was an American Civil War-era Union fortification constructed as part of the defenses of Washington, D.C. during that war. Named for First Lieutenant John Trout Greble, the first West Point graduate killed in the U.S. Civil War, it protected the junction of the Anacostia and Potomac rivers, and from its position on a bluff in the Congress Heights, precluded any bombardment of the Washington Navy Yard and southeastern portions of the city. It was supported by Fort Carroll to the northeast and Fort Foote to the south. It never fired a shot during the war, and after a brief stint as a U.S. Army Signal Corps training facility, was abandoned and the land returned to its natural state. As of July 2007, the site of the fort is a community park. Planning and construction Prior to the outbreak of war, Congress Heights (so called because the Capitol building in downtown Washington could be seen from the tops of the hills) were owned by the Berry family, who also owned much of ...

John Trout Greble
John Trout Greble (January 19, 1834 in Philadelphia – June 10, 1861 in Virginia) was a soldier in the United States Army and the Union army in the American Civil War. He was killed at the battle of Big Bethel, and was the first graduate of the United States Military Academy to be killed in the war. Biography He graduated from the U. S. Military Academy in 1854, was assigned to the 2nd artillery, and stationed at Newport, Rhode Island. In September 1854 he was made 2nd lieutenant and sent to Tampa, Florida, where he served in the Indian troubles for two years. He was compelled, in consequence of a severe fever, to return home on sick leave, but in the beginning of 1856 resumed his duties, acting part of the time as quartermaster and commissary until December 1856, when he was appointed acting assistant professor of geography, history, and ethics in the U.S. Military Academy, where he remained until September 24, 1860. He was promoted to 1st lieutenant on March 3, 1857. He was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort Wagner
Fort Wagner or Battery Wagner was a beachhead fortification on Morris Island, South Carolina, that covered the southern approach to Charleston Harbor. It was the site of two American Civil War battles in the campaign known as Operations Against the Defenses of Charleston in 1863, in which United States forces took heavy casualties while trying to seize the fort. Construction Named for deceased Lt. Col. Thomas M. Wagner, Fort Wagner measured by , and spanned an area between the Atlantic on the east and an impassable swamp on the west. Its walls, composed of sand and earth, rose above the level beach and were supported by palmetto logs and sandbags. The fort's arsenal included fourteen cannons, the largest a Columbiad that fired a 128-pound shell. It was a large structure capable of sheltering nearly 1,000 of the fort's 1,700-man garrison and provided substantial protection against naval shelling. The fort's land face was protected by a water-filled trench, wide and dee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parrott Rifle
The Parrott rifle was a type of muzzle-loading rifled artillery weapon used extensively in the American Civil War. Parrott rifle The gun was invented by Captain Robert Parker Parrott, a West Point graduate. He was an American soldier and inventor of military ordnance. He resigned from the service in 1836 and became the superintendent of the West Point Foundry in Cold Spring, New York. He created the first Parrott rifle (and corresponding projectile) in 1860 and patented it in 1861.Pritchard Jr, Russ A.Civil War Weapons and Equipment, p.82. Globe Pequit Press, 2003. . Daniel Treadwell, who developed a method for making built-up guns in early 1840s, tried to claim that his patent infringed on an earlier one, but in 1866 S.D.N.Y. court dismissed it, deciding that Treadwell's claim was invalidated by a 1843 British patent to John Frith. Parrotts were manufactured with a combination of cast and wrought iron. The cast iron made for an accurate gun, but was brittle enough to suffer ...

Mortar (weapon)
A mortar is usually a simple, lightweight, man-portable, muzzle-loaded weapon, consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. They launch explosive shells (technically called bombs) in high-arcing ballistic trajectories. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. History Mortars have been used for hundreds of years. The earliest mortars were used in Korea in a 1413 naval battle when Korean gunsmiths developed the ''wan'gu'' (gourd-shaped mortar) (완구, 碗口). The earliest version of the ''wan'gu'' dates back to 1407. Choi Hae-san (최해산, 崔海山) (1380–1443), the son of Choe Mu-seon (최무선, 崔茂宣) (1325–1395), is generally credited with inventing the ''wan'gu''. In the Ming dynasty, general Qi Jiguang recorded the use of a mini cannon called the Hu dun pao that was simi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbette
Barbettes are several types of gun emplacement in terrestrial fortifications or on naval ships. In recent naval usage, a barbette is a protective circular armour support for a heavy gun turret. This evolved from earlier forms of gun protection that eventually led to the pre-dreadnought. The name ''barbette'' ultimately comes from fortification - it originally meant a raised platform or mound, as in the French phrase ''en barbette'', which refers to the practice of firing a cannon over a parapet rather than through an embrasure in a fortification's casemate. The former gives better angles of fire but less protection than the latter. The disappearing gun was a variation on the barbette gun; it consisted of a heavy gun on a carriage that would retract behind a parapet or into a gunpit for reloading. Barbettes were primarily used in coastal defences, but saw some use in a handful of warships, and some inland fortifications. The term is also used for certain aircraft gun mounts. Sh ...

Howitzer
A howitzer () is a long- ranged weapon, falling between a cannon (also known as an artillery gun in the United States), which fires shells at flat trajectories, and a mortar, which fires at high angles of ascent and descent. Howitzers, like other artillery equipment, are usually organized in a group called a battery. Howitzers, together with long-barreled guns, mortars, and rocket artillery, are the four basic types of modern artillery. Mortars fire at angles of elevation greater than 45°, and are useful for mountain warfare because the projectile could go over obstacles. Cannons fire at low angles of elevation (<45°), and the projectile lands much faster at its target than it would in the case of a mortar. But the cannon is not useful if there is an obstacle like a hill/wall in front of its target. Etymology The English word ''howitzer'' comes from the Czech word , from , 'crowd', and is in turn a borrowing from the Middle High German word or (mode ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Albion P
Albion is an alternative name for Great Britain. The oldest attestation of the toponym comes from the Greek language. It is sometimes used poetically and generally to refer to the island, but is less common than 'Britain' today. The name for Scotland in most of the Celtic languages is related to Albion: ''Alba'' in Scottish Gaelic, ''Albain'' (genitive ''Alban'') in Irish language, Irish, ''Nalbin'' in Manx language, Manx and ''Alban'' in Welsh language, Welsh and Cornish language, Cornish. These names were later Latinisation of names, Latinised as ''Albania'' and Anglicisation, Anglicised as ''Albany'', which were once alternative names for Scotland. ''New Albion'' and ''Albionoria'' ("Albion of the North") were briefly suggested as name of Canada, names of Canada during the period of the Canadian Confederation. Sir Francis Drake gave the name New Albion to what is now California when he landed there in 1579. Etymology The toponym is thought to derive from the Greek word , L ...

Malaria
Malaria is a mosquito-borne infectious disease that affects humans and other animals. Malaria causes symptoms that typically include fever, tiredness, vomiting, and headaches. In severe cases, it can cause jaundice, seizures, coma, or death. Symptoms usually begin ten to fifteen days after being bitten by an infected mosquito. If not properly treated, people may have recurrences of the disease months later. In those who have recently survived an infection, reinfection usually causes milder symptoms. This partial resistance disappears over months to years if the person has no continuing exposure to malaria. Malaria is caused by single-celled microorganisms of the ''Plasmodium'' group. It is spread exclusively through bites of infected ''Anopheles'' mosquitoes. The mosquito bite introduces the parasites from the mosquito's saliva into a person's blood. The parasites travel to the liver where they mature and reproduce. Five species of ''Plasmodium'' can infect and be spread by h ...

Mosquitoes
Mosquitoes (or mosquitos) are members of a group of almost 3,600 species of small flies within the family Culicidae (from the Latin ''culex'' meaning "gnat"). The word "mosquito" (formed by ''mosca'' and diminutive ''-ito'') is Spanish for "little fly". Mosquitoes have a slender segmented body, one pair of wings, one pair of halteres, three pairs of long hair-like legs, and elongated mouthparts. The mosquito life cycle consists of egg, larva, pupa, and adult stages. Eggs are laid on the water surface; they hatch into motile larvae that feed on aquatic algae and organic material. These larvae are important food sources for many freshwater animals, such as dragonfly nymphs, many fish, and some birds such as ducks. The adult females of most species have tube-like mouthparts (called a proboscis) that can pierce the skin of a host and feed on blood, which contains protein and iron needed to produce eggs. Thousands of mosquito species feed on the blood of various hosts — v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
