Sinking Of USS Housatonic
The Sinking of USS ''Housatonic'' on 17 February 1864 during the American Civil War was an important turning point in naval warfare. The Confederate States Navy submarine, made her first and only attack on a Union Navy warship when she staged a clandestine night attack on in Charleston harbor. ''H.L. Hunley'' approached just under the surface, avoiding detection until the last moments, then embedded and remotely detonated a spar torpedo that rapidly sank the sloop-of-war with the loss of five Union sailors. ''H.L. Hunley'' became renowned as the first submarine to successfully sink an enemy vessel in combat, and was the direct progenitor of what would eventually become international submarine warfare, although the victory was Pyrrhic and short-lived, since the submarine did not survive the attack and was lost with all eight Confederate crewmen. Sinking On the evening of 17 February 1864, made her first mission against an enemy vessel during the American Civil War. Armed w ...

American Civil War
The American Civil War (April 12, 1861May 26, 1865; also known by Names of the American Civil War, other names) was a civil war in the United States between the Union (American Civil War), Union ("the North") and the Confederate States of America, Confederacy ("the South"), which was formed in 1861 by U.S. state, states that had Secession in the United States, seceded from the Union. The Origins of the American Civil War, central conflict leading to war was a dispute over whether Slavery in the United States, slavery should be permitted to expand into the western territories, leading to more slave states, or be prohibited from doing so, which many believed would place slavery on a course of ultimate extinction. Timeline of events leading to the American Civil War, Decades of controversy over slavery came to a head when Abraham Lincoln, who opposed slavery's expansion, won the 1860 presidential election. Seven Southern slave states responded to Lincoln's victory by seceding f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine Warfare
Submarine warfare is one of the four divisions of underwater warfare, the others being anti-submarine warfare, Naval mine, mine warfare and Naval mine, mine countermeasures. Submarine warfare consists primarily of Diesel engine, diesel and nuclear submarines using torpedoes, missiles or nuclear weapons, as well as advanced sensing equipment, to attack other submarines, ships, or land targets. Submarines may also be used for reconnaissance and landing of special forces as well as deterrence. In some navies they may be used for task force screening. The effectiveness of submarine warfare partly depends on the anti-submarine warfare carried out in response. American Revolution The first attack by a submarine occurred on September 8, 1776, by the American submarine ''Turtle (submersible), Turtle'' in an unsuccessful attack on the British warship ''Eagle.'' American Civil War The age of submarine warfare began during the American Civil War. The 1860s was a time of many turning ...

Blast Injury
A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. Blast injuries occur with the detonation of high-order explosives as well as the deflagration of low order explosives. These injuries are compounded when the explosion occurs in a confined space. Classification Blast injuries are divided into four classes: primary, secondary, tertiary, and quaternary. Primary injuries Primary injuries are caused by blast overpressure waves, or shock waves. Total body disruption is the most severe and invariably fatal primary injury. Primary injuries are especially likely when a person is close to an exploding munition, such as a land mine. The ears are most often affected by the overpressure, followed by the lungs and the hollow organs of the gastrointestinal tract. Gastrointestinal injuries may present after a delay of hours or even days. Injury from blast overpressure is a pressure and time dependent function. By increasing the p ...

Concretion
A concretion is a hard and compact mass formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary rock or soil. Concretions are often ovoid or spherical in shape, although irregular shapes also occur. The word ''concretion'' is borrowed from Latin , itself derived from ''concrescere'' , from ''con-'' and ''crescere'' . Concretions form within layers of sedimentary strata that have already been deposited. They usually form early in the burial history of the sediment, before the rest of the sediment is hardened into rock. This concretionary cement often makes the concretion harder and more resistant to weathering than the host stratum. There is an important distinction to draw between concretions and nodules. Concretions are formed from mineral precipitation around some kind of nucleus while a nodule is a replacement body. Descriptions dating from the 18th century attest to the fact that concretions have long been regarde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Hunley
''The Hunley'' is a 1999 American historical drama television film written and directed by John Gray, from a story by Gray and John Fasano. The film stars Armand Assante, Donald Sutherland, Alex Jennings, Michael Dolan, and Christopher Bauer, and is based on the true story of the '' H. L. Hunley'' submarine and the action of 17 February 1864. It aired on TNT on July 11, 1999. Plot Horace L. Hunley takes his ship, the '' H.L. Hunley'', out in the Charleston, South Carolina harbor and it sinks with all hands. As the blockade still needs to be broken, General P. G. T. Beauregard has the ship raised and puts George E. Dixon in charge. He starts looking for a crew and after some difficulty finally finds enough volunteers to man it. They practice cranking the propeller. The crew do not all get along with each other. Dixon flashes back to the Battle of Shiloh, where a gold coin given to him by his wife (who was later killed in a steamboat explosion caused by a drifting mine) de ...

Fort Moultrie
Fort Moultrie is a series of fortifications on Sullivan's Island, South Carolina, built to protect the city of Charleston, South Carolina, Charleston, South Carolina. The first fort, formerly named Fort Sullivan, built of Cabbage Palmetto, palmetto logs, inspired the Flag of South Carolina, flag and nickname of South Carolina, as "The Palmetto State". The fort was renamed for the U.S. patriot commander in the Battle of Sullivan's Island, General William Moultrie. During British occupation, in 1780–1782, the fort was known as Fort Arbuthnot. History American Revolution Col. Moultrie took command of Sullivan's Island on March 2, 1776, which included a garrison of 413 men of the 2nd South Carolina Regiment of Infantry and 22 men of the 4th South Carolina Regiment, artillery. The island included a fort, still under construction at the southern tip, which was being supervised by Capt. De Brahm. The square design, with corner bastions, was supposed to have parallel row ...

Lifeboat (rescue)
A rescue lifeboat is a boat rescue craft which is used to attend a vessel in distress, or its survivors, to rescue crew and passengers. It can be hand pulled, sail powered or powered by an engine. Lifeboats may be rigid, Inflatable boat, inflatable or rigid-inflatable combination-hulled vessels. Overview There are generally three types of boat, in-land (used on lakes and rivers), in-shore (used closer to shore) and off-shore (into deeper waters and further out to sea). A rescue lifeboat is a boat designed with specialised features for searching for, rescuing and saving the lives of people in peril at sea or other large bodies of water. In the United Kingdom and Ireland rescue lifeboats are typically vessels crewed by volunteers, intended for quick dispatch, launch and transit to reach a ship or individuals in trouble at sea. Off-shore boats are referred to as 'All-weather' and generally have a range of 150–250 nautical miles. Characteristics such as capability to withstand he ...

Hull (watercraft)
A hull is the watertight body of a ship, boat, submarine, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or Mast (sailing), mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box, in the case of scow barges, to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bot ...

Cannon
A cannon is a large-caliber gun classified as a type of artillery, which usually launches a projectile using explosive chemical propellant. Gunpowder ("black powder") was the primary propellant before the invention of smokeless powder during the late 19th century. Cannons vary in gauge (firearms), gauge, effective range, mobility (military), mobility, rate of fire, elevation (ballistics), angle of fire and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. A cannon is a type of heavy artillery weapon. The word ''cannon'' is derived from several languages, in which the original definition can usually be translated as ''tube'', ''cane'', or ''reed''. The earliest known depiction of cannons may have appeared in Science and technology of the Song dynasty#Gunpowder warfare, Song dynasty China as early as the 12th century; however, solid archaeological and documentary evidence of cannons do ...
