Time Bomb
A time bomb (or a timebomb, time-bomb) is a bomb whose detonation is triggered by a timer. The use (or attempted use) of time bombs has been for various purposes including insurance fraud, terrorism, assassination, sabotage and warfare. They are a popular feature in fictional thriller and action films as they offer a way of imparting a dramatic sense of urgency. Construction The explosive charge is the main component of any bomb, and makes up most of the size and weight of it. It is the damaging element of the bomb (along with any fragments or shrapnel the explosion might produce with its container or neighboring objects). The explosive charge is detonated by a detonator. A time bomb's timing mechanism may be professionally manufactured either separately or as part of the device, or it may be improvised from an ordinary household timer such as a wind-up alarm clock, wrist watch, digital kitchen timer, or notebook computer. The timer can be programmed to count up or count down ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrist Watch
A watch is a portable timepiece intended to be carried or worn by a person. It is designed to keep a consistent movement despite the motions caused by the person's activities. A wristwatch is designed to be worn around the wrist, attached by a watch strap or other type of bracelet, including metal bands, leather straps or any other kind of bracelet. A pocket watch is designed for a person to carry in a pocket, often attached to a chain. Watches were developed in the 17th century from spring-powered clocks, which appeared as early as the 14th century. During most of its history the watch was a mechanical device, driven by clockwork, powered by winding a mainspring, and keeping time with an oscillating balance wheel. These are called ''mechanical watches''. In the 1960s the electronic ''quartz watch'' was invented, which was powered by a battery and kept time with a vibrating quartz crystal. By the 1980s the quartz watch had taken over most of the market from the mechani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bremerhaven
Bremerhaven (, , Low German: ''Bremerhoben'') is a city at the seaport of the Free Hanseatic City of Bremen, a state of the Federal Republic of Germany. It forms a semi-enclave in the state of Lower Saxony and is located at the mouth of the River Weser on its eastern bank, opposite the town of Nordenham. Though a relatively new city, it has a long history as a trade port and today is one of the most important German ports, playing a role in Germany's trade.

Confederate Secret Service
The Confederate Secret Service refers to any of a number of official and semi-official secret service organizations and operations conducted by the Confederate States of America during the American Civil War. Some of the organizations were under the direction of the Confederate government, others operated independently with government approval, while still others were either completely independent of the government or operated with only its tacit acknowledgment. By 1864, the Confederate government was attempting to gain control over the various operations that had sprung up since the beginning of the war, but often with little success. Secret legislation was put before the Confederate Congress to create an official Special and Secret Bureau of the War Department. The legislation was not enacted until March 1865 and was never implemented; however, a number of groups and operations have historically been referred to as having been part of the Confederate Secret Service. In April 186 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
City Point, Virginia
City Point was a town in Prince George County, Virginia, that was annexed by the independent city of Hopewell in 1923. It served as headquarters of the Union Army during the siege of Petersburg during the American Civil War. History 1613-1863 City Point owed its existence to its site overlooking the James and Appomattox Rivers. City Point was established in 1613 by Sir Thomas Dale. It was first known as Bermuda Cittie, but soon was renamed "Charles City" and was located in Charles City Shire when it was formed in 1634. Charles City Shire soon became known as Charles City County in 1637. City Point was included in the portion subdivided in 1703 to form Prince George County. In 1619 Samuel Sharpe and Samuel Jordan from City Point (then named Charles City) were burgesses at the first meeting of the House of Burgesses. City Point was unaffected by the American Revolution until the final year of the war in January 1781. At that time the British fleet, commanded by Benedict ...

Isaac Doolittle
Isaac Doolittle (August 3, 1721 – February 13, 1800) was an early American clockmaker, inventor, engineer, manufacturer, militia officer, entrepreneur, printer, politician, and brass, iron, and silver artisan. Doolittle was a watchmaker and clockmaker, known for making and selling at his shop in New Haven, Connecticut one of the first brass wheel hall clocks in America, where he also crafted and sold scientific instruments, and is regarded as "the first native practitioner" of silversmithing in the Connecticut Colony. He was also an engraver and printer of both legal forms and currency, and became the first American to design, manufacture, and sell a printing press in 1769. Somewhat late in life, he became a successful self-educated bell-foundryman, learning the difficult craft of casting large metal bells. Doolittle was an important figure in the religious life of Connecticut as an Episcopal Churchwarden and co-founder of Trinity Church on the Green in New Haven. Cal ...

David Bushnell
David Bushnell (August 30, 1740 – 1824 or 1826), of Westbrook, Connecticut, was an American inventor, a patriot, one of the first American combat engineers, a teacher, and a medical doctor. Bushnell invented the first submarine to be used in battle, as well as a floating mine triggered by contact. He was a veteran of the Revolutionary War. Early life David Bushnell was born in a secluded part of Saybrook, Connecticut on the 30th August, 1740 and baptized in 1743 into a farming family in what is now Westbrook, Connecticut where his parents Nehemiah Bushnell (1710 – d. bef 1762) and Sarah (Susan) Ingham Bushnell owned a farm. He was the first of five children born. Following the death of his father circa 1769, he sold his half interest in the family Westbrook farm to his brother Ezra and entered Yale College in 1771 at the relatively old age of 31. The ''Turtle'' submarine Bushnell is credited with creating the first submarine ever used in combat, while studying at Yale ...

New York Harbor
New York Harbor is at the mouth of the Hudson River where it empties into New York Bay near the East River tidal estuary, and then into the Atlantic Ocean on the east coast of the United States. It is one of the largest natural harbors in the world, and is frequently named the best natural harbor in the world. It is also known as Upper New York Bay, which is enclosed by the New York City boroughs of Manhattan, Brooklyn, and Staten Island and the Hudson County, New Jersey municipalities of Jersey City and Bayonne. The name may also refer to the entirety of New York Bay including Lower New York Bay. Although the United States Board on Geographic Names does not use the term, ''New York Harbor'' has important historical, governmental, commercial, and ecological usages. Overview The harbor is fed by the waters of the Hudson River (historically called the North River as it passes Manhattan), as well as the Gowanus Canal. It is connected to Lower New York Bay by the Na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turtle (submersible)
''Turtle'' (also called ''American Turtle'') was the world's first submersible vessel with a documented record of use in combat. It was built in 1775 by American David Bushnell as a means of attaching explosive charges to ships in a harbor, for use against Royal Navy vessels occupying American harbors during the American Revolutionary War. Connecticut Governor Jonathan Trumbull recommended the invention to George Washington, who provided funds and support for the development and testing of the machine. Several attempts were made using ''Turtle'' to affix explosives to the undersides of British warships in New York Harbor in 1776. All failed, and her transport ship was sunk later that year by the British with the submarine aboard. Bushnell claimed eventually to have recovered the machine, but its final fate is unknown. Modern replicas of ''Turtle'' have been constructed and are on display in the Connecticut River Museum, the U.S. Navy's Submarine Force Library and Museum ...

Frogman
A frogman is someone who is trained in scuba diving or swimming underwater in a tactical capacity that includes military, and in some European countries, police work. Such personnel are also known by the more formal names of combat diver, combatant diver, or combat swimmer. The word ''frogman'' first arose in the stage name ''The Fearless Frogman'' of Paul Boyton in the 1870s and later was claimed by John Spence, an enlisted member of the U.S. Navy and member of the OSS Maritime Unit, to have been applied to him while he was training in a green waterproof suit. The term ''frogman'' is occasionally used to refer to a civilian scuba diver. Some sport diving clubs include the word ''Frogmen'' in their names. The preferred term by scuba users is ''diver'', but the ''frogman'' epithet persists in informal usage by non-divers, especially in the media and often referring to professional scuba divers, such as in a police diving role. In the U.S. military and intelligence commun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limpet Mine
A limpet mine is a type of naval mine attached to a target by magnets. It is so named because of its superficial similarity to the shape of the limpet, a type of sea snail that clings tightly to rocks or other hard surfaces. A swimmer or diver may attach the mine, which is usually designed with hollow compartments to give the mine just slight negative buoyancy, making it easier to handle underwater. Types of fuses Usually limpet mines are set off by a time fuse. They may also have an anti-handling device, making the mine explode if removed from the hull by enemy divers or by explosions. Sometimes limpet mines have been fitted with a small turbine which would detonate the mine after the ship had sailed a certain distance, so that it was likely to sink in navigable channels (to make access difficult for other ships) or deep water (out of reach of easy salvage) and making determination of the cause of the sinking more difficult. Development In December 1938, a new unit wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
