Coastal Defence And Fortification
300px, Cartagena_de_Indias.html" ;"title="Castillo San Felipe de Barajas in Cartagena de Indias">Castillo San Felipe de Barajas in Cartagena de Indias, Colombia Coastal defence (or defense) and coastal fortification are measures taken to provide protection against military attack at or near a coastline (or other shoreline), for example, fortifications and coastal artillery. Because an invading enemy normally requires a port or harbour to sustain operations, such defences are usually concentrated around such facilities, or places where such facilities could be constructed. Coastal artillery fortifications generally followed the development of land fortifications, usually incorporating land defences; sometimes separate land defence forts were built to protect coastal forts. Through the middle 19th century, coastal forts could be bastion forts, star forts, polygonal forts, or sea forts, the first three types often with detached gun batteries called "water batteries".

Controlled Mines
A controlled mine was a circuit fired weapon used in coastal defenses with ancestry going back to 1805 when Robert Fulton termed his underwater explosive device a torpedo: Robert Fulton invented the word torpedo to describe his underwater explosive device and successfully destroyed a ship in 1805. In the 1840s Samuel Colt began experimenting with underwater mines fired by electric current and in 1842, he blew up an old schooner in the Potomac River from a shore station five miles away. History "Torpedoes" were in use during the American Civil War when such devices were made famous with the order given by David Farragut at Mobile Bay. After that war similar mines were being contemplated or put into use by other nations. In 1869 the United States Army Corps of Engineers was directed by Secretary of War William Belknap to assume responsibility for torpedoes for coastal defense. That responsibility continued through the formation of the U.S. Torpedo Service as part of the United Sta ...

Viking
Vikings were seafaring people originally from Scandinavia (present-day Denmark, Norway, and Sweden), who from the late 8th to the late 11th centuries raided, pirated, traded, and settled throughout parts of Europe.Roesdahl, pp. 9–22. They also voyaged as far as the Mediterranean Sea, Mediterranean, North Africa, the Middle East, Greenland, and Vinland (present-day Newfoundland in Canada, North America). In their countries of origin, and some of the countries they raided and settled in, this period is popularly known as the Viking Age, and the term "Viking" also commonly includes the inhabitants of the Scandinavian homelands as a whole. The Vikings had a profound impact on the Early Middle Ages, early medieval history of Northern Europe, northern and Eastern Europe, including the political and social development of England (and the English language) and parts of France, and established the embryo of Russia in Kievan Rus'.

Wessex
The Kingdom of the West Saxons, also known as the Kingdom of Wessex, was an Anglo-Saxon Heptarchy, kingdom in the south of Great Britain, from around 519 until Alfred the Great declared himself as King of the Anglo-Saxons in 886. The Anglo-Saxons believed that Wessex was founded by Cerdic and Cynric of the Gewisse, though this is considered by some to be a legend. The two main sources for the history of Wessex are the West Saxon Genealogical Regnal List and the ''Anglo-Saxon Chronicle'' (the latter of which drew on and adapted an early version of the List), which sometimes conflict. Wessex became a Christianity, Christian kingdom after Cenwalh () was baptised and was expanded under his rule. Cædwalla later conquered Kingdom of Sussex, Sussex, Kingdom of Kent, Kent and the Isle of Wight. His successor, Ine of Wessex, Ine (), issued one of the oldest surviving English law codes and established a second West Saxon bishopric. The throne subsequently passed to a series of kings wit ...

History During the Republic The Roman Republic's influence began in southern Gaul. By the mid-2nd century BC, Rome was trading heavily with the Greek colony of Massalia, Massilia (modern Marseille) and entered into an alliance with them, by which Rome agreed to protect the town from local Gauls, including the nearby Aquitani and from sea-borne Carthaginians and other rivals, in exchange for land that the Romans wanted in order to build a road to Hispania to improve troop movements to its provinces there. The Mediterranean settlements on the coast continued to be threatened by the powerful Gallic tribes to the north and in 122 BC the Roman general Gnaeus Domitius Ahenobarbus (consul 122 BC), Gnaeus Domitius Ahe ...

Roman Britain
Roman Britain was the territory that became the Roman province of ''Britannia'' after the Roman conquest of Britain, consisting of a large part of the island of Great Britain. The occupation lasted from AD 43 to AD 410. Julius Caesar invaded Britain in 55 and 54 BC as part of his Gallic Wars. According to Caesar, the Britons had been overrun or culturally assimilated by the Belgae during the British Iron Age and had been aiding Caesar's enemies. The Belgae were the only Celtic tribe to cross the sea into Britain, for to all other Celtic tribes this land was unknown. He received tribute, installed the friendly king Mandubracius over the Trinovantes, and returned to Gaul. Planned invasions under Augustus were called off in 34, 27, and 25 BC. In 40 AD, Caligula assembled 200,000 men at the Channel on the continent, only to have them gather seashells () according to Suetonius, perhaps as a symbolic gesture to proclaim Caligula's victory over th ...

Saxon Shore
The Saxon Shore () was a military command of the Late Roman Empire, consisting of a series of fortifications on both sides of the English Channel. It was established in the late 3rd century and was led by the " Count of the Saxon Shore". In the late 4th century, his functions were limited to Britain, while the fortifications in Gaul were established as separate commands. Several well-preserved Saxon Shore forts survive in east and south-east England. Background During the latter half of the 3rd century, the Roman Empire faced a grave crisis: Weakened by civil wars, the rapid succession of short-lived emperors, and secession in the provinces, the Romans now faced new waves of attacks by barbarian tribes. Most of Britain had been part of the empire since the mid-1st century. It was protected from raids by native Celtic Britons in the north by the Hadrianic and Antonine Walls, while a fleet of some size was also available. However, as the frontiers came under increasing extern ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Amphibious Warfare
Amphibious warfare is a type of offensive military operation that today uses naval ships to project ground and air power onto a hostile or potentially hostile shore at a designated landing beach. Through history the operations were conducted using ship's boats as the primary method of delivering troops to shore. Since the Gallipoli Campaign, specialised watercraft were increasingly designed for landing troops, material and vehicles, including by landing craft and for insertion of commandos, by fast patrol boats, zodiacs (rigid inflatable boats) and from mini-submersibles. The term ''amphibious'' first emerged in the United Kingdom and the United States during the 1930s with introduction of vehicles such as Vickers-Carden-Loyd Light Amphibious Tank or the Landing Vehicle Tracked.The first LVT prototypes were named '' Alligator'' and '' Crocodile'', though neither species is actual amphibian Amphibious warfare includes operations defined by their type, purpose, sca ...

Marines
Marines (or naval infantry) are military personnel generally trained to operate on both land and sea, with a particular focus on amphibious warfare. Historically, the main tasks undertaken by marines have included Raid (military), raiding ashore (often in support of naval objectives) and the Boarding (attack), boarding of vessels during naval warfare, ship-to-ship combat or capture of Prize (law), prize ships. Marines also assisted in maintaining security, discipline, and order aboard ships (reflecting the historically Impressment, pressed-nature of the rest of the ship's company and the risk of mutiny). While maintaining many of their historical roles, in modern times, marines also engage in duties including Rapid reaction force, rapid-response operations, humanitarian aid, disaster relief, special forces, special operations roles, and counter-terrorism, counter-terrorism operations. In most nations, marines are an integral part of that state's navy, such as the United Kingdom's ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Naval Artillery
Naval artillery is artillery mounted on a warship, originally used only for naval warfare and then subsequently used for more specialized roles in surface warfare such as naval gunfire support (NGFS) and anti-aircraft warfare (AAW) engagements. The term generally refers to powder-launched projectile-firing weapons and excludes self-propelled projectiles such as torpedoes, rockets, and missiles and those simply dropped overboard such as depth charges and naval mines. Origins The idea of ship-borne artillery dates back to the classical era. Julius Caesar wrote about the Roman navy's usage of ship-borne catapults against Celtic Britons ashore in his ''Commentarii de Bello Gallico''. The dromons of the Byzantine Empire carried catapults and Greek fire. From the Middle Ages onwards, warships began to carry cannons of various calibres. In the Battle of Tangdao in 1161, the Southern Song general Li Bao used huopao (a type of gunpowder weapons, possibly cannons) and fire arro ...
