Scuttling
Scuttling is the act of deliberately sinking a ship by allowing water to flow into the hull, typically by its crew opening holes in its hull. Scuttling may be performed to dispose of an abandoned, old, or captured vessel; to prevent the vessel from becoming a navigation hazard; as an act of self destruct, self-destruction to prevent the ship from being captured by an enemy force; as a blockship to restrict navigation through a Channel (geography), channel or within a harbor; to provide an artificial reef for divers and marine life; or to alter the flow of rivers. Notable historical examples Skuldelev ships (around 1070) The Skuldelev ships, five Viking ships, were sunk to prevent attacks from the sea on the Danish city of Roskilde. The scuttling blocked a major waterway, redirecting ships to a smaller one that required considerable local knowledge. Cog near Kampen (early 15th century) In 2012, a Cog (ship), cog preserved from the keel up to the decks in the silt was dis ...

Self Destruct
A self-destruct is a mechanism that can cause an object to destroy itself or render itself inoperable after a predefined set of circumstances has occurred. Self-destruct mechanisms are typically found on devices and systems where malfunction could endanger large numbers of people. Uses Land mines Some types of modern land mines are designed to self-destruct, or chemically render themselves inert after a period of weeks or months to reduce the likelihood of friendly casualties during the conflict or civilian casualties after the conflict's end. The Amended Protocol II to the Convention on Certain Conventional Weapons (CCW), amended in 1996, requires that anti-personnel land mines deactivate and self-destruct, and sets standards for both. Landmines currently used by the United States military are designed to self-destruct after between 4 hours and 15 days depending upon the type. The landmines have a battery and when the battery dies, the land mine self-destructs. The self-d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bay Bulls, Newfoundland And Labrador
Bay Bulls ( 2021 population: 1,566) is a small fishing town in the province of Newfoundland and Labrador, Canada. Geography Located in a sheltered bay, it has been home to many fishermen and a strategic location in early times as it is located just a few miles from the capital, St. John's. History Bay Bulls first appears on a 1592 map drawn by Thomas Hood. Fortification of the harbour came in 1638 by Governor David Kirke. In 1665, Bay Bulls was raided by Dutch sailors under Admiral De Ruyter. During King William's War, the village was attacked twice. In 1696, Monbeton de St. Ovide de Brouillan, the governor of Placentia, attacked Bay Bulls from the sea, resulting in the scuttling of the English warship HMS Sapphire. Then in 1697 Pierre Le Moyne d'Iberville marched overland from Placentia and attacked Bay Bulls in the Avalon Peninsula Campaign. In 1702, Commodore John Leake of the Royal Navy entered Bay Bulls with several Men of War, and received information about the ...

Spanish Conquest Of The Aztec Empire
The Spanish conquest of the Aztec Empire was a pivotal event in the history of the Americas, marked by the collision of the Aztec Triple Alliance and the Spanish Empire. Taking place between 1519 and 1521, this event saw the Spanish conquistador Hernán Cortés, and his small army of European soldiers and numerous indigenous allies, overthrowing one of the most powerful empires in Mesoamerica. Led by the Aztec ruler Moctezuma II, the Aztec Empire had established dominance over central Mexico through military conquest and intricate alliances. Because the Aztec Empire ruled via hegemonic control by maintaining local leadership and relying on the psychological perception of Aztec power — backed by military force — the Aztecs normally kept subordinate rulers compliant. This was an inherently unstable system of governance, as this situation could change with any alteration in the status quo. A combination of factors including superior weaponry, strategic alliances with oppresse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hernán Cortés
Hernán Cortés de Monroy y Pizarro Altamirano, 1st Marquis of the Valley of Oaxaca (December 1485 – December 2, 1547) was a Spanish ''conquistador'' who led an expedition that caused the fall of the Aztec Empire and brought large portions of what is now mainland Mexico under the rule of the King of Castile in the early 16th century. Cortés was part of the generation of Spanish explorers and conquistadors who began the first phase of the Spanish colonization of the Americas. Born in Medellín, Spain, to a family of lesser nobility, Cortés chose to pursue adventure and riches in the New World. He went to Hispaniola and later to Cuba, where he received an ''encomienda'' (the right to the labor of certain subjects). For a short time, he served as ''alcalde'' (magistrate) of the second Spanish town founded on the island. In 1519, he was elected captain of the third expedition to the mainland, which he partly funded. His enmity with the governor of Cuba, Diego Velázquez de Cué ...

Sinking
Shipwrecking is any event causing a ship to wreck, such as a collision causing the ship to sink; the stranding of a ship on rocks, land or shoal; poor maintenance, resulting in a lack of seaworthiness; or the destruction of a ship either intentionally or by violent weather. The resulting physical remains of a wrecked ship are called ''shipwreck''. Causes Factors for the loss of a ship may include: * poor design or failure of the ship's equipment or hull - pressure hull * instability, due to poor design, improperly stowed cargo, cargo that shifts its position or the free surface effect * navigation errors and other human errors, leading to collisions (with another ship, rocks, an iceberg (), etc.) or running aground (''Costa Concordia'') * bad weather and powerful or large waves or gale winds: This often leads to a vessel being swamped by waves, holed on rocks or a reef, or capsizing, also referred to as ''foundering'' * warfare, piracy, mutiny, or sabotage including: guns, ...

Artificial Reef
An artificial reef (AR) is a human-created freshwater or marine benthic structure. Typically built in areas with a generally featureless bottom to promote Marine biology#Reefs, marine life, it may be intended to control #Erosion prevention, erosion, protect coastal areas, block ship passage, block the use of trawling nets, support reef restoration, improve aquaculture, or enhance scuba diving and surfing. Early artificial reefs were built by the Persians and the Romans. An opportunity artificial reef is built from objects that were intended for other purposes, such as sinking oil rigs (through the Rigs-to-Reefs program), Sinking ships for wreck diving sites, scuttling ships, or by deploying rubble or construction debris. Shipwrecks may become artificial reefs when preserved on the seafloor. A conventional artificial reef uses materials such as concrete, which can be molded into specialized forms (e.g. The Reef Ball Foundation, reef balls). Green artificial reefs incorporate renewab ...

HMS Endeavour
HMS ''Endeavour'' was a British Royal Navy research vessel that Lieutenant James Cook commanded to Tahiti, New Zealand and Australia on his First voyage of James Cook, first voyage of discovery from 1768 to 1771. She was launched in 1764 as the Collier (ship type), collier ''Earl of Pembroke'', with the Navy purchasing her in 1768 for a scientific mission to the Pacific Ocean and to explore the seas for the surmised ''Terra Australis, Terra Australis Incognita'' or "unknown southern land". Commissioned as His Majesty's Bark ''Endeavour'', she departed Plymouth in August 1768, rounded Cape Horn and reached Tahiti in time to observe the 1769 transit of Venus across the Sun. She then set sail into the largely uncharted ocean to the south, stopping at the islands of Huahine, Bora Bora, and Raiatea west of Tahiti to allow Cook to claim them for Great Britain. In September 1769, she anchored off New Zealand, becoming the first European vessel to reach the islands since Abel Tasman's ...

James Cook
Captain (Royal Navy), Captain James Cook (7 November 1728 – 14 February 1779) was a British Royal Navy officer, explorer, and cartographer famous for his three voyages of exploration to the Pacific and Southern Oceans, conducted between 1768 and 1779. He completed the first recorded circumnavigation of the main islands of New Zealand and was the first known European to visit the eastern coastline of Australia and the Hawaiian Islands. Cook joined the British merchant navy as a teenager before enlisting in the Royal Navy in 1755. He served during the Seven Years' War, and subsequently surveyed and mapped much of the entrance to the St. Lawrence River during the Battle of the Plains of Abraham, siege of Quebec. In the 1760s, he mapped the coastline of Newfoundland (island), Newfoundland and made important astronomical observations which brought him to the attention of the Admiralty (United Kingdom), Admiralty and the Royal Society. This acclaim came at a crucial moment in Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frigate
A frigate () is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied. The name frigate in the 17th to early 18th centuries was given to any full-rigged ship built for speed and maneuverability, intended to be used in scouting, escort and patrol roles. The term was applied loosely to ships varying greatly in design. In the second quarter of the 18th century, what is now generally regarded as the 'true frigate' was developed in France. This type of vessel was characterised by possessing only one armed deck, with an unarmed deck below it used for berthing the crew. Late in the 19th century (British and French prototypes were constructed in 1858), a type of powerful ironclad warships was developed, and because they had a single gun deck, the term 'frigate' was used to describe them. Later developments in ironclad ships rendered the 'frigate' designation obsolete and the term fell out of favour. During the Second World War ...

Fifth-rate
In the rating system of the Royal Navy used to categorise sailing warships, a fifth rate was the second-smallest class of warships in a hierarchical system of six " ratings" based on size and firepower. Rating The rating system in the Royal Navy as originally devised had just four rates, but early in the reign of Charles I, the original fourth rate (derived from the "Small Ships" category under his father, James I) was divided into new classifications of fourth, fifth, and sixth rates. While a fourth-rate ship was defined as a ship of the line, fifth and the smaller sixth-rate ships were never included among ships-of-the-line. Nevertheless, during the Anglo-Dutch Wars of the 17th century, fifth rates often found themselves involved among the battle fleet in major actions. Structurally, these were two-deckers, with a complete battery on the lower deck, and fewer guns on the upper deck (below the forecastle and quarter decks, usually with no guns in the waist on this deck). ...

HMS Sapphire (1675)
HMS ''Sapphire'' was a 32-gun fifth rate of the Royal Navy, scuttled at Bay Bulls, Newfoundland, Canada in 1696. It is currently a protected archaeological site. She was the only vessel of any size sunk in the Anglo-French wars in North America. History HMS ''Sapphire'' (also spelled ''Saphire,'' and called ''Zephyr'' by the French) was designed and built by Sir Anthony Deane (mayor), Anthony Deane at Harwich in 1675, at a cost of £4,175. In 1677, ''Sapphire'' was the first command of Cloudesley Shovell, who later became Admiral of the Fleet (Royal Navy), Admiral of the Fleet and eventually died in the Scilly naval disaster of 1707. The warship left England during King Williams’s War in April 1696 with orders to escort fishing vessels across the North Atlantic and protect them from the French, and remained active in the waters around Newfoundland after its initial escort task. The ship was under the command of Captain Thomas Cleasby, accompanied by Lieutenant James Brother ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
