Battle Of Cruces
The battle of Cruces was a naval confrontation between the Peruvian and the Gran Colombian navy which occurred from 22 to 24 November 1828. The following blockade of the port of Guayaquil by the Peruvian Navy proved decisive in obtaining maritime dominance during the war and subsequently marked the end of the naval campaign between Peru and Gran-Colombia. Background Following the naval battle of Punta Malpelo on 31 August 1828 which saw the Peruvian navy victorious over that of Gran-Colombia, the Peruvian navy next set their sights on the strategic port of Guayaquil in modern-day Ecuador. The Peruvian navy assembled a fleet consisting of the Frigate ''Presidente'', Corvette ''Libertad'' (a veteran of the battle of Punta Malpeto) and Schooner ''Peruviana'' under the command of Vice Admiral Martin George Guisse with the goal of capturing the port and establishing a naval blockade. A number of raids were conducted by the fleet near Guayaquil before the decision was made to attack ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gran Colombia–Peru War
The Gran Colombia–Peru War (Spanish: ''Guerra Grancolombo-Peruana'') of 1828 and 1829 was the first international conflict fought by the Republic of Peru, which had gained its independence from Spain in 1821, and Gran Colombia, that existed between 1819 and 1830. Causes The issues that led to war were Gran Colombian claims, dating from colonial times, concerning control of the territories of Jaén and Maynas. The Royal Audience of Quito ( es, Real Audiencia de Quito) was established in 1563 by a royal decree of the King of Spain. Its territories included, to the north, Pasto, Popayán, Cali, Buenaventura, and Buga in what is now Colombia. The Royal Audience of Quito was initially part of the Viceroyalty of Peru until 1717, when it became part of the Viceroyalty of New Granada. Borders at the time were imprecise, especially in the eastern unsettled areas, beyond the Andean cordillera, because of a lack of geographical knowledge and the low importance accorded to thes ...

Blockade
A blockade is the act of actively preventing a country or region from receiving or sending out food, supplies, weapons, or communications, and sometimes people, by military force. A blockade differs from an embargo or sanction, which are legal barriers to trade rather than physical barriers. It is also distinct from a siege in that a blockade is usually directed at an entire country or region, rather than a fortress or city and the objective may not always be to conquer the area. While most blockades historically took place at sea, blockades are also used on land to prevent entrance of an area. For example, Armenia is a landlocked country that Turkey and Azerbaijan blockade. Thus, Armenia cannot conduct international trade through those countries, and mainly trades through Georgia. This restricts the country's economic development. A blockading power can seek to cut off all maritime transport from and to the blockaded country; although stopping all land transp ...

Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or "tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see '' Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude tides a day—is a third regular category. Tides va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Organization
Military organization or military organisation is the structuring of the armed forces of a State (polity), state so as to offer such military capability as a military policy, national defense policy may require. In some countries paramilitary forces are included in a nation's armed forces, though not considered military. Armed forces that are not a part of military or paramilitary organizations, such as Insurgency, insurgent forces, often mimic military organizations, or use ''ad hoc'' structures, while formal military organization tends to use hierarchical forms. History The use of formalized Military rank, ranks in a hierarchical structure came into widespread use with the Roman Army. In modern times, executive control, management and administration of military organization is typically undertaken by governments through a Ministry (government department), government department within the structure of public administration, often known as a Ministry of defence, ministry ...

Counterattack
A counterattack is a tactic employed in response to an attack, with the term originating in " war games". The general objective is to negate or thwart the advantage gained by the enemy during attack, while the specific objectives typically seek to regain lost ground or destroy the attacking enemy (this may take the form of an opposing sports team or military units). A saying, attributed to Napoleon Bonaparte illustrate the tactical importance of the counterattack : "the greatest danger occurs at the moment of victory". In the same spirit, in his Battle Studies, Ardant du Pic noticed that "he, general or mere captain, who employs every one in the storming of a position can be sure of seeing it retaken by an organised counter-attack of four men and a corporal". A counterattack is a military tactic that occurs when one side successfully defends off the enemy’s attack and begins to push the enemy back with an attack of its own. In order to perform a successful counterattack, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Admiral
Admiral is one of the highest ranks in some navies. In the Commonwealth nations and the United States, a "full" admiral is equivalent to a "full" general in the army or the air force, and is above vice admiral and below admiral of the fleet, or fleet admiral. Etymology The word in Middle English comes from Anglo-French , "commander", from Medieval Latin , . These evolved from the Arabic () – (), “king, prince, chief, leader, nobleman, lord, a governor, commander, or person who rules over a number of people,” and (), the Arabic article answering to “the.” In Arabic, admiral is also represented as (), where () means the sea. The 1818 edition of Samuel Johnson's ''A Dictionary of the English Language'', edited and revised by the Rev. Henry John Todd, states that the term “has been traced to the Arab. emir or amir, lord or commander, and the Gr. , the sea, q. d. ''prince of the sea''. The word is written both with and without the d, in other languages, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shoal
In oceanography, geomorphology, and geoscience, a shoal is a natural submerged ridge, bank, or bar that consists of, or is covered by, sand or other unconsolidated material and rises from the bed of a body of water to near the surface. It often refers to those submerged ridges, banks, or bars that rise near enough to the surface of a body of water as to constitute a danger to navigation. Shoals are also known as sandbanks, sandbars, or gravelbars. Two or more shoals that are either separated by shared troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The term ''shoal'' is also used in a number of ways that can be either similar or quite different from how it is used in geologic, geomorphic, and oceanographic literature. Sometimes, this term refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Punta Malpelo
The Battle of Punta Malpelo was a naval encounter between a Peruvian corvette and two Gran Colombian vessels on 31 August 1828, near the port of Guayaquil, and was the first major combat of the Peruvian Navy as an independent force of the newborn Peruvian nation. Background In June 1828, Gran Colombia declared a state of war on Peru under allegations that it had fomented a rebellion against Colombian forces in Bolivia. Gran Colombia's leader, Simon Bolivar, also demanded the payment of a debt of several million pesos resulting from the Peruvian War of Independence; and the cession of the northern provinces of Jaén and Maynas. The consequent Peruvian declaration of war against Gran Colombia occurred on 3 July 1828 when the Peruvian government, under President Jose de La Mar, ordered a mobilization of its ground and naval forces. Battle On 2 July 1828, the Peruvian corvette ''Libertad'' armed with 24 guns and a crew of 124 men under Captain Carlos Garcia del Postigo (a Chilean- ...

Arson
Arson is the crime of willfully and deliberately setting fire to or charring property. Although the act of arson typically involves buildings, the term can also refer to the intentional burning of other things, such as motor vehicles, watercraft, or forests. The crime is typically classified as a felony, with instances involving a greater degree of risk to human life or property carrying a stricter penalty. Arson which results in death can be further prosecuted as manslaughter or murder. A common motive for arson is to commit insurance fraud. In such cases, a person destroys their own property by burning it and then lies about the cause in order to collect against their insurance policy. A person who commits arson is referred to as an arsonist, or a serial arsonist if arson has been committed several times. Arsonists normally use an accelerant (such as gasoline or kerosene) to ignite, propel and directionalize fires, and the detection and identification of ignitable ...

Scuttling
Scuttling is the deliberate sinking of a ship. 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-destruction to prevent the ship from being captured by an enemy force (or, in the case of a vessel engaged in illegal activities, by the authorities); as a blockship to restrict navigation through a 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 preserved from the keel up to the decks in the silt was discovered alongside two smaller vessels in the river IJssel i ...

Fortification
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its ' cyclopean' walls). A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, th ...

Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bay ...
