More of the anti-aircraft guns were deployed to the airstrip at Goose Green. Lockheed Hercules transport night flights brought supplies, weapons, vehicles, and fuel, and airlifted out
1323-864: A monopoly in the islands. In 1977, the British prime minister, James Callaghan , in response to heightened tensions in the region and the Argentine occupation of Southern Thule , secretly sent a force of two frigates and a nuclear-powered submarine , HMS Dreadnought , to the South Atlantic, codenamed Operation Journeyman . It is unclear whether the Argentines were aware of their presence, but British sources state that they were advised of it through informal channels. Nevertheless, talks with Argentina on Falklands sovereignty and economic cooperation opened in December of that year, though they proved inconclusive. In 1980,

Admiral Woodward
2205-457: A signal to the Argentines that the UK was unwilling, and would soon be unable, to defend its territories and subjects in the Falklands. On 2 April 1982, Argentine forces mounted amphibious landings, known as Operation Rosario, on the Falkland Islands. The invasion was met with a fierce but brief defence organised by the Falkland Islands' Governor Sir Rex Hunt , giving command to Major Mike Norman of

Atlantic Ocean The Atlantic Ocean is the second-largest of the world's five oceanic divisions , with an area of about 85,133,000 km (32,870,000 sq mi). It covers approximately 17% of Earth's surface and about 24% of its water surface area. During
11466-644: The east, and the Americas to the west. As one component of the interconnected World Ocean , it is connected in the north to the Arctic Ocean , to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south. Other definitions describe the Atlantic as extending southward to Antarctica . The Atlantic Ocean is divided in two parts, the northern and southern Atlantic, by
11613-596: The east, the boundaries of the ocean proper are Europe: the Strait of Gibraltar (where it connects with the Mediterranean Sea – one of its marginal seas – and, in turn, the Black Sea , both of which also touch upon Asia) and Africa. In the southeast, the Atlantic merges into the Indian Ocean. The 20° East meridian , running south from Cape Agulhas to Antarctica defines its border. In
11760-544: The eastern and western North Atlantic central water since the western part is strongly affected by the Gulf Stream and therefore the upper layer is closer to underlying fresher subpolar intermediate water. The eastern water is saltier because of its proximity to Mediterranean water. North Atlantic central water flows into South Atlantic central water at 15°N . There are five intermediate waters: four low-salinity waters formed at subpolar latitudes and one high-salinity formed through evaporation. Arctic intermediate water flows from
11907-524: The edge of Argentina's 12-nautical-mile (22 km; 14 mi) territorial limit to provide early warning of bombing raids on the British task force. Operation Folklore was a plan to deploy two Canberra PR.9 aircraft of No. 39 Squadron RAF , disguised in Chilean Air Force markings, to the Chilean air base at Punta Arenas , with the intention of undertaking high-level photo-reconnaissance flights over
12054-409: The fighting. This had the secondary effect of allowing the British to redeploy their nuclear submarines to the coast of Argentina, where they were able to provide early warning of outgoing air attacks leaving mainland bases. However, settling the controversy in 2003, the ship's captain, Hector Bonzo, stated to a documentary crew that General Belgrano had actually been manoeuvring, not sailing away from
12201-486: The first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus' expedition ushered in an age of exploration and colonization of the Americas by European powers , most notably Portugal , Spain , France , and the United Kingdom . From the 16th to 19th centuries, the Atlantic Ocean was the center of both an eponymous slave trade and
12348-512: The first landing, survey and mapping of South Georgia. As mandated by the Admiralty , on 17 January 1775 he took possession for Britain and renamed the island 'Isle of Georgia' for King George III . After making a foot crossing of the island with Tom Crean and Frank Worsley , Ernest Shackleton organised the rescue of his party from Elephant Island following the disaster that befell the 1916 Imperial Trans-Antarctic Expedition , which he led. He
12495-499: The five Black Buck raids, three were against Stanley Airfield, with the other two being anti-radar missions using Shrike anti-radiation missiles . The Falklands had only three airfields. The longest and only paved runway was at the capital, Stanley , and even that was too short to support fast jets. Therefore, the Argentines were forced to launch their major strikes from the mainland, severely hampering their efforts at forward staging, combat air patrols , and close air support over
12642-549: The freezing water on the mountainside." Private Rito Portillo from the 1st Marine Anti-Aircraft Battalion and Private Remigio Fernández from the 5th Regiment were reported to have been executed or died because of mistreatment by their own officers. Soldiers were made to sign non-disclosure documents on their return from the Islands. On 8 April, Alexander Haig , the United States Secretary of State , arrived in London on
12789-461: The island, intending to live there through the winter. However, in May, three months into the experiment, surge waves destroyed his camp. He managed to salvage enough gear to survive the winter until making contact with a ship 116 days later. His knowledge and mapping proved helpful to the British during the Falklands conflicts. On 19 March 1982, a group of Argentinians arrived at Leith Harbour and raised
12936-404: The islanders steadfastly refused to consider Argentine sovereignty on one side, whilst Argentina would not compromise over sovereignty on the other. The FCO then sought to make the islands dependent on Argentina, hoping this would make the islanders more amenable to Argentine sovereignty. A Communications Agreement signed in 1971 created an airlink and later YPF, the Argentine oil company, was given
13083-530: The islands a war zone. The conflict had a strong effect in both countries and has been the subject of various books, articles, films, and songs . Patriotic sentiment ran high in Argentina, but the unfavourable outcome prompted large protests against the ruling military government , hastening its downfall and the democratisation of the country . In the United Kingdom, the Conservative government, bolstered by
13230-442: The islands and by using a late pop up profile. Meanwhile, other Argentine aircraft were intercepted by BAE Sea Harriers operating from HMS Invincible . A Dagger and a Canberra were shot down. Combat broke out between Sea Harrier FRS Mk 1 fighters of No. 801 Naval Air Squadron and Mirage III fighters of Grupo 8. Both sides refused to fight at the other's best altitude, until two Mirages finally descended to engage. One
13377-537: The islands as a nuisance and barrier to UK trade in South America. Therefore, while confident of British sovereignty, the FCO was prepared to cede the islands to Argentina. When news of a proposed transfer broke in 1968, elements sympathetic with the plight of the islanders were able to organise an effective parliamentary lobby to frustrate the FCO plans. Negotiations continued, but in general failed to make meaningful progress;
13524-429: The islands to British control. In total, 649 Argentine military personnel, 255 British military personnel, and three Falkland Islanders were killed during the hostilities. The conflict was a major episode in the protracted dispute over the territories' sovereignty . Argentina asserted (and maintains) that the islands are Argentine territory, and the Argentine government thus described its military action as
13671-619: The islands. For almost a month, the civilian population of Goose Green was detained in the village hall in "unpleasant conditions". Less well known are similar detentions in other outlying settlements, including one islander who died after being denied access to his medication. As the war's end approached, some troops began to place booby traps in civilian homes, defiled homes with excrement, destroyed civilian property and committed arson against civilian properties. Argentine officers and NCOs have been accused of handing out rough Field punishment to their conscript soldiers. Ration packs from
13818-415: The islands. The effective loiter time of incoming Argentine aircraft was low, limiting the ability of fighters to protect attack aircraft, which were often compelled to attack the first target of opportunity, rather than selecting the most lucrative target. The first major Argentine strike force comprised 36 aircraft ( A-4 Skyhawks , IAI Daggers , English Electric Canberras , and Mirage III escorts), and
13965-579: The islands. The total Argentine garrison numbered some 13,000 troops by the beginning of May. The conscripts born in 1963 had only recently been called-up, so they were supplemented by the recall of the previous year's intake. Brigadier General Mario Benjamín Menéndez was appointed Military Governor of the Malvinas. Argentine military police arrived with detailed files on many islanders, allowing intelligence officer Major Patricio Dowling to arrest and interrogate islanders who he suspected might lead opposition to
14112-415: The junta's dwindling legitimacy. The newspaper La Prensa speculated on a step-by-step plan beginning with cutting off supplies to the islands, ending in direct actions late in 1982, if the UN talks were fruitless. The ongoing tension between the two countries over the islands increased on 19 March, when a group of Argentine scrap metal merchants (which had been infiltrated by Argentine Marines ) raised
14259-552: The last on 17 May narrowly avoided being shot down by the Chileans, leading to the cancellation of the operation. More successful was Operation Fingent, the placement of a Marconi S259 radar on high ground in Tierra del Fuego from where it could monitor movements at southern Argentinian air bases; the RAF crew wore civilian clothes in the guise of a sales team. Information was passed to Northwood and
14406-510: The latter 2,000 km (1,200 mi). Ocean currents such as the Gulf Stream transport eel larvae from the Sargasso Sea to foraging areas in North America, Europe, and northern Africa. Recent but disputed research suggests that eels possibly use Earth's magnetic field to navigate through the ocean both as larvae and as adults. The climate is influenced by the temperatures of the surface waters and water currents as well as winds. Because of
14553-645: The limits of the oceans and seas in 1953, but some of these definitions have been revised since then and some are not recognized by various authorities, institutions, and countries, for example the CIA World Factbook . Correspondingly, the extent and number of oceans and seas vary. The Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait , Greenland Sea , Norwegian Sea and Barents Sea . To
14700-492: The lowest values are in the high latitudes and along coasts where large rivers enter. Maximum salinity values occur at about 25° north and south , in subtropical regions with low rainfall and high evaporation. The high surface salinity in the Atlantic, on which the Atlantic thermohaline circulation is dependent, is maintained by two processes: the Agulhas Leakage/Rings , which brings salty Indian Ocean waters into
14847-508: The margins of the continents constitute about 11% of the bottom topography with few deep channels cut across the continental rise. The mean depth between 60°N and 60°S is 3,730 m (12,240 ft), or close to the average for the global ocean, with a modal depth between 4,000 and 5,000 m (13,000 and 16,000 ft). In the South Atlantic the Walvis Ridge and Rio Grande Rise form barriers to ocean currents. The Laurentian Abyss
14994-635: The maximum depth, the Milwaukee Deep in the Puerto Rico Trench , is 8,376 m (27,480 ft). Top large seas: The bathymetry of the Atlantic is dominated by a submarine mountain range called the Mid-Atlantic Ridge (MAR). It runs from 87°N or 300 km (190 mi) south of the North Pole to the subantarctic Bouvet Island at 54°S . Expeditions to explore the bathymertry of
15141-497: The mid- Atlantic British overseas territory of Ascension Island . They included a sizeable force of Avro Vulcan B Mk 2 bombers, Handley Page Victor K Mk 2 refuelling aircraft , and McDonnell Douglas Phantom FGR Mk 2 fighters to protect them. Meanwhile, the main British naval task force arrived at Ascension to prepare for active service. A small force had already been sent south to recapture South Georgia. Encounters began in April;
15288-507: The midst of devastating economic stagnation and large-scale civil unrest against the National Reorganization Process , the military junta that had been governing the country since 1976. In December 1981, there was a further change in the Argentine military regime, bringing to office a new junta headed by General Leopoldo Galtieri (acting president), Air Brigadier Basilio Lami Dozo and Admiral Jorge Anaya . Anaya
15435-718: The most extensive and voluminous large igneous provinces in Earth's history associated with the Triassic–Jurassic extinction event , one of Earth's major extinction events . Theoliitic dikes , sills , and lava flows from the CAMP eruption at 200 Ma have been found in West Africa, eastern North America, and northern South America. The extent of the volcanism has been estimated to 4.5 × 10 km (1.7 × 10 sq mi) of which 2.5 × 10 km (9.7 × 10 sq mi) covered what
15582-640: The news to the media, telling them to "Just rejoice at that news, and congratulate our forces and the Marines!" On 1 May, British operations on the Falklands opened with the "Black Buck 1" attack (of a series of five) on the airfield at Stanley. A Vulcan bomber from Ascension flew an 8,000-nautical-mile (15,000 km; 9,200 mi) round trip, dropping conventional bombs across the runway at Stanley. The mission required repeated aerial refuelling using several Victor K2 tanker aircraft operating in concert, including tanker-to-tanker refuelling. The overall effect of
15729-551: The night of the invasion, a banquet was held at Roca's official residence for the US ambassador to the UN, Jeane Kirkpatrick , and several high-ranking officials of the United States Department of State and the United States Department of Defense . This led British diplomats to view Kirkpatrick, who had earlier called for closer relationships with South American dictatorships, with considerable suspicion. On 1 April, London told
15876-540: The night, and Mirage IIIs (without air refuelling capability or any capable AAM) as decoys to lure away the British Sea Harriers. The decoying would be later extended with the formation of the Escuadrón Fénix , a squadron of civilian jets flying 24 hours a day, simulating strike aircraft preparing to attack the fleet. On one of these flights on 7 June, an Air Force Learjet 35 A was shot down by HMS Exeter, killing
16023-563: The north to become the source for North Atlantic deep water, south of the Greenland-Scotland sill. These two intermediate waters have different salinity in the western and eastern basins. The wide range of salinities in the North Atlantic is caused by the asymmetry of the northern subtropical gyre and a large number of contributions from a wide range of sources: Labrador Sea, Norwegian-Greenland Sea, Mediterranean, and South Atlantic Intermediate Water. The North Atlantic deep water (NADW)
16170-420: The occupation was the 25th Infantry Regiment , a unit of about 681 men specially trained from all the regions of Argentina ; it was flown into Port Stanley Airport as soon as the runway had been cleared. Once it became clear that the British were sending an amphibious task force, there was a general recall of reservists and two brigades of eight infantry regiments and their supporting units were dispatched to
16317-628: The occupation. Initially, Islanders suspected of holding anti-Argentine views were expelled, including the Luxton family (who had lived in the islands since the 1840s) and David Colville, editor of the Falklands Times . This proved to be counter-productive, as those expelled gave interviews to the press. Subsequently, fourteen other community leaders, including the senior medical officer, were interned at Fox Bay on West Falkland. Concerned by Dowling's actions, senior Argentine officers had him removed from
16464-416: The ocean liner SS Canberra was requisitioned and set sail two days later with the 3 Commando Brigade aboard. The ocean liner Queen Elizabeth 2 was also requisitioned, and left Southampton on 12 May, with the 5th Infantry Brigade on board. The whole task force eventually comprised 127 ships: 43 Royal Navy vessels, 22 Royal Fleet Auxiliary ships, and 62 merchant ships . The retaking of
16611-425: The ocean's great capacity to store and release heat, maritime climates are more moderate and have less extreme seasonal variations than inland climates. Precipitation can be approximated from coastal weather data and air temperature from water temperatures. The oceans are the major source of atmospheric moisture that is obtained through evaporation. Climatic zones vary with latitude; the warmest zones stretch across
16758-611: The outlines of the coasts of the Old and the New Worlds. The remainder of the ridge was discovered in the 1920s by the German Meteor expedition using echo-sounding equipment. The exploration of the MAR in the 1950s led to the general acceptance of seafloor spreading and plate tectonics . Most of the MAR runs under water but where it reaches the surfaces it has produced volcanic islands. While nine of these have collectively been nominated
16905-637: The pond" or "on the other side of the pond" or "across the pond", rather than to discuss the ocean itself. The term dates to 1640, first appearing in print in a pamphlet released during the reign of Charles I , and reproduced in 1869 in Nehemiah Wallington 's Historical Notices of Events Occurring Chiefly in The Reign of Charles I , where "great Pond" is used in reference to the Atlantic Ocean by Francis Windebank , Charles I's Secretary of State . The International Hydrographic Organization (IHO) defined
17052-542: The presence of a large Argentine fleet and that Argentine forces had taken control of the island. British military operations in the Falklands War were given the codename Operation Corporate , and the commander of the task force was Admiral Sir John Fieldhouse . Operations lasted from 1 April 1982 to 20 June 1982. On 6 April, the British Government set up a War Cabinet to provide day-to-day political oversight of
17199-456: The raids on the war is difficult to determine. The runway was cratered by only one of the twenty one bombs, but as a result, the Argentines realised that their mainland was vulnerable and fighter aircraft were redeployed from the theatre to bases further north. Historian Lawrence Freedman , who was given access to official sources, comments that the significance of the Vulcan raids remains a subject of controversy. Although they took pressure off
17346-409: The reclamation of its own territory. The British government regarded the action as an invasion of a territory that had been a Crown colony since 1841. Falkland Islanders, who have inhabited the islands since the early 19th century, are predominantly descendants of British settlers, and strongly favour British sovereignty . Neither state officially declared war , although both governments declared
17493-535: The remainder as strike aircraft , in Argentina's air forces during the war . Crucially, the British lacked airborne early warning and control (AEW) aircraft. Planning also considered the Argentine surface fleet and the threat posed by Exocet -equipped vessels or the two Type 209 submarines . By mid-April, the Royal Air Force had set up an airbase on RAF Ascension Island , co-located with Wideawake Airfield, on
17640-438: The seafloor. The oldest oceanic crust in the Atlantic is up to 145 million years and is situated off the west coast of Africa and the east coast of North America, or on either side of the South Atlantic. In many places, the continental shelf and continental slope are covered in thick sedimentary layers. For instance, on the North American side of the ocean, large carbonate deposits formed in warm shallow waters such as Florida and
17787-556: The ship, died in the incident. More than 700 men were eventually rescued from the open ocean despite cold seas and stormy weather, enduring up to 30 hours in overcrowded life rafts. The loss of General Belgrano drew heavy criticism from Latin American countries and from opponents of the war in Britain; support for the British cause wavered amongst some European allies, but the United States remained supportive. Regardless of controversies over
17934-418: The sinking — including disagreement about the exact nature of the exclusion zone and whether General Belgrano had been returning to port at the time of the sinking — it had a crucial strategic effect: the elimination of the Argentine naval threat. After her loss, the entire Argentine fleet, with the exception of the diesel-powered submarine ARA San Luis , returned to port and did not leave again during
18081-538: The small Sea Harrier force, the raids were costly and used a great deal of resources. The single hit to the edge of the runway was probably the best that could have been expected. Contrary to some reports, this reduced the capability of the runway to operate Mirage III fast jets but not other, smaller jet fighters, the Pucara , and the Hercules C-130 . Nor did it cause the Argentine air force to deploy Mirage IIIs to defend
18228-518: The sovereignty of the Falkland Islands was made explicit. In 1994, Argentina adopted a new constitution , which declared the Falkland Islands as part of one of its provinces by law. However, the islands continue to operate as a self-governing British Overseas Territory . In 1965, the United Nations called upon Argentina and the United Kingdom to reach a settlement of the sovereignty dispute. The UK Foreign and Commonwealth Office (FCO) regarded
18375-460: The squadron commander, Vice Commodore Rodolfo de la Colina, the highest-ranking Argentine officer to die in the war. Stanley was used as an Argentine strongpoint throughout the conflict. Despite the Black Buck and Harrier raids on Stanley airfield (no fast jets were stationed there for air defence) and overnight shelling by detached ships, it was never out of action entirely. Stanley was defended by
18522-488: The submarine HMS Superb left Gibraltar and it was assumed in the press she was heading south. There has since been speculation that the effect of those reports was to panic the Argentine junta into invading the Falklands before submarines could be deployed; however, post-war research has established that the final decision to proceed was made at a junta meeting in Buenos Aires on 23 March. The following day, during
18669-419: The submarine, scoring hits. Santa Fe was damaged badly enough to prevent her from diving. The crew abandoned the submarine at the jetty at King Edward Point on South Georgia. With Tidespring now far out to sea and the Argentine forces augmented by the submarine's crew, Major Sheridan decided to gather the 76 men he had and make a direct assault that day. After a short forced march by the British troops and
18816-534: The subtropics to the northeastern Atlantic. There this water is cooled during winter and forms return currents that merge along the eastern continental slope of Greenland where they form an intense (40–50 Sv ) current which flows around the continental margins of the Labrador Sea . A third of this water becomes part of the deep portion of the North Atlantic Deep Water (NADW). The NADW, in turn, feeds
18963-508: The successful outcome, was re-elected with an increased majority the following year . The cultural and political effect of the conflict has been less in the UK than in Argentina, where it has remained a common topic for discussion. Diplomatic relations between the United Kingdom and Argentina were restored in 1989 following a meeting in Madrid , at which the two governments issued a joint statement. No change in either country's position regarding
19110-421: The surface is usually covered with sea ice in the Labrador Sea , Denmark Strait , and Baltic Sea. The Coriolis effect circulates North Atlantic water in a clockwise direction, whereas South Atlantic water circulates counter-clockwise. The south tides in the Atlantic Ocean are semi-diurnal; that is, two high tides occur every 24 lunar hours. In latitudes above 40° North some east–west oscillation, known as
19257-428: The total volume of the Earth's oceans. Excluding its marginal seas, the Atlantic covers 81,760,000 km (31,570,000 sq mi) and has a volume of 305,811,900 km (73,368,200 cu mi). The North Atlantic covers 41,490,000 km (16,020,000 sq mi) (11.5%) and the South Atlantic 40,270,000 km (15,550,000 sq mi) (11.1%). The average depth is 3,646 m (11,962 ft) and
19404-558: The upper layers of the circumpolar region, near the Drake Passage and the Falkland Islands. Both these currents receive some contribution from the Indian Ocean. On the African east coast, the small cyclonic Angola Gyre lies embedded in the large subtropical gyre. The southern subtropical gyre is partly masked by a wind-induced Ekman layer . The residence time of the gyre is 4.4–8.5 years. North Atlantic Deep Water flows southward below
19551-424: The western Atlantic and South Sandwich Trench (8,264 m or 27,113 ft) in the South Atlantic. There are numerous submarine canyons off northeastern North America, western Europe, and northwestern Africa. Some of these canyons extend along the continental rises and farther into the abyssal plains as deep-sea channels. In 1922, a historic moment in cartography and oceanography occurred. The USS Stewart used
19698-525: The winter months (April–November). The terrain is mountainous, with a central ridge and many fjords and bays along the coast. South Georgia is a breeding ground for elephant seals , fur seals , and king penguins . The island is home to the South Georgia pintail and the South Georgia pipit , which are endemic to the island. There are 25 native vascular plants on South Georgia , and 76 non-native species have been recorded. The island's topography includes
19845-597: The wounded up until the end of the conflict. The only Argentine Hercules shot down by the British was lost on 1 June when TC-63 was intercepted by a Sea Harrier in daylight as it was searching for the British fleet north-east of the islands, after the Argentine Navy retired its last SP-2H Neptune due to unreliability. Various options to attack the home base of the five Argentine Étendards at Río Grande were examined and discounted ( Operation Mikado ); subsequently five Royal Navy submarines were lined up, submerged, on
19992-528: Was adopted by 10 to 1 (with Panama voting against) and 4 abstentions. Significantly, the Soviet Union and China both abstained. The resolution stated: Deeply disturbed at reports of an invasion on 2 April 1982 by armed forces of Argentina; Determining that there exists a breach of the peace in the region of the Falkland Islands (Islas Malvinas), Demands an immediate cessation of hostilities; Demands an immediate withdrawal of all Argentine forces from
20139-485: Was applied to the southern Atlantic as late as the mid-19th century. During the Age of Discovery , the Atlantic was also known to English cartographers as the Great Western Ocean . The pond is a term often used by British and American speakers in reference to the northern Atlantic Ocean, as a form of meiosis , or ironic understatement. It is used mostly when referring to events or circumstances "on this side of
20286-693: Was aware of the Argentine carrier group approaching from the other direction and ordered the cruiser to be attacked to avoid being caught in a pincer movement ; he was unaware that the Veinticinco de Mayo had failed to gain enough headwind to launch her aircraft. The order to sink the cruiser was confirmed by the War Cabinet in London and the General Belgrano was hit by two torpedoes at 4 pm local time on 2 May, sinking an hour later. 321 members of General Belgrano ' s crew, along with two civilians on board
20433-469: Was cancelled at the last minute. On 30 April, the Reagan administration announced that they would be publicly supporting the United Kingdom. The nuclear-powered submarine Conqueror set sail from Faslane, Scotland on 4 April. The two aircraft carriers Invincible and Hermes and their escort vessels left Portsmouth , England only a day later. On its return to Southampton from a world cruise on 7 April,
20580-529: Was centred around the aircraft carrier ARA Veinticinco de Mayo with two old but missile-armed destroyers, and a second comprised three modern frigates. Both these groups were intended to approach the TEZ from the north. A third group approaching from the south was led by the Second World War -vintage Argentine light cruiser ARA General Belgrano ; although old, her large guns and heavy armour made her
20727-570: Was initially taken by surprise by the Argentine attack on the South Atlantic islands, despite repeated warnings by Royal Navy captain Nicholas Barker (Commanding Officer of the Endurance ) and others. Barker believed that Defence Secretary John Nott 's 1981 Defence White Paper (in which Nott described plans to withdraw the Endurance , the UK's only naval presence in the South Atlantic) had sent
20874-531: Was intercepted by British Harriers who visually identified the civilian plane. The South Georgia force, Operation Paraquet , under the command of Major Guy Sheridan RM, consisted of Marines from 42 Commando , a troop of the Special Air Service (SAS) and Special Boat Service (SBS) troops who were intended to land as reconnaissance forces for an invasion by the Royal Marines, a total of 240 men. All were embarked on RFA Tidespring . First to arrive
21021-467: Was probably discovered in 1675 by Anthony de la Roché , a London merchant, and was named Roche Island on a number of early maps. It was sighted by a commercial Spanish ship named León operating out of Saint-Malo on 28 or 29 June 1756. According to Argentine historians, it was explored on 29 June 1756, St Peter's Day , hence its Spanish name Isla San Pedro , literally "St Peter's Island". The mariner Captain James Cook in HMS Resolution made
21168-456: Was sent on 1 May, in the belief that the British invasion was imminent or landings had already taken place. Only a section of Grupo 6 (flying IAI Dagger aircraft) found ships, which were firing at Argentine defences near the islands. The Daggers managed to attack the ships and return safely. This greatly boosted the morale of the Argentine pilots, who now knew they could survive an attack against modern warships, protected by radar ground clutter from
21315-466: Was shot down by an AIM-9L Sidewinder air-to-air missile (AAM), while the other escaped but was damaged and without enough fuel to return to its mainland airbase. The plane made for Stanley, where it fell victim to friendly fire from the Argentine defenders. As a result of this experience, Argentine Air Force staff decided to employ A-4 Skyhawks and Daggers only as strike units, the Canberras only during
21462-585: Was the Churchill -class submarine HMS Conqueror on 19 April, and the island was over-flown by a Handley Page Victor aircraft with radar-mapping equipment on 20 April, to establish that no Argentine ships were in the vicinity. The first landings of SAS and SBS troops took place on 21 April, but an ill-advised mission to establish an SAS observation post on the Fortuna Glacier had to be withdrawn after two helicopters crashed in fog and high winds. On 23 April,
21609-507: Was the main architect and supporter of a military solution for the long-standing claim over the islands, expecting that the United Kingdom would never respond militarily. By opting for military action, the Galtieri government hoped to mobilise the long-standing patriotic feelings of Argentines towards the islands, diverting public attention from the chronic economic problems and the ongoing human rights violations of its Dirty War , bolstering
