The nuclear-powered submarine set sail from Faslane, Scotland on 4 April. The two aircraft carriers and and their escort vessels left
Portsmouth, England only a day later. The retaking of the Falkland Islands was considered extremely difficult. The chances of a British counter-invasion succeeding were assessed by the
US Navy, according to the historian
Arthur L. Herman, as "a military impossibility". Firstly, the British were significantly constrained by the disparity in deployable air cover. The British had 42 aircraft (28
Sea Harriers and 6
Harrier GR.3s) available for air combat operations, against approximately 122 serviceable jet fighters, of which about 50 were used as
air superiority fighters and the remainder as
strike aircraft, in
Argentina's air forces during the war. By mid-April the
Royal Air Force had set up an airbase on
RAF Ascension Island, co-located with Wideawake Airfield, on 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; the British Task Force was shadowed by a
Boeing 707 aircraft of the
Argentine Air Force during their travel to the south. Several of these flights were intercepted by Sea Harriers outside the British-imposed
Total Exclusion Zone; the unarmed 707s were not attacked because diplomatic moves were still in progress and the UK had not yet decided to commit itself to armed force. On 23 April, a Brazilian commercial
Douglas DC-10 from
VARIG Airlines en route to South Africa was intercepted by British Harriers who visually identified the civilian plane.
Recapture of South Georgia and the attack on Santa Fe 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 . First to arrive was the 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 a submarine alert was sounded and operations were halted, with
Tidespring being withdrawn to deeper water to avoid interception. On 24 April British forces regrouped and headed in to attack. On 25 April, after resupplying the Argentine garrison in South Georgia, the submarine was spotted on the surface by a
Westland Wessex HAS Mk 3 helicopter from , which attacked the Argentine submarine with
depth charges. launched a
Westland Wasp HAS.Mk.1 helicopter, and launched a
Westland Lynx HAS Mk 2. The Lynx launched a
torpedo, and
strafed the submarine with its
pintle-mounted
general purpose machine gun; the Wessex also fired on
Santa Fe with its
GPMG. The Wasp from as well as two other Wasps launched from fired
AS-12 ASM antiship missiles at 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 a naval bombardment demonstration by two Royal Navy vessels (
Antrim and
Plymouth), the Argentine forces, a total of 190 men, surrendered without resistance to the Royal Marines. The message sent from the naval force at South Georgia to London was, "Be pleased to inform Her Majesty that the
White Ensign flies alongside the
Union Jack in South Georgia. God Save the Queen." The Prime Minister, Margaret Thatcher, broke the news to the media, telling them to
"Just rejoice at that news, and congratulate our forces and the Marines!" Black Buck raids Avro Vulcan B.Mk.2
strategic bomber 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 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 the raids on the war is difficult to determine; 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 the small Sea Harrier force, the raids were costly and used a great deal of resources. The runway was cratered by only one of the twenty one bombs, with the single hit to the edge of the runway 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 the capital. Some sources have claimed that, as a result of the raid, the Argentines realised that their mainland was vulnerable and fighter aircraft were redeployed from the theatre to bases further north, but later Argentine sources confirm that the Vulcan raids did not influence Argentina's decision to move some of its Mirage IIIs from southern Argentina to the Buenos Aires Defence Zone. This dissuasive effect was watered down when British officials made clear that there would not be strikes on air bases in Argentina. The raids were later dismissed as propaganda by Falklands veteran Commander Nigel Ward. Of the five Black Buck raids, three were against Stanley Airfield, with the other two being anti-radar missions using
Shrike anti-radiation missiles.
Escalation of the air war of the
Argentine Naval Aviation 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 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. on 19 May 1982 The first major Argentine strike force comprised 36 aircraft (
A-4 Skyhawks,
IAI Daggers,
English Electric Canberras, and
Mirage III escorts), and was sent on 1 May, in the belief that the British Liberation 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 the islands and by using a late
pop up profile. Meanwhile, other Argentine aircraft were intercepted by
BAE Sea Harriers operating from . 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 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 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 35A was shot down by HMS
Exeter, killing the squadron commander, Vice Commodore Rodolfo de la Colina, the highest-ranking Argentine officer to die in the war. British command was concerned about the high attrition of Harriers brought down by anti-air, and committed to use them predominately for air superiority. The Harriers were observed to be far more effective than ship-launched missiles to destroy attacking Argentine aircraft, however at times the operations of Harriers in the air would interfere with a vessel's anti-air systems. 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 a mixture of
surface-to-air missile (SAM) systems (Franco-German
Roland and British
Tigercat) and light anti-aircraft guns, including Swiss-built
Oerlikon 35 mm twin cannons and
30 mm Hispano-Suiza cannon and German
Rheinmetall 20 mm twin anti-aircraft cannons. 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 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 the edge of Argentina's 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 the Falklands; however the Canberras had reached
Belize when the operation was abandoned after part of the plan had been reported in the British press. Operation Acme was the deployment of a single Nimrod R.1 surveillance aircraft of
No. 51 Squadron RAF to the Chilean base at
Isla San Félix to gather
signals intelligence from Argentinian forces in the Falklands; three sorties were conducted, 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 the Task Force by means of Operation Shutter, a US supplied SATCOM system installed at the Chilean Air Force headquarters in
Santiago and operated by two soldiers of the
Royal Corps of Signals.
Sinking of ARA General Belgrano On 30 April the British government had brought into force a Total Exclusion Zone (TEZ) to replace the previous Maritime Exclusion Zone; aircraft as well as ships of any nation were liable to be attacked inside it, if they were aiding the Argentine occupation. Admiral
Sandy Woodward's carrier battle group of twelve warships and three supply ships entered the TEZ on 1 May, shortly before the first Black Buck raid, intending to degrade Argentine air and sea forces before the arrival of the amphibious group two weeks later. In anticipation, Admiral Anaya had deployed all his available warships into three task groups. The first was centred around the aircraft carrier 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 ; although old, her large guns and heavy armour made her a serious threat. On 1 May the British nuclear-powered submarine (one of three patrolling the TEZ) located the
General Belgrano group and followed it until the following day, when it was about 12 hours away from the Task Force and just outside the Total Exclusion Zone. Admiral Woodward 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
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
General Belgrano was hit by two torpedoes at 4 pm local time on 2 May, sinking an hour later. 321 members of
General Belgranos crew, along with two civilians on board 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. The sinking 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 , The sinking generated
significant controversy, 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. However, in 2003 the ship's captain, Hector Bonzo, stated to a documentary crew that
General Belgrano had been manoeuvring, not sailing away from the exclusion zone, and that he had orders to sink any British ship he could find. In a separate incident later that night, British forces engaged an Argentine patrol gunboat, the , that was searching for the crew of an Argentine Air Force
Canberra light bomber shot down on 1 May. Two Royal Navy
Lynx helicopters, from and , fired four
Sea Skua missiles at her. Badly damaged and with eight crew dead,
Alferez Sobral managed to return to
Puerto Deseado two days later. The Canberra's crew were never found.
Sinking of HMS Sheffield On 4 May, two days after the sinking of
General Belgrano, the British lost the
Type 42 destroyer to fire following an
Exocet missile strike from the Argentine
2nd Naval Air Fighter/Attack Squadron.
Sheffield had been ordered forward with two other Type 42s to provide a long-range radar and medium-high altitude missile
picket far from the British carriers. She was struck amidships, with devastating effect, ultimately killing 20 crew members and severely injuring 24 others. The ship was abandoned several hours later, gutted and deformed by fires. For four days she was kept afloat for inspections and the hope that she might attract Argentine submarines which could be hunted by helicopter. The decision was then taken to tow her to Ascension, but while under tow by , she finally sank east of the Falklands on 10 May. The incident is described in detail by Admiral Woodward in his book
One Hundred Days, in Chapter One. Woodward was a former commanding officer of
Sheffield. The destruction of
Sheffield, the first Royal Navy ship sunk in action since the Second World War, had a profound impact on the War Cabinet and the British public as a whole, bringing home the fact that the conflict was now an actual shooting war.
Diplomatic activity The tempo of operations increased throughout the first half of May as the United Nations' attempts to mediate a peace were rejected by the Argentines. The final British negotiating position was presented to Argentina by UN Secretary-General
Javier Pérez de Cuéllar on 18 May 1982. In it, the British abandoned their previous "red-line" that British administration of the islands should be restored on the withdrawal of Argentine forces, as supported by
United Nations Security Council Resolution 502. Instead, it proposed a UN administrator should supervise the mutual withdrawal of both Argentine and British forces, then govern the islands in consultation with the representative institutions of the islands, including Argentines, although no Argentines lived there. Reference to "
self-determination" of the islanders was dropped and the British proposed that future negotiations over the sovereignty of the islands should be conducted by the UN. However, the proposals were rejected by the Argentines on the same day.
Special forces operations Given the threat to the British fleet posed by the Étendard-Exocet combination, plans were made to use C-130s to fly in
SAS troops to attack the home base of the five Étendards at
Río Grande, Tierra del Fuego. The operation was codenamed "
Mikado". The operation was later scrapped, after acknowledging that its chances of success were limited, and replaced with a plan to use the submarine to drop SBS marines several miles offshore at night for them to make their way to the coast aboard rubber inflatables and proceed to destroy Argentina's remaining Exocet stockpile – which did not exist at their objective. An SAS reconnaissance team was dispatched to carry out preparations for a seaborne infiltration. A
Westland Sea King helicopter carrying the assigned team took off from HMS
Invincible on the night of 17 May, but bad weather forced it to land from its target and the mission was aborted. The pilot flew to
Chile, landed south of
Punta Arenas, and dropped off the SAS team. The helicopter's crew of three then destroyed the aircraft, surrendered to Chilean police on 25 May, and were repatriated to the UK after interrogation. The discovery of the burnt-out helicopter attracted considerable international attention. Meanwhile, the SAS team crossed the border and penetrated into Argentina, but cancelled their mission after the Argentines suspected an SAS operation and deployed some troops to search for them. The SAS men were able to return to Chile and took a civilian flight back to the UK. On 14 May the SAS carried out a
raid on Pebble Island on the Falklands, where the Argentine Navy had taken over a grass airstrip map for
FMA IA 58 Pucará light ground-attack aircraft and
Beechcraft T-34 Mentors, which resulted in the destruction of several aircraft. On 15 May, SBS teams were inserted by HMS
Brilliant at
Grantham Sound to reconnoitre and observe the landing beaches at
San Carlos Bay. On the evening of 20 May, the day before the main landings, an SBS troop and artillery observers were landed by Wessex helicopters for an assault on an Argentine observation post at Fanning Head which overlooked the entrance of the bay; meanwhile, the SAS conducted a diversionary raid at
Darwin. == Air attacks ==
