Operation Georgias was the codename used by the Argentine Armed Forces for the operation to occupy the South Georgia Islands at the start of the Malvinas/Falklands War in 1982.
The invasion of South Georgia took place on 3 April 1982, when Argentine naval forces took control of South Georgia Island (renamed Isla San Pedro) after forcing the surrender of a small contingent of British Royal Marines in Grytviken. The Argentine intervention began on 19 March 1982, when a group of civilian workers arrived at Leith Harbour aboard the transport vessel ARA Bahía Buen Suceso (B-4), raising the Argentine flag. Some Argentine marines had infiltrated the group, posing as civilian scientists.

Argentine Workers in South Georgia

The Davidoff Contracts

In September 1979, Argentine businessman Constantino Davidoff, director of the company Georgia del Sur S.A. and a scrap metal dealer, signed a contract with the Edinburgh-based firm Christian Salvesen Co. The agreement granted him the right to remove the remains of the abandoned whaling stations at Leith, Stromness, and Husvik on the South Georgia Islands.
Davidoff approached the British Embassy in Buenos Aires requesting the use of the polar ship HMS Endurance to transport personnel and equipment necessary for dismantling the facilities. When the British authorities refused permission to use HMS Endurance, in August 1981 Davidoff sought approval from the Argentine Ministry of Foreign Affairs and the Navy to book passage aboard Antarctic transport vessels.
Aware of the British government's decision to withdraw HMS Endurance from service in the South Atlantic and anticipating a possible evacuation of Grytviken, the Argentine Navy signed an agreement with Davidoff that allowed him to travel to the islands at least twice a year.

Project and Operation Alfa

In September 1981, the Argentine Navy developed a plan to use Davidoff's salvage operations in South Georgia as a cover for establishing a covert base in the disputed territory. This initiative was given the codename Project Alfa. The plan involved infiltrating military personnel among the workers, posing as scientists. Once HMS Endurance had left the South Atlantic (from April onwards), they would be joined by 14 marines aboard a ship assigned to Antarctic base support, who would then establish a permanent military outpost on South Georgia. The base would benefit from the onset of winter, which would hinder any British attempt to remove it.

Parallel to this project, in October 1981, the commander of Antarctic naval operations received an order from the Chief of Operations of the Navy General Staff to study the possibility of establishing a scientific base on one of the disputed islands with the United Kingdom. It was expected that the base would be set up during the 1981–1982 Antarctic campaign. This operation was designated Operation Alfa.
In early December, a decision was made that the base would be manned by military personnel rather than civilians, due to the need for secrecy. The Amphibious Commando Group was ordered to assign 1 officer and 6 NCOs. The same instruction applied to an equal number of tactical divers.

On 29 January 1981, training began for the selected commandos and divers, under the command of Lieutenant Alfredo Astiz. The team included Lieutenant Carrilaff, 1 diver NCO, 1 medic NCO, 5 diver corporals, and 5 amphibious commando corporals. On 28 February, they boarded the Antarctic campaign vessel ARA Bahía Paraíso in Ushuaia.
To avoid interfering with planned operations in the Malvinas, the Military Committee cancelled Operation Alfa on 16 March. However, the commandos remained onboard as a precaution and departed on 18 March towards the South Orkney Islands, accompanying the vessel’s Antarctic campaign.



ARA Almirante Irízar

Davidoff’s Journeys

The Argentine businessman informed the British Embassy of his trip but did not request permission to travel aboard the icebreaker. On 16 December 1981, he set sail for South Georgia aboard the icebreaker ARA Almirante Irízar (Q-5) to carry out an inventory of the facilities to be dismantled at Stromness Bay. He arrived there on the 21st and departed a few days later.
On 23 December, the British magistrate in South Georgia discovered evidence of Argentine presence at Leith Harbour and reported it to Rex Hunt, Governor of the Falkland/Malvinas Islands, who relayed the information to London on 31 December. The British government instructed its embassy to issue a formal note of protest against the unauthorised landing, considered a breach of sovereignty. However, Argentina’s Foreign Minister claimed ignorance of the incident. A second formal protest was issued on 9 February but was rejected by the Argentine Foreign Ministry on 18 February.

Another Argentine trip to the islands occurred in February 1982, when a commercial rival of Davidoff, bank employee Adrián Marchessi, made an unplanned visit to Leith Harbour. Marchessi arrived at the site aboard the Caimán, a yacht registered in Panama, having sailed from Mar del Plata. He reported in at Grytviken, claiming to be part of Davidoff’s team, and provided the local British authorities with details of Davidoff’s December inspection as well as information on previous Argentine visits to the area during the 1970s.

Raising of the Argentine Flag

On 18 March 1982, the transport ship ARA Bahía Buen Suceso arrived at Leith Harbour, disembarking Davidoff’s workers and their equipment without first reporting at Grytviken, as required by the British government. At that time, the only British presence at Leith Harbour was a team from the British Antarctic Survey (BAS).
On 19 March, four BAS members en route to Carlita Bay discovered the ARA Bahía Buen Suceso unloading equipment at Leith Harbour, with the Argentine flag flying. Around 100 people had disembarked and occupied a BAS shelter. The BAS team leader, Trevor Edwards, approached Captain Briatore to inform him that their presence was unauthorised and that they were required to report at Grytviken. Edwards then informed the British magistrate at King Edward Point.
The BAS commander in Grytviken, Steve Martin, sent a message to Governor Rex Hunt, who consulted with London. The British authorities demanded the removal of the Argentine flag and the re-embarkation of the workers. Captain Briatore responded that the mission had the approval of the British Embassy in Buenos Aires and ordered the flag lowered, but he still did not comply with the order to report at Grytviken.

On 20 March, British Prime Minister Margaret Thatcher was informed of the events. As the Argentines had failed to follow proper diplomatic procedures, the British government decided to respond with a limited intervention. The Foreign Office ordered HMS Endurance to sail to the area to ensure the removal of the Argentine flag and prevent any further landings. The ship had departed from Port Stanley on 16 March, carrying 22 Royal Marines.
On 21 March, the British Embassy in Buenos Aires issued a diplomatic protest, requesting that the Argentine government withdraw the workers.
Argentina’s Foreign Minister, Nicanor Costa Méndez, responded by appearing to de-escalate the crisis, assuring that the ARA Bahía Buen Suceso would soon depart the islands and that the incident had no official backing.

On the morning of 22 March, the ARA Bahía Buen Suceso left Leith Harbour. However, later that day, a BAS observation post detected the continued presence of Argentine personnel and relayed the information to London. As a result, the Foreign Office ordered HMS Endurance to evacuate any remaining Argentine personnel in South Georgia.



 

Operation Georgias

On 23 March, the Commander of the Antarctic Naval Group, Captain César Trombetta, aboard ARA Bahía Paraíso (B-1) and stationed in the South Orkney Islands, received orders from the Argentine Naval General Staff to proceed at full speed to the South Georgia Islands. His mission was to prevent HMS Endurance—which had departed from the Malvinas—from removing Davidoff’s Argentine workers from Leith Harbour.

In response to British movements, Argentina deployed several countermeasures. The corvettes ARA Drummond (P-31) and ARA Granville (P-33) were positioned between the Malvinas and South Georgia, ready to intercept HMS Endurance and recover any Argentine personnel on board.

On 24 March, the Argentine government publicly confirmed the presence of the workers on South Georgia. That same day, Lieutenant Alfredo Astiz received orders to “disembark at Leith Harbour at 00:15 on 25 March to protect the Argentine workers.”
That night, ARA Bahía Paraíso arrived at Leith and disembarked 14 armed military personnel (Group Alfa) under Astiz’s command, using weapons supplied by the ship. The vessel remained in the area, patrolling with its helicopters. News from the region reported unusual Argentine naval activity in the South Atlantic.

When HMS Endurance reached Leith Harbour, it found ARA Bahía Paraíso anchored there. The two ships then shadowed each other around the islands until they lost contact on 31 March.

In anticipation of a possible armed clash, the British Foreign Office attempted to negotiate a compromise. Lord Carrington proposed to Argentine Foreign Minister Costa Méndez that the workers at Leith Harbour be granted amnesty and provided with documentation—possibly temporary entry permits instead of passports, a significant concession to the Argentine position.
However, Argentina insisted that the arrival of its nationals in South Georgia should be governed by the 1971 Communications Agreement. Governor Rex Hunt strongly rejected extending that agreement—valid only for the Malvinas—to South Georgia and expressed his concerns to London.

The British plan was that BAS commander Steve Martin would remain in control until Argentine forces displayed hostile intent, at which point Lieutenant Keith Paul Mills would assume command.

On 28 March 1982, at 10:57, the destroyer ARA Santísima Trinidad (D-2) set sail as flagship of Task Force 40, carrying both the Task Force Commander and the Malvinas Theatre Commander, Major General Osvaldo García. This marked the beginning of Operation Rosario, which would lead to the surrender of the British governor in the Malvinas on 2 April.

That same day, 40 marines under Lieutenant Guillermo Luna boarded the corvette ARA Guerrico (P-2, now P-32) at Puerto Belgrano, bound for South Georgia. The journey was harsh and overcrowded, as the vessel was not suited for troop transport and faced poor weather during the four-day voyage.

On 30 March, with the invasion clearly imminent, the British government ordered the destroyer HMS Antrim, followed by two other surface vessels and three nuclear submarines, to proceed to South Georgia to reinforce HMS Endurance. The rest of the Royal Navy was placed on four-hour alert.

On 1 April, the Argentine Naval General Staff issued Operational Order No. 1/82 “S”, instructing forces to “occupy Grytviken and hold Leith to secure control of the South Georgia Islands.”
Missile corvette ARA Guerrico, under Commander Carlos Alfonso, was ordered to rendezvous with ARA Bahía Paraíso, which was equipped with two helicopters (a Puma from the Argentine Army and an Alouette from the Navy Air Command). The 40 marines under Luna’s command joined Astiz’s troops already stationed at Leith.

Up to that date, South Georgia had not been included in the Malvinas Theatre of Operations.

With the available units, Task Group 60.1 was formed under the command of Captain César Trombetta. The group was composed of the following elements:[22]

  • 60.1.1. Polar ship ARA Bahía Paraíso, commanded by Frigate Captain Ismael J. García

  • 60.1.2. Corvette ARA Guerrico, commanded by Frigate Captain Carlos Alfonso

  • 60.1.3. A detachment from Marine Infantry Battalion No. 4 (BIM 4), consisting of 40 marines under the command of Lieutenant Guillermo Luna

  • 60.1.4. Two helicopters from the Antarctic Group: one Puma (Argentine Army) and one Alouette (Naval Aviation Command of the Argentine Navy)

  • 60.1.5. A group of tactical divers and amphibious commandos (14 men), commanded by Lieutenant Alfredo Astiz

In response to these developments, a series of high-level meetings and diplomatic discussions took place in an attempt to prevent an Argentine invasion. On the night of 1 April, U.S. President Ronald Reagan pledged to British Prime Minister Margaret Thatcher that he would speak directly with the Argentine Junta to avert an attack.

However, Reagan's phone conversation with Leopoldo Galtieri proved unsuccessful.[23]

British Resistance

2 April

On 2 April, Lieutenant Alfredo Astiz informed the Argentine personnel at Leith Harbour that Argentina had recovered the Malvinas, and he received the order to execute Operational Order No. 1/82 “S”.

Upon learning of the fall of Puerto Argentino (Port Stanley), British Lieutenant Keith Paul Mills acted quickly. His men fortified the beach at King Edward Point, near the entrance to the bay, using barbed wire and landmines, and set up defensive positions around the British Antarctic Survey (BAS) buildings. HMS Endurance, positioned a few miles offshore, maintained communications between the small British detachment and London. Mills was authorised to open fire in self-defence after issuing a warning. A subsequent statement from the British government instructed the Royal Marines “not to resist beyond the point where lives would be needlessly lost.”[24]

Due to severe weather, the ARA Guerrico only entered Cumberland Bay at 17:00 on 2 April. As a result, Argentina’s planned operations in South Georgia had to be postponed by Commander César Trombetta to the following day. The original plan had called for Astiz’s special forces to land at Hope Point, near Grytviken, to secure the arrival zone for the main ground troops, who would be flown in by helicopter. ARA Guerrico was to provide naval gunfire support from outside the bay, but her delayed arrival due to the storm forced a revised plan for 3 April.

Under the new plan:

  • The first landing would be carried out by an Alouette helicopter from ARA Guerrico.

  • This would be followed by three waves of marine infantry aboard a Puma helicopter from ARA Bahía Paraíso.

  • A radio message demanding British surrender would be sent before any landing.

  • After the warning, ARA Guerrico would move toward Caleta Capitán Vago (where Grytviken’s port is located), opposite King Edward Point.

The corvette was only authorised to fire upon request from the ground forces. Astiz’s troops were to remain in reserve aboard Bahía Paraíso, and all units were instructed to avoid enemy casualties as long as possible.[25]

Historian Lawrence Freedman believes that Trombetta’s assumption of minimal resistance was based on the belief that only BAS personnel were present. This was apparently due to the absence of HMS Endurance, which led Trombetta to underestimate the British military presence.
Trombetta ordered ARA Guerrico to approach the shore, dispatch the Alouette for reconnaissance, and use the Puma to transport the first marine detachment.[26]

During the night, both Argentine ships made contact and remained in nearby waters, with ARA Guerrico anchored in Stromness Bay.

3 April

At 05:00 on 3 April, Lieutenant Guillermo Luna received a naval message indicating that HMS Endurance was in Grytviken with 22 Royal Marines. However, Commander Trombetta believed that the landing zone would be clear, with any British personnel remaining aboard the polar ship.

At 07:35, with improved weather, ARA Guerrico arrived at Leith Harbour, where it transferred the marines to ARA Bahía Paraíso. Astiz’s commandos were re-embarked, and the workers left ashore under protection of forces from Bahía Paraíso, led by Lieutenant Cortez.

At 11:10, a surrender demand was transmitted from ARA Bahía Paraíso in English, and repeated three minutes later. The message falsely claimed that Governor Rex Hunt had surrendered not only in the Malvinas but also in all dependencies, including South Georgia.[13]
Lieutenant Mills received the message and relayed it to HMS Endurance to buy time. He also advised BAS personnel to take shelter in the local church. The British soldiers refused to surrender.

Meanwhile, the Alouette helicopter was flying over Grytviken, reporting no signs of visible resistance. ARA Guerrico began entering the inlet.
According to Argentine Admiral Rubén Oscar Mayorga, the corvette’s commander, Captain Carlos Alfonso, hesitated to bring the ship into such confined waters. Mayorga supports Freedman’s view that Trombetta’s assumptions about British military presence were incorrect. He cites an official report indicating that Trombetta underestimated the situation, also expressing concerns about ARA Guerrico’s readiness for combat.[28] The ship had only recently returned to active service after being in dry dock until just days before departing from Puerto Belgrano.[29]

At 11:25, the Argentine command ordered the personnel at Grytviken to move into the open, announcing that a landing by marine infantry would take place. Ten minutes later, the ARA Guerrico reported the presence of armed personnel on the ground.

At 11:41, the first wave of 15 Argentine marines, including Lieutenant Luna, was deployed by a Puma helicopter at King Edward Point, opposite Shackleton House, where the British Royal Marines were entrenched. By then, the crew aboard Guerrico had confirmed that the British were positioned along the northern shore of the inlet.

A second wave of marines departed ARA Bahía Paraíso at 11:47, on the Puma, carrying Lieutenant Giusti, 14 marines, and a machine gun. However, Lieutenant Luna, already on the ground, had requested via Guerrico—as he had no direct communication with Bahía Paraíso—that the second wave be delayed and replaced with a third group carrying 60mm mortars. But the second wave was already airborne.

The landing took place east of Luna's position and in full view of the British defenders. The Puma came within effective range of British automatic weapons. It was immediately hit by heavy fire, but the pilot managed to cross the bay and conduct an emergency landing on the southern shore, opposite King Edward Point (known in Argentina as Punta Coronel Zelaya).

Two Argentine conscripts, Mario Almonacid and Jorge Néstor Águila, were killed. Four others were wounded, and the rest were left disorganised and out of combat position. Despite the setback, the marines opened fire with their machine gun on the hospital building, wounding one British marine in the arm.

At the same time, Luna’s troops began to advance toward Shackleton House, but after the Puma was downed, the British responded with heavy fire.[13] In response, Luna requested fire support from ARA Guerrico.

Attack on ARA Guerrico

At 11:55, Guerrico began its second approach to the inlet and opened fire. However, her 20mm guns jammed after the first shot. The 40mm cannons managed only six bursts, and the 100mm main gun became inoperable after a single round. Now fully exposed, the corvette had no choice but to turn within the cove and fire with weapons mounted on the opposite side.

At 11:59, British forces opened fire on the ship. The corvette was struck by small arms and a Carl Gustav 84mm anti-tank rocket launcher.[31] According to Mills, his men fired from a distance of approximately 550 metres.

The attack killed Petty Officer Patricio Guanca, wounded five sailors, and damaged multiple systems: electrical cables, one 40mm gun, an Exocet missile launcher, and the 100mm turret mount. As Guerrico passed again in front of the British position to retreat, she was hit by another intense wave of fire.
Argentine sources acknowledged that the vessel sustained over 200 hits during the engagement.[32]

Meanwhile, the Alouette helicopter—a reconnaissance aircraft—was used to transport the remaining 10 marines, landing them outside the range of British weapons.[13]

As the damaged Guerrico withdrew from the bay, the Argentine ground troops resumed small arms exchanges with Mills’ Royal Marines.[13] Once beyond the range of British weapons—near Hobart RockGuerrico resumed firing with her repaired 40mm guns.[33] This convinced Lieutenant Mills that the situation was untenable. He ordered his men to cease fire at 12:48, according to Admiral Mayorga.[33]

At 13:00, Mills approached the Argentine lines waving a white flag and surrendered. He was instructed to have his men surrender one by one. Mills and his marines were taken into custody by Astiz’s group, which had remained in reserve during the battle.[13]
At 13:35, the British flag was reported lowered.

HMS Endurance dispatched one of its Wasp helicopters to Cumberland Bay. The aircraft detected the Argentine corvette and the transport vessel in the cove but observed no signs of combat. HMS Endurance remained in South Georgia waters until 5 April.[34]

That afternoon, 13 BAS civilian personnel who had been scattered in the surrounding area were captured. At 23:00, Group Alfa replaced Lieutenant Cortez and his men in securing the workers at Leith Harbour.




ARA Guerrico

Consequences

Following the engagement at Grytviken, the corvette ARA Guerrico, which had lost approximately 50% of its firepower due to battle damage, departed Grytviken alongside ARA Bahía Paraíso at 03:15 on 4 April, bound for Río Grande.[35]

The ARA Bahía Paraíso transported the captured British Royal Marines to Río Grande, from where they were flown to Montevideo. They returned to the United Kingdom on 20 April.[13]

The Argentine forces chose not to attack the BAS station on Bird Island, where 15 British BAS personnel remained out of Argentine control. These individuals also remained active in other areas such as Schlieper Bay, the Lyell Glacier, and Saint Andrews Bay, avoiding capture until the islands were retaken by British forces.

The Argentine Navy left behind a garrison of 55 marines on the islands, along with 39 civilian scrap workers who remained stationed at Leith Harbour.[34]

The South Georgia Islands were retaken by British forces on 25 April 1982 during Operation Paraquat.[36]

Medals

  • Lieutenant Keith Paul Mills was awarded the Distinguished Service Cross (DSC).

  • Captain Nick Barker of HMS Endurance received the title of Commander of the Order of the British Empire (CBE).[13]

  • Chief Gunner Francisco Solano Páez was awarded the Argentine Medal for Valour in Combat (La Nación Argentina al Valor en Combate).[37]
