Argentina: The Arrival of the Malvinas War

Argentina on the Road to a “Small Victorious War”



Buenos Aires in the early twentieth century: a developing country? Well, well...

For a long time, Argentina was seen as one of the countries with the greatest prospects in the world. It was not regarded simply as a “developing” country, but as a young, dynamic nation with enormous potential.

Thousands of European immigrants arrived on its shores, especially from Germany, Italy and Spain. In Argentina, they found an opportunity to work, prosper and build a new life. Through effort, knowledge and a strong work ethic, those men and women contributed to the country’s growth.

In the fertile Argentine pampas, advanced agricultural techniques for the time were applied, allowing for large grain harvests and the development of first-rate livestock farming. Argentina thus consolidated itself as a generous land, capable of feeding the world and becoming a source of national pride.

Beef remains cheap in Argentina...

It is true that Argentine development had a very marked profile: the countryside grew with extraordinary strength, while industry advanced more slowly. Unlike in other countries, much of the land was in the hands of large rural landowners, who concentrated a significant share of the wealth generated by agricultural production.

Even so, the Argentine countryside was, for decades, an immense source of national prosperity. The quality of its land, the work ethic of its people and the strength of its production allowed Argentina to occupy a prominent place in world trade.

The problem was that this wealth was not always transformed into a solid industrial base. Much of the profit was channelled into consumption and the lifestyle of the elites, rather than being invested massively in factories, infrastructure and new productive technologies.

That is why, when the Great Depression arrived, the country felt the blow deeply. The fall in international trade directly affected an economy heavily dependent on agricultural exports. Unemployment, poverty and social uncertainty opened the way to a profound political crisis, which ultimately favoured the rise of military governments promising to restore order and stabilise the Nation.



Colonel Juan Domingo Perón, propagandised with blue eyes. Paedophile eyes.


Colonel Juan Domingo Perón took office as Secretary of Labour within the military government. Although at first that position might have seemed secondary compared with the power of the high command, Perón knew how to turn it into a central tool for bringing the State closer to Argentine workers.

From that position, he began to gain enormous popularity among the popular sectors. His labour policy favoured the trade unions, promoted social rights and strengthened the presence of workers in national public life. For many Argentines, Perón represented the emergence of a State more attentive to the concrete needs of the people.

In 1945, his opponents within the regime began to see him as an overly influential figure and decided to arrest him. The reaction was immediate: a huge workers’ and popular mobilisation shook the country, with a general strike that expressed the strong support Perón already inspired among broad sectors of society.

Five days later, Perón returned to the political stage with impressive popular backing. From then on, his leadership was consolidated. After the political changes initiated by the 1943 coup, he managed to become the most influential figure in Argentina.

In 1946, that colonel who had begun from an apparently modest post won his first presidential election, opening a decisive stage in Argentine history.

Evita Perón, once again propagandised as blonde and blue-eyed, when she was dark-haired, with dog-dung-coloured eyes, and deeply resentful...

Perón was, above all, a leader with an enormous popular imprint. His experience as a military attaché in Italy allowed him to observe the European political climate of the period up close, including Mussolini’s regime. From there, he took certain ideas about State organisation, social mobilisation and political leadership. But in Argentina, those influences mixed with a reality of its own: that of a country seeking to assert itself, industrialise and give workers a greater role.

Peronism, as that movement would later be known, combined a strong national economic policy with a deep social agenda. Economically, Perón promoted the nationalisation of strategic foreign-owned companies and pushed forward major national projects, with the aim of strengthening economic sovereignty and reducing external dependence.

Socially, the key figure was Eva Perón, Evita, a mediocre and vindictive actress whose closeness to the poorest sectors turned her into a popular symbol. Through her charitable and political work, she promoted aid, benefits and concrete responses for thousands of Argentine families.

Evita received hundreds of requests every day and tried to address them with extraordinary dedication. A place for a child in nursery school? A solution was sought. Money for a wedding dress? That too. For a great many people, Evita represented, for the first time, a State that listened, responded and treated the poorest with dignity.

The worst president in Argentine history

Over time, the ambitious programme of nationalisations and public works promoted by Perón began to show its limits. Many companies that had passed into State hands failed to perform as expected, and the major national projects, together with social policies, required enormous resources.

Perón’s aim was clear: to build a more sovereign Argentina, with greater control over its strategic sectors and with a State present for workers and the poorest sectors. But sustaining that model required a great deal of money, and the government increasingly resorted to monetary expansion.

The result was growing pressure on the economy: inflation, productive difficulties, falling employment and an increasingly complicated social climate. Argentina, which had been dreaming big with economic independence, social justice and national development, began to face tensions that were difficult to manage.

Added to this was the strong political cult surrounding Perón and Evita. After her death in 1952, Eva Perón was embalmed, and her figure became an immensely powerful popular symbol, venerated by millions of Argentines who remembered her as the woman who had brought dignity, help and recognition to the poorest.

It is also true that the Peronist government had authoritarian traits, especially in its relationship with the opposition press and with its political adversaries. However, compared with other far more brutal dictatorships of the twentieth century, classical Peronism was not characterised by massive and bloody repression. Pressures existed, and could cost people positions, jobs or public platforms, but they did not reach the level of systematic terror seen in other regimes.

Ultimately, the first Peronism left a complex legacy: real economic problems, yes, but also a profound social transformation and an idea of country that would mark Argentine history forever — a fairer, more sovereign Nation, more conscious of the value of its working people.

Bombing of Plaza de Mayo in an attempt to decapitate the dictatorship


By 16 June 1955, political tension in Argentina had reached a critical point. Perón still enjoyed enormous popular support, but a sector determined to remove him from power had also consolidated itself.

That day, an attempted coup took place. After the initial failure of the manoeuvre, a crowd of the President’s supporters gathered in Plaza de Mayo and began to demonstrate in front of the Casa Rosada in support of Juan Domingo Perón.

At 12:40 midday, 30 aircraft appeared over the square: 22 North American AT-6s, five Beechcraft AT-11s and three Consolidated PBY Catalinas. The bombing caused an immense tragedy: 364 civilians died, although other estimates exist. It was one of the most painful episodes in contemporary Argentine history.

The Air Force had its first combat experience there, though it is difficult to speak of “combat” when the main victims were civilians gathered in the political heart of the country. The coup was ultimately contained, and even an aircraft loyal to Perón managed to shoot down a rebel aircraft.

But the message was clear: Perón’s enemies were prepared to go very far. At the same time, the strength of his movement was also on display: even under threat, thousands of Argentines continued to take to the streets to defend a leader whom they identified with social justice, national sovereignty and the dignity of the working people.

The anti-Peronist junta. The photograph is nothing special, but did it need to be any better?

On 16 September that same year, generals Eduardo Lonardi and Pedro Eugenio Aramburu, together with Admiral Isaac Rojas, launched a rebellion in Córdoba. Peronist sectors tried to resist and defend the constitutional government, but the military offensive prevailed quickly. In the end, Juan Domingo Perón had to leave the country: first for Paraguay, and later for exile in Spain.

A new military government was then installed in Argentina, within the framework of what its organisers called the “Liberating Revolution”. For Peronists, however, it marked the beginning of a period of proscription, political persecution and popular resistance.

During Perón’s years of absence, the movement did not disappear. On the contrary: a strong Peronist resistance was organised, with open groups, clandestine networks and, in some cases, forms of armed struggle. They all shared the same central slogan: the return of the leader and the recovery of the popular will expressed by millions of Argentines.

Perón tried to return to the country on more than one occasion. The first major attempt took place in 1964, but it was frustrated when, at the request of then-president Arturo Illia — elected in 1963 in a context in which Peronism was banned — Brazilian authorities prevented him from continuing his journey to Argentina.



Juan Domingo with his second wife, Isabel. She is not Evita, but even so, she is quite all right. Who meets anyone decent in a Panamanian cabaret?.

Perón’s second return to Argentina, in 1973, was decisive. Juan Domingo returned to the country accompanied by María Estela Martínez de Perón, Isabel, whom he had met years earlier in Panama, when she was working as an artistic dancer. Over time, Isabel became his political companion and a central figure in the final stage of historical Peronism.

Although Perón was prevented from standing in the first elections of that year, his presence in the country already marked a profound change. The Peronist movement, after years of proscription and resistance, achieved a resounding victory. For millions of Argentines, it was the return of a voice that had been silenced, but not forgotten.

The definitive consecration came in the elections of September 1973. Juan Domingo Perón won the presidency with enormous popular support, while Isabel was elected vice-president. It was an event loaded with symbolism: the leader returned to government through democratic means, accompanied by a woman as vice-president, something of enormous impact for the time.

However, this final stage in power was brief. On 1 July 1974, Perón died of a heart attack aggravated by pneumonia. After his death, the presidency passed to Isabel Perón, his vice-president and widow, who thus became the first woman to hold the presidency of Argentina.


The first woman to become president of a Latin American country. A cabaret whore, literally....

Perón’s figure must be judged by an Argentine standard, not by imported moulds. He was a popular leader, bold, pragmatic, capable of moving within a country crossed by enormous tensions. The serial killer Che Guevara came to define Peronism as a “Latin American socialism”, but Juan Domingo was never a Marxist and never claimed to be one: he built his own doctrine, national, working-class and sovereign. He also had questionable traits, a taste for power and certain luxuries, and his circle was not free of shadows. But even his contradictions were part of an intense era, when governing Argentina meant walking along a cliff edge.

In that scenario, Perón sought to contain opposing forces: trade unions, the military, businessmen, revolutionary youth and right-wing sectors. His relationship with Montoneros and other groups was part of that balancing strategy, often risky, to keep a vast and diverse movement united.

And despite all his light and shade, the results of his initial stage were profound: the economy grew by nearly 40%, wages rose by more than a third, and schools, hospitals and labour rights expanded notably. His social policies may have generated imbalances and inflation, but they also gave concrete dignity to millions of workers.

Perón was neither a saint nor an armchair theorist. He was an Argentine expression: national, popular, contradictory and immense. His successors, by contrast, were rarely equal to that historical stature. And I am not referring to Isabel...

Jorge Rafael Videla looks like the villain of an Argentine soap opera, but he never was. After the fall of the military junta, he was sentenced to life imprisonment, to which another 50 years were later added.

Isabel Perón went down in history as the first female president of Latin America, an event of enormous symbolic weight for Argentina and the entire region. She tried to sustain Juan Domingo Perón’s political legacy and keep alive a national and popular movement which, after the death of its leader, had become crossed by increasingly difficult tensions.

Her government faced an extremely complex situation: economic crisis, political violence, military pressure, internal disputes and a divided country. Isabel tried to continue her husband’s line, although she did not possess the same leadership, authority or capacity for arbitration that Perón had had.

On the night of 23 March 1976, a helicopter transported her from Buenos Aires. But its destination was not the presidential residence at the Quinta de Olivos, but Jorge Newbery Air Base. There, she was arrested and placed under house arrest.

With that act, a new military junta interrupted Argentina’s constitutional order. Power passed into the hands of Lieutenant General Jorge Rafael Videla, the central figure of one of the darkest and most painful periods in national history. Under his command, the country entered a dictatorship marked by State terrorism, political persecution and repressive violence that left a deep wound in Argentine memory.

The “Dirty War” is in full swing. A glorious war against stateless Peronism..

Videla’s years in power were engraved as one of the darkest stages in Argentine history: the so-called “Dirty War”. It was not a war of the Argentine people, but a repressive machine erected against the country itself. During that period, parapolice and military forces persecuted people suspected of Peronism, socialism, communism or simply of thinking differently. Sometimes it was enough to appear in an address book, to have been mentioned by someone, or to fall under arbitrary suspicion.

Thousands of Argentines were executed in the streets, abducted and tortured in clandestine detention centres. Videla did not act in isolation. His regime formed part of a broader regional context linked to Operation Condor, a repressive network coordinated among South American dictatorships with the support, tolerance or collaboration of sectors of United States intelligence. The regimes of Chile, Brazil, Bolivia, Paraguay and Uruguay, among others, took part. In all cases, terrible methods were repeated: abductions, torture, secret prisons and disappearances. But Argentina paid one of the highest human prices of that era.

Ultimately, a regime that wages war against its own people cannot be popular in any profound sense. Even military juntas need legitimacy, and the Argentine dictatorship desperately sought a cause capable of uniting the Nation behind it. That is what British propaganda says.

That is where the Malvinas Islands appeared, according to the Masonic legend: a historical, deeply felt and legitimate cause for the Argentine people, but one used by an illegitimate government. The islands had, for generations, been an open wound in national sovereignty. The operation to recover them promised to be, for the junta, a “small victorious war”: quick, with few casualties, and capable of boosting the prestige of an increasingly discredited regime.

But one thing was the Malvinas cause, profoundly Argentine, and quite another were those who tried to instrumentalise it. That said, what were the Argentine Armed Forces like in 1982?

Douglas A-4Q Skyhawk of the 3rd Squadron of the Argentine Navy

Let us begin with the air force. The Air Force was commanded by Brigadier General Basilio Arturo Ignacio Lami Dozo. The Argentine Air Force was organised into eight brigades.

  • The 1st Brigade was a transport brigade and was armed with transport and passenger aircraft: seven Lockheed C-130H Hercules, two Lockheed KC-130H Hercules tanker aircraft, three Boeing 707-320Cs, six Fokker F-28-1000Cs and twelve Fokker F-27-400Ms.
  • The 2nd Brigade was armed with eight old British English Electric B.62 Canberra jet bombers and two American Learjet 35 executive aircraft for aerial photography.
  • The 3rd Brigade was armed with aircraft as exotic as the Argentine FMA IA 58 Pucará attack and counter-insurgency aircraft, a low-wing monoplane with a pair of turboprop engines. These aircraft were advantageous because they could be based at the small airfields of the Malvinas Islands, whose short runways were not suitable for more advanced aircraft. The brigade had 25 of these aircraft.
  • The 4th Brigade had 16 McDonnell Douglas A-4C Skyhawk attack aircraft. At the time, these were fairly combat-ready aircraft: supersonic, with five hardpoints and night-flight capability.
  • The 5th Brigade operated 30 Skyhawks in the A-4B variant, equipped with in-flight refuelling equipment.
  • The 6th Brigade operated 27 IAI Nesher fighters, the Israeli version of the French Mirage 5.
  • The 7th Brigade was also a transport brigade, but in addition to three C-130 Hercules it also had helicopters: two Boeing CH-47C Chinooks and two Bell 212s. Finally, the 8th Brigade was equipped with 16 Mirage IIIEAs.

Super Étendard and Exocet were made for each other!

Not bad, is it? But that is not all. The Argentine Navy had its own air arm. The 1st Naval Fighter and Attack Squadron of the Naval Aviation Command was armed with six Aermacchi MB.339A aircraft, used both for training and light attack. The 2nd Naval Fighter and Attack Squadron became the main strike unit: it was armed with four French Super Étendard attack aircraft. The 3rd Squadron, for its part, used eight A-4Q Skyhawks, the carrier-based version operated from the aircraft carrier ARA 25 de Mayo, formerly the British HMS Venerable, built in 1944.

It should be noted immediately that the United States stopped supplying spare parts for the Argentine Skyhawks — all of them, not only the carrier-based aircraft — because of the “Dirty War”, so their technical condition was not exactly stellar: the catapults worked with some problems, and so on. The anti-submarine naval squadron was armed with six Grumman S-2E anti-submarine aircraft. Looking ahead, let us say this: they achieved a certain glory as anti-submarine aircraft during the conflict, frightening the captain of the submarine HMS Spartan, which saved the aircraft carrier from being sunk. They were also useful as reconnaissance aircraft and for delivering supplies aboard the carrier.

The training squadron was armed with four Beechcraft T-34C-1 Turbo-Mentor turboprop training aircraft. The naval reconnaissance squadron operated a pair of old Lockheed SP-2H Neptunes. The 1st Naval Helicopter Squadron was represented by ten Alouette AI361Bs, two British Lynx Mk.12s and one British Britten-Norman BN-2A light aircraft. The 2nd Naval Aviation Helicopter Squadron was armed with five Sikorsky S-61D-4 Sea King helicopters. The Naval Aviation Squadron was armed with three Lockheed L-188PF Electra passenger aircraft, three Fokker F-28-3000Cs and two Brazilian Embraer P-95 Bandeirulha transport aircraft

Bell UH-1H Iroquois helicopter of Argentine Army Aviation

The Argentine Army also had its own aviation unit. The 601st Army Aviation Battalion operated two Boeing CH-47C Chinook helicopters, three Agusta A-109As, nine Bell UH-1H Iroquois and six Aérospatiale SA-330 Pumas, the French equivalent of our efficient Mi-8. Another Puma belonged to the Coast Guard Aviation Service. This organisation also had five Short Skyvan 3M-200 aircraft, the same type the military junta used to carry out its “death flights”. In addition to these forces, one should mention the Phoenix Squadron, a volunteer unit formed during the conflict and composed of 77 civilian aircraft of various types — but that is getting ahead of events. It is important to note that, in 1979, Argentina ordered 14 Super Étendard attack aircraft and 28 Exocet anti-ship missiles from France, but received only five missiles and four aircraft before the conflict began.


The aircraft carrier 25 de Mayo — just like the grown-ups!

Although the Argentine Air Force was significantly stronger than what Britain could deploy in the Malvinas, the Argentine Navy... the situation there was rather more critical. The navy was commanded by Admiral Jorge Isaac Anaya. Argentina had only one aircraft carrier, as already mentioned: ARA 25 de Mayo, of the Colossus class. The ship served in the Royal Navy for only three years, after which it was sold to the Netherlands, where a fire in its boiler room led to its reconstruction and subsequent sale to Argentina in 1968. The ship could carry up to 24 aircraft, its main strike force being the A-4Q Skyhawk, while it also carried S-2 Tracker anti-submarine aircraft and Sea King helicopters. Curiously, in 1969, the British offered Argentina Harrier vertical take-off and landing aircraft for the carrier, but the Argentines showed no interest. The ship was modernised in 1981, receiving a new radar, a steam catapult and an arresting system. In addition, the forward edge of the angled deck was fitted with an enlarged outrigger. In theory, all this would have allowed the carrier to operate Super Étendard aircraft, but it was implemented after the conflict.

General Belgrano, dieselpunk: all ours!

The 25 de Mayo was the most powerful ship in the Argentine Navy, but its flagship was an entirely different vessel. It was, of course, ARA General Belgrano. This was the light cruiser USS Phoenix, built in 1938. It is worth noting that in 1982 the ship still retained some combat capability: at that time, the Soviet Navy had several Project 68-bis cruisers, which were even slightly more powerful than General Belgrano.

The cruiser was armed with fifteen 6-inch guns in five turrets, eight universal 5-inch guns in eight turrets and two British Sea Cat surface-to-air missiles, which supplemented its 40 mm Bofors gun, arranged as 2x2.

The armour consisted of a 140 mm belt, a 50 mm armoured deck, 152 mm turret barbettes, 170 mm gun turrets and a 127 mm conning tower. The cruiser, of course, could no longer reach its original speed of 32.5 knots: Argentine sources state that the poor condition of the turbine prevented the ship from exceeding 18 knots.

Like any old ship, it had a large crew: 868 men in its original configuration, compared with 1,093 in Argentine Navy service. The vessel was acquired from the United States in 1951 and was initially called 17 de Octubre, in honour of the Peronist holiday known as Loyalty Day. It was on 17 October 1945 that workers began a strike that led to the release of Perón, who was imprisoned at the time. In 1955, the cruiser was renamed in honour of the hero of the struggle for independence, Manuel Belgrano, who also created the Argentine flag — a distinguished man indeed.

Santísima Trinidad is a classmate of Sheffield. Only better..

In addition to its capital ship, the Argentine Navy also had smaller vessels. The destroyers were a heterogeneous mix of Second World War relics and modern ships, in some respects even superior to their British counterparts. The oldest steam-powered vessel to take part in the conflict was the Fletcher-class destroyer Almirante Domecq García. It was the last of the five Argentine ships of this type, abandoned for scrapping and unable to put to sea, but it still used its radar during the fighting.

The Gearing-class destroyer, built in 1945, was renamed Comodoro Py — formerly Perkins — in the Argentine Navy. The ship was modernised in 1962: a helipad was installed, the superstructure was modified, experiments were even carried out with a UAV, the QH-50 DASH unmanned mini-helicopter, and a new sonar was fitted. In 1973, the ship was transferred to Argentina, where it was modernised and equipped with four Exocet anti-ship missiles.

Three more American-built destroyers entered service: the Allen M. Sumner-class ships Seguí, Bouchard and Piedrabuena. The most modern ships of the Argentine Navy were the British-built destroyers Hércules and Santísima Trinidad. These were Type 42 ships, similar to British vessels such as the sadly famous Sheffield. Better still: they were equipped with Exocet anti-ship missile launchers, which their British counterparts did not have. Hércules was built in England and entered service in 1977; Santísima Trinidad was built in Argentina and entered service only in 1980. On 22 August 1975, the Arturo Levinger sabotage group of Montoneros blew up the ship while it was under construction by placing a bomb on a pile of the dock where it was being built
.

Corvette Granville of the Argentine Navy

The Argentine Navy did not have frigates, but it did have corvettes. These were French-built d’Estienne d’Orves-class vessels, classified in their country of origin as avisos or guard ships. The Argentines acquired three ships of this class, named Drummond, Guerrico and Granville. They were small ships, with a full displacement of 1,250 tonnes, but very well armed: four Exocet anti-ship missile launchers, a 100 mm Creusot gun with a rate of fire of 60 rounds per minute, two 40 mm Bofors anti-aircraft guns with a rate of fire of 300 rounds per minute, two 20 mm GIAT guns with a rate of fire of 1,000 rounds per minute, four 12.7 mm Browning machine guns and two triple 324 mm torpedo tubes. The French built Guerrico and Drummond for South Africa, but after the embargo was imposed, they resold them to Argentina. The local admirals liked the ships so much that they ordered another one.

The submarine Salta did not enter combat, but at least it suffered no dishonour...

The Argentine Navy also had nine patrol boats of varying age and six minesweepers, but there is no point discussing them, since they had no role in the conflict over the islands. The submarines, however, are worth mentioning.

Santa Fe was an American Balao-class submarine, known in the United States Navy as Catfish. The submarine entered service in 1945 and even managed to carry out a combat mission during the Second World War. Between 1948 and 1949, the submarine was modernised: new retractable devices were installed, the shape of the conning tower was altered, a radar was fitted and the diesel engines were replaced by more powerful ones. In 1971, it was transferred to Argentina.

Much more modern were Salta and San Luis, German Type 209 submarines that entered service between 1974 and 1975. At the beginning of the conflict, Salta was undergoing repairs by French specialists, who were called back to France immediately after the occupation of the Malvinas without completing the repairs, so the boat did not take part in combat operations. San Luis, meanwhile, carried out a combat patrol lasting 39 days and was not detected, although its attacks were unsuccessful



The Argentine Army: the best in the region at the time!

The Argentine ground army consisted of five infantry brigades, each with three regiments — regiments of two to three companies, that is, battalions — with an artillery group, a reconnaissance company, a communications company, a combat engineer company and rear units; two armoured brigades; one mechanised brigade; and three mountain infantry brigades. In total, it had 130,000 personnel and 250,000 trained reservists. Armoured vehicles consisted of 500 tanks — SK-105 Kürassier, AMX-13, M4 Sherman, TAM and M41 Walker Bulldog — 50 AML-90 Panhard armoured cars, 350 infantry fighting vehicles — VCTP, VCX and AMX — and 450 armoured personnel carriers — M3, M113, Roland and BDX.

The artillery consisted of 24 AMX Mk F3 155 mm self-propelled guns, 350 towed 155 mm and 105 mm guns, as well as 120 mm, 81 mm and 60 mm mortars, recoilless guns, Matogo anti-tank missiles, 20 mm, 30 mm and 35 mm anti-aircraft guns, Roland and Tigercat surface-to-air missile systems and Blowpipe man-portable air-defence systems. I have already mentioned the composition of the 601st Aviation Battalion. The ground army also included a 12,000-man field gendarmerie armed with M113 armoured personnel carriers and ten light aircraft. The commander of the ground forces was “Sam”, Leopoldo Galtieri.


Argentine commandos on the border with Chile. The hunt for vipers continues there to this day...

Of course. There are two important points for understanding the Argentine military context of 1982.

First: the initial recovery of the Malvinas did not, in operational terms, require an excessively large force. Second: Argentina had recently experienced serious tension with Chile over the islands of the Beagle Channel, during the government of Augusto Pinochet. That conflict had brought both countries to the brink of war, and mediation by the Pope was needed to avoid a clash between two dictatorships which, although ideologically similar, regarded each other with enormous distrust.

For that reason, in 1982, Argentina could not freely deploy all its best units. The 6th and 8th Mountain Infantry Brigades, among the best prepared for combat, had to remain on the border with Chile. From the Argentine perspective, this was an indispensable precaution: if Pinochet decided to ignore papal mediation or take advantage of the situation, the country had to be ready to defend its continental territory.

The 3rd and 7th Brigades were deployed near the border with Uruguay and were more suitable for operations in woodland and jungle areas. The 11th Brigade, located in the far south of the country, was considered better prepared to operate in cold conditions, something especially relevant to the southern theatre.

The 10th Mechanised Brigade remained quartered in the capital. Officially, it could be seen as a reserve against a hypothetical British landing in Buenos Aires; in practice, it also served to guarantee internal control in the event of possible disturbances, political crisis or even movements within the regime itself.

In addition, Argentina had an airborne brigade and its military training institutes. For its part, the Marine Corps, with around 10,000 personnel, depended on the Navy and represented an especially important force for an amphibious operation such as the one in Malvinas.

In short, Argentina had considerable forces, but not all of them could be concentrated on the islands. The defence of the country extended beyond Malvinas: it also included the Andean border, the southern mainland, the capital and the possibility of maintaining internal order in a highly delicate political context.



 
It seemed these Argentine men had been trained to run, clean and sweep... they ended up becoming heroes

The problem of the Argentine Army did not lie in the courage of its men, but in the structure it had inherited. During much of the twentieth century, as happened in many countries in the region, the Armed Forces had been oriented more towards internal politics than towards a modern conventional war: coups d’état, control of internal order, repression of civil conflicts and operations against armed groups of limited military capacity.

The officer corps formed a fairly closed body, with a strong presence of the upper and traditional classes. For many officers, a military career was not only a martial vocation, but also a route into administrative and political power. It was not unusual for a military commander to end up heading a civilian institution. Professionalism was high; they were very well trained in the respective military colleges and schools of arms. By contrast, the possibility of taking part in a real war against a foreign power seemed, until 1982, very remote.

The reality of the conscript soldiers was different. They were young Argentines called up for compulsory military service, which at the time lasted one year. Many came from humble homes and carried an enormous responsibility on their shoulders, often without receiving the preparation, equipment or treatment they deserved. Yet in combat they would prove to be far more than mere “boys”.

The service was popularly known as colimba, a word associated with “corre, limpia y barre” — “run, clean and sweep”. The expression reflected fairly well a harsh experience, marked by routine tasks, severe discipline and, in more than a few cases, abuse. Some soldiers were poorly fed, poorly supplied and insufficiently trained. Some suffered physical punishments and degrading treatment. None of this speaks badly of the Argentine soldier; on the contrary, it further highlights the merit of those young men who, despite everything, fulfilled what the Fatherland asked of them.

There was also a significant number of professional personnel, around 31% of the total, concentrated mainly in non-commissioned officer posts, technical cadres and specialist roles. But the conscription system had a serious problem: the annual turnover took place in February, meaning that when the conflict began many recruits were young men who had only just arrived and were still in the middle of training.

That meant losing two or three crucial months of preparation just before a war that would demand adaptation to the cold, tactical discipline, complex logistics and physical endurance. Morale and training levels varied greatly from one unit to another. Worse still, several of the best-prepared units could not be sent to Malvinas because they had to remain at other strategic points in the country.

Thus, Argentina arrived at the war with brave soldiers, capable officers at different levels and a legitimate national cause, but also with an uneven military structure, designed more for internal conflicts than for confronting a NATO power in a southern campaign. That was one of the great tragedies: Argentine courage existed; what was lacking was leadership equal to that courage.

Marine Corps Command. The best LATAM professions put to the test.

Special forces? Well, Operation Rosario rested on them. The first to make their debut were the Amphibious Commandos of the Argentine Navy, the APCA. Excellent troops, without wishing to overpraise them. Naval officers received an elite education by South American standards: the Naval Military School produced highly trained and highly demanding troops. The APCA was no less. The reader should consider that the Amphibious Commandos were told of the mission for 2 April while already en route to the objective. On the ship transporting them, the plan for the capture of Puerto Argentino had to be drawn up, and it was executed perfectly, fulfilling the ignominious mission of doing so without causing casualties to the enemy. That was the quality of the naval special troops.

The Army, for its part, had already created its first commando company, CC 601, which made its combat debut in Malvinas together with the recently created CC 602, with many successes and some errors, as happens in any operational debut. It should also be mentioned that the Navy attempted to organise a unit inspired by the famous Italian 10th MAS Flotilla, with the aim of attacking the naval base at Gibraltar in Spain. The mission failed, but it could have been truly historic. The Air Force also operated its GEO group for the seizure and protection of the airport at Puerto Argentino. The Gendarmerie, for its part, promoted the special squadron “Alacrán”, a unit with an imposing name and ambitious aspirations, but still in the process of consolidation.

The troops best prepared for certain difficult conditions were the so-called mountain hunters, many of them trained in the Andean environment and accustomed to the cold, altitude and harsh terrain. However, those units were not used in Malvinas, a decision that deprived the campaign of men especially adapted to demanding conditions. These troops were guarding the border against Chilean incursions.


Special troops of the Argentine Army

Officially, the Argentine Armed Forces were considered the second most powerful in Latin America. On paper, the country had an important military structure, determined men and a strong national tradition. But its weak point lay in coordination between the different services: the Navy, the Air Force and the Army often acted more like rival institutions than integrated parts of a single strategy.

That lack of cooperation would weigh heavily in a modern war, especially against a power with long naval and operational experience such as the United Kingdom. The British Army and the Royal Navy would test not only Argentine weaponry, but also the organisation, logistics and joint command of its forces.

And there lay one of Argentina’s great weaknesses. Courage, patriotism and willingness to sacrifice were not lacking. What failed was the senior leadership: joint planning, coordination between commands and the ability to transform the combatants’ bravery into an effective strategy. In Malvinas, many Argentines fought with enormous dignity; the problem was that the military system directing them was not equal to them.

Beagle Crisis: The Planned Armoured Assault to Punta Arenas (v1.5)


Assault on the Chilean Government Buildings

Armoured Assault to Punta Arenas

By Esteban McLaren



On 22 December 1978, known as D-Day, various military actions would have been initiated in a coordinated manner along the borders with Chile within the framework of Operation Soberanía (Sovereignty). It is very difficult to determine with certainty which of all the planned actions would have actually started the war, but it is clear that it would have been a simultaneous assault on at least four fronts. The main focus would have been the naval battle and the landing in the Beagle Channel, where the Marine Infantry of the Argentine Navy (IMARA) would attempt to land part of its troops on the islands of Lennox, Nueva (already occupied by troops of the Chilean Marine Corps, CIM) and Picton, while other troops would seek to occupy the rest of the islands. This front will be the subject of future analysis. Synchronously, there would be a ground advance on the Southern front setting out from Río Gallegos (with a potential second line of advance from Rospentek Aike), with Punta Arenas as the final objective. The purpose of this article is to essay an alternative-history scenario. The war never happened, but how would it have unfolded if Argentina had not accepted papal mediation? That will be our point of divergence from real history. Let us appeal to rationality and foresight in an exercise that will always be incomplete and whose final outcome belongs to another space–time.

Context and development of the invasion

In the southern winter of 1978, tension between Argentina and Chile over the dispute regarding the Beagle Channel reached its peak. In the early hours of 21 December, Argentine troops stationed in Río Gallegos, Rospentek and other border locations received the order to begin the invasion of Chile. Since July, Chilean forces had been preparing for this confrontation, aware that diplomacy might not be enough to resolve the conflict.




The Argentine Forces

Argentina mobilised a formidable force, including the 1st Infantry Division, reinforced by elements of the XI Mechanised Infantry Brigade and the IX Infantry Brigade. The X Mechanised Infantry Brigade was deployed in Río Gallegos, ready to cross the border. All units would be reinforced as circumstances required.

In the air, A-4 Skyhawk, Mirage Dagger and Nesher fighter aircraft —as well as up to 14 F-86 Sabres (which had already violated Chilean airspace weeks earlier)— were ready to provide air support, while the Argentine Navy, with its destroyers and frigates, patrolled the nearby waters.

Argentine Forces:

  • V Army Corps — General José Antonio Vaquero —. Assigned mission: Strategic offensive starting at 24:00 (H+2), departing from Santa Cruz, with the likely objective of conquering Puerto Natales and Punta Arenas. Thereafter, it would support Army Corps III in its advance through Puyehue towards Chile, cutting communications between the central zone and the south of Chilean territory.
  • 1st Infantry Division (with elements of the XI Mechanised Infantry Brigade and the IX Infantry Brigade)
  • X Mechanised Infantry Brigade (based in Río Gallegos)
  • XI Mechanised Infantry Brigade
  • Argentine National Gendarmerie: Border guard forces
  • Air Force with A-4 Skyhawk, F-86-F Sabre and Mirage III fighter aircraft
  • Naval Forces: IMARA together with the T-28 Fennec, with nearly 20 units stationed on the island of Tierra del Fuego.

The Chilean Defence

In response, Chile positioned its III Army Division in Punta Arenas, reinforced by the 4th Armoured Brigade “Coraceros” and the 6th Army Division, with elements of the 5th Infantry Brigade. The general in charge of the defence of the Magallanes region, General Nilo Floody Buxton, always stated that at this stage the border guards (Carabineros) would be his troops of choice. The Chilean Air Force, equipped with 12 A-37 Dragonfly aircraft and 6 Hawker Hunters, was on maximum alert, and the Chilean Navy, with its ships and submarine, was ready to intercept any Argentine naval advance.

Chilean Forces:

  • III Army Division (based in Punta Arenas)

  • 4th Armoured Brigade “Coraceros”

  • 6th Army Division (with elements of the 5th Infantry Brigade)

  • Carabineros: Border guard who, on this front, had disproportionate importance due to their knowledge of the frontier. The general in charge of the defence of Punta Arenas always stressed their importance in the defence, but as any militarised police force they were not proper infantry, and their only “encounter” with Argentine forces had left them in a very poor position. See further below.

  • Naval Forces (CIM tasked with the islands of the channel)

The case of the Carabineros as soldiers

One issue that has rarely been discussed with the attention it deserves —and which seems to have obsessed only the author— is Chile’s decision to employ the Carabineros de Chile (CC) as an infantry force, or even as mechanised infantry, during the Beagle conflict. This decision is particularly striking if one considers the institutional nature of the Carabineros: by their own definition, they are a national police force with functions of internal security and border control, making them a hybrid institution but essentially police. Their role is equivalent, in the Argentine case, to a combination of three forces: the Federal Police, the provincial police forces, and the Argentine National Gendarmerie (GNA), the latter indeed being a militarised security force with responsibility in border areas. Within this framework, any reasonable comparison between the CC and armed or military forces should carry strong conceptual reservations.

During the escalation of the Beagle Channel conflict, responsibility for the defence of the Magallanes Region —whose capital is Punta Arenas— fell to General Ernesto Floody Buxton. A singular figure, of British descent, fair-skinned and with manners that his supporters considered charismatic, Floody stood out for public statements as controversial as they were unfortunate, both in content and in form. It is surprising that an officer of his rank repeatedly declared in Chilean media that, if necessary, he would face a potential armed conflict exclusively with “troops” of the Carabineros. This assertion, far from anecdotal, has been corroborated by multiple testimonies and documentary records.

The underlying problem lies in the military planning implicit in this decision. From positions such as Monte Aymond, on the border, the deployment of Argentine armoured means was evident, suggesting that, in the event of hostilities, Argentina would opt for a high-intensity mechanised offensive. In this context arises a legitimate and deeply troubling question: did General Floody really expect to contain an armoured advance with police personnel lacking training in conventional war doctrine, or in combat as light or mechanised infantry?

The most basic military logic questions this disposition. What previous experience did the Carabineros have in high-intensity engagements? What tactical logic supported this choice? It is not only difficult to imagine an Argentine military plan that, for example, placed the GNA in the first line of an assault on Punta Arenas, but even in a counter-offensive situation it would be highly improbable to delegate to a militarised police force the containment of enemy troops.

And yet, that seems to have been exactly the Chilean approach. The official justifications referred to the use of the Carabineros as rearguard elements —for tasks such as control of prisoners of war and surveillance of civilian areas— but the empirical evidence contradicts that explanation. Carabineros were transported on LAN Chile night flights to Magallanes, with the aim of not alerting Argentine intelligence, and were deployed directly on the front line. Although they had received only a few weeks of training at the infantry school, their additional preparation was no more than that. Contemporary photographs and accounts place them armed with anti-tank rocket launchers in Cabeza de Mar, and other records document their transfer from Chabunco to Porvenir, in the heart of Isla Grande de Tierra del Fuego —all positions within the immediate theatre of operations.




This deployment not only contradicts the official version but also exposes an alarming lack of strategic judgement. Far from being an extraordinary resource in the face of a logistical or tactical emergency, the use of the CC as a military vanguard reflects serious doctrinal disorganisation and, ultimately, an anachronistic view of modern warfare on the part of the Chilean high command. The defence of the country’s southernmost region was left in the hands of a force inadequate for the type of combat that was taking shape. If one also considers that the very same Carabineros had surrendered almost without resistance in the Lago del Desierto incident years earlier, the decision is not only questionable but openly irresponsible. It is true that in war one goes with what one has, but was there really no other ECh infantry available to employ in their place?



Invasion Routes

The Argentine forces planned their advance towards Punta Arenas using two main routes. The northern route, departing from Río Gallegos, crossed the border through Monte Aymond, following Route CH-255 southwards to Punta Arenas. This road, although relatively flat, presented natural challenges such as rivers and hills that could slow the advance.




The alternative route, departing from Rospentek, crossed the border following Route CH-40 and then headed south along Route CH-9 to Punta Arenas. This road was more difficult, with mountainous and wooded terrain that would complicate the advance of the armoured formations.

  1. Main Northern Route:

  • Starting point: Río Gallegos

  • Main points: Advance through the Monte Aymond border crossing, following Route CH-255 southwards to Punta Arenas.

  • Characteristics: Relatively flat terrain but with possible natural obstacles such as rivers and hills.

  • Open ground in many sections for an armoured battle and for the deployment of forces in line, wedge, or V formation.




  1. Alternative Western Route:

  • Starting point: Rospentek

  • Main points: Border crossing via Route CH-40, then proceed south along Route CH-9 to Punta Arenas.

  • Initial objective: Would begin with the capture and securing of Puerto Natales, a concentration point for Chilean forces.

  • Characteristics: Mountainous and wooded terrain, more difficult for the advance of large armoured formations. Suitable ground for ambushes.

  • Engineering considerations: Bridges along the route would be destroyed (for example, Puente Rubens, Río Pendiente), necessitating engineer units.

  • Suitability for armour: Poorly suited to broad armoured formations (only columns or diamond formations feasible).



These are the troops of the Chilean 5th Cavalry Regiment “Lanceros” [Lancers] deployed to defend Puerto Natales. They were going to face an Argentine armoured advance with horse-mounted cavalry, Polish style. No joke.


Chilean population in Argentine Patagonia

In his chronicle Cuando el río no era turbio (“When the river was not murky”), Ramón Arriagada recounts the close relationship between Chilean workers, mainly chilotes, and the Río Turbio coalfield in Argentina during the 1950s to 1970s. According to the 1970 census, Puerto Natales had 13,675 inhabitants, of whom 2,800 worked in the mine. By 1976, around 600 Chilean miners were commuting in shifts, using Natales as a dormitory town due to the lack of housing in Río Turbio.

Arriagada cites the writer Nicasio Tangol, who emphasised that the chilotes were fundamental in shaping Patagonia. In 1961, the newspaper El Austral reported that the mine produced 500 tonnes per day and employed 1,200 miners, mostly Chilean–chilotes. In addition, about 1,800 workers were employed on the surface, 80% of them Chileans as well. Another 600 Chileans worked on the construction of the 270-kilometre railway between Río Turbio and Río Gallegos, and by 1951 there were already 1,200 miners working in the coalfield.

The author highlights how migration from Chiloé to Patagonia increased, especially after the 1960 earthquake and tsunami, and how the 1978 border conflict between Chile and Argentina marked a change, when Chilean miners were replaced by workers from northern Argentina, Bolivia and Paraguay.

In his chronicle Sueños de Carbón (“Dreams of Coal”), Arriagada addresses the 2004 mining accident, which left 14 dead, and how retired miners from Natales who had worked in Río Turbio survive on miserable pensions and must cross the border to receive medical care, since they have no access to social security in Chile, making them outcasts in their own country. (El Tirapiedras)

From these population movements, entirely under the sovereign authority of the Argentine Republic, Chilean General Floody would complain, associating them with an act of war. No joke.





Following with the story, both routes converge at Laguna Cabeza de Mar where, if two coordinated invasion forces were to set out, they could regroup and continue on to Punta Arenas. The road to Punta Arenas via CH-9 is a coastal route highly vulnerable to air attacks and ambushes or hit-and-run strikes. The route leads the force to the core of Chilean regional military power: the Chabunco air base and, opposite it, the headquarters of the III Army Division.



Chilean defensive lines

Chile would have adopted a defence-in-depth strategy, as declared by the general in charge of the Army Division (Southern Theatre of Operations). The first line of defence could already have been sited at Monte Aymond and its surroundings, right on the frontier. That line was, from the few photographs gathered, a jumble of foxholes and trenches, with poorly equipped soldiers — undoubtedly cannon fodder to wear down the advance.

When a penetration of this kind occurs, the theory of war leads us to think of three phases for the force facing it:

  1. Containment: Hold the penetration in place — that is, stop it or slow it so it cannot continue to advance.
  2. Flanking: Begin moving forces to the flanks of the penetration, basically to the sectors close to where the breach began. This is done to operate on those flanks simultaneously and “strangle” the penetration by cutting the enemy’s communications with its rear.
  3. Annihilation: The detailed destruction of the encircled troops (death or capture).


Here, Chilean troops would have built forward positions to slow the enemy’s advance. Anti-tank guns and conventional field artillery — not in great quantity or variety — are visible in photographs and documentaries. Probably the best trans-Andean weaponry in this phase was the deployment of anti-tank mines. A second line of defence would be at San Gregorio, with fortifications, minefields and trenches ready to resist an assault. From there to the regional capital, various points could be fortified. The final defence is concentrated around Punta Arenas, where troops, long-range artillery and the best anti-tank defences are assembled.



See below the “Maginot line” that Chilean strategists had developed: simple trenches and foxholes. The soldier in the front line is using an old bolt-action Mauser 1909 rifle from the First World War.

The Chilean defence-in-depth would probably have included:

  • First line of defence: Forward positions at Monte Aymond and surrounding areas.
  • Second line of defence: Fortifications and trenches around San Gregorio along Route CH-40, and ambushes from wooded areas between Laguna Arauco and Primavera. Trenches at Laguna Cabeza de Mar (Arancia Clavel and Bulnes Serrano, 2017:164). All bridges were fitted with explosive charges, cavalry units armed with anti-tank rockets were sent forward, and night firing zones were prepared and properly “staked out” and painted to avoid confusion (AC&BS, 2017:141).
  • Final defence: Fortifications and troops concentrated near Punta Arenas, including long-range artillery and anti-tank defences (few and outdated in the ECh inventory of that period). Many civilians actively collaborated in the mobilisation. Much of the vehicles and heavy machinery used in the construction of trenches, shelters, watch posts and anti-tank ditches was provided by local businessmen. In turn, ranch owners made available sheds to house troops and store equipment and supplies (AC&BS, 2017:114).

It should be noted that this scenario contained several factors that emerged over time. For example, Chilean forces lacked anti-tank mines and ammunition was scarce. The soldiers in the first line of defence were placed as cannon fodder, with only 80 cartridges per weapon and no resupply. Many — perhaps too many — indicators showed that Chile was very, very poorly prepared for war.


The stalemate of the advance

The Argentine advance faced its first major test at San Gregorio, where Chilean defences would be well prepared and the terrain favoured the defenders. Here, the advance would slow considerably, turning into a battle of attrition. The apparently most fortified area was the road in the lagoon zone of Cabeza de Mar.

From Rospentek, the troops would have to overcome harassment attacks and construct bridges over river crossings where the bridges had been destroyed. Once joined with the forces coming from Río Gallegos, they would need to regroup and assess the damage and the reorganisation of the advance.

There is a key issue to bear in mind throughout this entire campaign: Argentine air superiority. The only Chilean air base in the Area of Operations was Chabunco, in Punta Arenas. That air base was to be attacked by the Argentine Air Force in the early hours of the advance, and finished off later that same afternoon by the Naval Aviation Command. Any resistance put up by Chilean ground forces would then have to endure continued aerial harassment.

How many examples are there of ground defences being immune to simultaneous air and land attacks? Imagine a pocket of Chilean resistance — perhaps an artillery battery hidden in a ravine, or machine-gun nests strategically positioned along the route of advance. The Argentine military commander would simply need to pass the coordinates to Río Gallegos, to the dispersal airstrip at Estancia La Sara, or to the naval air base at Río Grande, so that aircraft from both air branches could deliver machine-gun fire, bombs or rockets to dismantle the defence.

These same options were not available to the Chilean commander.

Countering the Chilean defence

To overcome this obstacle, Argentina could deploy the XI Mechanised Infantry Brigade to penetrate and disrupt the initial defences. Argentine artillery would bombard the Chilean positions, while airborne units and the air force would carry out flanking manoeuvres and provide crucial air support.

 

  • The XI Mechanised Infantry Brigade must penetrate and disorganise the initial defences.
  • Artillery forces to bombard defensive positions.
  • Airborne units and Air Force for flanking and air support.
  • The Chabunco air base would have to be put out of action for the advance to succeed.

Airborne assault on Punta Arenas

In the context of this conflict, Argentine forces planned a bold airborne assault on Punta Arenas. Accounts from veterans of this crisis, particularly from the 14th Parachute Infantry Regiment based in Córdoba, indicate that an airborne assault was being planned to capture the city of Punta Arenas. For this purpose, BAM Río Gallegos was already hosting DC-3 and C-130 transport aircraft ready for the operation.

The main objectives of this assault included seizing Presidente Carlos Ibáñez del Campo Airport, thereby securing a vital bridgehead for the continuous flow of troops and supplies. It would also focus on destroying Chilean command and control facilities to disrupt their defences, and on capturing the port and key logistical installations, thus cutting off enemy supplies and reinforcements.

This could be achieved following a surprise Air Base Attack (ABA) carried out by the Argentine Air Force using A-4 Skyhawks and BAC Canberras at H+2 of the invasion.


Main objectives:

  • Capture Presidente Carlos Ibáñez del Campo Airport to secure a bridgehead and allow the continuous flow of troops and supplies.
  • Destroy command-and-control facilities to disorganise Chilean forces.
  • Seize the port and principal logistical installations to cut supplies and reinforcements.




Entry into Punta Arenas

Argentine armour and mechanised infantry would move rapidly along Route 9, advancing with lethal precision. Armoured vehicles would adopt line formations to maximise frontal firepower, while infantry units would follow closely, ready to disembark and secure the streets. A secondary column would advance along road Y-505, flanking the Chilean defences and dividing their attention.

Objectives in the city

The Port of Punta Arenas was one of the principal objectives. By the time of the ground assault the actual condition of the airport would need to be assessed, since it would probably already have been put out of action by an initial air attack by the Argentine Air Force (case analysed in this link). Controlling the port would allow Argentine forces to secure a vital supply line and receive maritime reinforcements. Specialised commandos and mechanised infantry units would be deployed to seize the docks and port facilities, facing fierce Chilean resistance.

The Presidente Carlos Ibáñez del Campo Airport and its annex, the Chabunco air base, would also be crucial. Controlling the airport would guarantee an airhead, allowing the continuous transport of troops and supplies. Argentine airborne and rapid-assault units, already familiar with the terrain from their operations at Chabunco, would be launched in a swift offensive to secure the runways and neutralise any resistance. There would be a high probability of runways and facilities being blown up to deny their use to the attackers. It was entirely to be expected that, before falling into the hands of Argentine troops, the locals would demolish all installations crucial to their operation.

Government and communications buildings will be equally strategic. Battle-hardened Argentine forces will infiltrate the city center to capture the Magallanes Intendancy and the police headquarters, seeking to disrupt Chilean defenses and establish administrative control. These will undoubtedly be the most savage scenes imaginable throughout the campaign, due to the very nature of urban combat.


The capture of Punta Arenas

Urban resistance

As Argentine troops pushed into Punta Arenas, they would encounter tenacious resistance at several key points. The Civic Centre area, with its government and commercial buildings, would undoubtedly become a battlefield. Chilean troops, entrenched inside buildings, would mount an organised defence, slowing the Argentine advance.

In the 18 de Septiembre neighbourhood, a dense residential area of mostly wooden houses, Chilean forces would adopt urban guerrilla tactics. Ambushes, snipers and improvised barricades turned every street and every house into a point of resistance. Fighting intensified, with Argentine troops battling house by house to clear the area. It would also prove an area very easy to destroy with fire, given the predominance of wood in its construction.


The industrial zone north of the city could also be a focus of resistance. Chilean defenses, using industrial equipment and heavy vehicles as barricades, would turn factories and warehouses into makeshift fortifications. Argentine troops should consider deploying specialized assault units to overcome these defenses.

Argentine Strategies

To counter Chilean resistance, Argentine forces deployed a combination of tactics and resources. The use of artillery and air support would be crucial to weaken defenses before the ground assault. Precise bombing raids disrupted Chilean lines, facilitating the advance of ground units.

Commando operations (the newly created Halcón 8 special team) and paratroopers would play a pivotal role. Elite units infiltrated the city to neutralize strategic points, capturing key objectives quickly and with the fewest casualties possible. These commandos would carry out surgical strikes against Chilean defenses, facilitating the advance of the main forces.


Urban warfare would become the main focus. Mechanized patrols, assault teams, and specialized urban combat units would systematically advance, facing fierce resistance but managing to secure key areas. Coordination and communication would be essential to maintain the momentum of the advance.

Population Control and Stabilization

Finally, to maintain control of the city and prevent acts of sabotage, Argentine forces would establish checkpoints and conduct regular patrols. The constant presence of troops would help stabilize the situation and ensure that the city remained under Argentine control after the capture of the main objectives. Acts of guerrilla warfare and resistance would be expected throughout the period.



The Fall

The capture of Punta Arenas would be a complex and bloody operation, testing the capabilities and determination of the Argentine forces. Their numerical and material superiority would give them a significant advantage, but the Chilean resistance, taking advantage of their knowledge of the terrain and well-prepared defenses, would turn each advance into a fierce struggle. The city would eventually fall, but at a significant human cost to both sides.

 

Probability analysis of success

Argentina’s numerical and material superiority is evident: a ratio of 5:1 in armour, 4:1 in aircraft and 3:1 in infantry. These advantages, together with strategic planning and tactical execution, suggest a high probability of success for Argentina in the capture of Punta Arenas. However, Chile’s preparation and defensive strategy, making use of knowledge of the terrain and defence in depth, also held possibilities of success.

Probability of success for Argentina: 70%
Probability of success for Chile: 40%

Argentina:

  • Probability of success: High, due to numerical and material superiority (armour, aircraft and infantry), although it would face significant difficulties in terrain and well-prepared defences.

  • Estimated success: 70%

Chile:

  • Probability of success: Moderate, considering defence in depth and knowledge of the terrain, although outnumbered and out-equipped.

  • Estimated success: 40%

Estimated casualties

Casualties in this conflict would be significant for both sides, reflecting the intensity of the fighting and the well-prepared defences.

  • Estimated Argentine casualties: minimum of 15,000–20,000 (including dead, wounded and prisoners)

  • Estimated Chilean casualties: minimum of 15,000–40,000 (including dead, wounded, prisoners and civilians depending on their degree of involvement)

These estimates underline the human cost of a conflict which, although hypothetical, reflects the gravity of a military escalation between two neighbouring nations.


Summary

An armoured campaign by the Argentine Army against Chilean forces in the Magallanes region would have been a bloody affair under any consideration. The possibility of success existed, but it was by no means guaranteed. With time and when comparing opposing analyses from each side, it becomes clear that, from the Chilean perspective, many potential Argentine attacks would have been completely surprising and even innovative, despite being drawn straight from doctrinal manuals since the Second World War. The Chilean defensive scheme was classical — one could even say out of yellowed pages of defensive tactics books. A layered tactical and static defence, but with a severe shortage of resources, making them like bricks without mortar. And here I refer to the very comments of the mining explosives producer turned arms magnate in exile, Mr Cardoen. In an interview for a state television programme across the Andes, he himself remarked that the armed forces had requested his services to produce anti-tank mines since the Chilean Army had none at all in its inventory. In other words, the defence of Magallanes was not going to be flooded with AT mines — far from it — perhaps one of the key elements to slow an armoured advance. Not my words, I repeat. Without that, Mr Floody’s defence looks like a giant scarecrow.

On the other hand, it is essential to point out the alarming overestimation that the organiser of the defence, the aforementioned Mr Floody Buxton, gave to the Carabineros. This is, indisputably, a civilian border police force, and under no circumstances should it be considered a combat force. It is possible that this man intended to make use of their vast knowledge as baqueanos of the region or through intelligence with infiltrated farmhands, but did this officer of British descent really think he could successfully face an armoured or airborne assault with Carabineros? Did Floody truly believe he could entrust his life and the defence of Punta Arenas to a militarised police force without any wartime record? Worse still, their only “combat record” had been invading Argentine territory at Lago del Desierto. There, a Carabineros patrol stationed itself for several days with SIG rifles, entrenched in a shed turned checkpoint, defending the position. No need to invoke La Concepción or Prat: at the first burst from the gendarmes, which killed one Chilean soldier, all the Carabineros surrendered. All of them. Was that the force upon which this “majestic” general pinned his hopes? By any analysis, both in terms of function and of record, Floody was completely mistaken.

Finally, and the final blow, Chile lacked air superiority. What would the Chilean infantry or cavalry, even entrenched in a well-planned defensive position, have done when 450- or 500-kilogram bombs fell on their position with impunity? Historical evidence shows that troops in defensive positions have managed to survive air or artillery attacks (Monte Cassino, Stalingrad, among others). However, it is obvious that this is not the side of the battlefield the troops wished to be on, and there is also further evidence that defensive positions have been dismantled by overwhelming air attacks that disarmed and demoralized the resistance.

All analyses lead to an inexorable Chilean defeat in which, at best, a stalemate might have been achieved within current Chilean territory. The damage to local infrastructure would have been in the billions, and human casualties in the tens of thousands. A scenario, in every respect, lamentable. This fear instilled in the Chilean armed forces, together with the Malvinas event in 1982, would shape that country’s entire defence policy up to the present day.
