The 1905 Radical Revolution

1905 Radical Revolution





On February 4, 1905, the civil-military revolution organized by the Radical Civic Union and led by Hipólito Yrigoyen took place, which attempted to overthrow the constitutional government of Manuel Quintana, demanding free and democratic elections. It was one of the most important rebellions that Argentina suffered up to that time, due to the number of soldiers involved, the forces linked and the extension of the movement throughout the country.



Towards the end of 1893, the Radical Civic Union was facing its first internal dispute and was divided into two groups: the red radicals who supported Leandro Alem's leadership of the party, and the lyrical radicals who supported Hipólito Yrigoyen's interpretation of the seizure of power and his leadership in radicalism.



The Reds were in favor of revolution as a method to change the prevailing system while the Lyrics were considered "evolutionists" and did not trust in carrying out a coup d'état as a method for the changes they considered necessary..




Alem was supported within the party by leaders such as Bernardo de Irigoyen, Francisco Barroetaveña, Leopoldo Melo, Mariano Demaría, Lisandro de la Torre, Vicente Gallo, Simón S. Pérez, Joaquín Castellanos, Adolfo Saldías, José Nicolás Matienzo, Martín Torino, Mariano Candioti , Adolfo Mugica, Víctor M. Molina, among others. Yrigoyen is supported by some young people such as Marcelo T. de Alvear and the majority of radical leaders in the province of Buenos Aires, whose provincial committee was led by Yrigoyen himself.





In 1896, Aristóbulo Del Valle died and Leandro Alem, plunged into a deep depression affected by successive political defeats, a failed love relationship and the deep internal division of radicalism, committed suicide. At that time the two radical groups tried to unify again in the face of the death of the two top leaders of the party. But the union did not last long and in 1897 the separation occurred again.




The former Reds, now led by Bernardo de Irigoyen and called radical coalitionists or Bernardists, after Alem's suicide, try to reach an agreement with General Bartolomé Miter and the National Civic Union to confront the Roquismo in the presidential and Buenos Aires elections of 1898. The agreement included the formation of a mixed formula for the presidency of the Nation, headed by the radical Bernardo de Irigoyen, and the same, but headed by the engineer Emilio Mitre, leader of the UCN, for the governorship of the province of Buenos Aires.




This agreement was known as the "parallel policy" and laid the seed for a future reunification of the Civic Union, as confirmed in 1890 before the division that occurred the following year between radicals and mitristas, but Yrigoyen and his allies (now known as intransigents or hypolists) refused to accept it and did everything possible to boycott it from their stronghold of the radical committee of the province of Buenos Aires.



In the end the agreement between radicals and Mitristas fell definitively due to Yrigoyen's action of dissolving the Committee of the Radical Civic Union of the province of Buenos Aires, which ended any possibility that the radicalism of the province would accept a Mitrista candidate for the governorship of the province. The fall of the parallel politics paved the way for the second presidency of General Julio Argentino Roca.



Even so, in the province of Buenos Aires, the national autonomists of Pellegrini, the radical coalitionists and the intransigents of Hipólito Yrigoyen managed to negotiate in the Electoral College and managed to establish Bernardo de Irigoyen, leader of the radical coalitionists, as governor of the province together with the intransigent radical Alfredo Demarchi as vice-governor, to snatch the province from the National Civic Union, who had won in the popular vote.




A lo largo de los siguientes años el radicalismo ingresaría en un tumultuoso periodo en el que todas las estructuras partidarias colapsaron y la interna entre coalicionistas e intransigentes nunca se saldo. Durante la gobernación de Bernardo de Irigoyen, los hipolistas fueron sus principales opositores, por lo tanto el gobierno provincial sobrevivió gracias al apoyo de los pellegrinistas y del gobierno nacional de Roca.



By the year 1900, the Bernardista sector of radicalism, which grouped together some of the men who had been closest to Alem, joined the Autonomist Party of the province of Buenos Aires, led by Carlos Pellegrini. The fusion between the Autonomist Party and the Bernardist sector of radicalism eventually resulted in the formation of the United Parties, which brought Marcelino Ugarte to the governorship of Buenos Aires in 1902, with the former radical Adolfo Saldías as its vice-governor.




Towards the first years of the 20th century, the Radical Civic Union had officially ceased to exist. But the survival of radicalism as a political force until the present day was largely the work of Hipólito Yrigoyen and the political circle that accompanied him since the internal party of 1893. At the beginning of 1903, Yrigoyen began to reorganize the Unión Cívica Radical (Radical Civic Union), inviting a political event for July 26 of that year, on the thirteenth anniversary of the Revolución del Parque (Park Revolution).



The event received a great response from the public and was attended by approximately 50,000 people. Yrigoyen was also successful in attracting important figures who had been part of the ranks of radicalism and who at that time were part of other political parties, such as the case of Pedro C. Molina from Córdoba, who was part of the Republican Party, led by Emilio Mitre.




In October 1903, the so-called "Convention of Notables" met in Buenos Aires, made up of more than 300 political leaders from all over the country, whose objective was to elect the presidential candidate who was to replace Julio Argentino Roca in office in 1904.



The Convention of Notables took place in the midst of the strong dispute between Roca and Carlos Pellegrini, which had been taking place since the breakdown of relations between the two in 1901 after a disagreement over a project to unify the external debt, which divided the Autonomist Party. National in two sectors: rockers and pellegrinistas.




Before the convention, Pellegrini was emerging as the main candidate for the presidency of the Nation but during its development, Roca managed to block Pellegrini's candidacy. For this reason, Pellegrini publicly accused Roca of destroying the National Autonomist Party. The rupture between the two, which was hinted at during Roca's second presidency, ended up materializing and Pellegrini founded the Autonomist Party. For this reason, Pellegrini and his supporters abandoned the convention, as did the political core led by Bernardo de Irigoyen.


Due to the break with Pellegrini and part of the interior leadership, Roca had to make an agreement with Marcelino Ugarte, governor of Buenos Aires, who imposed the name of Manuel Quintana as a presidential candidate to try to position himself as his successor. The winner of the Convention of Notables was Marcelino Ugarte who was able to impose Manuel Quintana, who was a man "stranger to the parties" and who had been a political rival of Roca in 1893/1894 when he served as strong man of the Luis Sáenz government Peña, as president and accepted José Figueroa Alcorta from Córdoba, a name promoted by the interior leaders associated with the ruling party, as vice president.




In February 1904, Yrigoyen organized a party convention, the first since the 1897 convention that debated parallel politics. However, almost no former Alemnista or Bernardista returned to the party ranks and the radicalism that was reorganized was made up almost exclusively of those men who were part of the old Buenos Aires radical group of Yrigoyen.



The reconstruction of the UCR carried out by Yrigoyen showed a series of distinctive features. To reunite the party, the Buenos Aires leader resorted to the sacred symbols of radicalism: the figure of Alem, the revolution of July 1890, the party conventions and the revolution. Yrigoyen knew how to use party symbols to give his organization an image of continuity with the original group..





Obviously it was not mentioned that during the 1890s Yrigoyen's political sector had behaved as an organization independent of the party branch, that its leader had maintained a tense relationship with Alem, that Yrigoyen's participation in the Parque revolution of 1890 had had been a minor, who was suspected of having refused to cooperate in the armed uprisings planned by Alem after 1893, and of having defied the authority of the last party convention in 1897.





While other sectors of the old radicalism had dispersed and merged into different political parties, Yrigoyen presented himself as the legitimate heir of the Radical Civic Union, loyal to its founding objectives and strategies. The new radical organization demonstrated against the omnipotence of the PAN, against its economic policy, against corruption, and against the absence of guarantees for clean elections.




The UCR partly resumed its old language and style, although it did so in a context markedly different from the previous one and with some of its own particularities. In the first decade of the 20th century, the PAN was in complete decline and completely divided, the economy returned to its high growth rates and new political parties, such as the Socialist and the Republican, experienced the direct benefits of electoral competition.




On February 29, 1904, the newly reorganized National Committee of the Radical Civic Union declared the party's electoral abstention in the presidential and legislative elections of 1904. But while they declared their electoral abstention for the 1904 elections, its leaders conspired. Hipólito Yrigoyen had toured the country convincing and engaging hundreds of radical militants and young Army officers, and had even formed a revolutionary junta that he led, supported by José Camilo Crotto, Delfor del Valle and Ramón Gómez.



The initial objective was for this revolutionary movement to break out on September 10, 1904, during the government of Julio Roca. But the revolution had to be postponed. The government was suspicious and had taken some preventive measures. Yrigoyen, the only one who knew the entire revolutionary plot, decided to wait for the right moment.




On October 12, 1904, Roca completed his presidential term and handed over the presidency to his successor, Manuel Quintana. For his part, Yrigoyen explained to his coreligionists that it was not a revolution against a person but against "the Regime", so it mattered little if it started earlier or later.



Finally, in the early morning of February 4, 1905, the civil-military revolutionary movement, which had been preparing since the beginning of 1904 by the leaders of the Radical Civic Union and allies within the Army, began in the Federal Capital, Bahía Blanca. , Mendoza, Córdoba, Rosario and Santa Fé.



In the Federal Capital, the key element of the plot was the seizure of the Arsenal, from where weapons would be distributed to groups of radical militants. However, an infidelity allowed the government to learn of the revolutionary plan. General Carlos Smith, chief of the General Staff, in collaboration with Colonel Rosendo Fraga, chief of police of the Federal Capital, anticipated and became strong in the Arsenal, preventing the uprising of the neighboring 1st and 10th infantry regiments. In this way he prevented groups of civilian revolutionaries from being provided with weapons. Without those weapons the plan was destined to fail. Although in the previous days the radical leader had warned of the possibility of failure, it was already too late to give the counter-order. However, what happened at the Arsenal was not enough to stop hundreds of radical militants who, throughout the early hours of the morning, attacked numerous police stations in the city.



The government of President Manuel Quintana, who knew of the revolutionary plans, reacted with quick measures: he declared a state of siege throughout the country for the next ninety days, and established press censorship. The police, loyal to the national government, raided dozens of buildings in search of revolutionaries. Only some troops from the 9th Infantry Regiment marched towards Buenos Aires from Campo de Mayo, but shortly afterward they dispersed. Loyal troops and police soon recovered the police stations taken by surprise and the revolutionary cantons. At noon on February 4, the revolution in the Federal Capital had been completely defeated.




But the same was not happening in other parts of the country. The uprising had been successful in Mendoza, Córdoba and Bahía Blanca, where civilians had had the support of several military regiments. In Mendoza, the entire military garrison joined the uprising along with a mountain artillery regiment from San Juan. These troops provided weapons to civilians who identified themselves with their white berets. The revolutionaries attacked the capital of Mendoza, took 300,000 pesos from Banco Nación and attacked the barracks defended by Lieutenant Basilio Pertiné. The Mendoza government and some soldiers tried to resist in the Government House but laid down their arms. José Néstor Lencinas, head of the Revolutionary Junta, formed a provisional government after overthrowing the constitutional governor Carlos Galigniana Segura.




In Córdoba, the military troops under the command of Colonel Daniel Fernández were mobilized from the early hours of dawn and began to move after a speech by Colonel Fernández, in which he said: “Soldiers: we are going to carry out a transcendental crusade! For the Argentina that is close to dying, which is the reverse of Caseros and Pavón”!





The rebel military troops took over the Police Headquarters, took over the capital city and clashed with troops loyal to Governor Olmos, led by Colonel Gregorio Vélez. The hostilities lasted until noon and left several dead on both sides. Once the combats were over, they overthrew the government of José Vicente Olmos to impose a provisional government under the command of Colonel Daniel Fernández, accompanied by Abraham Molina and Aníbal Pérez del Viso as ministers. The proclamation spread in Córdoba sets the tone of the radical revolutionaries: "... the day has come when the opprobrious regime that has dominated the country for 30 years, covering it with ignominy before friends and strangers, ends."



In Córdoba, the radical revolutionaries took hostage Governor Olmos, Vice President José Figueroa Alcorta, who by chance was in Córdoba, Deputy Julio Roca, son of General Julio Argentino Roca, Francisco J. Beazley, who was returning from acting as intervener in San Luis, to Felipe Yofre, former Minister of the Interior during Roca's presidency, to Baron Antonio Demarchi, son-in-law of former President Roca, among other officials and political leaders of the opposition.



The radicals also headed towards the La Paz ranch, owned by Julio Argentino Roca, to try to arrest the former president, but Roca, who had been warned that the revolutionaries were heading towards his ranch, managed to escape from being taken prisoner and headed to the neighboring province of Santiago del Estero.



In Rosario the radical military troops marched from San Lorenzo towards Rosario, where civilian groups had taken over the Argentine Central Railway station. In Rosario, intense fighting also took place in the Arroyito area. However, once the failure of the revolution in Buenos Aires was known, the rebellious troops returned to their barracks, and abandoned the civilians to their fate.



The rebellious troops in Bahía Blanca and other cities in the interior had no perspective, nor did they find an echo in the town. President Manuel Quintana employed the same tactic used in 1893 to quell the radical movement; The state of siege became martial law. Despite the initial successes in Córdoba and Mendoza, the national government kept the situation under control and sent troops from different parts of the country to reduce the revolutionary centers.



The revolutionary attempt had not prospered in the other provinces, and the Córdoba radicals would be left alone in the fight. In search of a way out of the difficult situation, the revolutionary minister Aníbal Pérez del Viso took Vice President Figueroa Alcorta to the telegraph offices, where he made him establish communication with President Manuel Quintana. Once this was done, Pérez del Viso took the place of Figueroa Alcorta and began to propose different solutions, which obviously protected the insurgents. The revolutionaries even asked President Quintana for his resignation in exchange for the life of Vice President Figueroa Alcorta, however the president did not give in and the threat was not carried out.



As the powerful columns led by Generals Lorenzo Winter and Ignacio Fotheringham approached, the revolutionaries in Córdoba and Mendoza began to disperse. Finally the Radical Revolutionary Junta decided to lay down their arms to avoid more bloodshed. On February 8, there were no revolutionary centers left in the entire Republic. Immediately, the government of President Manuel Quintana arrested and ordered the rebels to be prosecuted, who were sentenced to up to 8 years in prison and sent to the Ushuaia prison. Many others went into exile in Chile or Uruguay. In the case of the military, those who joined the uprising lost their careers.



The repression was carried out against the radical revolutionaries and simultaneously against the labor movement, the socialists and their organizations, their press, etc., although they had had no connection with the February 4 movement. Hundreds of union members were arrested, the socialist and anarchist press was banned, the offices of the newspapers La Vanguardia and La Protesta, among others, were raided, and union offices were closed.



After the events of February, Quintana addressed Congress and said in this regard: "When I received the government, I knew of the conspiracy that was being hatched in the Army and that is why I directed that incitement to remain a stranger to the agitations of politics by invoking "at the same time the example of their ancestors and the glory of their weapons. A part of the junior officers did not want to listen to me and preferred to embark on an adventure that does not excuse inexperience in the face of the inflexible duties of the soldier."




After the defeat of the revolution, Yrigoyen went underground since he was wanted by the national authorities and for months there was no news about his whereabouts. Finally, on May 19, he appeared before Justice to assume his responsibility as the maximum head of the Revolutionary Junta.



The revolution was defeated, but it would unleash a current of institutional change within the ruling party that could no longer be stopped. The National Autonomist Party had divided, and both Carlos Pellegrini and Roque Sáenz Peña, main leaders of the new Autonomist Party, founded in 1903, understood the need to make profound institutional changes if the growing social and political conflict was to be contained.




Although at the moment the hostilities against the national government were still high and on August 11, 1905 there was an attack against Quintana, while he was heading in his carriage to the Government House, a man shot the president several times without being able to do anything. fire. The car continued moving, and the custody agents detained the aggressor, who turned out to be a Catalan worker named Salvador Planas y Virella, an anarchist sympathizer, who acted on his own initiative.



In March 1906, President Manuel Quintana died and was replaced in office by José Figueroa Alcorta, who until then was the vice president of the Nation and was politically inclined towards Pellegrinism. In June 1906, Figueroa Alcorta and Pellegrini promoted a Law of Oblivion, to offer a general amnesty to all radical participants in the revolution of the previous year, exiled in Uruguay and Chile or who were in hiding or prisoners.



In the years that followed, radicalism grew in support among sectors of the incipient middle class of the Federal Capital and the interior, especially among those young professionals, children of immigrants. The social composition of the radical leadership also changed with respect to that of the 1890s. The majority of its leaders seemed to come mainly from families who had arrived in the country recently and who had had little or no participation in politics. In comparison to that after the Park Revolution, where its leaders came from traditional families of the country.



The political system was also changing in those years, when a sector of the ruling class decided to open up and transform the rules of the political game. The reformists led by President Figueroa Alcorta believed in the need to promote an electoral reform that would establish a truly representative government. And the electoral reform finally arrived, in 1912, at the hands of Roque Sáenz Peña. Four years later, on October 12, 1916, the leader of the 1905 revolution, Hipólito Yrigoyen, took office as president of the Nation.

Argentine Aviation Army: The Grumman OV-1C/D AE-021


     

The Grumman OV-1C/D AE-021

In conjunction with a re-equipment program of the Argentine Army Aviation, as a result of the lessons left by the war over the Malvinas Islands, the Mohawk SDARM (Weapons System) was gradually withdrawn from the US ARMY, giving the possibility of acquiring a batch of 23 aircraft of the OV-1C and D type to this country in order to supply this weapon.

Thus, in 1992, the affected cells in the United States began to be selected, for which purpose a group of troops was commissioned with the then Major Horacio Sabin Paz in charge.

Of these aircraft, the first to arrive in the country would be those registered AE-020 and AE-021, the first of which had (and has) dual command.



The aircraft that concerns us today is the one that carried Bu/No 68-15932, which saw the light for the first time when it left the Grumman factory in January 1969, its original standard being that of OV-1C, converted to the D model in December 1974, carrying the Motorola AN/APS 94 SLAR radar, which was removed before its delivery to our army.

After a brief stint at NASA in 1983, he was sent to the 224Th MI BN, where he remained stored for a long period, his last Criew Chief in the US being Lt (Lieutenant) Mathewson.



He was permanently discharged in the United States in April 1993, despite which his administrative discharge was some time earlier, since his shipment by ferry flight to our country ended in December 1992, with a North American crew.



It enters in service in the "Escuadrón de Aviación Exploración y Reconocimiento 601" in December 1992, a unit in which he remained during his brief career in our country, being the first OV-1 with simple command to arrive in the country (the AE- 020 had it originally).



In 1999 he was transferred to reserve status in the "Batallón de Abastecimiento y Mantenimiento de Aeronaves 601", and his discharge was decided that same year. Finally, it was destined as a monument, for which it was thoroughly cannibalized, preserving the engines and propellers, remaining since August 1999 in the "Historical Museum of the Argentine Army", located in the town of Ciudadela in fair condition. (Carlos Pellegrini and Father Elizalde Ciudadela)




The AE-021 in NASA 

The OV-1D Mohawk number 67-15932 was used in 1983 as a test bed for tests carried out jointly between NASA and the US Army within the framework of the USAAEFA program in order to develop and evaluate a new loss warning system. , and dangerous excess or decrease in speed. The system designed by NASA presented both the indicated speed and the stall speed in the same integrated instrument, it also incorporated a voice synthesizer that produced a verbal alert that indicated possible risk situations. Visual information of an imminent stall was presented to the pilot as a cursor or pointer located on the conventional speedometer.
The indicated speed and the stall speed were computed in real time, taking various parameters of the airplane's aerodynamics.
When the system was ready, it was installed on the Mohawk and tested for less than 20 flight hours, enough time to calibrate the system and determine the aircraft's loss coefficients. Then these data obtained during the tests were uploaded into the system software and another 10 hours of flight were carried out where the device was satisfactorily evaluated. All flights were carried out by US Army pilots, not from the Dryden base where NASA normally conducts its tests but from a US Army base.

Argentina-Chile Naval Race: 1890-1905 (2/13)

Naval Race between Argentina and Chile, 1890-1905

Part 1 || Part 2 || Part 3 || Part 4

What was happening on the other side of the Cordillera?


As in all countries that wanted to emancipate themselves from Spanish power, at the beginning of the War of Independence, Chile did not have any warships, much less suitable crews for them. Given the above, the territorial defense plan did not involve a political policy at all. naval but to defeat the Spanish army on land 1.

Viceroy Abascal highlighted the Warren Frigates in Valparaíso, with the purpose of blocking the port, in order to boycott the insurgents' trade. It should be noted that Chile had declared free trade in its ports for all ships in the world.

José Miguel Carrera wrote to Francisco de La Lastra (governor of Valparaíso), with the aim of putting some ships under arms and lifting the blockade. This request, at the cost of efforts (popular spending, credits, etc.), managed to equip two named ships. like Perla and Potrillo 2, part of the weapons used were from a Portuguese merchant ship, which were seized by the government of Chile 3.

It was thought that once the blockade was broken, the “Chilean Fleet” could join the Argentine corsairs and harass Callao, but this did not happen, once both ships set sail, the Perla joined the Warren and both They attack Potrillo, thus ending the attempts to provide Chile with a squadron, during the Patria Vieja, the above happened on May 2, 1813.

Towards 1813 the United States and England were at war, given the above, the United States sent the frigate Essex to the South Pacific with the mission of harassing the English whalers that operated in this water. Thanks to this, Chile's trade benefited due to that the Essex's prizes were traded in Valparaíso, a situation that ended a year later when the Essex was captured by an English fleet 4.

Thanks to the Argentine privateers, the transportation of cargo from the Viceroyalty of Peru to Chile suffered setbacks, which hindered the military deployments of the Governor of Chile Marco Del Pont. In this way, added to Rodríguez's actions on land, it was possible for the Spanish army to It will be dispersed throughout the territory, facilitating the task of crossing the Andes to San Martín 5.

After the triumph of the Andes Army in Chacabuco, thanks to a stroke of audacity, the then Argentine Ensign Isidoro Suárez, captured the Spanish brig Águila 6 in Valparaíso, being incorporated as the first unit into the nascent Chilean navy, and was armed with 16 cannons and placed in the hands of the Irishman Raimundo Morris rescued the patriotic prisoners imprisoned on Juan Fernández Island. On January 16, 1818, O'Higgins and Minister Zenteno promulgated the decree allowing the promotion of roe deer patents 7.

After the patriotic triumph in the battle of Chacabuco, San Martín as commander in chief of the army of the Andes and O'Higgins as supreme director of Chile together with his minister of war and navy José Ignacio Zenteno dedicated themselves to the task of creating an navy With the objective of disputing the sea with the Spanish crown, for this purpose emissaries were sent abroad and ships and other equipment were acquired. The ships acquired were the Navío San Martín (64 guns), Frigate Lautaro (46 guns), Corvette Chacabuco ( 20 guns), Brigantín Araucano (16 guns), with these ships the capture of the frigate María Isabel and the other transports was carried out, this happened on October 28, 1818 8.

At the end of 1818, Thomas A. Cochrane, a Scot, arrived in Valparaíso to take charge of the nascent squadron. I will not detail the naval actions of this period given its length and because it is not relevant in this part of the forum.

The Chilean squadron then consisted of nine warships; but on August 10, the brig Pueyrredón was dispatched in charge of Captain Don Guillermo Prunier to take the most complicated individuals in the April conspiracy to the coast of New Granada, and the corvette Chacabuco was destined to remain in Valparaíso, under the command of Captain Juan José Tortel. The ships that were on the expedition were the following 9:


Almirante O 'Higgins Frigate

Cannons: 50
Crew: 516
Commander: Tomás Crosby


San Martín Ship

Cannons: 64
Crew: 492
Commander: Guillermo Wilkinson


Frigate Lautaro

Cannons: 50
Crew: 353
Commander: Martín Jorge Guise


Independencia Corvette

Cannons: 28
Crew: 256
Commander: Roberto Forster

Araucano Brigantine

Cannons: 16
Crew: 106
Commander: Tomás Carter


Brig Galvarino

Cannons: 18
Crew: 114
Commander: Juan Spry

Schooner Moctezuma

Cannons: 7
Crew: 87
Commander: Juan Esmonds


 
Cochrane left Chile in January 1823 and the ships of the squadron were demobilized from service. To face the Chiloé campaigns he found it necessary to hastily arm the ships and when Chiloé fell into the hands of Chile (beginning of 1826, last Spanish redoubt in America), the entire squadron was declared disarmed.

Given the poverty of the national treasury, in April 1826, the frigate María Isabel Maria Isabel (O'Higgins) and the corvettes Independencia and Chacabuco were put up for sale, being acquired by Argentina due to the urgency of the war they were fighting with Brazil over the Banda Oriental (Cisplatina), only the Chacabuco arrived in Buenos Aires but its condition was poor, the others sank in Talcahuano (Independencia), and Cape Horn (Maria Isabel) 10.

It should be noted that given the tremendous economic efforts for Chile to face the liberation expedition of Peru, the maintenance of the ships was deficient and the sailors were unpaid. By mid-1826, the squadron was disarmed and the naval school closed, leaving only the brig Aquiles in operational status.

The navy would only emerge again in 1836 before the war against the Peru-Bolivian confederation (1836-1839), when it began it only had the Brig Aquiles and the Schooner Colo Colo, then this fleet was increased by 5 more ships, given the capture of the boat Santa Cruz, the brig Arequipeño and the schooner Peruviana in Callao, plus the capture of General Freire of the frigate Monteagudo, brig Orbegoso 11.

Once the conflict was over, the squad again declared disarmament, maintaining only a few units for the needs of the service. In 1843, President General Manuel Bulnes Prieto (Who directed the 1838 campaign against the Peru-Bolivia confederation), ordered Captain Juan Guillermos to took possession of the Strait of Magellan, at that time Juan Guillermos was maritime governor of Chiloé, in the city of Ancud, he dedicated himself to the construction of a schooner (which would be named Ancud), to carry out the requested undertaking.

It is not the topic of the present to address the border disputes between Chile and Argentina but, as the topic indicates, to address the arms race between Chile and Argentina between the 19th century until the May Pacts, the above is only due to a very brief historical review of the navies of both countries.

Between the years 1840 and 1863, the Chilean navy experienced a great decline, a powerful ship was commissioned from France but it was built with poor materials so its useful life was short (Chile Frigate).

During that period there were not enough funds to order the construction of steamships. Given the lack, the decision was made to build them in Chile precisely in the Constitución and Valparaíso shipyards. In 1852, the corvette Esmeralda was commissioned in England (which was sunk in the Naval Battle). of Iquique in 1879), in this way at the beginning of the war with Spain (1864-1866), Chile only had the Esmeralda and the Vapor Maipú (strictly speaking, only the Esmeralda was a warship), in the face of this contingency and after the Chinchas Islands were taken in 1863, it was decided to commission the acquisition of the corvettes Chacabuco and O'Higgins, in 1865 the schooner Covadonga was captured and in 1866 two more corvettes were acquired (Abtao and Pampero), only the first of them arriving. , and Benjamín Vicuña Mackenna acquires in the United States 4 wheeled steamers called Poncas (Ñuble), Isabella (Concepción), Shaw Nork (Arauco) and Cheroke (Ancud) all in poor condition 12, this due to the failure of the negotiations for the acquisition of Dundemberg 13.

With the exception of the Abtao, none of these ships arrived for the war. At the end of the war, Chile had 9 naval units, viz.

Corvettes: Esmeralda, Abtao, Chacabuco and O`Higgins (these arrived in 1868).
Schooner: Virgin of Covadonga.
Steamers: Ñuble, Concepción, Arauco and Ancud.

The 4 steamers were lost in accidents or storms, in which their poor integrity was the fundamental cause.

So far I leave this brief review of the navy since its creation. From here on, a process of arms race between the republics of Chile and Argentina begins slowly but steadily, which would end momentarily with the pacts of May 1902.

Malvinas: The Torpedo-bomber Variant of the IA-58 Pucará

The "Torpedo-bomber" IA-58 Pucará




In mid-May 1982, during the South Atlantic Conflict, the Strategic Air Command decided to carry out a series of test flights aimed at operationalizing the IA-58 Pucará system with the North American Mk 13 torpedo, practically deprogrammed by the Argentine Navy.

This torpedo, which had been produced between 1943 and 1945, was of a rather robust design and was designed for use from boats and airplanes. The Argentine Navy used it for several years, launching it at a speed of 165 km/h from Consolidated PBY-5A Catalina aircraft.

The person responsible for this project began at the Puerto Belgrano Naval Base. The Navy provided a sufficient number of torpedoes to which fastening elements were placed and the torpedo's own systems and mechanisms were put into service again, after a long time.

On May 21, 1982, the IA-58 Pucará AX-04 landed at the Comandante Espora Aeronaval Base, equipped with a video camera to record the moment the torpedo was launched, which would be placed in the central station of the plane.

On May 22, the first launch of the Mk 13 torpedo with an exercise head was carried out. The launch area selected by the Navy was located 65 kilometers from Puerto Belgrano. On the same day, a second launch was carried out. In its final run, the plane adopted a dive angle of 20º, a speed of 555 km/h and at an altitude of 100 meters it released the torpedo, which was destroyed on impact. The same thing happened the next day, although the launch was carried out with a dive angle of 45 degrees, 465 km/h and at a height of approximately 200 meters.

Tests showed that something was wrong with the torpedo after it was launched from an airplane. The Navy did not have operations manuals available for its aerial use, there was only information that the torpedo had to enter the water at an approximate angle of 20 degrees. If this angle was less, it would rebound, damaging the control and propulsion mechanisms, and if the angle was greater, there was a risk that the torpedo would become "stuck" to the bottom.

After making countless consultations with personnel who had been assigned to the torpedo workshop, the Mk 13 was fitted with an aerodynamic brake in the nose and a biplane horizontal stabilizer in the tail, additions that would be destroyed when the torpedo entered the water.

With these additions, on May 24, the first successful launches were carried out in the San José Gulf, Trelew. They were carried out from straight and level flight and at a height of 15 meters, determining the desired speed at 360 km/h, since at higher speeds the torpedo would collide with the seabed.

Seven tests were carried out, and on June 10, a launch with an explosive head was carried out in an area of deeper waters with a cliffed coast, located north of Puerto Santa Cruz, although the depth was not sufficient for the 465 km/h used, now by the Pucará A-566, which replaced the AX-04 in this launch.

It was decided to make a last attempt on June 14 in the vicinity of Pingüino Island, near Puerto Deseado, selected for maximum depth and steep component of the coast, setting the final speed at 360 km/h, but this operation was canceled. definitely, while preparations for the launch were being made.

It is noteworthy that simultaneously with this project, studies were also carried out to drop, from the Pucará plane, Mk 12 anti-ship mines, planned to mine the San Carlos Strait in the Malvinas Islands. However, the hitching tests on the plane were not passed.

Argentine Navy: Navy Colonel Juan Bautista Thorne

Navy Colonel Juan Bautista THORNE



The Thornes had ancient recorded origins in Europe and North America. One of the Thornes was among the first to settle on American soil; Enrique, the father of Juan Bautista, a naval engineer by profession as a ship captain, fought for the independence of the United States. Juan Bautista, son of Margarita Brayer and Enrique, was born on March 8, 1807.

He enlisted in the Argentine Navy that, under the command of Brown, was preparing Rivadavia to defeat the power of the Brazilian empire in the waters of the Plata. Discharged from the squadron on June 1, 1826, he went on to review with the rank of Midshipman and pilot on the warship Congreso, placed under the command of Fournier, whom the Brazilian newspapers called "Exterminator Ray." Shortly afterwards, at the beginning of 1827, he was assigned to the brig Chacabuco, which under the command of Santiago J. Bynnon, later second commander of the Argentine fleet, came from Chile to join the original fleet and was later to fight the heroic defense of Patagones.

That March 7, 1827, in front of the river bar that the enemy ships had tried to cross and the coastal battery that Admiral Pinto Guedes had ordered to be destroyed, a glorious action would be fought for Argentine naval weapons. Commander Bynnon, with the Chacabuco and the ships of his squadron, at dusk set out to board the Brazilian ships; He took the Escudeiro, fell on the Constança, and the brave Thorne jumped first onto the deck of the Itaparica to triumphantly raise the Argentine flag. The action earned him command of the brig Patagones, armed with two cannons and an 18-gun revolving wheel, which on December 23, 1827 engaged in combat with the sixteen-gun Brazilian brig Pedro II and was surrendered, while Thorne was wounded. shrapnel was taken prisoner and taken to the capital of the empire, from where he returned when peace was made with Brazil in 1828.

Returning to service, he joined the brig Balcarce, which at the beginning of the war had been Brown's flagship. While there, he received the rank of captain on February 23, 1830, and then obtained several assignments: in February 1831, He was transferred to the schooner Martín García, in September 1832 he reached command of the brig Republicano with which he carried out the Entre Ríos campaign, upon whose return he was promoted to Sergeant Major. In the schooner Margarita he undertook the campaign to the Colorado River in 1833, and in order to assist in the expedition of Don Juan Manuel de Rosas, he explored said river in the schooner Sofía. The following year he was part of the exploration cruises to the southern regions, and alternately commanded the schooner brig San Martín, the brig Republicano and the lugger Patriota.

Designated Commander of the Sarandí, he was entrusted with the mission of assisting the defense of Martín García Island, a task he completed to be transferred to command of the land artillery of said island, where on October 12, 1838, with a hundred braves Gauchos led by Gerónimo Costa sold their lives dearly in the single combat they fought against the blocking French squad. Thorne fought heroically and remembering the episode many years later he used to say:
"My grave should be Martín García, because there I fought defenseless and
even with anger when seeing my helplessness..."

Difficult days ensued. The fight between federalists and unitarians became bitter and persistent. Thorne, a foreigner, was unable to discern any slogans in his chosen homeland other than subordination and discipline. Destined to land service, he carried out the Entre Ríos campaign with Echagüe in 1839. He was in many combats, received numerous wounds, and in old age he could locate under the skin, in different parts of the body, the leads of the bullets received. When on April 15, 1841, with the rank of lieutenant colonel, he returned to place himself under the orders of Admiral Brown, he had to note in his service record that he had attended the war actions of Cagancha, Pago Largo, Don Cristóbal, Caaguazú , Yerúa, Sauce Grande and Punta Diamante.


Appointed commander of the brig General Belgrano in June 1842, he accompanied Brown in the campaign against Garibaldi; The Admiral continued going up the Paraná with the purpose of defeating the enemy, while Thorne had the mission of guarding the entry of reinforcements through the Plata, for which he had the second division of the fleet, made up of the 25 de Mayo and the General San Martín.

Assigned to the river defense service, on August 17, 1845 he was appointed commander of one of the three batteries located in the Vuelta de Obligado, in which position, a few months later, on November 20 of the same year he maintained with high courage and a tough fight against the blocking squad would be bizarre. The action having begun in the middle of the morning, Thorne's guns grumbled until late in the afternoon, and only ceased when the bullets had run out.

The brave opponent of the Anglo-French squadron obtained, perhaps in recognition of his previous services, the designation of Commander in Chief of the coasts of Paraná. From this position he directed the fortification of the Quebracho coast and fought some skirmishes against the blockading squad, in one of which he was wounded in the shoulder. Commander of the schooner Pontón in 1849, Caseros found him on February 3, 1852, commanding the boat Julio from which he descended to soon begin the path of political banning.

Erased from the military list he was forced to earn a living. Sea dog, as captain of a low-freight merchant ship, made many trips to India and worked in various tasks as a naval expert, until calmer spirits, the just and patriotic law of September 24, 1868, ended in general with the material sufferings and the moral agony of the brave combatants of the independence campaigns and the war against the empire of Brazil. The state remembered the helpless octogenarians who had founded the Republic and reparations were made.

Retired with the rank of colonel to the peace of the home, which he had formed by marrying María Abad. Thorne's existence came to an end at the age of seventy-eight, he suddenly fell ill and left life in his house in Tucumán Street, on August 1, 1885. His mortal remains were buried in the Dissidents cemetery. Twenty-two years later, in March 1907, on the centenary of his birth, a popular tribute commission honored him, and Dr. Pedro J. Coronado recalled his memory to say, among other things: "A century has passed since he was born on earth. "our hero misses, and his figure grows out of the cloud of passions and partisan mirage. Thorne chose his country and his destiny." The newspaper La Nación also expressed: "History owes him an illuminated page of heroism. Today, he belongs without hesitation to immortality."
