1955 Guerra Civil. La Revolucion Libertadora y la caída de Perón
Buenos Aires, early morning of September 21, 1955: Army tanks destroy the headquarters of the Nationalist Liberation Alliance
By the evening of September 20, 1955, it was evident that the Peronist regime was on the verge of collapse. However, concerns remained about potential retaliation, not so much from the Armed Forces but from loyalist unions and party militias. Anticipating such a response, the Ministry of the Navy was heavily fortified around 8:00 PM due to rumors of an imminent attack by Peronist militias. Rebel forces prepared for a potential evacuation via naval routes, deploying the Ushuaia transport, the Mandubí tug, and a towed infantry landing craft.
Rebel forces consolidated their positions, arming troops with light weapons, machine guns, and grenades to repel any attack. Troops took defensive positions near the Naval Workshop and the Hotel of Immigrants, awaiting orders to board, while maintaining a heightened state of alert.
Meanwhile, the Nationalist Liberation Alliance, a steadfast Peronist stronghold, was mobilizing for combat. Despite the political chaos, the Alliance, led by Guillermo Patricio Kelly, demonstrated unwavering loyalty. Their headquarters was converted into a makeshift fortress, with the ground floor serving as a field hospital and the upper floors used to destroy compromising documents. Kelly, having secured weapons directly from Perón’s aides, was resolute in fulfilling the battle cry: “La vida por Perón” (Life for Perón).
Rumors of unions distributing arms to workers prompted the Military Junta to summon union leader Hugo Di Pietro for clarification. Di Pietro denied the allegations and invited inspections to confirm the union’s neutrality. In response, the Junta issued appeals to union, party, and religious leaders to prevent violence and restore order.
Simultaneously, military leaders moved decisively. General Raúl Tassi took control of the Ministry of Communications, ensuring the resumption of national telecommunications and confiscating weapons allegedly intended for distribution among workers.
As the day ended, reports reached Tassi that the Nationalist Alliance had rejected ceasefire terms and was preparing for battle. General Audelino Bergallo, in command of Buenos Aires, issued an unambiguous order: “Destroy them with cannon fire!” Preparations began for a full assault on the Alliance’s headquarters.
A military detachment, led by Captain Guillermo Genta and Cadet Heriberto Justo Auel, equipped a truck with machine guns and advanced towards the Alliance’s stronghold. Amid torrential rain and deserted streets, they arrived at the location, supported by tanks poised to fire. Meanwhile, Kelly, heavily armed, left the building to negotiate directly with military officials at the Ministry of the Army.
Despite calls for surrender to avoid bloodshed, the defiant Alliance remained entrenched, ready to fight to the bitter end for Perón. These tense moments underscored the depth of division within Argentina as the regime crumbled.
In the early hours of September 21, 1955, tensions reached their breaking point in Buenos Aires. Guillermo Patricio Kelly, the fiery leader of the Nationalist Liberation Alliance, stormed out into the rain-soaked streets of Reconquista, ignoring the tanks and cavalry company positioned for an imminent attack. Consumed by fury after being told by Major Renner that Perón was leaving to avoid bloodshed, Kelly fumed: “What do I tell my men when they see their leader escape?” His defiance was evident, but fate had other plans.
As Kelly marched back toward the Alliance headquarters, he was stopped in his tracks by armed soldiers who ordered him to surrender. Disarmed and detained, Kelly was sent to police custody. Meanwhile, the situation at the Alliance’s stronghold deteriorated rapidly.
At precisely 1:14 AM, the 600 militants inside the building—who had vowed to die for Perón—opened fire on Army forces from windows and rooftops. The Army responded with machine-gun fire and tear gas, but the militants held their ground, displaying extraordinary fanaticism and resolve. The Army escalated the assault, with tanks unleashing a barrage of shells that shook the concrete structure and echoed through the city.
By 2:00 AM, the building was engulfed in flames. A devastating tank shell struck the munitions depot inside, triggering explosions that further destabilized the structure. The surviving militants evacuated, dragging their wounded comrades as the battle raged on. By 2:30 AM, the Alliance headquarters lay in ruins, its collapse symbolizing the fall of a regime marked by violence and repression.
Amid the chaos, two fire brigades arrived to prevent the flames from spreading to nearby buildings, while curious onlookers were kept at bay by law enforcement. The fiery destruction cast a sinister glow over Buenos Aires, marking the end of the Alliance’s defiant stand.
Elsewhere, confusion reigned within the naval forces loyal to the rebels. Believing a counterattack was imminent, Admiral Domingo Aramburu disbanded the Naval Operations Command, allowing his men to act independently. Most boarded the Ushuaia and Manduví, leaving others scattered throughout the city or holding their positions. In the disarray, the ships departed prematurely, abandoning some personnel and failing to secure critical equipment.
The dramatic fall of the Nationalist Liberation Alliance headquarters and the disorganized retreat of naval forces underscored the unraveling of Perón’s remaining loyalist factions. It was a night of fire, defiance, and collapse, sealing the fate of a regime that once dominated Argentina’s political landscape.
ALN Rally During Peronism’s Heyday
A Glimpse of Glory: ALN Rally During Peronism’s Heyday
In the height of Peronism’s reign, the Nationalist Liberation Alliance (ALN) hosted grandiose rallies that epitomized their unwavering loyalty to the regime. The atmosphere buzzed with fervor as flags waved and voices roared in unison, chanting praises for Perón and vows of eternal allegiance. These gatherings showcased not just political solidarity, but a deep-rooted ideological commitment that blended nationalism, populism, and militant resolve.
The ALN, renowned for its fierce rhetoric and combative stance, drew crowds with theatrical displays of patriotism, fiery speeches, and the ever-present symbolism of the Peronist movement. Leaders like Guillermo Patricio Kelly stood at the forefront, rallying supporters with impassioned calls for unity and defiance against perceived enemies of the state. It was a spectacle of both political power and popular devotion, a reflection of the strong grip Perón held over his followers during his golden era.
These moments, rich with enthusiasm and idealism, painted a stark contrast to the chaos and disintegration that would later consume the Alliance. In those days, the ALN stood tall as a pillar of Peronist militancy, confident in its cause and unwavering in its mission to defend the regime at all costs.
On September 21, clashes also broke out in Mar del Plata. That morning, the population spontaneously gathered in the city center, forming large groups of men and women who, despite the rain, marched to the Casa del Pueblo, headquarters of the Socialist Party, to listen to fiery speeches by several opposition representatives, including Roberto Crocitto and Aurelio Principi.
By midday, a naval patrol traveling in a military truck spotted five suspicious individuals walking along the street. When ordered to stop, they ran toward the building at Av. Luro 3137, barricaded themselves inside, and began firing from the third floor.
An intense shootout ensued, with additional troops patrolling the area joining the fray. The confrontation ended when the Peronist militants fled the scene.
In the afternoon, several people arrived to inspect the bullet marks on the building's third and fourth floors and verify rumors of multiple casualties. However, the new authorities provided no official information, and after a couple of hours, the crowd dispersed.
Later that night, around 10:00 PM, another shootout occurred. Groups of Peronist workers, taking cover behind freight wagons at the train station and the dense vegetation of nearby forests, attacked Navy forces guarding the radio stations in the Municipal Sports Park. The exchange of fire lasted until 5:00 AM on September 22 and ended when the unionist groups withdrew, taking several injured comrades with them.
As with the previous day, the Friends of the Local Workers' Union Movement issued a new statement reaffirming their earlier proclamation, urging workers to cooperate with the occupying forces and peacefully continue their daily occupations.
Attendance and dedication to work, despite any attempts to disrupt it, are today our greatest weapon. Ensuring that the city’s economy remains unaffected is our best contribution to maintaining normalcy. At this moment, there are no union leaders in charge, and no one can claim direct representation. However, there must be, in every workplace, a steadfast commitment to work conscientiously.
The Revolution has given true meaning to the slogan “Produce – Produce”, as production now benefits everyone—serving the normal life of the people and the goals of the Liberating Revolution [3].
The final military action of the Liberating Revolution occurred at 5:00 AM, following General Lonardi's decision to break the ceasefire in Córdoba. By that time, Lonardi had been chosen as the future president of the nation, and preparations for forming a new cabinet were underway. However, during the night, suspicious troop movements were observed both in the southern provinces and Córdoba, violating the imposed ceasefire. Perceived as a potential threat to the rebel forces, these maneuvers prompted a demonstration of force to signal the provisional junta of generals that the revolutionaries were prepared for any escalation.
As historian Ruiz Moreno explains, the rebels targeted the Las Higueras airfield in Río Cuarto. The airfield posed a strategic risk, as it could serve as a launch point for loyalist aircraft capable of striking the Aviation School and the provincial capital. Responding to the threat, Commodore Krausse contacted Base Comandante Espora to request an airstrike. The Revolutionary Air Command approved the mission, and Captain Arturo Rial dispatched two Avro Lincoln bombers piloted by Captains Ricardo Rossi and Orlando Jesús Cappellini.
In the early hours of the morning, the bomber crews loaded their aircraft with 200-kilogram bombs and ammunition, performed pre-flight checks, and taxied to the runway. At 2:15 AM, Cappellini's aircraft took off first, followed closely by Rossi's, embarking on a perilous night mission under torrential rain and poor visibility. Years later, Cappellini recalled the challenging conditions: “We took off after 2:00 AM in torrential rain. They provided us with excellent 200-kilogram bombs, which we didn’t have in Córdoba, but they lacked safety fuses.”
By 4:00 AM, the bombers reached their target. However, Cappellini's aircraft faced a critical issue: one of its turbines had detached during acceleration, compromising its stability. Communicating with the control tower at the Aviation School, he reported the malfunction. In response, Captain Hilario Maldonado instructed Cappellini to maintain a circular holding pattern over the target and delay the attack until 6:00 AM.
This marked the Revolution's final offensive—a calculated display of power in the face of lingering resistance, ensuring the success of their cause and the imminent transition of power.

At 6:00 AM, Captain Cappellini received the go-ahead to proceed with the bombing of Río Cuarto Air Base. Reviewing the coordinates on his flight chart, he noted the target was to be struck from an altitude no lower than 700 meters to avoid being hit by their own bomb shrapnel. Concerned about the risk of detection at dawn, Cappellini voiced his objections, but Commodore Krausse responded curtly and decisively: “Proceed with the order.”
Flying in circles until the designated time, the bombers waited for a break in the clouds. As dawn broke, the crossed runways of Las Higueras Airfield became visible through a gap, signaling the moment to strike. The two Avro Lincolns initiated their attack runs, releasing a total of eighteen bombs—ten from Rossi's aircraft and eight from Cappellini’s, though two bombs from the latter failed to release and remained stuck.
The mission complete, the aircraft sharply banked away from the target, enduring violent turbulence caused by the explosions below. Thankfully, none of the shrapnel struck the planes, allowing them to return safely to Base Comandante Espora. Cappellini’s aircraft, however, required a manual release of the jammed bombs, which the onboard mechanic jettisoned into the sea during the return flight. Both bombers landed safely at 8:00 AM, concluding the last aerial operation of the conflict.
The attack caused no casualties, as the airfield had been evacuated prior to the raid. However, it achieved its intended objective: intimidating loyalist forces. Shortly after the strike, General Falconnier called from Villa Reynolds, requesting the suspension of a planned bombing of the Río Cuarto rail station, where two trains carrying tanks had just arrived. He assured the rebels that no troops would be mobilized from that location, signaling the diminishing resistance to the revolution’s advance.
“"The day perfectly matches the occasion—a beautiful sun warms our chilled bodies. How wonderful is the sun's warmth after a freezing night!
Around midday, Alférez C. gathers all group leaders to remind us to keep personnel closer at hand. He, too, notices the gradual relaxation of discipline. Following his instructions, I assemble the group and address them. Fortunately, I find the right words to restore order without resorting to disciplinary measures. They’re all good men.
Finally, good news arrives! We’re informed that a military government has been formed to temporarily lead the Republic. General Lonardi has been named President, Vice Admiral Rojas is the Vice President, and our own Commodore Krausse will serve as Minister of Foreign Affairs.
Although we cannot fully grasp the significance of this moment, the truth is that we have helped change the course of our nation's history. The fall of this regime reaffirms that our people will never accept anything that tarnishes their most cherished legacy: their freedom.
First Lieutenant F. went to confirm the news and returned with happiness written all over his face. He gathered us in a clearing, shared the situation, and congratulated us on our efforts. Within our chests, we felt something I can only describe as the manifestation of that abstract entity we call the Fatherland.
The traditional ‘Subordination and Valor’ was never answered with more emotion.
We then received orders to prepare our gear and begin retreating as soon as possible. Alférez C. shakes our hands and toasts with us to celebrate the success of the movement.
Well, it seems I’m destined to savor every last drop of this Revolution. The entire company is heading back to the school, except for the groups led by ‘Turco,’ ‘Cabezón,’ and myself, tasked with guarding the northern sector of the airstrip. I’m tired—exhausted, really—but I try to lift the spirits of the troops. If I don’t, I don’t know where they’ll find the strength to continue. We are under the orders of First Lieutenant F., who seems deeply troubled by having to stay behind. It’s understandable; he has a wife and children waiting for him.
And so here we are, waiting for the tents to arrive so we can spend the night. When they finally arrive, we set them up, and then dinner is served—a plate of polenta with sauce, which soothes not just our hunger but the gnawing ache of exhaustion.
After posting guards at a nearby crossroads, I lay down. Thankfully, someone left me a cot, which is far more comfortable than the trench. My weary bones couldn’t be happier."
This vivid recounting captures the mix of relief, pride, and fatigue experienced by the soldiers in the final days of the Liberating Revolution, as they reflect on their role in shaping the nation’s future.[6].
