Rio de Janeiro First revolutionary actions The director of the army's Cartridge Factory, colonel João Maria Xavier de Brito Júnior, removed the ammunition for use in the revolt from the nearby Military School of Realengo. The instructor officers armed the students. Nine cadets refused to participate, as well as some officers, being arrested as a result. At 23:50, captain Oton de Oliveira Santos, in charge of the night watch by orders of the school's director, general Eduardo Monteiro de Barros, found colonel Brito with a large number of officers and students in his house, which would normally be closed and with the lights off at this time. Upon being called to enter, Oton fired two shots in the air and ran to the general's house. Monteiro de Barros headed for the Military School, but on the way rebel patrols fired in his direction. He intended to seek reinforcements in Vila Militar, but ended up being arrested. Oton was also captured by the rebels before reaching Vila Militar. Shortly before 01:00, at night, lieutenant Frederico Cristiano Buiz woke up the soldiers of his company, the 7th Company of the 1st Infantry Regiment, and divided them into two platoons. One stayed in front of the barracks, while he led the other to the regimental officers' casino, where captain José Barbosa Monteiro (commander of the company), colonel Sezefredo dos Passos and others were. With his pistol in hand and in front of his armed soldiers, he declared — "The revolution has broken out! I am with the revolution!" Despite being unarmed, Sezefredo dos Passos advanced against Buiz and grabbed his pistol. The other officers also confronted the platoon, and captain Monteiro was killed in the clash. Buiz missed the opportunity, allowing himself to be restrained. Officers who were not yet on the government's side were arrested. For his act of bravery, the regiment's commander was later promoted to general. Marshal Hermes left his hotel at 23:00. He would wait for the 15th Cavalry Regiment near Vila Militar. He went in one of three cars, being intercepted at the
Engenho de Dentro station by a squadron of the 1st Divisional Cavalry Regiment. After abandoning the car, they managed to reach the farm belonging to deputy Mário Hermes, near
Marechal Hermes station. The picket of the 15th Cavalry Regiment arrived, but to arrest the marshal. General Ribeiro da Costa announced his arrest at 06:00 in the morning. Hermes was kept in the battleship
Floriano. His presence in Vila Militar could have had a great impact. At 01:15 or 01:20, Fort Copacabana fired its first shot, targeting the uninhabited island of . The shots were heard throughout the city at dawn and marked the beginning of the uprising. The second shot went in the same direction; the third, to the rock at the base of Fort Vigia, alerting the population, and the fourth, to the 3rd Infantry Regiment, as a protest against the arrest of Hermes da Fonseca. Shots were then expected from the other forts, especially from Santa Cruz and , to mark their participation, but there was only silence.
Defeat of the Military School The Military School of Realengo had 638 students in arms. About a hundred of them stayed at the school to take care of those who did not join the revolt, while another five hundred, or 449, headed to Vila Militar under the leadership of colonel Brito. They were of the four branches, each under its instructional assistant. The cavalry squadron went ahead along the to the Piraquara bridge. The journey began at midnight along the São Pedro de Alcântara road. The expected goal was to join the revolutionaries at Vila Militar, but it was hostile. General was woken up at 02:00 to take over the General Staff of the Army, to which he had been appointed a few days before. The Minister of War, as a civilian, did not command the repression of the uprising, which was the responsibility of the commander of the region. However, according to Carvalho's testimony, general Carneiro da Fontoura was "invisible", resting in his office, while confusion reigned in command, with conflicting information about the revolt. Hearing the artillery on the way, Setembrino went to Vila Militar in person, where he assumed command. Most of the 1st Division remained loyal to the government. Loyalist reinforcements were already on the way: a squadron from the 1st Divisional Cavalry Regiment, heading towards Realengo in reconnaissance, and, towards Méier, a detachment under general
João de Deus Mena Barreto, commander of the 2nd Infantry Brigade. He had the 3rd Military Police Battalion, the 3rd Machine Gun Company, under captain , and other units, without withdrawing many troops from the seat of government. All of Central do Brasil was occupied: a battalion of
Caçadores at Méier station, a battalion of the 2nd Infantry Regiment at
Todos os Santos, and so on. To the south of Vila Militar, a police cavalry squadron guarded the Estrada Real de Santa Cruz. The Catete Palace was protected since 02:00 by a company of infantry from the Naval Battalion, and at 06:00 a company from the 3rd RI and an artillery battery garrisoned the courtyard of the Ministry of War. The first contact was between the Realengo cavalry picket and a patrol of the 15th Independent Cavalry Regiment. At daybreak, the Realengo infantry collided with the barracks of the 1st Engineering Battalion, at the west end of Vila Militar. The revolutionaries took up positions on the Monte Alegre hill, in the locality of Árvore Seca. From there they fought a duel with the 1st Horse Artillery Regiment, which had a 75mm battery near the barracks and two others on the Caixa d'Água hill. 150 men from the School of Sergeants protected the artillery in the direction of Estrada Real de Santa Cruz. The projectiles flew over the roofs of Vila Militar. Captain
Mascarenhas de Morais, of the 2nd Legalist Battery, reported how the rebels' artillery hit near the officers' residences, leading some families to withdraw. General Ribeiro Costa, commander of the 1st Infantry Brigade, led the response from Vila Militar. The Assault Car Company and a
section of the 1st Heavy Machine Gun Company were in reserve. At 10:00 the bitter fight had already lasted four hours. Vila Militar's artillery went from indirect to direct and barrage fire. At that time the loyalists started an enveloping movement. In the testimony of Colonel Xavier de Brito, a new element of loyalist infantry was seen heading towards the school to bypass it from the left flank. According to
O Paiz, the maneuver was behind Monte Alegre, led by colonel Nestor Sezefredo, with the 1st Infantry Regiment, a battalion of the 2nd and a squadron of the 1st Divisional Cavalry Regiment as a flank guard. Colonel Brito assembled his General Staff. There was no chance of victory, and he needed to save the cadets' lives. In Cascadura, more loyalists were waiting. Thus, the revolutionaries raised the white flag and returned to the school. The arrested officers and students were released. The result was one dead and several wounded, among the rebels, and two dead and five wounded, among the loyalists. After 12:00 or 14:00 a squadron of loyalist cavalry, under captain , entered the school without resistance. Later, it was replaced by a battalion from Vila Militar. Colonel Brito and the instructors and other officers were arrested.
Siege of Fort Copacabana At dawn at Fort Copacabana, the revolutionaries, at first without information, were waiting for news of their victory. Loyalist infantry remained nearby, and colonel was appointed commander of the attacking force. The infantry stayed in the Novo and tunnels, and the artillery, in the mountains in the region of the tunnels in Vila Rica and
Leme. The detachment consisted of a cavalry squadron (for reconnaissance and liaisons), a battalion of the 3rd Infantry Regiment and two companies, a battalion of
Caçadores and two batteries, one of mountain artillery and the other of howitzers. At 14:30 colonel Nepomuceno received the order to attack. The bulk of the 3rd Infantry Battalion would advance to Cantagalo hill and block the enemy, while the other forces would attack the defenders in
Ipanema and
Copacabana, trying to isolate them from the fort. The order was to attack as soon as possible, without fail before nightfall, but the detachment could only concentrate at 19:00. At the end of the morning, the commander of the fort used the 190mm Krupp cannons to fire at the left wing of the Ministry of War, in order to reach the table where the arrest order for Hermes da Fonseca had been signed. The first shot landed in front of
República square, raising dust and shrapnel and causing workers and residents to flee. The second fell into the back of Light & Power company, hitting a townhouse and killing a man, a woman and two children. Minister Calógeras himself telephoned to protest the damage. Colonel Nepomuceno had orders to cut off telephone connections and the water and electricity supply, but he did not permanently cut off communications so that the rebels would know of their defeat in the rest of the city. Without realizing it, Calógeras had indicated the target that had been hit. The gunners realized that they had forgotten to brake the gun during firing. Correcting their mistake, they fired again and hit the Ministry of War. The cannon fired twice more, hitting the courtyard and the opposite end. Two soldiers died and one was injured. Panic gripped the building. The headquarters was transferred to the Fire Department, in the same square, and then to another headquarters in Largo do Humaitá. Shortly before 15:00, colonel Nepomuceno, a personal friend of commander Euclides, summoned the fort to surrender, warning of the failure of the revolt. The fort's envoy said that they would only obey marshal Hermes da Fonseca and asked for an armistice. Colonel Nepomuceno granted it, under the reasoning of gaining time for the arrival of reinforcements, but president Epitácio Pessoa, sure of his position, did not want to negotiate. While the ceasefire was in effect, at 16:00, under his orders, the Fortress of Santa Cruz opened fire. There was a "duel of the fortresses". The rebels retaliated against government troops in Copacabana; one of the three shots hit the Guinle family mansion. At 18:30, Fort Imbuí joined the fire against Copacabana. Through the intervention of general Bonifácio, whose wife was in Imbuí, captain Euclides Hermes spared the target, choosing the Naval Battalion. Fort Vigia also participated. Loyalists were slow; Imbuí fired late, as the boiler needed three to four hours to provide sufficient pressure.
Fort São Luís was supposed to participate, but it didn't even get to fire. At 19:00, a new emissary from the Attack Forces Detachment warned that there would be no armistice and called for the surrender of the fort. It was a formality, as the arrival of night imposed the ceasefire. According to Siqueira Campos, a poorly communicated withdrawal order, during the bombardment of Santa Cruz, resulted in the destruction of a French 75mm cannon used in the external defense; it was thrown into the water. For Eduardo Gomes, it was a way to prevent the cannon from falling into enemy hands. Another possible motive was to express opposition to the French Military Mission. The cannon was new and was there for testing. Among the loyalists, the mountain artillery arrived at 20:00, and the other battery, at 21:30, positioning themselves respectively in Vila Rica and in the Leme gorge. The siege was only tightened at 23:00, with the troops reaching Serzedelo Correia square, with a patrol on the beach. In an elevated position on Toneleros street, captain
Eurico Gaspar Dutra served as an observer for the artillery. A company of the 3rd Infantry Division remained at Fort Vigia, and the cavalry remained near Cantagalo Hill, guarding
Leblon beach. The troops did not come closer as support from the Navy's cannons was expected.
Naval bombardment Inside the fort, with the supply of electricity and water being cut out, the defenders relied on candles and brackish water distilled from the sea. On 6 July, the lieutenants wanted to spare captain Euclides Hermes, the only officer with a wife and children, sending him to negotiate his surrender, but he did not want to leave. At 04:00 at night, minister Calógeras telephoned to warn the rebels of the total isolation of the fort, but gave them a guarantee of their lives. The commander gathered his officers and explained the situation. The rebels inside the fort knew of the imminent bombardment by the Navy and the other fortifications. A faction led by Siqueira Campos and Eduardo Gomes wanted to resist, but another considered the revolt over. The commander gave each the option of leaving or staying in the fort. Of the more than three hundred men in the garrison, only 29 remained — five officers (Euclides, Siqueira, Eduardo Gomes, Mário Carpenter and Newton Prado), two sergeants, a corporal, sixteen privates and five civilians. The prisoners were released. At 07:35, the battleship
São Paulo crossed the mouth of Guanabara Bay. Behind it, slightly displaced to port, came the
Minas Geraes. The destroyer
Paraná, with an admiral's pennant, accompanied the duo. Each battleship had a main battery of twelve 305mm guns (of which a maximum of ten could be used at the same time, due to the position of the turrets), against two cannons of the same caliber at the fort. But several factors favored the revolutionaries. The fort's shells had 1,500 meters more range than the battleships, and its concrete armor, up to 12 meters thick, was much stronger than the ships' steel armor. The geography of Guanabara Bay nullified the battleships' mobility advantage, forcing them to fight at close range (less than 7,250 meters), in which even their most protected parts could be pierced by the fort's shells. When Siqueira Campos saw the ships, the fort's 305mm guns were too high and aimed at Vila Militar. The revolutionaries were unable to maneuver the turret as the diesel engine failed—the result of sabotage in the confusion of the retreat. The Navy was probably aware of this, and therefore risked its ships at close range. The naval task force continued on a north-south axis, along the Ilha Rasa-Ilha da Laje line. At the signal from Fort Vigia,
São Paulo fired a first salvo at 08:00. Taking care not to hit Leblon, the bombardment continued for half an hour, firing 19 or 20 shells at the fort.
Minas Gerais did not fire, but the bombardment was supported on land by colonel Nepomuceno's batteries. The low fog did not allow the sailors to see the shells' impact zone. Only in the last salvo did they see smoke in the fort; according to captain Euclides, two shots finally hit. The shots did not pierce the protected area, but one of them opened a hole five feet deep. In the words of the fort's commander, "we received, inert, as simple spectators, the violent shells from the 305 pieces of
São Paulo". The ship was within range of the fort's 190mm guns, but sources differ as to whether or not the fort responded to the bombardment; Navy sources do not state that
São Paulo was a target. Shortly before sighting the battleship, the revolutionaries had fired the 190mm guns at targets on land. This bombardment continued even when the navy was close. The fort fired on
Ilha das Cobras, the army headquarters, Fort Vigia and the Catete Palace. On Ilha das Cobras, three marines died in the Naval Battalion barracks. As they did not find the tables with the calculations, the shot against Catete missed, destroying a nearby house. The Minister of War again telephoned the revolutionaries to ask for a ceasefire. The fort's commander agreed, warning, however, that he still had 72 tons of ammunition and would fight back any provocation. At 09:07 the fort raised the white flag. Around 10:00 two emissaries of the minister went to parliament with the rebels, but at the same time two
Breguet 14 planes from the navy, which was not informed of the agreement, bombed the fort, resulting in a fight with the emissaries. Calógeras proposed a personal conversation with Euclides Hermes, but this could be a trap. Siqueira Campos defined the conditions for the rebels, who wanted free passage to leave the country. The captain left the fort and was arrested at his home.
March on Atlântica Avenue Command of the fort was left to Siqueira Campos, and the plan was to bombard the city if the captain did not return within two hours. At 12:30, general , head of the
Casa Militar, telephoned to threaten the execution of Euclides Hermes if the fort fired again. Siqueira Campos managed to speak with Euclides by telephone, being informed that the Ministers of War and Navy guaranteed the life of the rebels if they left the fort and surrendered unconditionally. Siqueira put the handset on the hook and did not answer. The white flag remained flying over the fort. Siqueira Campos proposed bombing the city and then blowing up the fort in a collective suicide. Eduardo Gomes argued against that: the bombings would kill more civilians, and the fort belonged to Brazil. The soldiers agreed. It was then decided to abandon the fort. Their names were inscribed on the wall with nails. The flag of Brazil was cut into 28 or 29 pieces, one for each member. They distributed some brandy, filled their pockets with ammunition, and left, armed with
Mauser 1908 rifles and
Parabellum pistols. There would be no surrender: the way out was to fight the government supporters. They were "volunteers of death". They left the fort in the early afternoon. By then, surrender was expected in Catete. Upon being informed by the ministers, Epitácio Pessoa ordered an attack by the Navy and the land forces and dispatched Catete's own police guard to reinforce Copacabana. Not all the 28 men left the fort, and others scattered along the way. Passersby followed as spectators. They went along Atlântica Avenue towards Túnel Novo and from there to the presidential palace. Octavio Correia, a civilian and engineer from Rio Grande do Sul, joined the rebels, receiving Newton Prado's carbine. Meanwhile, four soldiers fled. Correia already knew the commander of the fort and the lieutenants before the revolt. At the time, Atlântica Avenue was already a
dual carriageway and several buildings were under construction. The gentrification of the shore was beginning, and the beach was frequented by various social classes. The revolutionaries stopped at Hotel Londres to drink water, where photographer Zenóbio Couto took the famous photographs. Siqueira Campos was left out. Two more defections followed. From afar, members of the 3rd Infantry Regiment shouted for them to surrender. The nearby loyalist commander, captain Pedro Chrysol Fernandes Brasil, commanded the 6th Company of the 3rd Infantry Regiment and had three platoons in Serzedelo Correia Square under lieutenants João Francisco Sauwen, and Pedro Miquelena. Upon learning of the rebels' departure, he left lieutenant Segadas Viana at Barroso Street (now Siqueira Campos Street), Miquelena at Hilário de Gouveia Street and Sauwen at the square. He acted under the orders of colonel Nepomuceno, but he lived a drama, as his son was among the rebels arrested at the Military School.
Final battle When lieutenant Segadas Viana approached the beach with his platoon to spot the rebels, he found them on the corner of Atlântica Avenue. A tense conversation ensued, pistols in hand, between him, Mário Carpenter (his colleague in the 3rd Infantry Regiment) and Siqueira Campos. Viana wanted them to surrender, and they wanted him to join them. Captain Brasil also approached. Carpenter, his subordinate, declared: "captain, we didn't come to surrender, we want to die fighting, against you. It is useless, therefore, to advise us". One of the rebels shouted: "We are going to Catete, captain". He insisted that it was madness, as they would have to face the entire regiment, and asked them to surrender, guaranteeing their life, but they threatened him personally. So he gave the order to fire and the fighting began. The first to die was a rebel soldier shot between Barroso Street and Hilário de Gouveia Street. The rebels divided into two groups and fired at the platoons of lieutenants Viana and Miquelena; Miquelena's platoon, suffering casualties, retreated to Serzedelo Correia square, linking up with Sauwen's. The platoon at the rear moved ahead in reinforcement. The avenue was under construction, and the rebels found shelter in the gap between the sand and the sidewalk. The government supporters, in turn, also climbed trees and roofs to shoot. With their rifles and machine guns, "it seemed to rain in the sea given the constant spray". The rebels, on the other hand, saved ammunition. The 9th Company of the 3rd Infantry Regiment, led by captain Floriano Gomes da Cruz, went to the rear of the rebels. Captain Brasil called for reinforcements and ammunition. One by one the rebels were shot. Captain Brasil had orders to finish them off with a bayonet charge, but he ignored it, hoping his enemies would cease fire and survive. The job fell to colonel
Tertuliano Potiguara, with about 100 men from the Military Police and the 3rd Infantry Regiment, coming from the presidential guard. "The charge order was given, and the last elements of the Copacabana garrison were broken". In the end, Potiguara's men cried out: "Lift up the living! Let the living rise!" The dead and wounded were collected on the beach. The 3rd Infantry Regiment company proceeded to Fort Copacabana, where they arrested, without resistance, eight soldiers and about 15 civilians.
Casualties in Copacabana The number of those rescued may have exceeded 80, including a team from Brasília Filmes that tried to film the revolt; the driver was killed in the shootout and the operator and bookkeeper were wounded. Epitácio Pessoa visited the revolutionaries in the hospital. Among the government supporters, colonel Potiguara reported six deaths, with several more injured, before the bayonet charge. In this charge, a sergeant was killed by Siqueira Campos, who was shot while stabbing his liver with his bayonet. Historian Glauco Carneiro counted 33 government supporters dead or wounded.
Gazeta de Notícias reported 14 rebels dead, in addition to 5 wounded. Among the loyalists, still with uncertainty, there might have been 10 dead and 4 wounded.
Correio da Manhã reported 30 wounded, between both forces, 13 privates, an "inferior" (probably a sergeant) and Mário Carpenter; at this point Newton Prado had not yet died. Another source gives 6 dead and 20 wounded among government forces in Copacabana. The number of rebels in combat was given as 18 (3 officers and 15 soldiers) the following morning by
Gazeta de Notícias. The newspaper was the first to use this number, which became mythical, being soon exalted in verse and prose. In words, "in a cold and rigorous calculation, that number that history has kept as a symbol, is not reached". There were several desertions along the way, and not all of them were recorded. The testimonies contradict each other. Eduardo Gomes remembered that Siqueira Campos identified 10 fighters, and personally mentioned four officers and about 20 enlisted men. Newton Prado reported two officers and 14 soldiers, omitting Carpenter and Eduardo Gomes, which would add up to 18. Captain Pedro Brasil gave a much higher estimate of approximately 60 rebels. The photograph, which excludes Siqueira Campos, depicts the other three officers, Otávio Correia and two soldiers in the foreground, with five or six indistinct figures behind. From the 28 men who remained in the fort, plus Octavio Correia, Hélio Silva listed ten, nine military and one civilian, in the shooting, including two unknown soldiers, a black and a white one. A soldier and a civilian accompanied the march but disbanded, being arrested far from the combat site. The two strangers died. Siqueira Campos, Eduardo Gomes, Otávio Correia, Mário Carpenter, Newton Prado and José Pinto de Oliveira were taken to the hospital wounded, where only the first two survived. Two soldiers (Hildebrando da Silva Nunes and Manoel Antônio dos Reis) "were discharged from the hospital, sued and arrested, but they did not last long". This enumeration includes the black soldier Pedro Ferreira de Melo, present in the photograph, as absent from the lists of dead, wounded and arrested, but he was the first of those killed. Another soldier included in this category by Hélio Silva, Manoel Antonio dos Santos, testified to
O Cruzeiro magazine 42 years later, declaring that he had fought on the beach alongside ten other men. He allegedly escaped from the beach and was arrested the next day.
Niterói On the other side of Guanabara Bay, on the night of 4 to 5 July, the rebellion was led by the commander of the Navy, Álvaro de Vasconcelos. With the support of state police chief César Sampaio Leite and a group of revolutionary civilians, including deputy , they occupied federal and state offices including the Telephone Company, preventing communication with Rio de Janeiro. The rebellion was quelled after the Rio de Janeiro police chief imposed his authority on the local police chief.
Mato Grosso Uprising in the south In Mato Grosso, general Joaquim Ignacio, commander of the 1st Military Circumscription, took part in the conspiracies against the government in
Campo Grande, for which reason he was dismissed on 30 March. The military in that state participated in several other revolts and
coronelist conflicts in the first decades of the Brazilian Republic. The new commander, Clodoaldo da Fonseca, was a relative of Hermes da Fonseca. When he took office, on 5 July, he found an already revolutionary environment. At night, meeting with his officers, he reported the revolution and claimed that it had the support of the majority of the army. They decided to rise up and issue a proclamation. Clodoaldo's leadership was symbolic, as the initiative actually rested with the lieutenants. Mato Grosso officers were unaware of the revolt's failure in Rio de Janeiro, as the telegraph and railway lines were interrupted. Clodoaldo was already aware of this, but he went ahead with the revolt for fear of a rebellion by his commanders or because of the commitment he had made before his departure to Mato Grosso. The revolutionaries followed pre-planning, occupying public buildings and calling up reservists. In
Corumbá, the military quartermaster's office was broken into to provide weapons and uniforms for the conscripts, but the effort to form another battalion of
Caçadores was unsuccessful. Revolutionary authorities promised peace and maintenance of state civil servants, but in several places they overthrew civilian authorities and looted tax collection and money-issuing bodies. Civilian support was limited, existing among supporters of the Republican Reaction. In
Porto Murtinho it was stronger, but martial law was applied. The rebellion had the aspect of a barracks revolt, without popular enthusiasm. To the north, in
Cuiabá, the state government of remained loyal to Epitácio Pessoa. In the 16th Battalion of
Caçadores, headquartered in the city, the commander delayed the orders of the Minister of War to hand over his battalion to the state command, but he was replaced and the battalion was outside the authority of Clodoaldo da Fonseca. The 10th Independent Cavalry Regiment (RCI), from
Bela Vista, also did not participate. It was divided and its commander was against the revolt. The monitor
Pernambuco, from the , went to
Ladário to help fight the revolt. The Minister of War praised the loyalty of the employees of the
Postal and Telegraph Company and of the Northwest Brazil Railroad. They emptied the railroad's water tanks to slow down the journey and passed on the telegraph communications to the loyalists, who were able to decipher the revolutionary plan.
Confrontation on the Paraná River The 1st Military Circumscription constituted the Provisional Liberating Division, organized into two brigades, receiving units from Campo Grande, Porto Murtinho and Ponta Porã. The main one was the 17th Battalion of
Caçadores, under the interim command of lieutenant Joaquim Távora. It is difficult to quantify the number of troops, but it was probably between 800 and 1,000 men. The plan was to concentrate forces in
Três Lagoas, cross the
Paraná River, enter São Paulo through
Araçatuba and face the forces from São Paulo and allies in support of the lieutenants in Rio de Janeiro. The first train only left Campo Grande on 8 July. Upon arriving at Três Lagoas, they discovered that railway officials had removed the ferry from trains and other ships, leaving them on the other side and without essential parts. Even so, the revolutionaries seized a barge for 25 to 30 men, built another and captured a boat. They positioned four Krupp caliber 8 cannons, taken from
Fort Coimbra, at the mouth of the
Sucuriú River, pointing to the São Paulo side. On 10 July, colonel Tertuliano Potiguara was tasked with crushing the uprising. President Epitácio Pessoa dismissed Clodoaldo da Fonseca on 12 July. Forces from the (including the 4th Battalion of
Caçadores) and the
Public Force of São Paulo moved to the Paraná River, on the border of Mato Grosso. A squadron of three planes did the reconnaissance. The Public Force contingent included 255 soldiers and 21 officers from its 2nd Infantry Battalion reinforcing colonel Potiguara, while the 4th Battalion, with 617 men, remained in reserve in
Bauru. The loyalist forces concentrated near Três Lagoas, on the São Paulo side. A veteran of World War I, colonel Potiguara prepared to cross the Paraná River under the cover of his artillery and machine guns. The fight never took place. On 13 July, general Alberto Cardoso de Aguiar conferred with Clodoaldo da Fonseca at the Três Lagoas railway station, convincing him to surrender unconditionally to avoid bloodshed. Some of the most extreme revolutionaries still wanted to fight, but Clodoaldo gave up command and was arrested. The new commander, general Cardoso de Aguiar, returned the units to their headquarters. Mato Grosso reservists, with the exception of those in the 16th Battalion of
Caçadores, were disbanded. ==Political consequences==
