What happened April 1961 AD

Soon after the success of the Cuban Revolution, militant counter-revolutionary groups developed in an attempt to overthrow the new regime. Undertaking armed attacks against government forces. On 3 April 1961, a bomb attack on militia barracks in Bayamo killed four militia, and wounded eight more.

On 4 April 1961, President Kennedy then approved the Bay of Pigs plan (also known as Operation Zapata), because it had a sufficiently long airfield, it was farther away from large groups of civilians than the Trinidad plan, and it was less "noisy" militarily, which would make denial of direct US involvement more plausible. The invasion landing area was changed to beaches bordering the Bahía de Cochinos (Bay of Pigs) in Las Villas Province.

The Eisenhower administration had created a plan to overthrow Fidel Castro's regime in Cuba. Led by the Central Intelligence Agency (CIA), with help from the U.S. military, the plan was for an invasion of Cuba by a counter-revolutionary insurgency composed of U.S.-trained, anti-Castro Cuban exiles led by CIA paramilitary officers. The intention was to invade Cuba and instigate an uprising among the Cuban people, hoping to remove Castro from power. Kennedy approved the final invasion plan on April 4, 1961.

On 9 April 1961, Brigade 2506 personnel, ships, and aircraft started transferring from Guatemala to Puerto Cabezas. Curtiss C-46s were also used for transport between Retalhuleu and a CIA base (code-named JMTide, aka Happy Valley) at Puerto Cabezas.

The Cuban security apparatus knew the invasion was coming, via their extensive secret intelligence network. Nevertheless, days before the invasion, multiple acts of sabotage were carried out, such as the El Encanto fire, an arson attack in a department store in Havana on 13 April that killed one shop worker.

Under cover of darkness, the invasion fleet set sail from Puerto Cabezas, Nicaragua and headed towards the Bay of Pigs on the night of 14 April.

About 90 minutes after the eight B-26s had taken off from Puerto Cabezas to attack Cuban airfields, another B-26 departed on a deception flight that took it close to Cuba but headed north towards Florida. Like the bomber groups, it carried false FAR markings and the same number 933 as painted on at least two of the others. Before departure, the cowling from one of the aircraft's two engines was removed by CIA personnel, fired upon, then re-installed to give the false appearance that the aircraft had taken ground fire at some point during its flight. At a safe distance north of Cuba, the pilot feathered the engine with the pre-installed bullet holes in the cowling, radioed a mayday call, and requested immediate permission to land at Miami International airport. He landed and taxied to the military area of the airport near an Air Force C-47 and was met by several government cars. The pilot was Mario Zúñiga, formerly of the FAEC (Cuban Air Force under Batista), and after landing, he masqueraded as 'Juan Garcia' and publicly claimed that three colleagues had also defected from the FAR.

On 15 April, CIA-supplied B-26s bombed three Cuban military airfields; the U.S. announced that the perpetrators were defecting Cuban air force pilots, but Castro exposed these claims as false flag misinformation.

On April 15,The Cuban national police, led by Efigenio Ameijeiras, started the process of arresting thousands of suspected anti-revolutionary individuals, and detaining them in provisional locations such as the Karl Marx Theatre, the moat of Fortaleza de la Cabana and the Principe Castle all in Havana, and the baseball park in Matanzas.

During the night of 14/15 April, a diversionary landing was planned near Baracoa, Oriente Province, by about 164 Cuban exiles commanded by Higinio 'Nino' Diaz.The reconnaissance boats turned back to the ship after their crews detected activities by Cuban militia forces along the coastline. As a result of those activities, at daybreak, a reconnaissance sortie over the Baracoa area was launched from Santiago de Cuba. That was a FAR (Fuerza Aérea Revolucionaria) (Cuban Air Force) T-33, piloted by Lt Orestes Acosta, and it crashed fatally into the sea.

On 15 April 1961, at about 06:00 am Cuban local time, eight Douglas B-26B Invader bombers in three groups simultaneously attacked three Cuban airfields at San Antonio de los Baños and at Ciudad Libertad (formerly named Campo Columbia), both near Havana, plus the Antonio Maceo International Airport at Santiago de Cuba.

At 10:30 am on 15 April at the United Nations, the Cuban Foreign Minister Raúl Roa accused the US of aggressive air attacks against Cuba, and that afternoon formally tabled a motion to the Political (First) Committee of the UN General Assembly. Only days earlier, the CIA had unsuccessfully attempted to entice Raúl Roa into defecting.

On 16 April, Merardo Leon, Jose Leon, and 14 others staged an armed uprising at Las Delicias Estate in Las Villas, with only four surviving. Leonel Martinez and three others took to the countryside.

Late on 16 April, the CIA/Brigade 2506 invasion fleet converged on 'Rendezvous Point Zulu', about 65 kilometres (40 mi) south of Cuba, having sailed from Puerto Cabezas in Nicaragua where they had been loaded with troops and other materiel, after loading arms and supplies at New Orleans.

On the night of 15/16 April, the Nino Diaz group failed in a second attempted diversionary landing at a different location near Baracoa.

At about 06:50, south of Playa Larga, Houston was damaged by several bombs and rockets from a Sea Fury and a T-33, and about two hours later captain Luis Morse intentionally beached it on the western side of the bay. About 270 troops had been unloaded, but about 180 survivors who struggled ashore were incapable of taking part in further action because of the loss of most of their weapons and equipment. The loss of Houston was a great blow to the brigadistas as that ship was carrying much of the Brigade 2506's medical supplies, which meant that wounded brigadistas had to make do with inadequate medical care.

At about 07:00, two invading FAL B-26s attacked and sank the Cuban Navy Patrol Escort ship El Baire at Nueva Gerona on the Isle of Pines. They then proceeded to Girón to join two other B-26s to attack Cuban ground troops and provide distraction air cover for the paratroop C-46s and the CEF ships under air attack.

At about 07:30, five C-46 and one C-54 transport aircraft dropped 177 paratroops from the parachute battalion of Brigade 2506 in an action code-named Operation Falcon. About 30 men, plus heavy equipment, were dropped south of the Central Australia sugar mill on the road to Palpite and Playa Larga, but the equipment was lost in the swamps, and the troops failed to block the road. Other troops were dropped at San Blas, at Jocuma between Covadonga and San Blas, and at Horquitas between Yaguaramas and San Blas. Those positions to block the roads were maintained for two days, reinforced by ground troops from Playa Girón and tanks.

At about 08:30, a FAR Sea Fury piloted by Carlos Ulloa Arauz crashed in the bay, due to stalling or anti-aircraft fire, after encountering a FAL C-46 returning south after dropping paratroops.

By 09:00, Cuban troops and militia from outside the area had started arriving at the Central Australia sugar mill, Covadonga and Yaguaramas. Throughout the day they were reinforced by more troops, heavy armour and T-34 tanks typically carried on flat-bed trucks.

At about 09:30, FAR Sea Furies and T-33s fired rockets at Rio Escondido, which then 'blew up' and sank about 3 kilometres (1.9 mi) south of Girón. Rio Escondido was loaded with aviation fuel and as the ship started to burn, the captain gave the order to abandon ship with the ship being destroyed in three explosions shortly afterwards. Rio Escondido carried not only fuel, but also enough ammunition, food and medical supplies to last ten days and the radio that allowed the Brigade to communicate with the Liberation Air Force. The loss of the communications ship Rio Escondido meant that San Román was only able to issue orders to the forces at Blue Beach, and he had no idea of what was happening at Red Beach or with the paratroopers.

A messenger from Red Beach arrived at about 10:00 am asking San Román to send tank and infantry to block the road from the Central Australia sugar mill, a request that he agreed to. It was not expected that government forces would be counter-attacking from this direction.

By about 11:00, the two remaining freighters Caribe and Atlántico, and the CIA LCIs and LCUs, started retreating south to international waters, but still pursued by FAR aircraft. At about noon, a FAR B-26 exploded due to heavy anti-aircraft fire from Blagar, and pilot Luis Silva Tablada (on his second sortie) and his crew of three were lost.

At 2:30 pm a group of militiamen from the 339th Battalion set up a position, which came under attack from the brigadista M41 Walker Bulldog tanks, who inflicted heavy losses on the defenders. This action is remembered in Cuba as the "Slaughter of the Lost Battalion" as most of the militiamen perished.

By 16:00, Fidel Castro had arrived at the Central Australia sugar mill, joining José Ramón Fernández whom he had appointed as battlefield commander before dawn that day.

At 8:00 pm, the Cuban Army opened fire with its 76.2mm and 122mm artillery guns on the brigadista forces at Playa Larga, which was followed by an attack by T-34 tanks at about midnight.

At about 21:00 on 17 April 1961, a night air strike by three FAL B-26s on San Antonio de Los Baños airfield failed, reportedly due to incompetence and bad weather. Two other B-26s had aborted the mission after take-off. Other sources allege that heavy anti-aircraft fire scared the aircrews As night fell, Atlantico and Caribe pulled away from Cuba to be followed by Blagar and Barbara J.

The CIA and the Democratic Revolutionary Front had based a 1,400-strong army, Brigade 2506, in Nicaragua. On the night of 16 to 17 April, Brigade 2506 landed along Cuba's Bay of Pigs and engaged in a firefight with a local revolutionary militia .

On April 17, 1961, 1,400 U.S.-trained Cuban exiles invaded Cuba during the Bay of Pigs Invasion. Guevara did not play a key role in the fighting, as one day before the invasion a warship carrying Marines faked an invasion off the West Coast of Pinar del Río and drew forces commanded by Guevara to that region.

At about 00:00 on 17 April 1961, the two CIA LCIs Blagar and Barbara J, each with a CIA 'operations officer' and an Underwater Demolition Team (UDT) of five frogmen, entered the Bay of Pigs (Bahía de Cochinos) on the southern coast of Cuba. They headed a force of four transport ships (Houston, Río Escondido, Caribe and Atlántico) carrying about 1,400 Cuban exile ground troops of Brigade 2506, plus the Brigade's M41 Walker Bulldog tanks, and other vehicles in the landing craft.

During the night of 16/17 April, a mock diversionary landing was organized by CIA operatives near Bahía Honda, Pinar del Río Province. A flotilla containing equipment that broadcast sounds and other effects of a shipborne invasion landing provided the source of Cuban reports that briefly lured Fidel Castro away from the Bay of Pigs battlefront area.

The Bay of Pigs Invasion began on April 17, 1961.

On 17 April 1961, Osvaldo Ramírez (leader of the rural resistance to Castro) was captured by Castro's forces in Aromas de Velázquez, and immediately executed.

At about 01:00, Blagar, as the battlefield command ship, directed the principal landing at Playa Girón (code-named Blue Beach), led by the frogmen in rubber boats followed by troops from Caribe in small aluminium boats, then LCVPs and LCUs with the M41 Walker Bulldog tanks. Barbara J, leading Houston, similarly landed troops 35 km further northwest at Playa Larga (code-named Red Beach), using small fiberglass boats. The unloading of troops at night was delayed, due to engine failures and boats damaged by unforeseen coral reefs; the CIA had originally believed that the coral reef was seaweed. As the frogmen came in, they were shocked to discover that the Red Beach was lit with floodlights, which led to the location of the landing being hastily changed. As the frogmen landed, a firefight broke out when a jeep carrying Cuban militia happened by. The few militias in the area succeeded in warning Cuban armed forces via radio soon after the first landing, before the invaders overcame their token resistance.

By 5:00 am, Oliva started to order his men to retreat as he had almost no ammunition or mortar rounds left.

At daybreak around 06:30 am, three FAR Sea Furies, one B-26 bomber and two Lockheed T-33 fighter jets started attacking those CEF ships still unloading troops.

Brigade 2506's M41 Walker Bulldog tanks had all landed by 7:30 am at Blue Beach and all of the troops by 8:30 am. Neither San Román at Blue Beach nor Erneido Oliva at Red Beach could communicate as all of the radios had been soaked in the water during the landings.

At about 11:00 am, the Cuban government began an offensive to take San Blas. San Román ordered all of the paratroopers back in order to hold San Blas, and they halted the offensive. During the afternoon, Castro kept the brigadistas under steady air attack and artillery fire, but did not order any new major attacks.

At 14:00, President Kennedy received a telegram from Nikita Khrushchev in Moscow, stating the Russians would not allow the US to enter Cuba, and implied swift nuclear retribution to the United States heartland if their warnings were not heeded.

During the night of 17–18 April, the force at Red Beach came under repeated counter-attacks from the Cuban Army and militia. As casualties mounted and ammunition was used up, the brigadistas steadily gave way. Airdrops from four C-54s and 2 C-46s had only limited success in landing more ammunition.

As the men from Red Beach arrived at Girón, San Román and Oliva met to discuss the situation. With ammunition running low, Oliva suggested that the Brigade 2506 retreat into the Escambray mountains to wage guerilla warfare, but San Román decided to hold the beachhead.

At 1:00 am, Cuban Army infantrymen and militiamen started an offensive. Despite heavy losses on the part of the Communist forces, the shortage of ammunition forced the brigadistas back and the T-34 tanks continued to force their way past the wreckage of the battlefield to press on the assault.

At 10 am, a tank battle had broken out, with the brigadista holding their line until about 2:00 pm, which led Olvia to order a retreat into Girón.

At about 17:00 on 18 April, FAL B-26s attacked a Cuban column of 12 private buses leading trucks carrying tanks and other armor, moving southeast between Playa Larga and Punta Perdiz. The vehicles, loaded with civilians, militia, police, and soldiers, were attacked with bombs, napalm, and rockets, suffering heavy casualties.

During the night of 18 April, a FAL C-46 delivered arms and equipment to the Girón airstrip occupied by Brigade 2506 ground forces and took off before daybreak on 19 April.

By about 10:30 am on 18 April, Cuban troops and militia, supported by the T-34 tanks and 122mm artillery, took Playa Larga after Brigade forces had fled towards Girón in the early hours. During the day, Brigade forces retreated to San Blas along the two roads from Covadonga and Yaguaramas. By then, both Fidel Castro and José Ramón Fernández had re-located to that battlefront area.

Following the last air attacks, San Román ordered his paratroopers and the men of the 3rd Battalion to launch a surprise attack, which was initially successful, but soon failed. With the brigadistas in disorganized retreat, the Cuban Army and militiamen started to advance rapidly, taking San Blas only to be stopped outside of Girón at about 11 am.

The final air attack mission (code-named Mad Dog Flight) comprised five B-26s, four of which were manned by American CIA contract aircrews and volunteer pilots from the Alabama Air Guard. One FAR Sea Fury (piloted by Douglas Rudd) and two FAR T-33s (piloted by Rafael del Pino and Alvaro Prendes) shot down two of these B-26s, killing four American airmen. Combat air patrols were flown by Douglas A4D-2N Skyhawk jets of VA-34 squadron operating from USS Essex, with nationality and other markings removed. Sorties were flown to reassure Brigade soldiers and pilots, and to intimidate Cuban government forces without directly engaging in acts of war.

By April 19, 1961, the Cuban government had captured or killed the invading exiles, and Kennedy was forced to negotiate for the release of the 1,189 survivors. Twenty months later, Cuba released the captured exiles in exchange for $53 million worth of food and medicine.

Late on 19 April, destroyers USS Eaton (code-named Santiago) and USS Murray (code-named Tampico) moved into Cochinos Bay to evacuate retreating Brigade soldiers from beaches, before fire from Cuban army tanks caused Commodore Crutchfield to order a withdrawal.

On 19 April 1961, at least seven Cubans plus two CIA-hired US citizens (Angus K. McNair and Howard F. Anderson) were executed in Pinar del Rio province, after a two-day trial.

On 20 April, Humberto Sorí Marin was executed at Fortaleza de la Cabaña, having been arrested on 18 March following infiltration into Cuba with 14 tons of explosives. His fellow conspirators Rogelio González Corzo (alias "Francisco Gutierrez"), Rafael Diaz Hanscom, Eufemio Fernandez, Arturo Hernandez Tellaheche and Manuel Lorenzo Puig Miyar were also executed.

Castro ordered Captain José Ramón Fernández to launch the counter-offensive, before taking personal control of it. After bombing the invaders' ships and bringing in reinforcements, Castro forced the Brigade to surrender on 20 April.

On 21 April, Eaton and Murray, joined on 22 April by destroyers USS Conway and USS Cony, plus submarine USS Threadfin and a CIA PBY-5A Catalina flying boat, continued to search the coastline, reefs, and islands for scattered Brigade survivors, about 24–30 being rescued.

Yaeko Sakano, more often referred to as Yaeko Ueno, was an unmarried partner to Hidesaburō Ueno for about 10 years until his death in 1925. Hachikō was reported to have shown great happiness and affection towards her whenever she came to visit him. Yaeko died on 30 April 1961 at the age of 76 and was buried at a temple in Taitō, further away from Ueno's grave, despite her requests to her family members to be buried with her late partner.

On 9 April 1961, Brigade 2506 personnel, ships, and aircraft started transferring from Guatemala to Puerto Cabezas. Curtiss C-46s were also used for transport between Retalhuleu and a CIA base (code-named JMTide, aka Happy Valley) at Puerto Cabezas.

About 30 men, plus heavy equipment, were dropped south of the Central Australia sugar mill on the road to Palpite and Playa Larga, but the equipment was lost in the swamps, and the troops failed to block the road. Other troops were dropped at San Blas, at Jocuma between Covadonga and San Blas, and at Horquitas between Yaguaramas and San Blas. Those positions to block the roads were maintained for two days, reinforced by ground troops from Playa Girón and tanks.

At about 08:30, a FAR Sea Fury piloted by Carlos Ulloa Arauz crashed in the bay, due to stalling or anti-aircraft fire, after encountering a FAL C-46 returning south after dropping paratroops.

By 09:00, Cuban troops and militia from outside the area had started arriving at the Central Australia sugar mill, Covadonga and Yaguaramas. Throughout the day they were reinforced by more troops, heavy armour and T-34 tanks typically carried on flat-bed trucks.

At about 09:30, FAR Sea Furies and T-33s fired rockets at Rio Escondido, which then 'blew up' and sank about 3 kilometres (1.9 mi) south of Girón. Rio Escondido was loaded with aviation fuel and as the ship started to burn, the captain gave the order to abandon ship with the ship being destroyed in three explosions shortly afterwards. Rio Escondido carried not only fuel, but also enough ammunition, food and medical supplies to last ten days and the radio that allowed the Brigade to communicate with the Liberation Air Force.

This action is remembered in Cuba as the "Slaughter of the Lost Battalion" as most of the militiamen perished.

By 16:00, Fidel Castro had arrived at the Central Australia sugar mill, joining José Ramón Fernández whom he had appointed as battlefield commander before dawn that day.

At about 01:00, Blagar, as the battlefield command ship, directed the principal landing at Playa Girón (code-named Blue Beach), led by the frogmen in rubber boats followed by troops from Caribe in small aluminium boats, then LCVPs and LCUs with the M41 Walker Bulldog tanks. Barbara J, leading Houston, similarly landed troops 35 km further northwest at Playa Larga (code-named Red Beach), using small fiberglass boats. The unloading of troops at night was delayed, due to engine failures and boats damaged by unforeseen coral reefs; the CIA had originally believed that the coral reef was seaweed.

During the night of 18 April, a FAL C-46 delivered arms and equipment to the Girón airstrip occupied by Brigade 2506 ground forces and took off before daybreak on 19 April.

By about 10:30 am on 18 April, Cuban troops and militia, supported by the T-34 tanks and 122mm artillery, took Playa Larga after Brigade forces had fled towards Girón in the early hours. During the day, Brigade forces retreated to San Blas along the two roads from Covadonga and Yaguaramas. By then, both Fidel Castro and José Ramón Fernández had re-located to that battlefront area.

Following the last air attacks, San Román ordered his paratroopers and the men of the 3rd Battalion to launch a surprise attack, which was initially successful, but soon failed. With the brigadistas in disorganized retreat, the Cuban Army and militiamen started to advance rapidly, taking San Blas only to be stopped outside of Girón at about 11 am.

The final air attack mission (code-named Mad Dog Flight) comprised five B-26s, four of which were manned by American CIA contract aircrews and volunteer pilots from the Alabama Air Guard. One FAR Sea Fury (piloted by Douglas Rudd) and two FAR T-33s (piloted by Rafael del Pino and Alvaro Prendes) shot down two of these B-26s, killing four American airmen. Combat air patrols were flown by Douglas A4D-2N Skyhawk jets of VA-34 squadron operating from USS Essex, with nationality and other markings removed. Sorties were flown to reassure Brigade soldiers and pilots, and to intimidate Cuban government forces without directly engaging in acts of war.

By April 19, 1961, the Cuban government had captured or killed the invading exiles, and Kennedy was forced to negotiate for the release of the 1,189 survivors. Twenty months later, Cuba released the captured exiles in exchange for $53 million worth of food and medicine.

Late on 19 April, destroyers USS Eaton (code-named Santiago) and USS Murray (code-named Tampico) moved into Cochinos Bay to evacuate retreating Brigade soldiers from beaches, before fire from Cuban army tanks caused Commodore Crutchfield to order a withdrawal.

On 19 April 1961, at least seven Cubans plus two CIA-hired US citizens (Angus K. McNair and Howard F. Anderson) were executed in Pinar del Rio province, after a two-day trial.

On 20 April, Humberto Sorí Marin was executed at Fortaleza de la Cabaña, having been arrested on 18 March following infiltration into Cuba with 14 tons of explosives. His fellow conspirators Rogelio González Corzo (alias "Francisco Gutierrez"), Rafael Diaz Hanscom, Eufemio Fernandez, Arturo Hernandez Tellaheche and Manuel Lorenzo Puig Miyar were also executed.

Castro ordered Captain José Ramón Fernández to launch the counter-offensive, before taking personal control of it. After bombing the invaders' ships and bringing in reinforcements, Castro forced the Brigade to surrender on 20 April.

On 21 April, Eaton and Murray, joined on 22 April by destroyers USS Conway and USS Cony, plus submarine USS Threadfin and a CIA PBY-5A Catalina flying boat, continued to search the coastline, reefs, and islands for scattered Brigade survivors, about 24–30 being rescued.

Yaeko Sakano, more often referred to as Yaeko Ueno, was an unmarried partner to Hidesaburō Ueno for about 10 years until his death in 1925. Hachikō was reported to have shown great happiness and affection towards her whenever she came to visit him. Yaeko died on 30 April 1961 at the age of 76 and was buried at a temple in Taitō, further away from Ueno's grave, despite her requests to her family members to be buried with her late partner.
