On This Day - What happened 20 April 1961 AD

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.
