Department of Manuscripts and Archives1959 OctoberengspaImages taken from the balcony of the Presidential Palace at a mass rally called by Fidel Castro on October 26, 1959, and organized by government-affiliated labor unions to express support for Fidel Castro's decision to arrest Commander Huber Matos for resigning his military post and to charge him with treason and attempting to conspire against the revolutionary government. Matos was later sentenced to twenty years in prison. The rally was also called in order to show popular support for the recommissioning of Revolutionary Tribunals to try internal enemies of Cuba for counterrevolution and to protest recent air raids by counterrevolutionary exile groups, largely comprised of batistianos, based in Florida.
