June 20, 1959: Following the failure of the initial two invasion forces on June 14th, Havana landed a third group near Estero Hondo. Led by Antonio Campos, exiles forces claimed the column established operations in the mountainous areas of central and northern parts of the Dominican Republic. However, the failure of the mission’s major components led Havana to cease direct efforts to overthrow the government. In response to Castro’s aggression, the Dominica Republic severed diplomatic ties. The following month, Fidel Castro told American journalists that Cuba had provided “the best men available” for this carefully planned and well-armed mission. In tribute to the failed mission, Dominican leftists created a Castroite political effort known as the 14th of June Movement.
