Dominican Republic strongman Rafael Trujillo and Castro both supported attempts to overthrow each other. On 14 June 1959, a Cuban-supported invasion force landed from an airplane at Constanza, Dominican Republic, only to be immediately massacred. A week later, two yachts offloaded 186 invaders onto Chris-Craft launches for a landing on the North coast. Dominican Air Force pilots fired rockets from their Vampire Jets into the approaching launches, killing all but 30 men, who managed to make it to the beaches at Maimon and Estero Hondo. Trujillo ordered his son, Ramfis, to lead the hunt for the survivors, and soon they were captured. The leaders of the invasion were taken aboard a Dominican Air Force plane and then pushed out in mid-air, falling to their deaths. Militant anti-Castro groups, funded by exiles, by the Central Intelligence Agency (CIA) and by Trujillo's Dominican government, carried out armed attacks and set up guerrilla bases in Cuba's mountainous regions. This led to the six-year Escambray rebellion (1959–65), which lasted longer and involved more soldiers than the Cuban Revolution.
