After Dominican dictator Rafael Trujillo formed an anti-Castro foreign legion of 3,000 soldiers-of-fortune, including 200 Cuban exiles and 400 Spanish volunteers from the Blue Division (which had fought for Germany on the Eastern Front during WWII), Castro sponsored or organized several attempts to unseat him. On 14 June 1959, approximately 200 Dominican exiles and Cuban revolutionaries launched an invasion of the Dominican Republic from Cuba with the hope of overthrowing the Trujillo regime. Trujillo's forces quickly routed the invaders. A week later, another group of invaders in 2 yachts were intercepted and blasted by mortar fire and bazookas from the shore. Trujillo's planes, directed by his son Ramfis, commander of the air force, zoomed low over the yachts and shot rockets, killing most of the invaders. A few survivors managed to swim to the shore and escape into the forest; the military used napalm to get them out. The leaders of the invasion were taken aboard a Dominican Air Force plane and then pushed out in mid-air, falling to their deaths. Trujillo responded by supporting an October 1960 uprising in the Escambray Mountains by 1,000 Cuban counter-revolutionaries. The rebels were defeated and their leader, William Morgan, was captured and executed.
