Fidel Castro

His Early Years
Fidel Castro had learned of a plannedd expedition to overthrow the right-wing government of Rafael Trujillo, a U.S. ally, in the Dominican Republic. He joined the expedition because he was President of the University Committee for Democracy in the Dominican republic, thus cementing his place in political confrontations.
The Movement and the Moncada Barracks attack
Castro fomred a group called "The Movement" which operated along a clandestine cell system, publishing underground newspaper El Acusador (the Accuser), and at the same time he was arming and training anti-Batista recruits. In July of 1952 The Movement went on a recruitment drive, gaining them around 1,200 memebers in a year! Although Fidel Castro was a revolutionary socialist, he avoided an alliance with the communist Popular Socalist Party (PSP), fearing it would frighten away political moderates, but kept in contact with the PSP members.
The Raiding of the Spanish barracks
Castro gathered 165 revolutionaries for the mission, ordeering his troops not to cause bloodshed unless they met armed resistance. The attack took place on July 26, 1953, and faced trouble from the start; 3 of the 16 cars tat set out from Santiago failed to get there. When The Movement was reaching the barracks the larm was raised and most of the rebels were pinned down by machine gun fire, four being killed before a retreat was ordered from Castro. The final death toll was 6 fatalities and 15 other casualties for the rebels and 19 dead and 27 wounded from the Spanish guards. The Movement were gathered up, some exicuted and others, including Castro, were transported to a prison north of Santiago.
