Almost all of Fidel Castro's followers were
Partido Ortodoxo Youth rank and file of the lower middle class and working class. Of the 136 insurgents whose ages are known, the average age was 26, the same as that of Castro. Nine rebels were in their teens, 96 were in their twenties, 27 in their thirties, and five over 40. The
Afro-Cuban composition of the group was limited to two Africans and 12 Cubans of partial African ancestry, partly because most biracial Cubans identified with Batista, who was of mixed blood. Only two of the group were women,
Haydée Santamaría and
Melba Hernández, both of whom went on to become politicians. After
Batista's military coup on 10 March 1952, Fidel Castro and his group began to train young men to engage in the struggle, along with other anti-Batista groups, against an illegitimate government. Castro claimed that they trained 1,200 men within a few months, training at the
University of Havana and at firing ranges in
Havana, disguising themselves as businessmen interested in hunting and clay pigeon shooting. The weapons included 40 12- and 16-gauge shotguns, 35
Mosberg and Remington .22 rifles, 60 handguns of various models, a malfunctioning .45 caliber submachine gun, 24 rifles of different caliber, including eight Model 1898
Krag–Jørgensen rifles, a
.30-06 Model 1903 Springfield rifle, three
sawed-off 1892 .44-caliber Winchester rifles, and a
.30 caliber M1 Garand rifle with a folding metal stock. Fidel Castro decided that army uniforms were needed for the Moncada attack. He discussed this with Calabazar cell leader Pedro Trigo Lopez (
es), who suggested approaching his relative Florentino Fernandez Leon, a 26-year-old military hospital orderly in Jaimanitas. Fernandez agreed and received $200 to purchase surplus uniforms, weapons, and ammunition. He then pilfered from the military hospital laundry most of the blue uniforms needed to attire the rebels. The night before the attack, the men gathered at a farm in
Siboney, where they learned what the objective was. The plan was to secure the barracks and gain possession of the weapons stored within, and to use the building's army communications equipment to spread false messages for several hours to confuse the military. In the meantime, the weapons would be removed and hidden throughout the city to use in the continuing struggle, and
Santiago's radio station would be taken to broadcast the speeches of
Eduardo Chibás, in order to mobilize the public with the ultimate aim of bringing down the
Batista government. The men left the farm at 4:45 am on 26 July 1953, planning to attack at dawn. The date of the attack was specifically chosen because the
fiestas in
Santiago are held on 25 July. ==The attack==
