Ubaldo Díaz Fuentes was born on August 2, 1929, in Güira de Melena. His childhood was very similar to that of most children of that time; an unflattering future. From a very young age, he began to combine baseball and fishing practices with his work in his uncle's coal mine. In 1947 he moved to Havana and began working in the Mercado Único.
The coup d'état of March 10, 1952 changed the life of Ubaldo Díaz Fuentes. He began his fight in Triple A, an authentic organization directed by Aureliano Sánchez Arango. He actively participated in the movement created by the Moncadistas amnesty. His first major action occurred on August 4, 1955, in Santa Marta and Lindero, in Havana. The action consisted of Ubaldo had to transfer some weapons in his truck to be distributed later. The weapons would be useful for the youth of the Revolutionary Directorate to carry out an attack against Fulgencio Batista. The plan was fulfilled, but Ubaldo was already in the area, when he realized that he was surrounded by the police. He managed to escape and for three months had to be hidden in the farm of some friends who protected him.
At the beginning of 1956 some of Ubaldo Díaz Fuentes' comrades in Havana were arrested. Eduardo Cartaya, who was the head of the organization, reported the location of the weapons. Cartaya went to the Mercado Unico and told Ubaldo that another comrade of the movement wanted to see the weapons. Ubaldo took them to the Tumbadero and when showing the weapons, Lieutenant Esteban Ventura Novo identified himself and told him he was arrested.
That was the first and last time Ubaldo was arrested. The trial was suspended several times. Ubaldo was sentenced to serve three years in prison for alleged attack against the President of the Republic. In the Castillo del Príncipe, he continued his revolutionary activity. On December 30, 1956, he managed to escape with two comrades of the Revolutionary Directorate, making the tyranny forces look ridiculous.
At the beginning of 1957, being a fugitive, Ubaldo Díaz Fuentes participated in the attack on the motorized police, on 25th Street and Malecón, mocking the forces of the regime dressed as a medical student, in a white coat. On March 13, 1957, he was part of the command that assaulted the Presidential Palace and died in action. His wake and burial were true manifestations of mourning throughout the town of Güira de Melena. In each dismayed face, the firmness of the fight could be guessed. A sample of it was that, even with the extreme security measures that existed, voices of Viva Cuba Libre were heard!
