- He writes a new letter relating is activities during a day in prison. In one paragraph he writes: "It's eleven o'clock in the evening. Since six o'clock in the afternoon I've been reading a book by Lenin, ’The State and the Revolution”, after finishing The 18 of Brumaire by Luis Bonaparte and The Civil Wars in France, both by Marx, closely related and of immense value ... and:" He later says " My journeys through the fields of Philosophy have served me well After racking my brains for a long time with Kant, Marx himself seems easier than Our Heavenly Father. Both Marx and Lenin had a terrible spirit always seeking debate and I am here amused, I laugh and enjoy reading them, they were implacable and fearsome with the enemy. Two true prototypes of revolutionaries"
Chronology
- He writes a letter where he talks about solitude in prison. "You cannot imagine how much energy this solitude consumes. Sometimes I am exhausted. At those times is when one gets tired of everything, there is no refuge from tedium. Sensitivity becomes dull and the days pass in lethargy" . He also reflects his personality and sense of life in the letter: "... I have no personal ambitions; all my motives are moral, a sense of honor, a sense of dignity, a sense of duty."
- He writes a letter to Melba Hernández in which he instructs her about steps to be taken to fight against the Batista dictatorship: "We have to coordinate the work between our people both here and abroad (...) Any coordination effort coming from other factors must be considered with extreme care, just in case they are simply trying to use our name ... Under no circumstance shall we allow anyone to look down to us; we must never reach any agreement but on firm, clear grounds of probable and beneficial benefits for Cuba. Otherwise it is preferable to walk alone and keep the flag high until these formidable boys who are imprisoned are free ... "
He write a message for Melba Hernández warning her about the division seeking and opportunist actions of Carlos Prío Authentic Organization (OA) and the Aureliano Sánchez Arango’s Triple A, with millions in resources and large quantity of weapons used to dazzle and attract revolutionaries eager to fight the regime.
In a letter to Haydeé Santamaría and Melba Hernández he instructs then to print and distribute his self-defense during the trial for the events at the Moncada barracks, known as “History will absolve me”, in which reconstruction he tirelessly worked in prison.
- He writes a new letter to Melba and Haydeé warning them about Prioand his followers’ purpose of weakening the ranks of the moncadistas in exile: "The disposition to agree with the Authentics constitutes a serious ideological deviation. If we did not do it before when they had millions upon millions to spear and we were begging for pennies and going through all sorts of hardships to buy weapons, considering them incapable, without morals and without ideology to lead the revolution. How can we now do so, over the dead bodies and the blood of those who gave their lives for their pure ideas? "
Under the title "With political prisoners in Isle of Pines", Fidel's responses to reporter Raúl Martín Sánchez who interviewed him in prison, is published in Bohemia magazine. The article was illustrated with 7 photographs taken in his cell and in the prison library.
He receives in his prison cell of Isle of Pines the unexpected visit of the then Minister of the Interior, Ramón O. Hermida, who comes to apologize after having publicly insulted Fidel.
After the visit, a crisis arises in the Batista cabinet, as Rafael Díaz-Balart scorns Hermida in a public letter. Both resign and Batista intervenes to appease the issue.
- Even while isolated from the rest of his imprisoned comrades, Fidel writes a public letter to Radio Cadena Oriental radio station host, Luis Conte Agüero, excusing himself from the invitation he received earlier that month to join a civic movement. Fidel wrote: "First of all, I must organize the men of the July 26 Movement and unite in indestructible force all the combatants, those in exile, in prison and on the street, which account to more than eighty young people wrapped around the same call to make history and sacrifice. "
- The Castro Ruz family house in Birán catches fire.
- He writes a letter from prison to Moncada garrison combatant Ñico López, who is in Mexico planning to come back to Cuba, with Calixto García Martínez, and who had written Fidel about his plans. In his letter Fidel says: “You must do so publically and appear before court as combatants from the Moncada. Now I explain you why. It is very little what you can do in the streets right now with us still in prison. What I propose to you is worthy of our group and will move public opinion. The proceedings would reopen and we would cause agitation in the country specially now when Batista is about to be officially inaugurated as president on February 24th. It would be a formidable psychological blow at a time when all the voices in the nation are calling for our amnesty. The trial would become the center of the public attention again and a magnificent stands to express our ideas…”
He returns to Mexico City from Merida, Yucatan.
