Though Guevara had returned to Cuba on March 14, 1965, his absence from public functions soon excited comment and, as the months went by, became an international mystery. Finally, on October 3, during the televised ceremony of the presentation of the newly established Central Committee of the Communist Party of Cuba, Castro, in the presence of Guevara's wife and children, read the following letter. Castro explained that the letter had been delivered to him back in April and that Guevara had left the timing of its disclosure to Castro's discretion. He had delayed so long in making it public out of concern for Guevara's security and, for the same reason, could not divulge his present whereabouts. * * *
Fidel: At this moment I remember many things -- when I met you in Marfa Antonia's house, when you suggested my coming, all the tensions involved in the preparations.
One day they asked who should be notified in case of death, and the real possibility of that fact affected us all. Later we knew that it was true, that in revolution one wins or dies (if it is a real one). Many comrades fell along the way to victory. Today everything is less dramatic, because we are more mature. But the fact is repeated. I feel that I have fulfilled the part of my duty that tied me to the Cuban Revolution in its territory, and I say good-bye to you, the comrades, your people, who are already mine.
I formally renounce my positions in the national leadership of the party, my post as minister, my rank of major, and my Cuban citizenship. Nothing legal binds me to Cuba. The only ties are of another nature -- those which cannot be broken as appointments can.
Recalling my past life, I believe I have worked with sufficient honor and dedication to consolidate the revolutionary triumph. My only serious failing was not having confided more in you from the first moments in the Sierra Maestra, and not having understood quickly enough your qualities as a leader and a revolutionary. I have lived magnificent days, and I felt at your side the pride of belonging to our people in the brilliant yet sad days of the Caribbean crisis. Seldom has a statesman been more brilliant than you in those days. I am also proud of having followed you without hesitation, identified with your way of thinking and of seeing and appraising dangers and principles. Other nations of the world call for my modest efforts.
