Chargé d’Affaires ad interim Erzsébet Görög writes a preliminary assessment of Castro’s state visit to the Soviet Union in 1963. Görög reports on improvements in Cuba’s party organization and positive reactions from the Cuban public and media on Castro’s visit. Görög notes different reactions to the visit between the economic/technical and artistic intelligentsia, adding that “Khrushchev managed to win Fidel over to his side in the Soviet-Chinese dispute.” Other topics include emigration and external counter-revolutionary activities.

Boissevain reports on Fidel Castro. During a banquet held by the Egyptian ambassador, Castro speaks to Swiss Ambassador Masset of a decision to nationalize the former building of the U.S. embassy, currently in use by the Swiss embassy acting as U.S. representatives. Castro is noted as having "the air of one who is boasting to a trusted friend about how he has crossed an opponent." Boissevain thinks it best to keep on Castro's good side and requests an illustrated work of the Netherlands to be sent as a gesture of goodwill.

Pinto discusses the current situation in Cuba and feels certain that Cuba depends more and more on Soviet economic help, but that Fidel Castro feels sure of that there will only be an overthrow due to an American invasion or by a prolonged total blockade, that will have more grave international implications.

The telegram bears on the circumstances surrounding Fidel Castro's controversial 27 October letter to Khrushchev. Alekseev describes Castro's demeanor as being irritated and paranoid at the time of writing the letter. He provides background on Castro's actions and attitudes at the peak of the crisis, and especially his nocturnal visit to the Soviet embassy and preparation of his letter to Khrushchev on the night of 26-27 October. He advises Moscow on how to handle the Cuban leader, and offers analysis into the emotions and overall mood of Castro and his associates at that moment in the crisis.
