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.

The report introduces Czechoslovak's assistance in the Operation MANUEL after the isolation of socialist Castro regime. Cuba looked for alternative routes in Europe in order to promote and influence the revolutionary movement in Latin America. Czechoslovakia assistance in the operation is of a strictly technical nature and its intelligence service is doing its utmost to protect the interests of the country by securing all technical matters. The report says that terminating the assistance was not possible for both practical and political reasons-- all direct flights between Czechoslovakia and Cuba would be suspended and a drastic cooling off of relations between two governments. Czechoslovak's refusal in assisting the operation would be interpreted as a political decision to suspend assistance to the national liberation movement in Latin America countries. However, the reports says that the assistance of Czechoslovak intelligence service to the operation is in no way amounts to agreeing with its political content and constitutes a minor aspect of intelligence work. The Soviet intelligence was also involved in organizing the operation in Moscow and offered assistance to its Cuban counterpart.
