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.

The telegram bears on the circumstances surrounding Fidel Castro's controversial 27 October letter to Khrushchev.

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.
