Ulbricht speaks at the Moscow Conference of Secretaries of the Central Committees of the Communist and Workers' Parties of Socialist Countries for the Exchange of Opinions on Questions Concerning the Preparation and Conclusion of a German Peace Treaty.

Protocol 60 details the first meeting of the Communist Party during the crisis. As Khrushchev is awaiting the announcement by President Kennedy of the discovery of missiles in Cuba, he and some of his colleagues briefly considered using tactical nuclear weapons in the event of a US airborne assault. But, at the suggestion of Soviet defense minister Rodion Malinovsky, the Kremlin postponed its consideration of a nuclear response pending details of Kennedy’s speech.The Kremlin wasted no time in taking steps to reduce the risks of confrontation. It ordered some ships that were still in the Mediterranean to turn around. The Aleksandrovsk, the ship carrying the nuclear warheads for the IRBMs (the R-14s), was ordered to keep sailing, however, because it was close enough to Cuban shores to dock before the blockade went into effect.

Letter from Gomulka to Khrushchev discussing Polish opposition to Soviet proposal for a Non-Proliferation Treaty. Gomulka suggests that the treaty will further split the communist camp. While discussing the state of Sino-Soviet relations, the Polish leader suggests that the Soviet Union and the PRC adopt a common position in matters of foreign policy in order to strengthen the power of the Socialist camp.
