On 26 July 1962, a Soviet armada departed from Odessa bearing 44,000 troops and six atomic bombs, along with eighteen nuclear cruise missiles, three divisions of tactical nuclear weapons and six bombers. In August they started installing the missiles: it is likely Khrushchev permitted his commander to use the tactical weapons – if necessary. American intelligence noticed activity in Cuba but had missed massive activity in Odessa and never realized the full extent of the Soviet deployment.[*13]
