DETAILS:


 * The summary was originally prepared for the Director on 10-26-50 and it was designed to give an over-all view of the MGB (Soviet intelligence) based on information by [Venona project].  This source has been able to furnish us information regarding MGB operations in the 1940’s.  The main limitations on this information are that in many instances it is fragmentary and further, the Soviets extensive use of code names had made identifications difficult.


 * Based on the investigations from [Venona project] information we have identified 206 persons involved in Soviet espionage activities who have at one time been active in the United States or which activity has had some United States ramifications. Of this number we already had received information from other sources including espionage involvement on the part of 87 of these persons.  However, 119 persons were not previously known to us as being involved in espionage and have been identified through investigation in this case.

A chart explaining these figures in more detail is set out.
