  • Good evening!  Thank you for your reply.  I just emailed the archives2 address with specific requirements.  

    Thank you again!

  • Good afternoon,

     
    Many thanks for your reply.  Here is what I am specifically researching:
     
    -- From what I can tell the OSS had no human sources operating on the ground in Japan during WW2.  (For example, the Soviets had Richard Sorge collecting intelligence on the ground in Japan.  I am trying to dig up as much as I can on this matter.  
     
         - I would welcome OSS operational files concerning assets, sources, developmental relationships, recruited sources with code names operating in Japan and providing reporting.
     
         - I would welcome any details on recruitment operations (successful or unsuccessful) of HUMINT sources operating one the ground in Japan.
     
         - I would welcome raw and finished intelligence on Japan.  This could provide us with some threads to pull regarding the sources, if any.  I suspect most reporting was from intercepts.
     
         - I would welcome OSS files on human penetrations of the government of Japan and military including the High command and imperial family.
     
         - Lastly, I would welcome OSS operational files concerning human sources reporting on Japan who were operating outside of Japan, or were recruited outside of Japan.
     
    Many thanks in advance!
     
    Best wishes,
    Raymond W
