Well, thanks for the info. But I think you have underestimated
my side of the story. The system wouldn't let me post a response
to your message when I tried, but:

(1). As I said I have read hundreds of books on the subject.
     They are quite consistent with the hypotheses I presented.

(2). The notion of a spy on the general staff was part of the
     effort to hide the source of information.

(3). It is a lot of work to present references, so in a way the
     request for references is slightly unfair. On the other
     hand I certainly can't expect you to accept what I have
     said as proven. But I would ask that you put my theories
     in the "possible" category, and investigate their truth
     if you are interested.

(4). Let me give another reference off the top of my head, since
     I don't have access to the UC library this semester. In
     "Scorched Earth" by Paul Carrels (spelling/title may be a
     little different), a book about the Eastern campaign, the
     author traces the leak of information to the Soviets to
     the very room where encrypted signals were broadcast, but
     never considers the possibility that the cryptosystem was
     insecure. After eliminating almost every other possibility,
     he comes up with a theory that the people sending out the
     info somehow stuck in some extra info about the keys in use.
     (The book was published in the 1950's, I believe.)

Well, anyway, thanks for your interest in the subject. As I said,
although I don't claim I have proved my case, I have done a lot
of work in this area and I have more weapons in my arsenal, but
not a lot of time to argue about it. If you have references for
your side, I would appreciate your sending me a list and where
I can aquire them, if you have time.

Best wishes,

   -Tom

[ps- I will revert to email for the rest of this discussion unless
     someone besides Matt and I is interested.]
