From "Alan Turing the enigma" by Andrew Hodges,
      Simon and Schuster, 1983 (hardcover)

(The above book I found to be extremely interesting, and well
 worth reading.)

(By the way I hate the word "cryptology". I have never been
able to get used to it. I grew up with the word "cryptography"
and am too used to it to change. I think the new terminology
has some point to it, but I also think it introduces a new
level of jargon into the subject that doesn't really serve
to aid a deep understanding. In fact I am inclined to think
it was introduced by mediocrities who had nothing better to
contribute to the field.)

[refering to Hitler's invasion of the Soviet Union: (page 205)]

"the Luftwaffe Enigma evidence pointing to an imminent German
invasion had been the subject of another fight between GC and CS
on the one hand and the service chiefs on the other."

[refering to which German cryptosystems were subject to
attack: (page 218)]

"... at GC and CS they had established a principle of attacking
everything, however apparently insignificant ..."

[page 237]

"... by 1942 Bletchley Park was no longer outside the ordinary
channels: it dominated them. Its productions were not the spice
added to some other body of knowledge. It was nearly all they
had - photo reconnaisance and POW interrogation adding points of
important detail but never matching in scale what they had fresh
from the horses mouth. There were sixty key systems broken, producing
fifty thousand decrypted messages a month- one every minute. The
old days of 'Red' and 'Yellow' were long over and the soaring
imagination of the analysts, exhausting the colors of the rainbow,
had plundered the animal and vegetable kingdoms: Quince for the
SS key, Chaffinch for Rommel's reports to Berlin, Vulture for
the Wehrmacht on the Russian front."

[In cased you missed it, I quote again: "Vulture for the Wehrmacht
ON THE RUSSIAN FRONT"]

" ... except for [certain] gaps, the German radio communication
system had become an open book ..."

[pages 237-238]

" ... the setting of agents, the suborning of informants, the
sending of messages written in invisible ink, the masquerading,
the dressing up, the secret transmitters ... all turned out to
be largely cover for [ULTRA] ... "

[page 238]

"Who was to know what ... ? Liason with
[the Americans] was just one problem; there was the deception
of Dominions, free forces, and Russians"

[I repeat RUSSIANS]

[page 239]

" ... was allowing Soviet authorities access to Enigma decrypts."
