Summary: references

From time to time I am posting references which appear
to support my thesis that information lost by Germany
through insecure cryptosystems played a vital (perhaps
decisive) role in the campaign on the Eastern Front.

For the Nth time (I am getting tired of explaining this)
I do not endorse any particular reference, or claim that
any single reference proves anything. Read the old postings
before you flame at me for using poor references, OK?

Anyway, I am rereading "The ULTRA Secret" currently.

By the way, someone mentioned the role cryptography played
in Rommel's campaigns. This is a fascinating area, and
fairly well documented. There is a book waiting to be
written examining this question, if anyone is ambitious.

From "The ULTRA Secret", by F.K. Winterbotham
(Dell paperback printed 1982)

Page 187: (Refering to ULTRA intercepts)

"On the Eastern Front the situation reports by the German
commanders showed the relentless Russian pressure now pushing
the German armies back."

[someone had argued that ULTRA was not used to obtain intercepts
 related to the eastern front]

Page 197:

" ... two further armoured divisions, the 9th and the 10th, were
on their way from the Russian front to Caen."

[also, it must be admitted that some German forces were diverted
from the Eastern Front by the attacks of England & the USA. Some
had argued that the Soviets defeated the Germans almost single
handedly.]

"The fact that Hitler was bringing armour from the hard-pressed
Eastern Front to Normandy meant he was now determined to stop
us ..."

Page 207: (refering to von Kluge)

"His record ... in Russia had been good"

Page 210:

"Signals came in showing that the two SS Panzer Divisions
the 11th and 12th, which had come from Poland ... were now
ordered to be kept at Caen."
