Signals intelligence and codebreaking played an important role in WWII. British and American codebreakers solved many important Axis crypto systems, such as the German Enigma machine and the Japanese Navy’s code JN25.

1). Articles from Anatoly Klepov on the compromise of Soviet communications in WWII:
I’ve added pics from SRH-368 in WWII Myths - U-boat tankers and ULTRA intelligence.
Best seen under the influence of hallucinogenic drugs.
I’ve rewritten State Department’s strip cipher – reuse of alphabet strips and key lists using information from the report ‘JCS Ad hoc committee report on cryptographic security of government communications'.
On 6 June 1944 the Anglo-Americans landed in Normandy, France and proceeded to liberate Nazi occupied Europe.
2). Normandy 1944 – What-if scenarios and the Fortitude deception
4). The Jellyfish radio-teletype link
6). Book review – Normandy 1944
1). I have uploaded TICOM report DF-169 ‘Cryptanalytic section Japanese Foreign Office’. Acquired through the NSA’s FOIA office.
Imperial Japan entered WWII with three separate codebreaking agencies under the control of the Army, Navy and Foreign Ministry. The Army and Navy signal intelligence agencies intercepted foreign radio traffic and decrypted several military and civilian US, UK, Chinese and Soviet cryptosystems. However relations between these two organizations were strained and in many cases they withheld valuable information from each other. Compared to them the decryption department of the Foreign Ministry was much smaller and had access to limited resources, both in terms of manpower and radio equipment.
This must have been the German Foreign Ministry’s basic codebook used unenciphered for low level messages, enciphered with reusable additive pads for important messages and also with one time pads for the most important traffic.
Series of essays from Anatoly Klepov on the compromise of Soviet communications in WWII:
"Historical truth" Beria and Suvorov about cryptography and radiolocation performance - Conclusion
The history of signals intelligence and codebreaking is usually focused on the achievements of the codebreakers of large countries such as the USA, Britain, Germany, Soviet Union etc. However small nations have often managed to achieve great victories in the field of signals intelligence despite being hampered by limited resources.
Office of Strategic Services requests that US embassy in Turkey pay 10.000 dollars to Albanian minister Dshadshuli
Report on French industry from British ambassador in Switzerland Clifford Norton
US reports from Bern on German war industry
After spending months trying to track down this report I’ve finally managed to get a copy through the CIA’s freedom of information act office.
I have uploaded the report ‘ENGINEERING ANALYSIS OF THE RUSSIAN T34/85 TANK’. Acquired through the CIA’s FOIA office.
Available from my Google docs and Scribd accounts.
I have added tons of new information in WWII Myths - T-34 Best Tank of the war as well as a detailed listing of the sources. Enjoy!
