I was able to find lots of new information in the government archives of the USA, UK, Germany and Finland and I got lucky with some of my freedom of information act requests to the NSA. Again I have to thank the people who helped me by giving me files and information and/or collaborating with me in locating interesting reports. I wouldn’t have been able to find so much without your help! As we say in Greece ‘η ισχύς εν τη ενώσει’.
Is there
anything left to cover in 2015? Actually there is. I’m waiting for several
TICOM reports to be declassified by the NSA and there also some files from NARA
and the UK national archives that I need to locate/copy. Regarding historical
cases I need to cover:
1). Τhe compromise of the codes of the
Resistance movements in occupied Europe by the Agents section of Inspectorate
7/VI (German Army signals intelligence).
2). The
compromise of the DFC - Division Field Code of the US 29th Infantry Division,
prior to the Normandy invasion in summer ’44.
3). Find more
information on the Polish diplomatic and military attaché codes of WWII (indicator
MILITPOLΟGNE)
4). Continue
to investigate the compromise of the State Departments strip cipher.
5). The
compromise of the communications of General Barnwell R. Legge, US military
attaché in Switzerland during WWII.
6). Add new
information regarding the compromise of the Bell Labs A-3 speech privacy
system.
7). Find more
information on Goering’s Forschungsamt.With a bit of luck I should be able to uncover a great deal of interesting information.
