In my recent essay on The ciphers of Czechoslovakia’s government in exile I mentioned a report titled ‘Dopady lúštenia šifrovacieho systému čs. londýnskeho MNO z rokov 1940-1945 na domáci odboj’.
This report had information on the compromise of Czechoslovak communications and the impact on resistance activities.
It has taken me some time get a copy but thanks to my friend Jozef Krajcovic I finally have the report.
I will soon add some of this information in my essays on Czechoslovak ciphers.
