Ciphers and codes of the Czech Maffie (1914-1918)

Maffie was czechoslovakian (eventually, Slovaks was involved later) resistance movement, mostly conspiratorial organisation, against Austrohungarian monarchy. It was used espionage, smuggling news from outside world, mostly from belligerent nations, such as France, Great Britain, US and to disseminate new ideas of democracy and citizen’s liberty to the society.

Was used mostly on the basis of the Alberti disk (from the book The Cryptographic front, p.63)
