This page includes various examples of real, contemporary Enigma messages (collected from several sources, acknowledged [[#Acknowledgements|below]]). You can decrypt these with the [http://market.android.com/details?id=uk.co.franklinheath.enigmasim Enigma Simulator app] (see the [[Enigma/Simulator User Guide|User Guide]]).
__TOC__
The plain text of the messages is of course in the German language, and may include abbreviations and conventions such as "X" for breaks between words or sentences or "J" for a quotation mark, so further interpretation and translation will be needed to produce an understandable message in English. The decrypts and translations are on [[Enigma/Sample Decrypts|another page]] if you would like to check your results.
