Dear FOB, Indeed, transpositions and bad spelling often caused problems for code-breakers especially with the spies sending messages under the duress of combat conditions encountered in WWII. Again, I plug "From Silk To Cyanide" where this discussed in depth with personal experience by author Marks (who was a mere stripling at the time.). ALERT: this is not yet another book about the Enigma machine at Bletchley (sp?) but a different, English, operation. The code-breakers Marks worked with were all women, for one thing! 'Nuff said.
wow
