Polish code breakers were able to read German messages in 1932 long before the outbreak of war in Sep 01 , 1939 which was the reason of passing vital information to British and French . Names of Polish experts are - Marian Rejewski , Jerzy Rozycki and Henryk Zygalski with many others who contributed to the project of cracking the “Enigma “ - most sophisticated coding mashine of that time .
Also, some credit goes to the Frenchv they were the ones who found a disgruntled German officer who wanted to switch sides and stole one Enigma, passing it to the Poles, as they didn't really know what to do with it.
RRZ (Rejewski, Różycki, Zygalski) were educated under the Prussians - in German - and they had the knowledge and experience that no-one else could have provided in the 1930's. Touring provided the theory that RRZ didn't.

Excellent breakdown and description. The first time this has made sense to me. Thanks. Good work.
I had the opportunity to stand on Omaha beach, Dog Green sector. My feelings were enhanced from watching your Walking D-day series. Thank you.
Exceptionally clever people. I struggle with crosswords.
Very enlightening and a job well done. A simple explanation for a very complex machine.
First....it was the Polish men....Then....it was Alan Turing....Problem solved....
Well done
