5. Code breaking

Banbury sheets

Five Photos, Five Stories Challenge

Picture 5/Story 5

I visited Bletchley Park and spent an interesting day immersed in ciphers, codes and Enigma machines.

The picture above is a Banbury Sheet.  It was women’s work to punch holes into the Banbury Sheets according to the Enigma message they had to hand. The trick – as invented by Alan Turing – was to try and find similar sequences on two different sheets, which would suggest that they both have the same Enigma machine setting.

What amazed me was that, at its peak Bletchley Park employed 9000 people engaged in breaking codes for the war effort … and it was a secret that none of them could tell their family or friends.
