Bletchley Park is known for its work during WWII using highly imaginative technical processes and advanced mathematics to crack the enemy's military communications.
These messages had been encrypted using electro-mechanical devices, such as Enigma and Lorenz. But not all WWII military operatives employed mechanised means to hide the contents of their messages.
Working with the BBC, British secret agents in France pioneered a system to transmit secret messages.
These were called Messages Personnels and their creaton is attributed to Georges Bégué - the first agent in France of Winston Churchill’s then-new Special Operations Executive.
Thousands of Messages Personnels were sent.
Nick Fox, a trustee with The Chicksands Military Intelligence Museum and of Libre Résistance, explains Messages Personnels - and picks three great examples for us.
