In a single different obstacle, he moreover used symbols that indicate nothing to mislead any adversary trying to decipher the message.
The breakthrough received right here in June, when Pierrot managed to make out a phrase throughout the letter, and the workforce then cracked the code with the help of historian Camille Desenclos.
