Communication is the key to conducting effective and precise operations at sea. The primary means of transmitting information on the U-boat is Enigma - a device for encrypting and decrypting messages.
During missions, the headquarters often communicates with us - radio operators receive encrypted messages.
On board, there is a diary of Enigma daily codes - the keys needed to decrypt the message received on a given day.
Enigma is located in the officer's quarters - this is where strategic messages are transmitted, the current state of operations is reported, and we receive key information about enemy ships or aircraft.
Enigma has a rotating disc on which the correct daily code must be entered - then we give the order for one of our crew members to take care of it, and after a moment we can read the decrypted message.
If not for this information, we would have fallen into a trap - we did not know that the merchant ship on AN 93 had support!
I wonder what we will receive in the message the next day - hopefully, we won't hit any mines...
