From General Alfred Gruenther to Signal Officer.
We have received several ciphered messages today, but I can't get the
plain text.
Sergent John (nickname : "the Moron"), a young cipher clerk
set the M-209 to the current key this morning and burnt the key list (perhaps
it is the normal procedure). But, he didn't verify the setting with the 26
letters check. Naturally he made mistakes. After that it was impossible for him
to decipher any messages, there were too many garbles.
I know you aren't here because you are inspecting the different message centers
in the vicinity, but it is urgent you come back and help us to set the M-209 correctly
and decipher received messages.
Here is the deciphering of the first message. It is impenetrable.

I asked John to reconstruct the key list from the setting of the
machine (the wrong one). Here it is:
