10th Problem - (hint)

War Department,

 

September 1941, the 7th,

 

Dear Mister Friedman,

 

We have decided to adopt a new cipher machine: M-209.
This machine was invented by B.C.W. Hagelin. It is very smart.
In the past, you have already broken several codes. Do you
want to try to break this new machine (M-209) ? If you fail to
do it, we will be conforted by our decision.

 

We can give you some probable words :

discipline, condition, danger, security, military, officer

 

We can also give you any information about the M-209 and
the indicator system.

 

Here they are the messages, good luck !

These messages have been prepared by Mrs Driscoll, the cipher
machine expert from the Navy. A colleague of M
r Hagelin (T.A.) , an
expert of the Swedish C-38, suggested a simpler problem with
several messages  ciphered twice. If the above problem is too
difficult, you can use the following cryptos.
