Colossus Cipher Challenge 2 - Hard

Challenge 2 - Hard

This challenge is the second of transmitted cipher texts from the Colossus Cipher Challenge in 2007 where three messages, enciphered by a Lorenz SZ42, were transmitted from the Heinz Nixdorf MuseumsForum in Paderborn, Germany and intercepted at Bletchley Park for Colossus to break. This message is an intercept of 5865 characters on the "Bream" pattern with X2 set. It can be accessed in Virtual Colossus by setting one of the bedstead tapes to "Challenge2" and setting the patterns to "BRpatterns"

For this challenge, you are given the wheel start positions for the motor wheels : M 22,12 only. Your task is to find the CHI AND PSI wheels and decipher.

Hint: You can follow the same procedure as scenario 1 if you want some help!
