Geocache Description:

Crumlin Cipher Cache number 4.1

Koordinaterne i denne serie af cacher er ikke koordinaterne på selve cacheboksen, men på en bekvem parkeringsplads i nærheden. For at finde cachen skal man dechifrere en kodet meddelelse hvor den resulterende tekst er på engelsk. Det kan også blive nødvendigt at søge visse informationer på internettet. Da disse informationer næsten udelukkende findes på engelsk, så er man nødt til at kunne læse og forstå engelsk. Resten af cachebeskrivelsen er på engelsk, men man kan få en oversættelse ved henvendelse til cacheejeren.

This is a Mystery/Puzzle cache. The coordinates of this cache are not the coordinates of the cachebox, but they will lead you to a convenient parking area.

The cachebox is a 2 liter cylinder hidden near “Krogerup Højskole”. It contains a logbook, a pencil, a FFC and some trading items.

Prior to World War II, the British and French military had given up breaking the German Enigma machine. With the progress of the Polish mathematicians, the British finally set up a team of cryptanalysts in Bletchley Park for the purpose of cracking the German Enigma communication.

In 1939 Alan Turing was recruited to Bletchley Park. Together with another mathematician W G Welchman, Turing developed the Bombe, a machine based on earlier work by Polish mathematicians, which from late 1940 was decoding all messages sent by the Enigma machines of the Luftwaffe. The Enigma machines of the German navy were much harder to break but this was the type of challenge which Turing enjoyed. By the middle of 1941 Turing's statistical approach, together with captured information, had led to the German navy signals being decoded at Bletchley.

The ciphertext below is enciphered using a 3-wheel Enigma machine setup with “Reflektor” B and “Ringstellung” AAA and the Puzzle is to decipher it in order to get the plaintext leading to the cache. The Mystery is how to find the remaining settings. This cache is different from CCC#4 in the sense that you cannot find the rest of the settings anywhere, but this time you have a good chance of guessing the start of the plaintext, a "crib", containing the coordinates and to find a Bombe to crack it.
