Geocache Description:

In Memorial Park, Houston , Texas

This cache is NOT at the listed coordinates, but the degrees and minutes are the same.

You goal is to decipher the code to the decimal portions of the cache using an Enigma Machine. (Enigma)


About 1918, Albert Scherbius took his idea of the "rotating rotors" in a cipher machine to the German military. They weren't interested in his ideas at that point in time and so Scherbius took his idea to a German company called Gewerkschaft Securitas. That company bought his patents. The first Enigma machine was produced in the early 1920's. It was an electrical enciphering machine which provided "better" encryptions of messages than other machines at the time because of the rotating rotors. The German Navy started buying Enigma machines in 1925 and they started to modify it. The German Army soon followed suit and they also modified the machine. Some of the modifications included adding or deleting some keys, the addition of the plug board and using more than three rotors. The Germans placed a lot of confidence in the security of the Enigma machine because they thought that the probability of breaking a message would be too great for their enemies. They did have certain procedures on the operation of the machine. The Germans had manuals that the operator used to set the parameters of the machine for each day. Contrary to the beliefs of the Germans, the Enigma machine was not secure. In 1928, the Poles acquired the knowledge about the German military Enigma by intercepting one, in customs, being sent to the German Embassy in Warsaw and examined it. A whole series of Enigma machines was produced at the factory in Warsaw. A group of brilliant mathematics students at the Poznan university (Rajewski, Rozycki and Zygalski) was recruited to work in the cryptological section of the Polish General Staff. By 1934 they decrypted the German Enigma signals. To facilitate decryption Rajewski designed an electromechanical programmable machine which he called 'Bomba' (Polish for bomb) because of the bomb-like ticking noise it made. On July 25, 1939, the Poles gave the French and the British replicas of Polish made Enigmas together with the drawings and information on the Enigma, Bomba and the decryption information.
