The Poles had received the wiring diagrams for Enigma from the French Secret Service in 1932 and were able to consistently break Enigma shortly thereafter.<ref>Hodges, A. (1983). Alan Turing: the enigma. Vintage. pp 170.</ref> The Poles used the indicators transmitted at the beginning of every message to search tables of all possible rotor combinations to determine what was in use. This manual process was time consuming so the Poles created a machine with Enigma rotors that searched these 6 x 17,576 core combinations for them. The downside of this was that each of the six possible rotor orders required its own machine. When the Germans introduced two more rotors to be used which brought the possible rotor orders up to 60, the Poles did not have the resources to build 60 machines to search for the combinations.<ref>Hodges, A. (1983). Alan Turing: the enigma. Vintage. pp 172-174.</ref> It was at this point that they passed their information onto the British and French. Alan took these ideas developed by the Poles <del class="diffchange diffchange-inline">for </del>an automated machine to search instead of a human. The big problem was, how do you incorporate so many physical combinations into a machine and have it know what it is searching for. The basis came from using a crib, a likely plain-text message, to compare against the encoded Enigma message. A major part of the Enigma machine was that it used a reflector which gave it a special property that no letter can encipher itself. Trying to find the exact location of a crib was made possible by this because if any letter lined up with itself then that could not be the correct position. This same phenomenon would be the basis for the Bombe machine and its search method as this contradiction helped eliminate possible plugboard combinations and make it feasible to solve.<ref>Hodges, A. (1983). Alan Turing: the enigma. Vintage. pp 179.</ref> It was a brilliant design by Alan Turing, but when Gordon Welchman saw the designs he saw a way to exploit Enigma even more. His ideas that are explained below made the Bombe machine designed by Turing practical.<ref>Hodges, A. (1983). Alan Turing: the enigma.

The Poles had received the wiring diagrams for Enigma from the French Secret Service in 1932 and were able to consistently break Enigma shortly thereafter.<ref>Hodges, A. (1983). Alan Turing: the enigma. Vintage. pp 170.</ref> The Poles used the indicators transmitted at the beginning of every message to search tables of all possible rotor combinations to determine what was in use. This manual process was time consuming so the Poles created a machine with Enigma rotors that searched these 6 x 17,576 core combinations for them. The downside of this was that each of the six possible rotor orders required its own machine. When the Germans introduced two more rotors to be used which brought the possible rotor orders up to 60, the Poles did not have the resources to build 60 machines to search for the combinations.<ref>Hodges, A. (1983). Alan Turing: the enigma. Vintage. pp 172-174.</ref> It was at this point that they passed their information onto the British and French. Alan took these ideas developed by the Poles <ins class="diffchange diffchange-inline">to create </ins>an automated machine to search instead of a human. The big problem was, how do you incorporate so many physical combinations into a machine and have it know what it is searching for. The basis came from using a crib, a likely plain-text message, to compare against the encoded Enigma message. A major part of the Enigma machine was that it used a reflector which gave it a special property that no letter can encipher itself. Trying to find the exact location of a crib was made possible by this because if any letter lined up with itself then that could not be the correct position. This same phenomenon would be the basis for the Bombe machine and its search method as this contradiction helped eliminate possible plugboard combinations and make it feasible to solve.<ref>Hodges, A.

This had advantages, but it did also have its drawbacks. Since it was radio signals the enemy could intercept them. To protect the messages they needed to be enciphered. In the 1920s, a German Engineer named Arthur Scherbius designed many different cipher machines. He settled on a design and called it Enigma.<ref>Churchhouse, R. (2002). Codes and ciphers: Julius Caesar, the Enigma, and the Internet. Cambridge University Press. pp 111.</ref> This original design for Enigma was based upon a 26 letter keyboard for inputting the plaintext message, 26 lamps to show the cipher letters, a power supply, three removable wired wheels that rotate around a common axis, a fixed reflector, and a fixed entry wheel. This setup introduced two important features; no letter can encipher itself, and there is symmetry of plain-cipher pairs, ex. if J enciphers M, then M enciphers J.<ref>Churchhouse, R. (2002). Codes and ciphers: Julius Caesar, the Enigma, and the Internet. Cambridge University Press. pp 112-115.</ref> This scrambling of letters would have been the equivalent of a complex substitution cipher if the wheels didn't move, but they did. Whenever a key was pressed a mechanical mechanism advanced the wheel one position, so after 26 key presses the first wheel would return to its starting position. At this point the second wheel would then turn, and once that wheel made a full rotation then the third wheel would turn. This rotating mechanism made the enciphering process very complex as all three wheels would not have returned to their original positions until 16,900 letters would have been enciphered.<ref>Churchhouse, R. (2002). Codes and ciphers: Julius Caesar, the Enigma, and the Internet. Cambridge University Press. pp 119.</ref> This rotating motion made deciphering difficult, but several other parts of the machine made things even more sophisticated. One of these was the option to take off the three wheels and reorder them in six different ways, this produced 101,400 different substitution alphabets. To add even more of a challenge for anyone trying to decrypt the messages, the rotors could be started in any one of the 26 positions which created 105,456 possible starting positions and substitution alphabets, and that's with having an Enigma machine which allowed one to know the wiring.<ref>Churchhouse, R.
