How was enigma decoded?

Answer 1

The Enigma machine, used by Nazi Germany during World War II, was decoded primarily through the efforts of Polish mathematicians, particularly Marian Rejewski, who initially deduced its workings before the war. This knowledge was shared with British cryptanalysts at Bletchley Park, including Alan Turing, who developed methods and devices, like the Bombe machine, to automate the decryption process. The collaboration of various intelligence efforts and the capture of Enigma codebooks further facilitated the breaking of its codes, significantly aiding the Allied war effort.
