Colossus and Code Breaking at Bletchley Park

  • Gerard O’Regan


The team at Bletchley Park in England played an important role in breaking the Enigma and Lorenz codes during the Second World War, and their code-breaking work contributed to the defeat of Nazi Germany. The Enigma codes were used by the Germans in the transmission of naval messages to their submarines in the Atlantic and were designed to ensure that any unauthorized interception of the messages would be unintelligible to a third party. The British built a machine (called the Bombe) to crack the Enigma codes, and they developed the Colossus computer to crack the Lorenz codes.
