On 5 February 2014, TNMOC celebrated the 70th anniversary of Colossus, the world's first electronic computer. In 1944, Colossus Mk I made its first attack on a German Lorenz-enciphered message at Bletchley Park, Buckinghamshire, UK. In 2014, Colossus veterans, their relatives and guests watched a re-enactment of the breaking of Lorenz from intercept to decrypt.
