May 2020  We return in this episode to the Bill Tutte symposium that was held at Bletchley Park in 2017, on the centenary of his birth. Again we bring you one of the many talks given that day, but for the first time in full. Bill Tutte’s breaking of the Lorenz machine led to the Codebreakers at Bletchley Park being able to read the messages being sent between Hitler, the German High Command and the Generals in the field. In his talk our Research Historian Dr David Kenyon, looked at why this was so important to the Allied planners. Focusing specifically on how intelligence derived from Tunny decrypts played a role in D-Day, he asked the question “How Fishy was Ultra?” To find out even more about the work of The Western Front Committee and the planning for D-Day, why not go back and listen to Episode 88 The Tide of Victory, where we looked at this in even greater detail. Image: ©Bletchley Park Trust 2020 #BPark, #WW2, #BletchleyPark, #Enigma, #Tunny
