Seventy-five years after the Normandy landings, the full scale of Bletchley Park’s top-secret impact on the planning and implementation of D-Day is to be revealed to visitors in a new immersive cinematic experience, D-Day: Interception, Intelligence, Invasion, opening in April.
Featuring a specially commissioned film projected on a 22m screen, the audio-visual experience will run on site in the newly restored Teleprinter Building where hundreds of thousands of intercepted messages first arrived at Bletchley Park from secret listening posts across the UK, and ULTRA intelligence was transmitted to Allied headquarters.
D-Day: Interception, Intelligence, Invasion highlights include:
Direct examples of when BP intelligence altered the Allies invasion plans and helped to save lives.
That on D-Day itself, enemy messages intercepted at Bletchley Park were being decrypted, translated and sent on as intelligence reports in under three hours. This gave the Allied Commanders invaluable insights into how the Germans were responding to the invasion.
The existence of the top-secret Western Front Committee at Bletchley Park, formed in October 1942, who week by week patiently accrued intelligence on the German defences in France which directly impacted on the invasion plans.
How vast the codebreaking operation was at Bletchley Park and its Outstations. By 1944 it had grown from an organisation employing a few hundred people in 1939 to an intelligence factory employing thousands of men and women working in shifts around the clock.
The importance of the Codebreakers breakthroughs into Enigma, but also Lorenz and Japanese ciphers, both of which gave a unique insight into Hitler’s strategy for dealing with the ‘Second Front’.
The race to build machinery to help decipher Lorenz messages that led to the development of Colossus, the world’s first large scale electronic digital computer.
Bletchley Park is delighted to have BT, whose wartime history is closely intertwined with the Codebreaking site, as the Sole and Exclusive Corporate Partner of the restoration of Teleprinter Building and the Exclusive and Sole Partner of the Exhibition. It was General Post Office (now BT) engineers who managed Bletchley Park’s secure communications network.
Working with Bletchley Park, the General Post Office’s research station at Dollis Hill developed codebreaking machines to tackle new ciphers, including Colossus, the world’s first large-scale electronic digital computer.
The Teleprinter Building restoration project has had additional generous support from The Linbury Trust, The Gosling Foundation, The Hobson Charity and The Wolfson Foundation.
Iain Standen, CEO of Bletchley Park Trust said: “D-Day was one of the high points of the Bletchley Park story. 75 years after D-Day, this new experience will allow visitors to understand the vital role ULTRA intelligence played on the invasion plans.”
