Overview
D-Day Decrypts

The Bletchley Park Trust holds a unique collection of almost 250 German naval Enigma messages from the time of the Normandy landings launched on D-Day, 6 June 1944. Having provided invaluable intelligence for the planning of the invasion, the Codebreakers also supported the operation as it unfolded. Messages were intercepted, deciphered and translated in as little as two-and-a-half hours.

To mark the 75th anniversary of D-Day, this Thursday 6 June 2019, Bletchley Park will be live tweeting, in real time, messages intercepted on 6 June 1944. Follow the ‘Twitter Takeover’ here.

You can delve deeper into some of the messages sent on 6 June 1944 in the album below. Reading these messages today it is possible to follow the events of the day from the perspective of the German navy (Kriegsmarine), as initial confusion gave way to realisation of the scale and importance of the unfolding invasion…

D-Day Decrypts
1 / 10The first message in the collection indicates German commanders’ first inkling of what was taking place, with a command ordering “immediate readiness”. The 2nd Security Division based in Boulogne was responsible for the light gunboats, minesweepers and patrol boats tasked with defending the Normandy coast. It is unclear what triggered this warning, but it is likely reports of increased naval activity and the first parachute landings had been received.
