The Secret War

The Deadly Waves

The account of how the British scientific effort to discover and counter a dangerously effective new kind of Nazi Germany magnetic naval mine.

Still Secret

Discussed are the efforts to break the Enigma Code and the role played by the Colossus computer, designed by T.H. Flowers. In 1977 the Colossus was still on the secret list, so details are fairly sparse, but the programme benefits enormously from an interview with Tommy Flowers. There are also valuable contributions from others present at Bletchley Park during WW2 such as Gordon Welchman, Harry Golombek and Peter Calvocoressi.

The Battle of the Atlantic

The technical and tactical innovations that developed in the vital naval battle of the Eastern Theatre of World War II. This was an extra on the VHS release of this series.
