Ray Mears shows how the success of a vital World War II mission depended on survival skills.

Sixty years ago, four men parachuted onto a Norwegian glacier, carrying only the most basic equipment. Their mission was to prevent the Nazi regime from building an atomic bomb. Now wilderness expert Ray Mears tells the true story of this gruelling campaign, showing how these men's ability to survive in extreme conditions influenced the outcome of the Second World War.

The Telemark campaign was an example of the bravery and skill of the SOE trainees. The Norwegians transformed a military disaster into a triumph. This book tells the full story for the first time.

"If Ray Mears isn't a Great Living Englishman, then goodness me, who is? The man is great, and he doesn't even begin to know how great he is. Ray is a persuader, pragmatist and populariser in the Durrell-Attenborough-Bellamy tradition." - Robert Crampton, The Times Magazine

"Ray Mears is a bushman first and foremost and really can survive in any extreme environment. I can't think of a better companion in a crisis." - Tim Lewis, GQ

"The foremost purveyor of bushcraft in the UK today." - Geographical Magazine
