About this programme

13/26. How British-trained resistance fighters infiltrated the Norsk Hydro electrochemical plant in occupied Norway in 1943 and destroyed the Nazi installation, which was dedicated to producing an atom bomb. The freedom fighters, code-named Gunnerside, entered the heavily guarded plant by scaling sheer rock faces thought to be unclimbable.
