In late February 1943, Norwegian commandos were given the details of their mission, Operation Gunnerside. Their job would be to sabotage the Vemork heavy water facility in Norway, hindering German industry and their development of the atomic bomb. Before they left, Norwegian Royal Army Colonel and pioneering chemist, Leif Tronstad, told his soldiers, “I cannot tell you why this mission is so important, but if you succeed, it will live in Norway’s memory for a hundred years.” Fully aware of the danger they faced, the men were handed suicide pills in case of capture. On the 80th anniversary of this daring raid, Dan is joined by the survival expert and TV presenter Ray Mears to discuss the challenges they faced, and the consequences of their mission.
