Operation Gunnerside
On the evening of February 27, 1943, nine Norwegian commandos infiltrated the German-held Vemork plant, a hydroelectric plant owned by Norsk Hydro just outside of Rjukan, Norway. Their mission was to destroy the water pipes in the basement of this plant. Although these commandos did not know the significance of their sabotage at the time, they later learned that their mission played a part in hindering Germany’s atomic bomb program.
