As the Allies pressed forward both in Europe and the Pacific in the waning days of World War II, a little known battle took place under the frozen seas off the coast of Norway…and changed the course of the war.By February of 1944, both Germany and Japan were falling back under constant attack from Allied forces. The end would have been inevitable, if not for a desperate, audacious plan by the German High Command.The Germans would pack a submarine boat U-864 with their most advanced rocket and jet aircraft technology, a group of Japanese and German scientists, and tons of mercury for use in missile and torpedo detonation systems. With this, Japan could re-establish air superiority in the Pacific, forcing the Allies to divert troops and material long enough for Germany to re-group and prepare a final defense of the Fatherland.
