During World War I, German U-boats had been the most effective naval weapon against the Allies and without America's entry into the war in 1917 Britain would have been starved into surrender.

And this is the story of their part in the war, focusing in particular on the role of the wolf pack of U-boats in the Atlantic, whose stealthy presence beneath the waves ensured that British merchant ships were dicing with death every time they put out to sea

During the last six months of the war, it seemed obvious the Germans had been crushingly defeated, but in spite of the military situation, Hitler continued to believe that victory would be achieved. He repeatedly told his advisors and inner circle that Germany possessed Wunderwaffen - miracle weapons - that would turn the tide and give the Germans victory. This is the story of the weapons that, if given the chance, could have won the war: Nazi flying saucers, the V-1 flying bomb, the V-2 rocket, and the V-3 heavy gun, as well as the Nazi nuclear program, and much more.
