DZ Season 031 Part 02 German U-Boats in WWII - The Technology War that Dönitz Lost. Final Episode.

After World War 2 Churchill said: "The only thing that really frightened me during the war was the U-boat peril. I was even more anxious about this battle than I had been about the glorious air fight called the ‘Battle of Britain’”. But that wasn’t true. The U-Boat activity, sinking shipping heading to England, was annoying and needed the defences bolstered to counter it, but it was nothing more than annoying. If you know anything about history you’ll probably be thinking I’m joking or stupid. But maybe I’m right. Stay listening and give me the opportunity to surprise you.
