The Sunken Mystery of the Lost U-Boat 455

This documentary follows the discovery of U-455, a lost German submarine from the Second World War, resting intact off the coast of Italy. For marine archaeologist Lorenzo del Veneziano, the sight of the U-boat standing almost upright at great depth is extraordinary. The film explores the mystery of how the vessel sank and what became of its crew. Atmospheric and absorbing, it dives into a haunting wartime enigma. Free to watch in HD on Dr Documentary.
