The usual historical narrative of the U-boats during WWII usually revolves around the 'Battle of the Atlantic', and the struggle over the convoys bringing vital supplies to Britain.  But the story of the U-boat war is much more complex, they went into action on the first day of hostilities with Britain and France and operated in nearly every theatre of operation in which the Wehrmacht served, and within all but the Southern Ocean.  To discuss the global U-boat war I am joined by Lawrence Paterson, author of The U-Boat War: A Global History 1939–45.
