        I april i år hittade en grupp brittiska skattsökare en kista i ett postrum i vraket av SS Minden. De tror att kistan innehåller just det guld som fick nazisterna att sänka fartyget när det upptäcktes av de allierade.

        In April this year, a group of British treasure hunters discovered a chest in a mailroom within the wreck of the SS Minden. They believe the chest contains the very gold that led the Nazis to scuttle the ship when it was detected by Allied forces.
