Now you're talking Wayne,great ship,and she was sunk by the one and only, HMS Belfast (one of our superb IWM Museums) who after chasing her and pounding her went in with Torpedoes (along with another ship)to finish her off.She went down on fire and muffled explosions were heard beneath the sea as Scharnhorst exploded under the waves.
HMS Belfast also was the first ship to open fire on the Normandy beaches and remained for many days pounding German forces from offshore,if ever you get chance to visit her she's well worth the trip.
