(grin). Actually, the Scharnhorst and the Geneisenau were considered to be full-fledged battleships. The pocket battleships were the Admiral Graf Spee, the Admiral Scheer, and the Lutzow (formerly the Deutschland).
The difference was in displacement, main battery armaments, and armor. The pocket battleships had significantly lower displacements (about the same as heavy cruisers) and had only 6 nine-inch guns in the main battery. The Scharnhorst and the Geneisenau had 9 nine-inch guns. The heavy cruisers of the era had eight-inch guns, so the difference is somewhat a matter of judgement or semantics.
D'OH!
That always happens when I pretend I know what I'm talking about.
I have been following WWII in real time + 60 years on a cool website called worldwar2.net. It was in Feb. 42 that the two FULL SIZED battleships eluded the Royal Navy and made it to safety in Kiel and Wilhelmshaven.
On 5 April 42 the Japanese are closing in on Bataan and the British lost several ships in action off Ceylon. Not a happy time for the Allies.
