Um, a Freiherr from Silesia is only marginally Prussian I think, albeit one of ‘ancient’ lineage. Could well be wrong about that. Also, RB could well have kicked back against Goering who was a real piece of work even before Nazism. Might even have succeeded due to hero status with the general public of Germany. Much more liked and admired than Goering. As you said, we’ll never know for certain sure. Which is probably a good thing.
