Not to take anything away from the Danes - but I've read that the story of the Danish royal family (not to mention the rest of the populace) wearing the yellow star is folklore. Any authoritative source to the contrary?

"a tip off about imminent round up of Jews, which came from a humane member of the German embassy"

Hannah Arendt in Eichmann in Jerusalem says the German officials who were stationed in Denmark and in Bulgaria, which also refused to co-operate with anti-Semitic measures, tended to soften their own views over time, and begin to drag their feet enforcing the anti-Semitic edicts from Berlin. In fact, probably the most damning evidence against Eichmann concerned a trip he made to Bulgaria to whip his underlings into line, because they were not carrying out his anti-Semitic directives with enough rigor.

By the way, for anyone with the remotest interest in this stuff, Eichmann in Jerusalem is a must-read.
