As a postscript to Teribus's footnote about the escape of Denmark's Jews, there was a TV documentary here a few months ago about the subject. It appears very likely that there was a tip off about imminent round up of Jews, which came from a humane member of the German embassy. The news was leaked in time and most of them got out in small boats before the round up began. It is one of the more heartwarming stories I have heard among all the human disaster, which was the Second World War.
