I should have known this: today is the 70th anniversary of the attack by Germany on Norway and Denmark, in 1940.
Mitch Berg (who, I’m embarrassed to admit, knows the subject far better than I) tells the story here.
Norway thus became the only country conquered by Hitler to never surrender to the Nazis. Haakon, leading Norway’s legitimate government (no country ever recognized, even by the dubious standards of world diplomacy, Vidkun Quisling’s puppet regime) at the head of over 20,000 troops in exile, 50,000 troops in the underground, and the 22,000 men and hundreds of ships of Norway’s merchant marine.
