If that facility is Vemork Norsk Hydro Plant, one would think that all they had to do was bomb the facility or just the roads leading to it........
Looking at the photo, and knowing the steep terrain in Norway, I’m guessing that the bombing technology of the early 1940’s wouldn’t lend itself too well to that type of target. Flying along at xxx mph, but only see the target when you are within a mile of it, etc.
My dad’s cousin was in the Norwegian underground. He became a very successful businessman in Norway. My dad asked him what he did in the underground.
“Even my wife doesn’t know. I will go to my maker with my secrets.”
However - his story of how he evaded capture in the first place sounds a lot like the beginning of a favorite childhood book of mine. Snow Treasure.
The kids help to smuggle tons of gold out of Norway on their sleds. Great story - a true story. Sledding right by the German soldiers. Some of the soldiers even wanting to be friendly. “Seeing us having fun must have brought up thoughts of their own children.”
One of the older boys in the story hides under the pile of potatoes in the cellar. IIRC my dad’s cousin hid under the pile of coal in the cellar when the Germans entered his town. Or maybe it was potatoes as well. I’ve always wondered.....
BTW - Norway at the time had gun registration. The first thing the Nazis did when entering a town was to get the gun registration documents, and then go to those homes to get the men and guns.
