On the occasion of VE Day, I recommend this series (it is available on Netflix). It is fascinating and frankly, we often forget how important stopping the heavy water production in Norway was; if the Germans had got the bomb before us, it would have been beyond disastrous. The series certainly has its standard 21st century biases — for example, the Americans are made to look like bullying allies, whereas if you read World War II history, rather the opposite is true.
But the basic facts of the sabotage are there, and I love the portrayals of the Norwegian heroes — men for whom we should be forever grateful and who, in true Norwegian fashion, were ever humble about what they did (a profile of one of them here).
My uncle — his war letters website is here — was being trained to parachute into Norway, interestingly enough. It is possible they were considering him to be part of this project, as he had the language skills required. Either way, the likelihood of survival was slim.
