The Norwegian Resistance was one of the most successful Resistance movements in WWII.

Norwegian Resistance spotters aided in tracking the movements and securing the destruction of the German battleships Bismarck and Tirpitz.

Norwegian saboteurs destroyed German ships and supplies.

The most famous action of the Norwegian Resistance was the series of raids on the Norsk Hydro Heavy Water Plant, and the attack on the ship transporting 1,300 lbs of Heavy Water to Germany, which knocked out the supplies to the Nazi nuclear program.

The Norwegian Resistance also built up and trained a secret army of 7,000 -8,000 men in Sweden.
