Joachim Ronneberg, a Norwegian commando who helped cripple a Nazi occupied heavy-water facility in Norway, died in late October. He and his fellow commandos were stranded in the mountains of Norway because of equipment failures. Radio contact with the outside world was spotty and was unwise because transmissions could be intercepted by the Germans.
The challenges were immense, but the commandos persevered and reached the plant in Telemark.

There is a great documentary about the raid on YouTube. It is a three part series. I could only find part one and two in complete videos. Part three can be watched in ten minutes chunks.
