The Saboteurs of Vemork: How One Team Stopped the Nazi Atomic Bomb

In the icy wilderness of Norway, high on a snowy mountain, stood the Vemork Hydroelectric Plant — the only facility in Europe producing heavy water (deuterium oxide), a critical component for Nazi Germany’s nuclear weapons research.

If the Nazis succeeded in building an atomic bomb, it would’ve changed everything. But in 1943, a group of Norwegian resistance fighters, trained by the British SOE, pulled off one of the boldest sabotage missions in history.

The man at the heart of it? Joachim Rønneberg, a 23-year-old Norwegian who led Operation Gunnerside.

Here’s how it went down:

  • Rønneberg and five other commandos parachuted into Norway in the middle of winter, landing miles from the target in freezing darkness.

  • They skied for days through snowstorms, across mountains and forests, carrying weapons, explosives, and barely enough food.

  • Once they reached the area, they coordinated with local resistance, studied guard routines, and waited for the perfect moment.

On February 27, 1943, under cover of night, they snuck into the heavily guarded facility, crept through a ravine, climbed a sheer cliff wall, and entered through a cable shaft the Germans thought was inaccessible.

Once inside, they planted explosives on the heavy water equipment and — here's the twist — left behind a British-made time pencil fuse, intentionally, to prove it wasn’t an inside job and protect local workers from Nazi reprisals.

The plant was destroyed, the German nuclear program was set back by years, and the team escaped without a single shot fired.

The Nazis tried to restart production, but later attempts were again foiled by Allied bombing and another sabotage mission. Hitler’s nuke program never recovered.

Rønneberg lived to be 99 and said later in life:

“We didn’t think about being heroes. We just knew it had to be done.”
