Operation Gunnerside

• Began February 1943

• A small team of British-trained Norwegian exiles parachuted onto a frozen plateau near the Norsk Hydro Vemork plant in Norway.

• February 27, the Norwegian commandos skied to the Norsk Hydro site, descended a gorge, forded an icy stream and made a difficult climb to the outskirts of Vemork.

• The men then entered the plant through a cable duct and planted explosive charges on the heavy water chambers.

• As the crew made their getaway, the bombs detonated and successfully destroyed the facility.
