The Telemark Raids: How Norway Prevented Germany from Developing an Atomic Bomb
TLDR During World War II, Norwegian commandos carried out the Telemark raids to destroy Germany's heavy water production facility in Norway, effectively crippling their ability to develop an atomic bomb. The raids were successful in preventing Nazi Germany from achieving nuclear fission and remain a celebrated Norwegian military operation.
Timestamped Summary
00:00
The Allies were concerned about the development of a German atomic bomb during World War II, leading to the telemark raids in Norway to destroy anything related to the Nazi atomic program.
02:33
The Telemark region of Norway was the only place in the world creating heavy water before World War II, which is a crucial component for producing plutonium and was pursued as an alternative to the difficult process of separating uranium isotopes for atomic bomb development.
04:27
Before the German invasion of Norway in 1940, the director of the Vamork facility agreed to lend France the entire supply of heavy water in the world at the time, in response to German companies offering to buy their entire production, which deeply concerned the Allies who knew the potential use of heavy water for atomic bomb development, leading them to plan a covert mission to destroy the facility from the inside.
06:25
A four-man team of Norwegian commandos, trained in the UK, were parachuted into Norway and made contact with the British to begin the next phase of Operation Grouse, finding the Vamork facility to be less heavily guarded than expected, leading the British to initiate Operation Freshman, which unfortunately resulted in crashes and the capture and execution of the surviving British commandos.
08:11
The Norwegian commandos successfully infiltrated the Vamork facility, planted bombs on the electrolysis tanks, and destroyed the entire supply of heavy water, crippling the German ability to produce it temporarily.
09:58
The bombing missions over the Vamork facility were not entirely successful, but eventually the sinking of a ferry carrying heavy water effectively ended Germany's heavy water program.
11:54
The Telemark raids, specifically Operation Gunnerside, were successful in preventing Nazi Germany from developing a nuclear fission reactor, and it remains the most celebrated Norwegian military operation of World War II.
