Kampen om tungtvannet

"Kampen om tungtvannet"("The Battle for the heavy-water") is a movie about how Norwegian saboteurs destroyed the factory at Rjukan, which produced heavy-water, which again was vital for making a German atomic-bomb. Some of the guys playing the Norwegian saboteurs are the real men, who risked their lives by blowing up the factory at Rjukan. The acting isn`t the best, but remember that the movie is from 1948, and the fact that this is no American blockbuster. If you can forgive it for having these flaws, you should be able to enjoy it. 7/10

I saw this film originally in Norway (in Norwegian) in 1965 and was very impressed even then, particularly as several of the "actors" had taken part in the raid which made the film entirely credible. However, it is now possible to buy a version with English dialogue from the resistance and special forces museum in the Akershus fortress in Oslo. Ray Mears has also produced an excellent documentary for the BBC in which he attempted to re-create what happened. Several of the team were interviewed in that documentary. Inspired by the film we have visited Vermork the heavy water factory near Rjukan and were amazed at the skill and bravery of the men who took part in the raid, all of whom evaded the Germans and survived the war. The film made later in Hollywood starring Kirk Douglas does not reflect the reality in the same way.

by saying that,I mean that this is not a well made movie but it's a very good version of the real event and the best depiction so far.and if you are a WW2 buff then this is a treat for you,cause there are three out of four saboteur members playing roles in this movie. It's theater acting at best but then this is still as said before a semi documentary.

Me personally am a die hard fan of our nearly over-human heroes of the second world war,and there should be hundreds of these movies showing us what they did so it won't get forgotten by next generations.Cause nowadays kids doesn't read books,they watch movies.

So if you want a action extravaganza,rent Private Ryan,this is the truth about lingering pain,outrageous endurance and the will to fight when all seems lost.

"In April 1946, the University of Chicago agreed to operate Argonne National Laboratory, with an association of Midwestern universities offering to sponsor the research. Argonne thereby became the first "national" laboratory. It did not, however, remain at its original location in the Argonne forest. In 1947, it moved farther west from the "Windy City" to a new site on Illinois farmland. When Alvin Weinberg visited Argonne's director, Walter Zinn, in 1947, he asked him what kind of reactor was to be built at the new site. When Zinn described a heavy-water reactor operating at one-tenth the power of the Materials Testing Reactor under design at Oak Ridge, Weinberg joked it would be simpler if Zinn took the Oak Ridge design and operated the Materials Testing Reactor at one-tenth capacity. The joke proved unintentionally prophetic."

The S-50 plant used convection to separate the isotopes in thousands of tall columns. It was built next to the K-25 power plant, which provided the necessary steam. Much less efficient than K-25, the S-50 plant was torn down after the war.

Concerned that the Atomic Energy Commission research program might become too academic, Lilienthal established a committee of industrial advisers, and during a November visit to Oak Ridge, he discussed with Clark Center, manager of Carbide & Carbon, a subsidiary of Union Carbide Corporation at Oak Ridge, the possibility of the company assuming management of the Laboratory.

Prince Henry (of Prussia) Arriving in Washington and Visiting the German Embassy (1902). Evidently, with Prince Henry of Prussia according to the principles of science and its dangers their were already concerns with the applications of new science with military applications. The Hohenzollern (1902/II), "Kaiser Wilhelm's splendid yacht at the 34th St. Pier, New York. Taken at the exact moment of Prince Henry's arrival, and the raising of the royal standard." If Royalty knew of these necessary precautions to citizen welfare then what was the necessity of the warfare WWI and WWII. The quality of management control I presume?

Thus, did the commandos of Operation Swallow volunteer for a military mission, or a business plan, based on the security principles of Laboratory management? Because supposedly their were no survivors, and the ones who were caught in Europe ordered to be executed. Of the 400 man commando team the survivors who were captured were executed under orders of the German Army against subversion, and espionage acts of the State of Germany.

I've received this movie from a cousin in Norway and had to convert it from Norwegian to American format with a copied video. Comparing this film (1948) with the Heroes of Telemark (1965), Kampen om Tungtvannet (The Struggle for the Heavy Water) casts the saboteurs themselves, playing their respective roles, though actors were also cast to play the roles of the saboteurs who have given their lives in Norway's struggle for freedom in later campaigns. The plot is in four languages: Norwegian along with French, German and English (complete with Norwegian subtitles).

Impressive during this course of history was what led to the struggle. French scientists were interested in obtaining some two hundred kilograms of heavy water from Norsk Hydro in Vemork to take back to France in order to do lab studies on its effectiveness. Simultaneously, the Nazis, too, were interested in obtaining heavy water to build a secret weapon. The French were worried that the Nazis might take an early lead by invading Norway, and through secret codes, their man carefully eluded Nazi spies on his trip to Oslo where he received the heavy water and making it back without hindrance. He was watched by two spies as he boarded an airliner, but they did not see him hop out on the other side where he crossed the tarmac to another plane nearby where his cargo was waiting for him. This clever trick worked by using the airliner as a decoy that the Nazis later forced down in Hamburg.

However, the invasion of Norway on the morning of April 9, 1940, the Nazis took over Norsk Hydro and it was up to the Norwegian Underground and British intelligence in London to take action. Professor Leif Trondstad volunteered the services of eleven young Norwegians; the "Swallow" and "Gunnerside" groups who would successfully sabotage the heavy water production in Vemork. This was shown in detail on how they actually carried out the operation, including the sinking of the ferryboat after the Nazis abandoned Norsk Hydro to take the shipment of heavy water on rail cars to Berlin.

The quality of the film was fair though there were many splices in the film. I highly recommend this film to anyone interested in World War II history.
