In “Reviews in Brief: Forthcoming or Recently Published”, the following terse summary of Bascomb’s book appeared.
The story of a small group of British-trained Norwegian commandos who sabotaged Nazi efforts to build an atomic bomb by sabotaging Norsk Hydro, the world’s largest producer of deuterium: heavy water. Discusses advances in physics that led to the race to build the first A-bomb, Britain’s Special Operations Executive (SOE), the Manhattan Project, the privation and brutality of the Nazi occupation of Norway, German scientists’ efforts to build a bomb, and the resolve of the Norwegian resistance.
Of the book, Foreign Affairs had the following to say.
At the heart of this book is the story of the heroic and successful efforts of a small group of Norwegian patriots who sabotaged a German-controlled hydroelectric plant in Vemork, Norway, in February 1943. At the time, the plant was the world’s only source of heavy water, a component of the uranium enrichment process. This was not the first or last attempt to deny Germany access to heavy water. In this authoritative account, Bascomb also describes how a few months before, there had been a calamitous mission undertaken by British commandos, which failed when their gliders crash-landed far from their target; the Germans later executed the surviving soldiers. In November 1943, nine months after the Norwegians’ successful mission, it became apparent that the Germans had started up production again, so the U.S. Army Air Forces bombed the plant. Finally, in 1944, there was a terminal act of sabotage, when two Norwegians sank a ferry carrying the last remaining containers of heavy water to Germany. Germany’s equivalent to the Manhattan Project might well have failed on its own, without these efforts, but it would have been too risky to assume as much. Bascomb offers a vivid and gripping narrative that conveys the heroism and dedication of the anti-Nazi operatives, especially in the face of severe weather conditions, and also delves into the ethics of resistance, which sometimes involves implicating or even killing innocent people.
Bascomb is certainly correct in recognizing the heroes who, believing that the hydroelectric plant was an extraordinary threat, attempted no less than three times to put it out of action permanently. British SOE failed miserably owing to glider crash. Neither attempt by the Norwegians was successful in shutting down the plant. In my view, Bascomb fails miserably on several levels. It demonstrates that journalists who are not trained scientists often get it very wrong.
A number of excellent books have already been written about the heavy-water plant in Vemork and the attempts to destroy it. Incidently, it was heavy water, deuterium oxide (not deuterium) that the plant was producing. Heisenberg’s War is an important read, to see the true role of heavy water. Heavy water is used in certain types of nuclear reactors, where it acts as a neutron moderator to slow down neutrons so that they are more likely to react with the fissile U235 than with U238, which captures neutrons without fissioning. This leads to fissioning U235 but not to a chain reaction. The main value of heavy water would have been to use it in a reactor, hardly an atomic bomb. At one point Heisenberg thought of using a reactor as a kind of dirty radiation bomb, but realized to have a desired effect it would be so large no German plane could transport it.
Skis Against the Atom is another excellent book that tells much more about the Norwegian heroes. It is written, not by a journalist, but by an actual participant in the raids. If you read it, you will likely never be warm again. They faced incredible hardships, an d saw German cruelty result after every raid. There is no question that Bascomb is right when he calls these warriors “heroes.”
Jeffrey T. Richelson’s book Spying on the Bomb traces he evolution of U. S. nculear intelligence efforts—both successes and failures—from the early days of World War II to the twenty-first century.
As a nuclear physicist, it pains me to read over-simplified junk physics and claims of weapons nearly developed that would destroy us all, when these claims are unwarranted.
Should the destruction of the heavy-water production facilities have been carried out? Probably. Were those who risked (and gave) their lives to do the operation heroes? Undoubtedly! If nothing had been done, would Hitler have had nuclear weapons to rain on us? Unreservedly, NO! The mass emigration of physicists from Nazi Germany, and the disdain of those who remained for “Jewish physics” undercut the program so much that it never had a chance for success. That we know in hindsight. Let’s celebrate the heroes without making them saviors of the world.
