Description

---

On May 19, 1945, eleven days after the surrender of Nazi Germany in Europe, a U-boat was escorted into Portsmouth Naval Yard, New Hampshire. News reporters covering the surrender of U-234 were ordered, contrary to all previous and later U-boat surrender procedures, to keep their distance from crew members and passengers of U-234, on threat of being shot by the attending Marine guards. Why the tight security? Buried in the nose of the specially-built mammoth boat, sealed in cylinders “lined with gold,” was 1,120 pounds of enriched uranium labeled “U235”the fissile material from which atom bombs are made. Critical Mass documents how these Nazi bomb components were then used by the Manhattan Project to complete both the uranium bomb dropped on Hiroshima and the plutonium bomb dropped on Nagasaki, to defeat the Japanese and win World War Two and global domination in the modern age.

“Compelling . . . as gripping as good fiction. Hydrick's book is important history well written." —Tony Hillerman, New York Times Best Selling author, Retired Journalism Professor, Decorated Hero of D-Day and the Italian Front

“This is a fascinating book . . . with excellent primary source research." —Joe Sills, Former United Nations spokesperson

“The assertion in Critical Mass that the uranium surrendered to U.S. authorities onboard the German submarine U-234 was enriched U-235 [enriched uranium] is certainly a credible conclusion in view of the storage, containment and prevailing shipping conditions." —Dr. Gary Sandquist, Instructor, Nuclear Engineering, United States Military Academy, West Point

"Critical Mass brings to the surface defining new information, long hidden within archives, about the birth of the Atomic Bomb . . . . Should be in every library." —D. Ray Smith Oak Ridge Y-12 (uranium enrichment facility) Historian

"Important new information about the race for the atomic bomb . . . . Hydrick’s well-written account provides lucid understanding of hitherto unknown and important aspects of the birth of the Nuclear Age." —Dr. Anthony Stranges, Associate Professor, Modern Military Science and Technology, Texas A&M University

"Well-researched, well-reasoned, well-written . . . . Deserves a careful reading and to be taken seriously by both scholars and laymen alike." —Dr. Douglas F. Tobler, Professor Emeritus, Modern German History, Brigham Young University

“A coherent and well researched history of events that have been covered up for half a centuryexciting and revealing!" —Otis Maclay, Pacifica Radio Host

“The best primary source research I have seen in a long, long time." —Gordon Fowkes, Lt. Colonel, US Army (Ret), University of Houston Military History Symposium

“I don’t know much about making buna, synthetic rubber, but I know the electrical consumption that I.G. Farben’s directors described at their buna plant at Auschwitz is very much in line with the huge electrical requirements for developing magnetically enriched uranium . . . . Certainly leads the experienced physicist to believe." —Dr. Delmar Bergen, retired Director, Weapons Program Office, Los Alamos National Laboratory

“I find it difficult to believe the traditional explanation that the Germans spent four fruitless years trying to bring a rubber plant on line, the technology for which they had
previously developed, proven and used. I also cannot comprehend, nor do I believe, a buna (rubber) plant of that time period consumed as much power as the eighth-largest city in the world (Berlinas stated by directors of the plant).” —George M. Ladzun, (Ret.) Director, Process Development, Zeon Chemicals; Manager, Two Synthetic Rubber (buna) Plants, Zeon Chemical
