Germans Never Knew Allied Codebreakers Had Cracked Enigma

Discover the greatest intelligence failure of World War II in this shocking historical documentary about how Nazi Germany never knew the Allies had cracked their "unbreakable" Enigma code. For 30 years after WWII ended, German military leaders including Admiral Karl Dönitz believed they lost due to Allied radar and superior resources, until the devastating truth was revealed in 1974 - British codebreakers at Bletchley Park had been reading every secret German military communication since 1940. This meticulously researched documentary reveals how 783 U-boats were destroyed, 30,000 submariners died, and countless military operations failed because the Germans' absolute faith in Enigma's mathematical security blinded them to mounting evidence of compromise. Through declassified documents, survivor testimonies, and expert analysis, learn how Polish mathematicians first broke Enigma in 1932, how Alan Turing's Bombe machines industrialized codebreaking, and why multiple German investigations failed to uncover the truth despite explicit warnings from Swiss intelligence. Featuring the dramatic 1978 confrontation between former enemies, Dönitz's emotional reaction to learning the truth, and the extraordinary 30-year silence of 10,000 Bletchley Park workers, this documentary exposes how institutional blindness and misplaced certainty led to one of history's most consequential intelligence failures, potentially shortening WWII by 2-4 years and saving millions of lives.
