Fall Asleep To | The ENTIRE History of Enigma | Codebreaking Secrets of WW2 | War Documentary
Step into the shadow world of intelligence, secrecy, and the battle of wits that helped decide World War II. This documentary tells the entire story of Enigma — the German cipher machine once thought unbreakable, and the Allied codebreakers who proved otherwise.
From the early days of cryptography to the brilliance of Alan Turing and the team at Bletchley Park, this film uncovers how mathematics, machines, and human determination combined to pierce the Axis war effort. You’ll learn how captured codebooks, daring naval missions, and the birth of modern computing all played vital roles in one of history’s greatest secrets.
Follow the journey through the hidden world of signals intelligence, the race against time, and the legacy of Enigma in shaping the outcome of World War II and the dawn of the digital age.
Perfect for history lovers, war buffs, and anyone fascinated by the art of codebreaking — this is the immersive, relaxing long-form documentary to fall asleep to while discovering the untold secrets of the war.
