Japanese Never Knew U.S. Navy Codebreakers Cracked Their JN-25 Naval Code by Midway

Discover the untold story of how U.S. Navy codebreakers in a Pearl Harbor basement cracked Japan's "unbreakable" JN-25 naval code before the Battle of Midway in 1942, changing the course of World War II in the Pacific. This comprehensive historical account reveals how Commander Joseph Rochefort and his team at Station HYPO used IBM machines and brilliant cryptanalysis to read Japanese military communications throughout the war, while the Imperial Japanese Navy never suspected their most secure code had been compromised. Learn about the famous "AF water shortage" deception that confirmed Midway as the target, the assassination of Admiral Yamamoto based on decoded messages, and the catastrophic intelligence failure that cost Japan the war. Based on declassified documents and featuring firsthand accounts from the codebreakers themselves, this meticulously researched narrative explores one of history's most consequential intelligence triumphs and shows how a small group of American cryptanalysts defeated the Japanese Navy through mathematics and determination, saving countless American lives while remaining unsung heroes for decades.
