About this video

Japan believed their secret naval code “JN-25” was unbreakable. But deep inside a quiet U.S. base, American codebreakers cracked it — reading every Japanese message before the ships even sailed.

When Japan launched its attack on Midway, U.S. forces were already waiting. In broad daylight, they struck first, destroying four Japanese carriers and shifting the balance of the Pacific War forever.

A silent victory — won by intelligence, not firepower.
