AI Unlocks Mystery of Napoleon’s Coded Letter After 217 Years

An engineer at a cybersecurity company has used artificial intelligence to decipher a mysterious letter written by French military leader Napoleon Bonaparte 217 years ago.

The breakthrough centres on an encrypted message whose meaning had remained elusive for more than two centuries.

AI helped the engineer unlock the letter’s code, bringing modern computational tools to a puzzle rooted in Napoleon’s era.

The available account does not identify the engineer or the company, nor does it explain which AI system was used or how the deciphering process worked.

The contents of the decoded message have also not been provided, leaving its historical significance unclear.
