AI Deciphers Napoleonic Military Message After 217 Years

A coded military message from Napoleon’s era has been deciphered with the help of artificial intelligence after remaining unread for about 217 years.

Working from a single image, the AI-assisted effort took just six hours to interpret the message, revealing what the emperor communicated to his troops before a war with Austria.

The breakthrough brings a previously inaccessible piece of military correspondence back into view, offering a glimpse of communication within Napoleon’s forces ahead of the conflict.

The account does not specify the message’s wording, the encryption method used or how the decoded text was verified. Those details would be needed to assess both its historical significance and the reliability of the interpretation.

Even with those questions unanswered, the reported result points to AI’s potential as a tool for examining historical documents whose contents have long been obscured by codes.
