Copy of Napoleon's last will sold for EUR 357,000

The only known copy of the will of French emperor Napoleon Bonaparte has been sold at an auction in Paris for 357,000 euros, which is more than twice the expected price.

The French buyer said Wednesday he wanted to remain anonymous and planned to keep the will in a private collection.

Druout auction house said the price included taxes and fees.

The will -- dated April 16, 1821 -- offered exceptional insights into Napoleon's final moments before his death 19 days later.

The ailing 51-year-old wrote he wanted his ashes spread over Paris' Seine River. They were instead transferred to Paris' Invalides monument nearly two decades later.

The original, penned in Napoleon's own illegible hand, is in France's national archives.
