PARIS (AFP) ― A rare letter in English written by Napoleon Bonaparte ― and replete with errors ― fetched 325,000 euros ($406,445) at an auction Sunday in Paris.

The one-page letter, dated March 9, 1816, penned by Napoleon during his post-Waterloo exile on the South Atlantic island of Saint Helena, was one of just three known in the world, said auction house Osenat.

Addressed to the Count of Las Cases, Napoleon’s companion in exile, the letter was acquired by the private Museum of Letters and Manuscripts in Paris and originally estimated to fetch just 60,000 to 80,000 euros.
