Constant closes his memoirs with why he didn’t follow Napoleon to his exile.
These were our first generally not credible memoirs but that’s how this guy, his ghostwriter and his publisher released this book. Anything said only in this book is suspect particularly if it paints the Emperor in a negative light. That’s how disinformation works. They slip the poison in between the truth.
