Never read that, but having read Napoleon's biography back in middle school, I know he's too neat a person to be stuck in a boring book. I'm sorry you read that piece, Olly, and I feel your pain
Find a few good biographies. The one I read was most entertaining as it mentioned a lot of Napoleon's oddball personality quirks (for instance, that he couldn't stop moving and was always doodling on the tables at meetings). I loved his quote on surgeons.
