A career officer recalls his rise from junior ranks to becoming first aide-de-camp to Napoleon, tracing campaigns in Egypt and across Europe, battlefield wounds, promotions, and commands. He offers close observations of the emperor's temperament, virtues, and faults, alongside anecdotes about fellow generals, court intrigues, and disciplinary incidents. Chapters describe major actions and strategic movements, personal missions and diplomatic errands, the atmosphere of headquarters, and dramatic episodes such as assassination attempts and sieges. Interwoven are reflections on military duty, loyalty, and the rewards and perils of serving a dominant leader, together with candid accounts of his own successes, injuries, and administrative responsibilities.
