The Prince at first received him with suspicion, then he tolerated him coldly, and it was not until Marmont fascinated him with stories of the genius and unparalleled greatness of his father's history that the young man subdued his prejudices and encouraged the Marshal in his visits to his apartments, in order that he might learn all that Marmont could tell him of his father's qualities and accomplishments. The young Napoleon caused the General to marvel at the quick intelligence he displayed in the pointed comments made on his father's career. In recognition of his services Marmont was presented with a portrait of the Prince.[20] His cousin, Prince Napoleon, son of King Jerome, in his book "Napoleon and His Detractors," obviously desires to convey the impression that all questions, important or unimportant, relating to the Emperor, were studiously kept from his son, and until he arrived at a certain age there can be little doubt that undue and unnatural precautions were taken to prevent the Emperor's name being spoken, but the means used for this purpose must have proved abortive, as everything points to him having been well informed. He appears to have had an instinctive knowledge that nullified the precautions of the Court of Vienna, and especially its culpable Chancellor, Metternich, whose clumsy and heartless treatment is so apparent to all students of history. Probably this is the policy that prevailed up to 1830 which Prince Napoleon complains of. Be that as it may, we are persuaded that the Duke was not only well informed, but took a keen interest in the events of his own and of his father's life, long before the advent of Marmont as his tutor. For instance, on one occasion his friend, Count Prokesch, dined with his grandfather in 1830, and at table the Prince was afforded great pleasure in having the opportunity of conversing with this distinguished man. The young Duke knew that Prokesch had broken a lance in 1818 in defence of his father, and he eagerly availed himself of the chance of saying some very complimentary things to the Count. He informs him that he has "known him a long while, and loved him because he defended his father's honour at a time when all the world vied with each other to slander his name"; and then he continues: "I have read your 'Battle of Waterloo,' and in order to impress every line of it on my memory I translated it twice in French and Italian."[21] Obviously this young man was neither a dunce nor indolent when his father's fame and his own interests were in question.
