When I first resolved to write this History, I applied verbally to the duke of Wellington to give me papers in aid of my undertaking. His answer in substance was, that he had arranged all his own papers with a view to publication himself—that he had not decided in what form they should be given to the world, or when, probably not during his lifetime, but he thought his plan would be to “_write a plain didactic history_” to be published after his death—that he was resolved never to publish anything unless he could tell the whole truth, but at that time he could not tell the whole truth without wounding the feelings of many worthy men, without doing mischief: adding in a laughing way “_I should do as much mischief as Buonaparte_.” Then expatiating upon the subject he related to me many anecdotes illustrative of this observation, shewing errors committed by generals and others acting with him, or under him, especially at Waterloo; errors so materially affecting his operations that he could not do justice to himself if he suppressed them, and yet by giving them publicity he would ungraciously affect the fame of many worthy men whose only fault was dulness. For these reasons he would not, he said, give me his own private papers, but he gave me the documents I have already noticed, and told me he would then, and always, answer any questions as to facts which I might in the course of my work think necessary to put. And he has fulfilled that promise rigidly, for I did then put many questions to him verbally and took notes of his answers, and many of the facts in my History which have been most cavilled at and denied by my critics have been related by me solely upon his authority. Moreover I have since at various times sent to the duke a number of questions in writing, and always they have been fully and carefully answered without delay, though often put when his mind must have been harassed and his attention deeply occupied by momentous affairs.
