Edited sentence: Banastre Tarleton, later a baronet, was never a lord, as titled in the film.Besides, he was the younger son of a baron, so his title was, "The Hon Charles Fox" not — as in the film — "Lord Charles Fox" and he was only 10 years older than William Pitt, not more than two generations older, as in the film.Charles James Fox died in 1806 (the year before the Abolition bill was passed).The Duke of Clarence was not (and, as a royal duke, could not have been) a member of the House of Commons — as seen in Amazing Grace — but of the House of Lords, where he did speak against the abolition of slavery
