Peel made up his mind to the fact that Catholic Emancipation must, as soon as possible, become the work of Parliament. But he did not yet believe that he was the right man to undertake the task. It seemed to him that one who had always been regarded as the determined opponent of Emancipation would not be likely to win over many supporters among his Tory friends for such a sudden change of policy. He did not think himself well suited, and he was not inclined, to conduct the negotiations which would be necessary between any Government attempting such a task and the Irish advocates of Emancipation. His idea was that Lord Grey, as the head of the reforming party, would be the statesman best qualified to undertake such an enterprise and most likely to carry it to an early success. His first business, however, would clearly be to convince the Duke of Wellington that Catholic Emancipation was inevitable, and this work he at once set himself to accomplish. He had some trouble in bringing the Duke over to his own opinions, but the Duke became convinced in the end, and, indeed, both at that time and after, the Duke was always inclined to follow Peel's guidance, on the plain, practical, soldierly principle that Peel understood political affairs much better than he did, {76} and that Peel's advice was always sure to be sound and safe. So the Duke, too, became convinced that Catholic Emancipation must be accepted as inevitable, and that the sooner it was carried through the better. But Wellington was strongly opposed to the idea of handing over the work to Lord Grey. He showed that it would be hardly possible to induce King George to accept the services of Lord Grey for such a purpose. The King was known to dislike Lord Grey, whose stern, unbending manners could not be welcome to a sovereign unaccustomed to the dictation of so uncourtierlike an adviser as the leader of the Whig party.
