Oct. 31st.—We have got an invitation from the Regent for to-night and are going. I learn from Sir Philip Francis, who dined there yesterday, the Prince was very gay. . . . There were twenty at dinner—no politicks—but still Francis says he thinks, from the language of the equerries and understrappers, that the campaign in Portugal and Lord Wellington begin to be out of fashion with the Regent. I think so too, from a conversation I had with one of the Gyps to-day—Congreve, author of the rocketts, and who is going, they say, to have a Rockett Corps.* He affects to sneer rather at Wellington’s military talents. The said Congreve was at the same school with me at Hackney, and afterwards at Cambridge with me; after that, a brother lawyer with me at Gray’s Inn. Then he became an editor of a newspaper . . . written in favour of Lord Sidmouth’s administration, till he had a libel in his paper against Admiral Berkeley, for which he was prosecuted and fined £1000. Then he took to inventing rocketts for the more effectual destruction of mankind, for which he became patronised by the Prince of Wales, and here he is—a perfect Field Marshall in appearance. About 12 years ago he wrote to me to enquire the character of a mistress who had lived with me some time before, which said mistress he took upon my recommendation, and she lives with him now, and was, when I knew her, cleverer than all the equerries and their Master put together.
