Another dishonourable characteristic of the Ministers of Queen Anne at this period was that they were in secret zealous partisans of the Pretender, and whilst openly professing a sacred maintenance of the Protestant succession, were doing all in their power to undermine it. They had given mortal offence to the Elector George of Hanover, the heir to the Throne, by their treachery to the Allies; and, as the health of the queen was most precarious from her excessive corpulence and gout, which was continually menacing a retreat to her stomach, this was equally a cause for their hastening the peace, however disgracefully, and for paving the way, if possible, for the return of the Pretender at the queen's death. Bolingbroke was the great correspondent with St. Germains, as his letters in the Stuart Papers abundantly show. But Oxford, although always more cunning and mysterious, was equally concerned in it; nor was the queen, if we may believe these remarkable papers, by any means averse from the succession of the Pretender, in spite of his stubborn adhesion to Popery. The Jacobite party was numerous, powerful, and indefatigable. They were in the Ministry and in both Houses of Parliament. At this moment a public appointment was made which filled the Whigs with consternation and rage. This was no other than that of the Duke of Hamilton--a supposed partisan of the Pretender--to be Ambassador to the Court of Versailles. Prior was still there, and had all the requisites of a clever and painstaking Envoy; but, being only a commoner and a poet, it did not suit the aristocratic notions of England that he should be accredited Ambassador. Hamilton was appointed, and would thus have had the amplest opportunity of concerting the return of the Stuarts with the base ministers at home. But he was not destined to see Versailles, for, as readers of Thackeray's "Esmond" will remember, he was killed in a duel by Lord Mohun.
