message deprecating his ill-will, he wished his arm might rot off if he ever used pen or sword in their service again![9] He now turned to the English government in hopes of pardon. In March 1716 he declared his final abandonment of the Pretender and promised to use his influence to secure the withdrawal of his friends; but he refused to betray any secrets or any individuals. He wrote his _Reflexions upon Exile_, and in 1717 his letter to Sir W. Windham in explanation of his position, generally considered one of his finest compositions, but not published till 1753 after his death. The same year he formed a liaison with Marie Claire Deschamps de Marcilly, widow of the marquis de Villette, whom he married in 1720 after the death in 1718 of Lady Bolingbroke, whom he had treated with cruel neglect. He bought and resided at the estate of La Source near Orleans, studied philosophy, criticized the chronology of the Bible, and was visited amongst others by Voltaire, who expressed unbounded admiration for his learning and politeness. In 1723, through the medium of the king's mistress, the duchess of Kendal, he at last received his pardon, returned to London in June or July, and placed his services at the disposal of Walpole, by whom, however, his offers to procure the accession of several Tories to the administration were received very coldly. During the following winter he made himself useful in France in gaining information for the government. In 1725 an act was passed enabling him to hold real estate but without power of alienating it.[10] But this had been effected in consequence of a peremptory order of the king, against Walpole's wishes, who succeeded in maintaining his exclusion from the House of Lords. He now bought an estate at Dawley, near Uxbridge, where he renewed his intimacy with Pope, Swift and Voltaire, took part in Pope's literary squabbles, and wrote the philosophy for the _Essay on Man_. On the first occasion which offered itself, that of Pulteney's rupture with Walpole in 1726, he endeavoured to organize an opposition in conjunction with the former and Windham; and in 1727 began his celebrated series of letters to the _Craftsman_, attacking the Walpoles, signed an "Occasional Writer." He gained over the duchess of Kendal with a bribe of L11,000 from his wife's estates, and with Walpole's approval obtained an audience with George. His success was imminent, and it was thought his appointment as chief minister was assured. In Walpole's own words, "as St John had the duchess entirely on his side I need not add what must or might in time have been the consequence," and he prepared for his dismissal. But once more Bolingbroke's "fortune turned rotten at the very moment it grew ripe,"[11] and his projects and hopes were ruined by the king's death in June.[12] Further papers from his pen signed "John Trot" appeared in the _Craftsman_ in 1728, and in 1730 followed _Remarks on the History of England by Humphrey Oldcastle_, attacking the
