Walpoles' policy. The assault on the government prompted by Bolingbroke was continued in the House of Commons by Windham, and great efforts were made to establish the alliance between the Tories and the Opposition Whigs. The Excise Bill in 1733 and the Septennial Bill in the following year offered opportunities for further attacks on the government, which Bolingbroke supported by a new series of papers in the _Craftsman_ styled "A Dissertation on Parties"; but the whole movement collapsed after the new elections, which returned Walpole to power in 1735 with a large majority. Bolingbroke retired baffled and disappointed from the fray to France in June, residing principally at the chateau of Argeville near Fontainebleau. He now wrote his _Letters on the Study of History_ (printed privately before his death and published in 1752), and the _True Use of Retirement_. In 1738 he visited England, became one of the leading friends and advisers of Frederick, prince of Wales, who now headed the opposition, and wrote for the occasion _The Patriot King_, which together with a previous essay, _The Spirit of Patriotism_, and _The State of Parties at the Accession of George I._, were entrusted to Pope and not published. Having failed, however, to obtain any share in politics, he returned to France in 1739, and subsequently sold Dawley. In 1742 and 1743 he again visited England and quarrelled with Warburton. In 1744 he settled finally at Battersea with his friend Hugh Hume, 3rd earl of Marchmont, and was present at Pope's death in May. The discovery that the poet had printed secretly 1500 copies of _The Patriot King_ caused him to publish a correct version in 1749, and stirred up a further altercation with Warburton, who defended his friend against Bolingbroke's bitter aspersions, the latter, whose conduct was generally reprehended, publishing a _Familiar Epistle to the most Impudent Man Living_. In 1744 he had been very busy assisting in the negotiations for the establishment of the new "broad bottom" administration, and showed no sympathy for the Jacobite expedition in 1745. He recommended the tutor for Prince George, afterwards George III. About 1749 he wrote the _Present State of the Nation_, an unfinished pamphlet. Lord Chesterfield records the last words heard from him: "God who placed me here will do what He pleases with me hereafter and He knows best what to do." He died on the 12th of December 1751, his wife having predeceased him in 1750. They were both buried in the parish church at Battersea, where a monument with medallions and inscriptions composed by Bolingbroke was erected to their memory.
