Famed for his masterful oratory and fearless criticism of parliamentary opponents, William Pitt the Elder (1708-78) distinguished himself through the strong leadership he provided during Britain's struggle against France in the Seven Years' War. Edited by his great-grandsons and first published between 1838 and 1840, this four-volume collection presents nearly forty years' worth of letters to and from the great statesman. Each volume also contains a useful list of the principal officers of state for the period covered, along with facsimile plates of letters and signatures by some of Pitt's eminent correspondents. Volume 3 (1839) covers the period from 1766 through to November 1770. Following Rockingham's resignation in July 1766, Pitt accepted a peerage and became the Earl of Chatham, forming a new ministry that lasted until 1768. As prime minister, he was constantly troubled by longstanding health problems.
