The history of the negotiations at Ghent has been recounted by Mahan and Henry Adams, and more recently by F. A. Updyke, "The Diplomacy of the War of 1812" (1915). Aside from the "State Papers," the chief sources of information are Adams's "Life of Gallatin" and "Writings of Gallatin" the "Memoirs of John Quincy Adams," 12 vols. (1874-1877), and "Writings of John Quincy Adams" 7 vols. (1913-), edited by W. C. Ford, the "Papers of James A. Bayard, 1796-1815" (1915), edited by Elizabeth Donnan, the "Correspondence, Despatches, and Other Papers, of Viscount Castlereagh," 12 vols. (1851-53), and the "Supplementary Despatches of the Duke of Wellington," 15 vols. (1858-78). The Proceedings of the Massachusetts Historical Society, vol. XLVIII (1915), contain the instructions of the British commissioners. "A Great Peace Maker, the Diary of James Gallatin, Secretary to Albert Gallatin" (1914) records many interesting boyish impressions of the commissioners and their labors at Ghent.
