The most painstaking account of Burr's expedition is W. F. McCaleb's "The Aaron Burr Conspiracy" (1903) which differs from Henry Adams's version in making James Wilkinson rather than Burr the heavy villain in the plot. Wilkinson's own account of the affair, which is thoroughly untrustworthy, is contained in his "Memoirs of My Own Times," 3 vols. (1816). The treasonable intrigues of Wilkinson are proved beyond doubt by the investigations of W. R. Shepherd, "Wilkinson and the Beginnings of the Spanish Conspiracy," in vol. IX of "The American Historical Review," and of I. J. Cox, "General Wilkinson and His Later Intrigues with the Spaniards," in vol. XIX of "The American Historical Review." James Parton's "Life and Times of Aaron Burr" (1858) is a biography of surpassing interest but must be corrected at many points by the works already cited. William Coleman's "Collection of the Facts and the Documents relative to the Death of Major-General Alexander Hamilton" (1804) contains the details of the great tragedy. The Federalist intrigues with Burr are traced by Henry Adams and more recently by S. E. Morison in the "Life and Letters of Harrison Gray Otis," 2 vols. (1913). W. H. Safford's "Blennerhassett Papers" (1861) and David Robertson's "Reports of the Trials of Colonel Aaron Burr for Treason, and for a Misdemeanor," 2 vols. (1808), brought to light many interesting facts relating to the alleged conspiracy. The "Official Letter Books of W. C. C. Claiborne, 1801-1816," 6 vols. (1917), contain material of great value.
