Additional copies and extracts from archival collections and notes on interviews recorded by Draper in November and December 1860. In Washington, D.C., Draper's sources included: one oral interview (page 52); additional correspondence of George Washington, 1780-1783 (pages 1-77); papers of Thomas Jefferson, 1779-1825 (pages 78-147); and records of the United States House of Representatives, 1811-1838 (pages 148-162). From the nation's capital Draper went to West Chester, Pennsylvania, to examine papers, 1792-1795, of Anthony Wayne (pages 163-210) in possession of Joseph J. Lewis, and to Harrisburg to use Pennsylvania state archives and newspapers files for the 1790s (pages 211-228) before recording interviews (pages 228-304) elsewhere in Pennsylvania, western Virginia, and Ohio. Many of the Washington papers copied relate to the war in New York, and the House of Representatives selections pertain only to the Boone family. Among Wayne's papers are lists and some short statements about prisoners taken in Indian raids in Kentucky from about 1786 through 1794.

A wide variety of references to border events and participants are found in Draper's other documentary selections and interviews; among the many persons mentioned are Samuel Brady, Daniel Brodhead, George Rogers Clark and his brother William, William Cocke, Joseph Crockett, John Filson, the Marquis de Lafayette, J.M.P. Legras, Francis Marion, Joseph Martin, Alexander Mitchell, Edward Perrin and Jacob Van Braam.
