Mainly original letters, journals, and other documents kept by participants in Indian wars in the West from 1754 until 1815, with emphasis on events in the Old Northwest in the 1780s and 1790s and in the War of 1812. Related papers include Draper correspondence, materials written by him, and clippings and miscellany. Most of the volumes were arranged by Draper, some during his writing of the unpublished book on “Border Forays” (Series D), others during his preparation of a proposed new edition of Alexander Withers's Chronicles of Border Warfare; the latter, unfinished at the time of Draper's death in 1891, was completed and published by Reuben G. Thwaites in 1895. For this series the Society has an indexed calendar in typescript.
