Papers relating to the War of 1812, subdivided into four sections:

1) Charles S. Todd papers, 1835-1871. Todd (1791-1871) served as judge advocate and officer with William H. Harrison in the campaigns in 1812-1813 and later was active in the United States diplomatic service. His letters, mainly to Draper, interview notes, and newspaper articles not only give his recollections of Harrison and the northwestern campaigns but also comment on other topics: Kentucky pioneers he had known, including George Rogers Clark, William Stewart, and members of the Shelby family; the writings of historians Benjamin Drake and Benson J. Lossing; his allegiance to the Union during the Civil War and his reactions to the removal of General George B. McClellan (1862) and to the assassination of Lincoln (1865).

2) Benjamin Whiteman papers, 1812-1815, 1854. A small group of letters and orders kept by Whiteman (1769-1852) as general of the Ohio militia in the northwestern campaigns concern troop movements, recruitment problems, and friction between state militia and regular army. Correspondence includes one letter written by Whiteman, and a contemporary copy of a letter by Harrison to Secretary of War John Armstrong about the siege of Fort Meigs (Ohio). Among other correspondents are James Findlay, Othniel Looker, and Thomas Worthington. Provenance of the papers is given in the 1854 letter to Draper by Whiteman's son.

3) Nathan Heald papers, 1811-1835. In 1812 Heald (1775-1832) was captain of a company of the First Regiment of United States Infantry stationed at Fort Dearborn; in attempting to carry out orders for the evacuation of the fort, Heald was wounded and captured, and the other soldiers and settlers were either massacred or taken into captivity. Records, 1811-1813, include: a muster roll, payrolls, and other reports for Heald's company from October 1811, through June 1812; William Hull's letter of July 29, 1812, ordering the evacuation of Fort Dearborn; orders, letters, and receipts concerning Heald's claims for postage, baggage transportation, and treatment by an Indian physician during his captivity; Heald's parole and documents about his exchange signed by United States officials, Thomas H. Cushing and John Mason, and by a British agent, Thomas Barclay; and a bill of sale for a Negro purchased by Heald in Kentucky. Papers of later dates relate to his successful claim for a pension for disability due to his war wound, his move to Missouri in 1817, and legal proof of his death. Additional Heald papers are in volumes 17U and 24U.

4) A group of four accounts relating to the war in the Northwest: Benjamin F.H. Witherell's manuscript on William Hull and the battle of Monguagon [Brownstown]; James Dalliba's printed pamphlet, A Narrative of the Battle of Brownstown (New York, 1816); a manuscript copy of the publication by Josiah Snelling entitled Remarks on General William Hull's Memoirs of the Campaign of the Northwestern Army, 1812 (Detroit, 1825); and extracts about Tecumseh copied by Draper from James Foster's History of Hull's Expedition (Chillicothe, 1812).
