Mainly notes and correspondence on New York border warfare and Brant's activities during 1777. The majority of the papers, including several poems, pertain to the battle of Oriskany (August 6), in which General Nicholas Herkimer was mortally wounded; many newspaper clippings detail the centennial commemoration in 1877 and the subsequent erection of a memorial monument to Herkimer near the battle site. Other notes and letters relate to a meeting of Brant and Herkimer (June), the battle of Sidney Plains (June), Barry St. Leger's expedition against Fort Stanwix (August), and the capture of the scout John Jenkins (November).

Many names are mentioned in the accounts, but those for whom there is specific biographical or genealogical information include: Ebenezer Cox; John Dusler; Peter J. and William Dyggert (Deichert); John Frey; George, Henry, and Jacob G. Klock; James Mellen (Holliston, Massachusetts, 1753-1834), James Mellen (Hopkinton, Massachusetts, 1739-1812); James Mellen (Hudson, New York, d. 1839); John More and his wife Betsey Taylor; Isaac Paris; and Joseph Wagner. A few notes concern Frederick Follett, who survived wounds and scalping in 1779, and other members of the Follett family.
