author
Best known for contributing the appendix to a firsthand Civil War regimental history, this veteran writer helped preserve the story of Minnesota soldiers in a clear, direct way. His surviving work has the feel of lived experience turned into record.

by A. J. (Alfred James) Hill, Charles J. Stees
Charles J. Stees is known today for his contribution to History of Company E of the Sixth Minnesota Regiment of Volunteer Infantry, published in 1899 with A. J. Hill. Sources describe him as Captain Charles J. Stees, and Project Gutenberg notes that the appendix drew from his journal as a former captain in the Sixth Minnesota Volunteer Infantry and earlier a major in Pennsylvania service.
That makes his writing especially valuable: it was not simply compiled from a distance, but rooted in military experience and in the effort to preserve the memory of a specific company and campaign. The book remains the main work clearly associated with his name in major library and public-domain catalogs.
Minnesota Historical Society records also identify a collection of Civil War pension files connected to Pension Agent Charles J. Stees, suggesting that his public work after the war remained closely tied to veterans and their records. I could not confirm enough biographical detail beyond those documented connections, so this overview stays focused on the parts of his life that are well supported.
