This scarce and extremely detailed battlefield map details the operational area that claimed over 30,000 casualties during the two week long battle. The map locates Anderson's Mill, Crutchfield, Anderson, and Todd's Tavern at the junction of the Brook and Catharpin roads. Drawn on a scale of three inches per mile, the remarkable detail locates roads, houses with occupants named, vegetation, drainage and relief by hachure. The opposing forces are differentiated by red and blue overprinting. The map was prepared by Bvt. Brig. Genl. N. Michler, Major of Engineers by Maj. J.E. Weyss, assisted by F. Theilkuhl, J. Strasser and G. Thompson.
