A survey is planned next month at the site where the Battle of Moore's Mill occurred in July 1862 in Callaway County, near what is now known as Calwood.
The Fulton Sun reports that the excavation is being funded by a grant from the American Battlefield Protection Program of the National Park Service.
The survey will be supervised by employees of Lindenwood University in St. Charles and the University of Nebraska-Lincoln. Faculty and students from Westminster College in Fulton also plan to participate.
