The Keokuk National Cemetery is the final resting place for more than 600 Union and Confederate soldiers.
Most of the soldiers were from Iowa, Illinois, and Missouri.
A total of 17 states are represented in the cemetery, though, including Ohio, Alabama, and Texas.
A special ceremony was held to bring those soldiers "home."
Soil was collected from all 17 states. It was spread on the graves so soldiers could be buried under their native soil.
