The city has set aside a small sliver of land at the base of State Street hill, at Lafayette St to remember those men. It's now called Veteran's Park There are monuments there for most of the conflicts the United States has been involved in. Arguably the worst was the Civil War - North against South, brother against brother.
This monument remembers a different Civil War battle on each face. I chose Gettysburg because of Lincoln's speech commemorating the Gettysburg cemetery.
