Memorial

This was perhaps as poignant a memorial at the Antietam battlefield as any of the more carefully sculpted monuments and pillars.

Not really related: the battlefield preservation people have a tough job finding the balance between enough information about who stood where when to make the reenactors and Civil War buffs happy, but also provide simple enough context for normal people to understand why a given site was significant without having to wade through walls of text. I think the Antietam people (and the Gettysburg people) do a pretty good job of it.
