In this Dec. 4, 2010 file photo, luminaries are seen across Antietam National Battlefield in Sharpsburg, Md., to commemorate the soldiers who were killed or wounded during the three-day Civil War battle. The battle was so big, they’re re-enacting it twice. And nearly 8,000 re-enactors had to make a choice: strictly regimented realism or bombastic spectacle? The two privately financed events, both open to the public, were scheduled on back-to-back weekends leading up to Monday’s 150th anniversary of the bloodiest day of combat on U.S. soil.
