Like many Civil War battlefields near Washington, the site of the bloodiest single-day clash in U.S. history is a well-preserved park visited each year by thousands who walk the rolling fields and seek insight into a turbulent period of America's past. More than 20,000 soldiers were killed or wounded in the Sept. 17, 1862, battle. To match feature USA-LANDMARKS/BATTLEFIELDS REUTERS/David Alexander/Files (UNITED STATES)
