アメリカ内務省さんのインスタグラム写真 - (アメリカ内務省Instagram)「Today marks the 157th anniversary of the Battle of Antietam. With over 23,000 combined casualties (over 3,600 dead) suffered by both the Union and Confederate armies, it remains the bloodiest day in American history. It’s hard to imagine the horror that ravaged this #Maryland community when you walk the now peaceful fields of #Antietam National Battlefield. Our public lands are managed for their natural and cultural importance. Among them are dozens of battlefields like Antietam. More than a century and a half after the guns fell silent, battlefields preserved for their historical impact now serve as critical natural landscapes, habitat for wildlife and remarkable outdoor classrooms.
