I am an official National Park Service Photographer. A big part of my job is to capture moments of people appreciating our national parks. I am the photographer and the NPS owns the copyright to this picture. It has been made public domain and thus I have the right to give you permission to use it. This image captures a Union regiment marching to the sunken road during the sesquicentennial of the Battle of Antietam.
On September 17,1862, more than 23,000 soldiers were killed, wounded, or missing in the battle at Antietam, a pivotal battle in the Civil War. Visitors can take a self-guided 8.5 mile tour of the battlefield by car, bicycle or on foot. The park includes the Antietam National Cemetery, which honors 5,000 Union soldiers who died in the battle.
