Civil War History in Frederick, MD

Frederick County, Maryland was at the crossroads of the American Civil War. Throughout the conflict, armies marched through the region and several major battles occurred in the Frederick area. In 1862, US and Confederate armies clashed during the Battle of South Mountain, a Union victory that set the stage for the Battle of Antietam.

The United States Army marched through Frederick on its way to victory at Gettysburg in July 1863. A year later, another Confederate invasion came to Frederick, resulting in the Battle of Monocacy on July 9, 1864. In the aftermath of battle, many locations in Frederick County became military hospitals.
