A few images from the Gettysburg National Battlefield Park, in Gettysburg, Pennsylvania. At just short of 4,000 acres, the extensive grounds contain dozens of memorials, large and small, as well as the Gettysburg National Cemetery, where most of the battle dead are buried.
The park preserves and memorializes the costliest battle in U.S. history. Over three days in 1863 (July 1 through 3), 165,00 soldiers in the Union and Confederate armies fought a series of battles around the Pennsylvania town of Gettysburg, resulting in between 46,000 and 51,000 killed, wounded, and missing.
