Pilgrim Places: Civil War Battlefields, Historic Preservation, and America’s First National Military Parks, 1863-1900, Part IV
Once the national cemeteries were established, they were effectively the only areas of the battlefields in a condition adequate to receive the public in any numbers, and they became the focal points for official ceremonies and other formal acts of remembrance. Most widely observed was Decoration Day, begun at about the end of the war in response to the massive loss of life suffered during the four-year conflict.
