Arlington House, The Robert E. Lee Memorial
By early 1864, the military cemeteries of Washington, D.C., and Alexandria, Virginia, were rapidly filling with war dead. Quartermaster General of the United States Army Montgomery C. Meigs proposed using of the Arlington estate as a cemetery. United States Secretary of War Edwin M. Stanton approved the establishment of a military cemetery on June 15, 1864, creating Arlington National Cemetery. Meigs believed that since Lee had committed treason in deciding to fight against the Union, denying Lee use of the mansion after the war was a rough form of justice. Meigs decided that a large number of burials should occur close to Arlington House to render it unlivable. Officers were to be buried next to the main flower garden south of the house, and the first burial occurred here on May 17. Meigs ordered that additional burials commence immediately on the grounds of Arlington House in mid-June. When Union officers bivouacked in the mansion complained and had the burials temporarily stopped, Meigs countermanded their orders and had another 44 dead officers buried along the southern and eastern sides of the main flower garden within a month.
Arlington National Cemetery
Before the Arlington Memorial Amphitheater was completed in 1921, important ceremonies were held at what is now known as the "Old Amphitheater." This structure sits where Robert E. Lee once had his gardens. The amphitheater was built in 1868 under the direction of Civil War General John A. Logan. Gen. James A. Garfield was the featured speaker at the Decoration Day dedication ceremony, May 30, 1868, later being elected as President of the United States in 1881. The amphitheater has an encircling colonnade with a latticed roof that once supported a web of vines. The amphitheater has a marble dais, known as "the rostrum", which is inscribed with the U.S. national motto found on the Great Seal of the United States, "E pluribus unum" ("Out of many, one"). The rostrum was designed by General Montgomery C. Meigs, then Quartermaster General of the U.S. Army. The amphitheater seats 1,500 people and has hosted speakers such as William Jennings Bryan.
