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.
List of memorials and monuments at Arlington National Cemetery
A number of public improvements and memorials were planned for construction in the Washington, D.C., metropolitan area for the 1932 bicentennial of the birth of George Washington, the first President of the United States and American Revolutionary War hero. Among these were Arlington Memorial Bridge and the Mount Vernon Memorial Parkway (now known as the George Washington Memorial Parkway). To link the Virginia landing of the bridge with Arlington National Cemetery, a wide avenue known as Memorial Avenue was constructed and a new entrance to the cemetery (the Hemicycle) constructed.
