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.
Navy Annex
In January 2013, the County Manager of Arlington County, Virginia, and the Executive Director of the Army National Military Cemeteries (consisting of Arlington National Cemetery and the United States Soldiers' and Airmen's Home National Cemetery) signed a Memorandum of Understanding (MOU) between the Arlington County Board and the Department of the Army to expand the Cemetery even further. Under the tentative plan, Arlington County would give up the easement for Southgate Road (which lies between the Navy Annex property and the cemetery's 2012 boundary), and obtain a narrow easement along the southwest border of the Navy Annex site for a new Southgate Road. In exchange, the Department of Defense would give the Navy Annex parking lot to the county.
