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.
Confederate Memorial (Arlington National Cemetery)
Confederate military personnel were among those initially buried at Arlington. Some were prisoners of war who died while in custody or who were executed as spies by the Union, but some were battlefield dead. For example, in 1865, General Meigs decided to build a monument to Civil War dead in a grove of trees near the flower garden south of the Robert E. Lee mansion at Arlington. The bodies of 2,111 Union and Confederate dead within a radius of the city of Washington, D.C., were collected. Some of the dead had been interred on the battlefield, but most were full or partial remains discovered unburied where they died in combat. None were identifiable. Although Meigs had not intended to collect the remains of Confederate war dead, the inability to identify remains meant that both Union and Confederate dead were interred below the cenotaph he built. The vault was sealed in September 1866. Other Confederate battlefield dead were also buried at Arlington, and by the end of the war in April 1865 several hundred of the more than 16,000 graves at Arlington contained Confederate dead.
