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
George Washington Parke Custis, grandson of Martha Washington and adopted son of George Washington, acquired the land that now is Arlington National Cemetery in 1802, and began construction of Arlington House, which was ultimately named after the village of Arlington, Gloucestershire, England, where his family was originally from. The estate passed to Custis' daughter, Mary Anna, who had married United States Army officer Robert E. Lee. Custis' will gave a "life inheritance" to Mary Lee, allowing her to live at and run Arlington Estate for the rest of her life but not enabling her to sell any portion of it. Upon her death, the Arlington estate passed to her eldest son, George Washington Custis Lee.
