United States v. Lee (1882)
With local cemeteries in Alexandria County and Alexandria filling rapidly with war dead, Quartermaster General of the United States Army Montgomery C. Meigs proposed using of the Arlington estate as a cemetery. The first burial there was made on May 13, 1864. United States Secretary of War Edwin M. Stanton approved the establishment of a military cemetery on June 15, 1864, creating Arlington National Cemetery. By the end of the war in April 1865, more than 16,000 people had been buried at Arlington. In September 1866, a memorial and a burial vault (containing the remains of 2,111 U.S. and Confederate soldiers who died at the First Battle of Bull Run, Second Battle of Bull Run, and along the Rappahannock River) were buried in Lee's former wildflower garden on the mansion's east side beneath the Civil War Unknowns Monument, a memorial to honor unknown soldiers who had died during the American Civil War.
Arlington Memorial Amphitheater
Memorial Amphitheater is an outdoor amphitheater, exhibit hall, and nonsectarian chapel located in Arlington National Cemetery in Arlington County, Virginia, in the United States. Designed in 1913 as a replacement for the older, wooden amphitheater near Arlington House, ground was broken for its construction in March 1915 and it was dedicated in May 1920. In the center of its eastern steps is the Tomb of the Unknowns, dedicated in 1921. It has served as the site for numerous Veterans Day and Memorial Day services, as well as for memorial services and funerals for many individuals.
