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.
Montgomery C. Meigs
A staunch Unionist, Meigs detested the Confederacy. His feelings led directly to the establishment of Arlington National Cemetery. On July 16, 1862, Congress passed legislation authorizing the U.S. federal government to purchase land for national cemeteries for military dead, and put the U.S. Army Quartermaster General in charge of this program. The Soldiers' Home in Washington, D.C., and the Alexandria Cemetery were the primary burying grounds for war dead in the D.C. area, but by late 1863 both cemeteries were full. In May 1864, Union forces suffered large numbers of dead in the Battle of the Wilderness. Meigs ordered that an examination of eligible sites be made for the establishment for a large new national military cemetery. Within weeks, his staff reported that Arlington Estate was the most suitable property in the area. The property was high and free from floods (which might unearth graves), it had a view of the District of Columbia, and it was aesthetically pleasing. It was also the home of Robert E. Lee, future General-in-Chief of the Confederacy, and denying Lee use of his home after the war was a valuable political consideration. Although the first military burial at Arlington had been made on May 13, Meigs did not authorize establishment of burials until June 15, 1864. Meigs ordered that the estate be surveyed and that be set aside for use as a cemetery.
