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.
Dayton National Cemetery
The cemetery was established in 1867 as a place to inter veterans who died while under the care of the Central Branch of the National Asylum for Disabled Volunteer Soldiers and Seamen, located in Dayton. The first interment, of Civil War veteran Cornelius Solly, was on September 11, 1867. The National Asylum became part of the newly formed Department of Veterans Affairs in 1930 and evolved into today's Dayton VA Medical Center. The cemetery was administered as part of the medical center until 1973, when it was transferred to the National Cemetery Administration.
