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.
Baltimore National Cemetery
The area of the Baltimore National Cemetery was once part of an elevated site in Baltimore, referred to as early as 1750 as the Cloud Capped estate. It was originally owned by the Baltimore Company and Charles Carroll of Carrollton. In 1890 it was acquired by Blanchard and Susan Randall. When the nearby Loudon Park National Cemetery was deemed full, the War Department surveyed the area for a new site. In 1936 the federal government took possession of the land for a cost of $95,000, and began converting the estate to "Little Arlington". The old mansion was demolished, fences were put up, roads were constructed, and landscaping was done as part of a Works Progress Administration to invest in infrastructure during the Great Depression.The first interment took place on December 22, 1936, but the cemetery was not formally dedicated until May 30, 1941.
