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
Little additional work was done at Memorial Amphitheater until 1954. By then, settling of the amphitheater and entrance hall, cracking of walls and exterior marble, water damage, and other serious problems were beginning to affect the structure. Congress appropriated $15,000 for fiscal 1954 (which began June 30, 1953) for a year-long study of the problems. A preliminary estimate indicated that repairs would cost $179,000. But the finished study identified even more serious issues, almost all of which were caused by design deficiencies which did not take into account the seasonal expansion and contraction of the building's marble. Arlington National Cemetery officials were forced to ask Congress for $447,000 to repair the amphitheater and $179,000 to repair the entrance building. Congress approved the request.
