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.
The Arts of War and The Arts of Peace
Congress finally authorized construction of the Arlington Memorial Bridge in 1925. Major traffic jams clogged the narrow and decrepit Highway Bridge during the November 1921 dedication of the Tomb of the Unknown Soldier at Arlington National Cemetery, angering members of Congress and President Warren G. Harding. Recognizing the need for a new bridge, Congress enacted legislation in June 1922 funding at last the work of the Arlington Memorial Bridge Commission. The bridge commission on April 4, 1923, chose the architectural firm of McKim, Mead and White to design the structure. Architect William Mitchell Kendall was the lead designer.
