<P> When Virginia seceded from the Union at the start of the American Civil War, Robert E. Lee resigned his commission on April 20, 1861, and took command of the armed forces of the Commonwealth of Virginia, later becoming commander of the Army of Northern Virginia . On May 7, troops of the Virginia militia occupied Arlington and Arlington House . With Confederate forces occupying Arlington's high ground, the capital of the Union was left in an untenable military position . Although unwilling to leave Arlington House, Mary Lee believed her estate would soon be recaptured by federal soldiers . So she buried many of her family treasures on the grounds and left for her sister's estate at Ravensworth in Fairfax County, Virginia, on May 14 . On May 3, General Winfield Scott ordered Brigadier General Irvin McDowell to clear Arlington and the city of Alexandria, Virginia, of all troops not loyal to the United States . McDowell occupied Arlington without opposition on May 24 . </P> <P> At the outbreak of the Civil War, most military personnel who died in battle near Washington, D.C., were buried at the United States Soldiers' Cemetery in Washington, D.C., or Alexandria Cemetery in Alexandria, Virginia, but by late 1863 both were nearly full . 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 . In May 1864, Union forces suffered large numbers of dead in the Battle of the Wilderness . Quartermaster General Montgomery C. 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 the leader of the armed forces of the Confederate States of America, and denying Robert E. Lee use of his home after the war was a valuable political consideration . The first military burial at Arlington, for William Henry Christman, was made on May 13, 1864, close to what is now the northeast gate in Section 27 . However, Meigs did not formally authorize establishment of burials until June 15, 1864 . Arlington did not desegregate its burial practices until President Harry S. Truman issued Executive Order 9981 on July 26, 1948 . </P> <P> The government acquired Arlington at a tax sale in 1864 for $26,800, equal to $410,000 today . Mrs. Lee had not appeared in person but rather had sent an agent, attempting to pay the $92.07 in property taxes (equal to $1,400 today) assessed on the estate in a timely manner . The government turned away her agent, refusing to accept the tendered payment . In 1874, Custis Lee, heir under his grandfather's will passing the estate in trust to his mother, sued the United States claiming ownership of Arlington . On December 9, 1882, the U.S. Supreme Court ruled 5--4 in Lee's favor in United States v. Lee, deciding that Arlington had been confiscated without due process . After that decision, Congress returned the estate to him, and on March 3, 1883, Custis Lee sold it back to the government for $150,000 (equal to $3,271,364 in 2017) at a signing ceremony with Secretary of War Robert Todd Lincoln . The land then became a military reservation . </P> <P> President Herbert Hoover conducted the first national Memorial Day ceremony in Arlington National Cemetery, on May 30, 1929 . </P>
