Question: Context: 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.
