Soldier's Home National Cemetery

From www.exploredc.org:

Soldiers' Home is still a residence for retired veterans. One of the first cemeteries established during the Civil War, Soldiers' Home National Cemetery, is also on the site. In 1864, there was no more burial space left on its six acres, a shortage that led to the establishment of Arlington Cemetery on the grounds of Robert E. Lee's estate across the Potomac River in Virginia. Among those buried here are Union General John A. Logan, who later represented Illinois in the House of Representatives and the Senate.
