The Fredericksburg National Cemetery is the final resting place for over 15,000 United States soldiers. Most of the soldiers died during the Civil War, but there are about 100 20th century soldiers and a couple of spouses. The cemetery was officially closed to further burials in the 1940s. The Union Civil War soldiers buried here include those who died of illness in the camps around Fredericksburg, in the four major battles around Fredericksburg as well the Mine Run and North Anna campaigns. Only about 20% of the soldiers are identified. Confederates who died in the Fredericksburg area were interred in Confederate cemeteries in Fredericksburg and Spotsylvania.
