The Custis-Lee mansion was once home to Gen. Robert E. Lee, whose decision to back his home state of Virginia in the Civil War resulted in great loss of life. Brig. Gen. Montgomery C. Meigs, in charge of interring the dead, seized Lee's land. Some saw his recommendation to use the Mansion as a burial ground for Union troops as an act of revenge on his old colleague Lee, who he regarded as a traitor. The land is now Arlington National Cemetary
