Monument to Robert E. Lee's Army of Northern Virginia at Gettysburg. That's Lee on his horse, Traveler. There are statues of this handsome and talented, yet tragic Southern general throughout the South. His wife was a Custis, and he lived in the Custis Mansion on a hill in what is now Arlington Cemetery. His property, which extended to the Potomac River, was seized after the Civil War. Thousands of unknown soldiers from the Civil War lie buried beneath a monument in his back yard.
