Lee Requests A Favor From Grant and the body of Captain Robert Beale Davis is moved between the lines
Grant Gates, retired Chief of Interpretation at Petersburg National Battlefield, pointed out that this drawing by Frank Leslie's Illustrated Weekly artist Joseph Becker depicted a wooden headboard with a legible name- Captain Davis of a Virginia regiment, seemingly the 48th. Who was Captain Davis? There was no officer of that name in the 48th Virginia. This was likely the original battlefield grave of Captain Robert Beale Davis of the 40th Virginia, as revealed in the correspondence below in the Papers of Ulysses S. Grant. Davis was killed on October 1, 1864, during the battle of Peebles farm.

In many cases bodies were recovered from the battlefield by enemy burial groups under a flag of truce, but this didn't always happen. Davis's family and friends were lucky that his grave was marked, perhaps by his own men, and that Lee was willing to intervene and Grant facilitated the exhumation. Parties were not to enter the enemy's lines for even the gravest purposes.
Captain Davis was buried a few miles away from his place of death at Blandford Cemetery.
