A regiment of Union soldiers drawn up to watch an execution of an unknown individual or individuals, near Petersburg, Virginia, August 1864. Two recently dug graves can be seen to the right of the gallows presumably for the people about to be executed. Even though it was captured as a stereoscopic image, the photograph was taken at too extreme of a distance to show anything interesting when animated. By John Reekie.
