A Soldier Who Was Said to Have Been Killed by an Artillery Shell During the Battle of Gettysburg (1863)

The bloated, disemboweled, and partially dismembered body of an unidentified soldier who was said to have been killed by an artillery shell during the Battle of Gettysburg at the Rose Farm, July 1863. Different sources say different things about which side the soldier fought on. As to where his severe wounds may have really come from, leading Civil War photography expert William Frassanito has surmised that the body might have been a victim of scavenging hogs in the days after the battle. The artillery shell and bayoneted musket are also thought to have been items found elsewhere by the photographer for the purpose of posing them with the body. By Alexander Gardner. Animated stereoview.

This half stereoview is said to show British soldiers taking prisoners in what is almost certainly another staged scene. The bodies of German soldiers seen in the posted animated stereoview above disappear in a scene that was presumably meant to portray the aftermath of fighting in the bunker. Not sure if the two were released in the same stereoview series, but this one was published by Realistic Travels.
