In 1899, an article appeared in the Gettysburg Compiler, giving an eyewitness account of the battle by Augustus P. Martin, commander of the Union Fifth Corps Artillery at Gettysburg. The article was actually an interview with Martin written by battlefield guide Luther Minnigh. It is impossible to say how much influence Minnigh had on Martin's account, but the story sounds strangely familiar.
"Among the interesting incidents that occurred on Little Round Top was the summary way in which a sharpshooter was disposed of in rear of the Devil's Den. He had concealed himself behind a stone wall between two boulders and for a long time we were annoyed by shots from that direction, one of which actually combed my hair over my left ear and passed through the shoulder of a man a little taller than myself who was standing behind me for a cover. At last we were able to locate the spot, by the use of a field glass, from whence the shots came by little puffs of smoke that preceded the whizzing of the bullets that passed our heads. We then loaded one of our guns with a percussion shell, taking careful and accurate aim. When the shot was fired the shell struck and exploded on the face of one of the boulders. We supposed the shot had frightened him away, as we were no longer troubled with shots from that location. When the battle was ended we rode over to the Devil's Den and found behind the wall a dead Confederate soldier lying upon his back and, so far as we could see, did not have a mark upon his body, and from that fact became convinced that he was killed by the concussion of the shell when it exploded on the face of the boulder...."
