This is Devils Den in the Civil War, 1909, and today. It was supposedly formed 200 million years ago by glacier activity. During the battle it was held by the Union Army initially but they were eventually driven out after hard fighting by Hood's Texans late on the afternoon of July 2nd 1863. Devils Den and the slaughter-pen were near Little Round Top.

Alfred Waud was a Civil War sketch artist working for Harpers Weekly. He was born in London in 1828 and died in 1891. Newspaper artists were the equivalent of modern day combat photographers because the technology was not available to transfer photographs to newspapers. This is the Alfred Waud rock in Devils Den and one of his combat sketches.
