This photograph of the Gettysburg battlefield was selected from an album attributed to Mathew Brady. However, many were not taken by Brady himself, but by his team of unrecognized assistants or by former associates.
For example, one of the battle's most memorable images depicts a "rebel sharpshooter at Devil's Den." It was shot by Timothy O'Sullivan, who arrived at Gettysburg two days after the battle ended. Modern research indicates that the body and rifle (not one used by sharpshooters) were also photographed at another location, suggesting that they were most likely moved to Devil's Den, a site used by Confederate sharpshooters.
