The Battle of Shiloh’s Angel’s Glow: Fact, Civil War Legend or Modern Myth? 

It sounds like the script for a Hollywood movie. The story, first appearing in 2001, begins with a purported civil war legend from the Battle of Shiloh. The legend said that the wounds of some soldiers glowed (faintly) in the dark. Soldiers with these glowing wounds were more apt to survive, giving the phenomenon the name “Angels Glow”. The story ends with two curious teenagers solving the mystery using their science fair project. They identify infection by the bioluminescent bacteria Photorhabdus luminescens (formerly Xenorhabdus luminescens) as the likely cause of the glowing wounds. P. luminescens produces bacteriocins (antimicrobial peptides), which the teenagers attribute to helping keep other infections at bay, resulting in the improved survival rate for the soldiers whose wounds glowed.

The teenagers win. The mystery is solved. The credits roll. 

Except life (and science) is rarely as simple as a summer block buster.

If battlegrounds could speak they would have many stories to tell.  In some cases the microbes found in those soils have lived on to separate fact from fiction. One such story has its origins in the Battle of Shiloh, which went down in history as one of the bloodiest battles fought during the American Civil War.  As the soldiers lay mortally wounded on the cold, hard grounds of Shiloh waiting for medical aid, they noticed a very strange phenomenon. Some of the wounds actually appeared to be glowing in the dark casting a faint light into the darkness of the battlefield. And the legend goes that soldiers with the glowing wounds had a better chance at survival and recovery from infections than their fellow brothers-in-arms whose wounds were not similarly luminescent. The seemingly protective effect of the mysterious light earned it the moniker “Angel’s Glow.”

Fast forward to the 21st century.
