"Angel's Glow" the mystical Shiloh event solved.

The Battle of Shiloh was one of the bloodiest in the entire Civil War. It was a constant, two-day struggle that left little time for the medics to tend for the wounded, and the massive amount of wounded soldiers meant that many of them would be left just lying on the battlefield for days. As the wounded men lay in agony, a strange thing happened: Some of their wounds started glowing. The eerie sheen was clearly visible in the dark, and no one could understand what was happening. However, the strangest part happened when the medics actually started treating the wounded: The soldiers with glowing wounds were healing much better than the ones with normal, non-glowing injuries.

The phenomenon soon became known as Angel’s Glow. Its nature remained a mystery, and many suspected the healing shine was actually divine in origin.

The strange secret of Angel’s Glow was finally solved in 2001 by two high school students who were investigating the phenomenon for a science fair project. They figured out that the glow on the wounded soldiers was most likely Panellus stipticus, a ”good” bacteria with bioluminescent properties that was transported to the wounds by the many insects that were infesting them. Although P. stipticus wouldn’t usually survive in human body temperature, it was able to survive in the hypothermic wounded soldiers, allowing it to fight the bad bacteria that were trying to infect their wounds. Initial story from an email I received. I was not aware of Angel's Glow...

This was a wet swampy region, which meant many of the wounded spent their waiting hours lying in mud and foul water. To compound their misery, it also rained part of the time, especially the first night. All told, it took two days and two nights for all the wounded to be recovered from the battlefield at Shiloh.

So what does this have to do with Angel's Glow? Good question...

During the night, as men lay in the mud, muck, and rain, too wounded to crawl to safety, something strange began to happen...

Interesting. My only question is if there is a correlation between these bacterium and the prevalence of swamps/bogs organic preservation properties.
