Angel’s glow at Shiloh
Following the battle of Shiloh, some of the soldiers noticed that their open wounds glowed in the night. In the days that followed, they observed that those wounds more readily healed than the others. The fortuitous phenomenon was called angel’s glow.
Micro-organisms were barely known then. They had neither the science nor technology to investigate what was happening. Today’s microbiology is more advanced, and likely credits a bioluminescent bacteria and its commensal nematode.
