Sheldon had been injured in a fierce battle and was left for dead in a muddy, blood-soaked pasture somewhere in Georgia. He was a mere lad of fifteen. He lay there for two days, by his reckoning, only to slip into unconsciousness and fever. He was rescued from this field by another lad who had also been separated from his company.
