Was the engineer ever induced to give his story, does anyone know? Something of the flavor of this makes him sound not just anti-Union but as if he had a personal grudge, against someone specific? Well, it's Kilpatrick. You never know.
Must have been a huge concern- who was in charge of what transportation. This reminds me of another story, a nurse on a ship noticing it was allowed to trail behind a convoy, sounded an alarm. Transpired a plot was afoot, for its capture.
