It isn't like they were going to go anywhere.
Here is some Tennessee home front lore:
Three German submariners who escaped from Crossville came upon a mountain cabin. Out came "granny," who told them to "git." When they did not leave, she shot one of them dead. When a local deputy arrived and told her of the circumstances, the woman sobbed, claiming she would never have fired had she known they were Germans. "I thought they wuz Yankees," she said.http://tennesseeencyclopedia.net/entry.php?rec=1076
That’s hilarious.
