Bruce,

What became of men held at Gratiot for various guerrilla acts or other specific violations at the end of the war? I'm thinking of folks who were identified as having committed various serious punishable offenses of a direct nature. Were they released? Required to take oath and released? Tried? Serve time for offenses and later released? Were some executed after the end of the war?

I suppose the "end of the war" cut off date in this instance would be about the time the Trans-Mississippi forces finally surrendered.
