One group, under the notorious Henry Dillingham, was sent by Davis near the end of the war to occupied Kentucky and Missouri to destroy a key bridge and any federal transportation they could. They were known to use the "coal torpedos" and several sources say one was used to blow up the "Sultana" in April 1865. It was in the area Dillingham was operating in and it was ferrying ex-confederate prisoners of war at the time it was destroyed.
