I did find this
1915 history of Dearborn County, that suggests that Morgan's Raid through that area was nearly bloodless, apart from a blue-on-blue incident at Hardintown Schoolhouse (p. 331-32), where six Union soldiers were killed and eighteen wounded when units, rushing into position and fearing Morgan's men coming down on them in the dark, fired into each other.
I did, however, get a chuckle out of this:
Dearborn county, in this one event, deserves all the credit it ever received. Its people were loyal. The invader was met with armed force, none refusing to assist. . . . Occasionally, [though,] in the line of the raider's travel, they would find some person who would endeavor to curry favor by claiming sympathy with the rebel cause, thinking to evade loss or to secure gain. One case afterwards was reported that was humorous. A man of this kind thought it wise, as the rebel forces passed on the highway, to hurrah for Jeff Davis with all of his might. The rebel chieftain and staff happening to ride by at that time, dismounted and assured him that they were just looking for him; that a friend was what they wanted. They were needing a good dinner and, of course, if he was their friend he would be delighted to get them up a good meal. The would-be sympathizer pleaded his wife's sickness, his want of wood for fuel, and other reasons, but the chieftain was immovable. He was ordered to cut wood and upon refusing, a guard was detailed which, with bayonets, stimulated his industry all that hot afternoon. while with a saw and buck he provided the necessary wood and his good wife and family cooked for the raiders. It was safe to say afterward that this man had no sympathy for the cause of the Confederacy.
