334 HISTORY OF THE I3TH [Tenn.] REGIMENT
Stain on his soul that no amount of ablution could cleanse !
About a month later the rebel soldiers killed a young
man named Berry Pritchard a mile east of Elizabethton,
at a place called "Island Creek." He was accused of
being a bridge burner. Pritchard's home was on Stony
Creek. He is said to have been killed by Capt. R. C. Bo-
zen's men. Motte and Duff were also said to be con-
nected with this crime. This officer was said to be from
Grayson county, Va., and like most other Confederate
officers who were sent into these counties seemed to re-
gard the murder of Union men as a praise-worthy em-
ployment, especially when they were unarmed and de-
fenceless. Bozen was charged with the murder of Wil-
liam Thompson, whose home was in the Greasy Cove,
Carter county, but who, fearing to be found at home,
had come to the vicinity of Elizabethton. Wishing to do
something to pay his board he went into a field to gather
corn. He was captured by Bozen's men, placed on a
mule and taken to his home several miles away. After
torturing him in various ways they took him a short
distance from home on the farm of a rebel citizen named
Brown and shot him to death. We are not advised as to
the crime charged against Thompson. If the Bible be
true there will be an investigation at the day of judg-
ment, and Bozen will say to the mountains and rocks,
"Fall on me and hide me from the face of Him that sitteth
on the throne and from the wrath of the Lamb."
