Fred,
I think the location you refer is also called
Whistler; the action occurred there Apr 13, 1865;
the Union participants were elements of the 91st
Indiana Vols, 7th Vermont and 29th Iowa; losses:
Union, 1 killed and 2 wounded; I have yet to
find just which Confederate unit was involved,
but their losses were 4 killed and 2 wounded.
