Doyle,
We may be speaking of the same records, but Sherman mentions in his "Memoirs" of a few Cavalry and 500 Negroes who were yet to receive guns, but tried to attack them (Union) with Axes and Hatchets.

I don't own this but, but read it on library loan, so I can't look up the exact details. Seems like it was AR or MO (bootheal) though.
