Lisa my great great grandfather had 2 brothers and 2 step brothers in the 4th Ky. Infantry Union. One was medically discharged after the Battle of Stones River. He returned to his home in Estill Co., Ky. He returned to the Army in 1864 citing "because of guerilla activity in central Ky he felt safer in the Army". He says this in his pension file. He was later captured after the failed cavalry raid at Newnan, Ga. So guerilla activity was a serious problem in Ky. I'll give you this statement from his file if you so desire.
