Devil Anse and his uncle Jim Vance later formed a Confederate guerrilla fighting unit called the "Logan Wildcats." One of the group's victims was Union General Bill France; killed in revenge for losing one of their members to France's unit. In 1865, he was suspected of having been involved in the murder of his rival Asa Harmon McCoy, who had fought for the Union Army and was waylaid by The Wildcats on his return home. Hatfield had been home ill at the time of the killing, which was probably committed at the instigation of his uncle, Jim Vance. This may have sparked the beginning of the notorious feud between the two families that claimed many lives on both sides.
