The Kentucky Legislature created the State Guard in May 1860. This allowed volunteer militia units to be organized in each county. This picture was taken at the first encampment at Louisville, August 1860. In the center wearing the top hat is Governor Beriah Magoffin. The Nelson Greys and Stone Riflemen were the Nelson County Units. Captain John Crepps Wickliffe of Bardstown commanded the Greys, and W. Davis McKay commanded the Riflemen.
