Maybe he came to Arkansas looking for his brother and was picked up to serve since he had a short service period.
He was also active in the G.A.R. and I have a picture of him with a large display of his collection of Medals. As far as I know nobody in the family has any of them.
Asher died in 1926 and is buried in Oakwood Cemetery Tuscumbia Alabama in the Bresler Plot. His memorial is posted on Find-a-Grave.
