----- Houston

He was Medical Director of the 2nd Division, Second Army Corps on the Maryland Campaign of 1862 and served in the Division field hospital after the battle of Antietam on 17 September:

At Keedysville [MD] several houses were filled with wounded. We halted at the last one, used as a hospital by Sedgwick's Division. Every room in the house was filled with wounded, and every spot almost in the yard. This hospital was in charge of Dr. Houston, a good man who was trying to do all he could, but they had as yet received no stores, and were entirely without anything to eat. We gave them what we could spare.

His work in Maryland from Duncan,1 source also of the quote above, from the Reverend I. O. Sloan of the Christian Commission.

I have not yet identified this man beyond his last name.
