I don't know Johhny. He is a grandson of Captain Lemon, if memory serves, and had a good website on the 18th, but it was taken down for non payment, and Johhny seems to have disappeared. His e-mail has not worked for some time. I'd like to read Lemon's diary. Through Sharpsburg, the 18th was part of the Texas Brigade, so sources on it may have some info you haven't seen. Stan
