I have the information at home (I am currently in N.C., and live in Mississippi) so if someone doesn't answer before I get home, I will post it.
His diary is in the MDAH. His last entry before he passed away (2 days later in a VA field hospital) is something I memorised years ago:
"Let me die upon the field of battle in the front ranks as an example to those whose duty it is to free the South from the iron hand of tyranny. What care I, though my name may never be put in print, nor my country know I shed my blood for her freedom. What a worthless man is he who only acts to be seen of men. God sees and understands the honest heart."
Those last two sentences say a great deal.
