Old Hickory let me borrow his division book, a sort of "yearbook" for the men of the 30th ID. The book has a good history of the division and several maps and good many pictures, but is showing it's age. It is very brittle. I will scan the maps and anything else that looks good.
Here is a picture of Old Hickory in the book, but you can't really see his face. He is lying down, denoted by the arrow.
The other men are from the left:
unknown (upper corner)
unknown (thinks he was from another outfit, only head is visible)
Goodrich Sims (with carbine)
Guy Cook (on stomach)
unknown (seated by the beer barrel)
RB Malone (lying back, hands behind head)
Wilkerson (along wall, yawning)
Sutton (along wall, chin on hand)
Unknown (looking at camera)
Guy Cook was the driver for Col Johnson of the 117th Infantry Regiment. Old Hickory does not remember why Mr Cook was there with them that day. He had been part of the Mech Cav Squadron and had been transferred.
Edit - - Re-read the caption. Apparently that was a wine barrel and not beer.
