This is the first of two photographs from the display at the visitor center at Shiloh National Battlefield.
The caption under this picture in the display reads: “Men of the 9th Indiana, a regiment of Hazen's brigade in the Army of the Ohio, in camp before the battle.”
Perhaps, partially due to the size of the photo on display (about 30x36 inches), it is out of focus.
The close-ups below begin from the left hand side of the above photograph. There is some overlap in the close-ups so some men will appear on more than one of the pictures.
Though out of focus, it is interesting to see the different stances and postures of the men. How some of them seem to be paying attention, and others, well not so much.
