Here is another panoramic photograph that I digitized recently from the same patron. Supposedly, Wilson County resident, Fate Bass, is in this photo and you will win the prize if you can find him.
This is of the 156th Depot Brigade. The depot brigades trained and outfitted troops to be sent to the front lines of France during WWI.
Below is a panoramic photo of the 156th and their bivouacs from the Library of Congress, also at Camp Jackson and dated September 5, 1918.
