Soldiers sit and stand among two large field desks featuring a myriad of compartments filled with papers and folios. One of the men, wearing a frock coat with captain's shoulder straps, sits in a camp chair and holds a small dog in his lap. A large tent is set up under a tree-built structure providing shade and shelter for the subjects.
