I can point you to images of brush arbors used at this time by Civil War soldiers while encamped. Although the context is completely different, they provide a very good idea of what the arbors looked like. See Martin C. Perdue, "Shelters in the Civil War Landscape," Perspectives in Vernacular Architecture IX (University of Tennessee Press, 2003), 101-15, esp. 103 and 104.
