I have recently transcribed a Civil War letter that makes reference to "Rubber rugs" picked up off a battlefield left by Federal troops. I have my own thoughts, but I would appreciate a scholarly, referenced source (if possible) for this term and its application in a publication or some other source.

Thanks for any input or assistance.
