   • 1947 July, J.F.L., “Tenting Tonight”, in Infantry Journal, page 37:

     Colonel Elbridge Colby in Army Talk tells us that the shelter-half, or “pup tent” made its debut during the Civil War. It seems to have been first christened “pup tent” by the Sixth Iowa Infantry at Memphis in 1862 and appears to stem etymologically from the same soldierly self-ridicule that resulted in such terms as “dogface” and “dog tags.”
