As the war dragged on into 1863 "How a Free People Conduct a Long War" became a popular booklet.  Widely published and distributed to troops in the field by the Sanitary Commission and other aid societies, it is likely that few U.S. Army camps lacked a copy in the latter years of the war.  This facsimile version of an early edition from 1863 printed in Philadelphia includes digitally cleaned text formatted into folded signatures and hand stitched together as per the original, with yellow paper wrappers glued on.
