Art. 53. The enemy's chaplains, officers of the medical staff, apothecaries, hospital nurses and servants, if they fall into the hands of the American Army, are not prisoners of war, unless the commander has reasons to retain them. In this latter case, or if, at their own desire, they are allowed to remain with their captured companions, they are treated as prisoners of war, and may be exchanged if the commander sees fit.
