Fitzhugh Brundage, author of A Fate Worse Than Hell, explains that prisoner exchanges were based on 18th-century European customs that sought to prevent the execution or enslavement of captured enemies. Armies used a calculus to trade soldiers, such as equating one colonel to twenty privates to ensure equity. When capture numbers were uneven, the parole system allowed surplus soldiers to return home on the condition they not fight until formally exchanged. This formalized process aimed to keep warfare humane and efficient for both sides until political tensions arose. (2)
