Why would you exchange prisoners while the fighting is still going on? You can expect soldiers from both sides to be back on the battlefield within a month or two. After the war is over? Yes, of course. While its raging? Someone is smoking crack. Its almost like winning isn't the objective. Continued warfare is.
