 However, the Elector did not support the monastery as expected; first he made excuses, then he elevated Hans to the rank of marshal and sold him the entire disputed possession.When the dispute with the monastery reached its peak, Hans had the nearby Wieslauter river dammed and so deprived the downstream town of Weissenburg (now French Wissembourg) of its water supply.The lord built the dam near the village of Bobenthal, five kilometres south of the Berwartstein.
