As colonel of Hegauer farmers, he was involved in mid 1524 until the end (in July 1525) where they failed siege of cell (Radolfzell) on Lake Constance there.
Radolfzell is a well known health care city (Mettnau) and an important railway junction of the Upper Rhine Railway and the Hegau-Ablach Valley Railway (leading to the Bodenseegürtel Railway).
It receives support from the Sielmann Foundation and works closely with western partners, including the Vogelwarte Radolfzell with which it operates a joint trapping and banding station.
