 However, Bückler was not kept in this dungeon, but in a prison cell above it.Bückler cut through the door boards with a secretly hidden knife and glued them back together again with chewed bread as glue.When a good opportunity arose, he left the cell, broke through a kitchen window loosely barred with iron, and from there jumped from the first floor into the moat of the city wall, dislocating his leg or breaking his fibula.
