A Mighty Fortress of God

In February 1534 the catholic Bishop Franz von Waldeck provoked by the establishment of an Anabaptist enclave in the North Rhine Westphalian city of M nster sought to regain control of his diocese laying siege on the city. For the first time, thanks to eyewitness accounts, a Mighty Fortress provides an insight into the stages of the siege detailing the failed assaults, the erection of a ring of earthworks and finally the act of treachery which caused the collapse of a sixteen-month defence by the Anabaptists.
