The Sleeping Army
During Catholic times, when there were still monasteries everywhere in the region, the monks in the monastery at Mönchsneversdorf led the most godless of lives. No woman in the entire region had peace from them. They forced people out of their beds, abducted them, and then made them excavate and shore up a large subterranean tunnel for them at night. This tunnel terminated near Putlos on the shores of the Baltic Sea. They often went there and acted wantonly with the wives of the sailors. Furthermore, the monks were said to have had a pact with the Devil.
Finally, their conduct and their misdeeds reached the ears of the king. Then he sent forth his men of war with orders to destroy the monastery. But the monks bewitched the army with their arts. The army thus moved into the subterranean tunnel and fell into deep slumber there. Here they shall sleep until one day the Turks shall have conquered the entire world. Then a white king will rule over our land who rides a white horse. His army will be the last one within all of Christianity, and it too shall be defeated. But then he will tie his horse to a willow tree and blow into his miracle horn. Soon after, the sleepers will awake, and an army will come up from the Neversdorf tunnel ready for battle and beat the Turks in such a manner that only seven of them will escape.
