The town council now sent deputies to the Protestant princes, Dukes Ernest and Francis of Lüneburg, the Landgrave Philip of Hesse, and Count Philip of Waldeck, brother of the prince-bishop, to promise the adhesion of the city to the Smalkald union, and to request their assistance against their bishop. The situation was singular. The city sought assistance of the Protestant union against their prince, desiring to overthrow his power, under the plea that he was a Catholic bishop. And the bishop, at heart a Lutheran, and utterly indifferent to his religious position and responsibilities, was determined to coerce his subjects into obedience, that he might retain his rank and revenue as prince, intending, when the city returned to its obedience, to shake off his episcopal office, to Lutheranize his subjects, and remain their sovereign prince, and possibly transform the ecclesiastical into a hereditary principality, the appanage of a family of which he would be the founder. He had already provided himself with a concubine, Anna Pölmann, by whom he had children. Whilst the senate was engaged in treating with the Protestant princes, negotiations continued with the bishop, at the diets convoked successively at Dulmen and Wollbeck, but they were as fruitless as before. The deputies separated on the 9th December, agreeing to meet again on the 21st of the same month. At this time there arrived in Münster a formal refutation of the theses of Rottmann, by John of Deventer, provincial of the Franciscans at Cologne.[81] The magistrates had repeatedly complained that "the refusal of the Catholics to reply to Bernard Rottmann was the sole cause of all the evil." At the same time they had forbidden the Catholic clergy to preach or to make use of the press in Münster. This answer came like a surprise upon them. It was carried by the foes of the clergy to the magistrates. The news of the appearance of this counterblast created the wildest excitement. "The citizens, assembled in great crowds, ran about the streets to hear what was being said. Some announced that the victory would remain with Rottmann, others declared that he would never recover the blow." [81] Kerssenbroeck, p. 332. The provosts of the guilds hastily drew up a petition to the senate to expel the clergy from the town, and to confiscate their goods; but the magistrates refused to comply with this requisition, which would have at once stirred up civil war.[82] [82] _Ibid._ pp. 335-7.
