The Saxon army directed against Demmin was led by several bishops, including those of Mainz, Halberstadt, Münster, Merseburg, Brandenburg, Olmütz, and Bishop Anselm of Havelberg. While their stated goal was to achieve the conversion of the pagans, most also sought additional territory and tithe for their dioceses; Abbot Wibald of Corvey went in the hopes of acquiring the island of Rügen. The Demmin campaign also included the secular margraves Conrad I and Albert the Bear, who hoped to expand their marches. A Royal Polish contingent wanted to add to the Bishopric of Lebus. Marching from Magdeburg, Albert the Bear recovered Havelberg, lost since the 983 Slavic rebellion. The crusaders then destroyed a pagan temple and castle at Malchow. After an unsuccessful siege of Demmin, a contingent of crusaders was diverted by the margraves to attack central Pomerania instead. They reached the already Christian city Szczecin, whereupon the crusaders dispersed after meeting with Bishop Adalbert of Pomerania and Duke Ratibor I of Pomerania.
