The forces attacking Dobin included those of the Danes Canute V and Sweyn III, Archbishop Adalbert II of Bremen, and Duke Henry the Lion of Saxony. Avoiding pitched battles, Niklot ably defended the marshland of Dobin. One army of Danes was defeated by Slavs from Dobin, while another had to defend the Danish fleet from Niklot's allies, the Rani of Rügen. Henry and Adalbert maintained the siege of Dobin after the retreat of the Danes. When some crusaders advocated ravaging the countryside, others objected by asking, "Is not the land we are devastating our land, and the people we are fighting our people?" The Saxon army under Henry the Lion withdrew after Niklot agreed to have Dobin's garrison undergo baptism.
