Believing the Wendish incursion showed the Queen was weak, Duke Eric rebelled. The queen was forced to raise another army and march to Jutland to put the Duke in his place. She defeated the Duke, and while he negotiated a truce with her, he gathered allies in northern Germany to help him attack. The combined forces defeated Queen Margaret in 1261 at the Battle of Lohede south of Danevirke in Schleswig-Holstein. She and her son were captured and were forced to cede royal properties in southern Jutland to secure their release.
