Despite the peace of Poznan, warfare between Bolesław I and Henry II continued between 1007 and 1013. In 1007, Bolesław I again took control of Lusatia with the fortress of Bautzen. A campaign led by Henry II in 1010 was unsuccessful. During this campaign, which started in Belgern, Henry II was struck by an illness at Jarina castle and returned with some of his bishops, while the remaining armies devastated the surrounding area. A Saxon campaign in 1012 was also unsuccessful. Henry II had mobilized the Saxon nobility to mount campaigns in his name, since he needed a peace agreement before 1013, when his coronation in Rome was scheduled.
