Ottokar I of Bohemia
Sverker's kinsman, King Valdemar the Victorious of Denmark provided Sverker with auxiliaries, including a Czech contingent from Valdemar's father-in-law, King Ottokar I of Bohemia. The bulk of the troops, however, were gathered by Sverker's in-laws, the powerful Sunesen brothers. The army was led by Ebbe Sunesen, brother of Archbishop Andreas Sunesen. Medieval traditions estimate the size of the force at 12,000 or 18,000, although these numbers might be vastly exaggerated.
