Przemysł II
Fortunately for Henry IV, the reaction to his imprisonment was indignation. Ottokar's Polish allies, Duke Henry III of Głogów and Duke Przemysł II of Greater Poland attempted to enforce Henry IV's liberation. The Bohemian king however only sent febrile appeals and request for release. Henry IV's allies were defeated by Duke Bolesław II 's son Henry V the Fat in the bloody Battle of Stolec (24 April 1277), where both Dukes Przemysł II and Henry III were captured.
