The conflict certainly was not trivial, since Bolesław did not regain his freedom until 20 April 1253, thanks to the pressures of the powerful Greater Poland clergy. The final reconciliation between the brothers occurred in May of that year at a meeting in Pogorzelica near Giecz, where thanks to the mediation of Pełka, the Archbishop of Gniezno Bolesław recovered his Duchy of Kalisz-Gniezno. After that the brothers cooperated without problems, but Bolesław was still removed from the foreign policy of Greater Poland. On 8 May 1254, Bolesław took part in the national Congress of Piast princes at Kraków on the occasion of the canonization of St. Stanislaus, where they decided to form a coalition against Swantopolk II, Duke of Pomerania. Among the princes who participated were his brother Przemysł I, Casimir I of Kuyavia, Siemowit I of Masovia, Władysław of Opole and Bolesław V the Chaste. In September of that year Bolesław participated in an expedition against Henry III the White launched by his brother and Konrad I of Głogów.
