But the concept of the Knight Guard collapsed by 1224 as a result of the defeat of the Lesser Poland knights, who suffered a surprise attack from the Prussians. The defeat and slaughter contributed significantly to the already cowardly attitude of the command of the Guard, a member of the Gryfici family, who was punished with exile.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

The war between Leszek and Henry I was preempted because of an attack on <a href="/wiki/Lubusz_Land" title="Lubusz Land">Lubusz</a> by the Landgrave <a href="/wiki/Louis_IV_of_Thuringia" class="mw-redirect" title="Louis IV of Thuringia">Louis IV of Thuringia</a>, which forced Henry I to retreat. Before he could leave <a href="/wiki/Lesser_Poland" title="Lesser Poland">Lesser Poland</a> his troops had wanted a clash with the forces of Leszek and Konrad at the Dłubnia River. Such a battle did not occur, however, because the opponents were able to conclude an agreement. It was recognized, though, that a return to the previous alliance and close cooperation that lasted from 1217 to 1224 would no longer be possible.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

Leszek was personally interested in this conflict, as he still hoped to inherit the domains of the childless Władysław III. For unknown reasons, at some point Władysław Odonic lost the support of Swietopelk II, and thus he could not be sure of a victory. Therefore, it was unsurprising that both parties sought to end the conflict. Another problem that Leszek wanted to solve was the issue of the dangerous independent behavior of the Pomerelian Duke.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.
