Henry’s army had needed over a month…

Henry’s army had needed over a month to reach the line of the Oder River, and once there, his troops encounter strong resistance led by Mieszko and his father.

Henry sends a delegation to the Polish rulers, in an effort to induce them to conclude a peace settlement.

Mieszko refuses, and after the Emperor's failure to defeat his troops in battle, Henry decides to begin retreating to Dziadoszyce.

The Polish prince follows in pursuit, and inflicts heavy losses on the German army.
