Kadan then attacked Masovia, while Baidar burned the evacuated Polish capital, Kraków and then Bytom, and Orda Khan assaulted the southwestern border of Lithuania.

Baidar began to besiege the town, but marched north with Kadan and Orda to Legnica to defeat the forces of Henry II the Pious, Duke of Silesia and High Duke of Poland, before he could join King Wenceslaus I of Bohemia.

Mongol casualties were heavier than expected in the battle, however, and Kadan was reluctant to directly attack Wenceslaus' Bohemian forces.

While besieging Italian mercenaries defending Székesfehérvár, Kadan was forced to withdraw his troops after an early thaw flooded the land around the town.

Kadan was loyal to Kublai Khan and supported his army against Ariq Böke in the Toluid Civil War.

In many medieval sources, Kadan was mistranslated by chroniclers as Kaidu, leading to confusion about who participated in the European campaign.
