Baidar

He commanded the Mongol army assigned to Poland with Kadan and, probably, Orda Khan.

The Poles were heavily defeated and Boleslaw with a part of his troops fled to Moravia.

On Palm Sunday the Mongols set the town on fire and took prisoner large numbers of the people who had remained.

Moving further west, Orda and Baidar reached a place east of Opole, where they forced Duke Mieszko the Fat's army to retreat.

Early in May 1241 they entered Moravia, then continued via Brno, to join Batu Khan's main army in Hungary.
