The Mongol general in charge, Subutai, did not want the Polish forces to be able to threaten his flank during the primary invasion of Hungary.

[3] Orda's forces devastated central Poland, moving to Wolbórz and as far north as Łęczyca, before turning south and heading via Sieradz towards Wrocław.

[3] Baidar and Kadan ravaged the southern part of Poland, moving to Chmielnik, Kraków, Opole, and finally, Legnica, before leaving Polish lands heading west and south.

[3] Baidar and Kadan on 13 February defeated a Polish army under the voivode of Kraków, Włodzimierz, in the battle of Tursko.

[4] Henry, in order to gather more forces, even sacrificed one of the largest towns of Silesia, Wrocław, abandoning it to the Mongols.

[4] The Mongols turned from Wrocław, not finishing the siege, in order to intercept Henry's forces before the European armies could meet.

A European knight charge appeared to cause that section of the Mongol line to rout, thus leading Henry II to commit his cavalry to chase them.

The Mongols did not take Legnica castle but had a free rein to pillage and plunder Silesia before moving off to join their main forces in Hungary.

A legend that the Grand Master of the Teutonic Order, Poppo von Osterna, was killed during the battle is false, as he died at Legnica years later while visiting his wife's nunnery.

[9] The Templar contribution was very small, estimated around 68–88 well-trained, well-armed soldiers;[10] their letter to the King of France gives their losses as nine brother knights, three sergeants and 500 'men'—according to their use of the term, laity men at arms from the local secular dioceses.

[6] The death of Duke Henry, who was close to unifying the Polish lands and reversing their fragmentation, set back the unification of Poland.

It took place in the 14th century, and also meant the loss of Silesia, which would drift outside the Polish sphere of influence (and gradually become a part of the Bohemian Crown[11]).

[citation needed] Northwestern Rus princes complained to the occupying military Mongol masters about the repeated attacks from the Kingdom of Poland.

Ozbek Khan and Jani Beg warred with the powerful kingdom of Poland to secure their claim on western Rus (modern Belarus and Ukraine).

[14] Towards 1356, Casimir III the Great reached an agreement with the Golden Horde and apparently undertook to pay tribute in exchange for military support against Lithuania.
