The Mongols win at Legnica
A Mongol army raiding Poland crushed the forces of Duke Henry II the Pious of Silesia, which included German knights and members of the military orders, near Legnica. Henry was killed. The raid was meant to stop help reaching Hungary, where the main Mongol army won a great victory two days later. The date is by the Julian calendar.
