Battle of Annaberg

1921 battle of the Third Silesian Uprising

The Battle of (the) Annaberg was the biggest battle of the Silesian Uprisings. The battle, which took place between May 21–26, 1921, was fought at the Annaberg, a strategic hill near the village of Annaberg O.S., located southeast of Oppeln (Opole) in Upper Silesia, Weimar Germany. After the hill had been captured by irregular Polish-Silesian units in the Third Silesian Uprising, German Freikorps pushed the Polish forces back. The final border was determined by political and diplomatic efforts.
