#freikorps

May 26 1921, Oppeln [Góra Świętej Anny]–The Polish and French had attempted to prevent Freikorps from reaching Upper Silesia, but were only able to delay them by a few weeks.  On May 21, the Germans launched an attack on the Annaberg hill, which dominated the surrounding Oder valley.  They were able to take the hill and hold it against Polish counterattacks, but a lack of artillery prevented them from pushing much beyond it.  The Poles officially abandoned their efforts to retake the hill on May 26, and fighting only continued on a limited basis for the next month.  The final division of Upper Silesia would largely follow the German-Polish lines after the battle.
