What is "kaczawa"

The Kaczawa is a river in the Lower Silesian Voivodeship in Poland. It springs from the Kaczawskie Mountains near Kaczorów and flows north and northeast through the towns of Świerzawa, Złotoryja and Legnica. Among its tributaries is the Czarna Woda. After a length of the Kaczawa empties into the Oder river at Prochowice.

Kaczawa between Legnica and Dunino was the site of the Battle of Katzbach on 26 August 1813 during the Napoleonic Wars.
