During the German occupation of Poland (World War II), the Kaliska forest was the site of large massacres of Poles, carried out by the Germans from September to November 1939 as part of the Intelligenzaktion.[2] Among the victims were Polish teachers, policemen, activists, local officials, dentists, postal workers, foresters, priests, and other inhabitants from Kartuzy, Żukowo and various nearby villages.[2]
