In September 1941, about 3,000 Jews were murdered in a forest area called Wygoda, about five kilometers north of Kazimierz Biskupi and a few kilometers south of Kleczew. Those who carried out the murders were Sonderkommando Lange, who later in the year became responsible for the first Nazi extermination camp at Chelmno. In Wygoda, Lange experimented with a murder technique, which meant that the Jews were forced into a pit then filled with slaked lime (corrosive substance) and the Jews were burned to death. The method was abandoned because it was considered too problematic because it required large amounts of water. No consideration was given to the victims.
