...As a result, Polish children were refused admission to public Polish-language schools and premises were not allowed to be rented to Polish schools and preschools. Due to such policies, only 8 Polish-language public schools existed in the city, and the Poles managed to organize 7 more private Polish schools. However, in 1937, Poles who sent their children to private Polish schools were demanded to transfer children to German schools, under threat of police intervention, and attacks were carried out on Polish schools and Polish youth.


When Danzig united with Germany in September 1939, only 1,600 Jews were left in the city. Emigration continued until the fall of 1940 and at the end of February 1941, the city's remaining 600 Jews were deported to their deaths in Poland.

In September 1939, the Germans established the Stutthof camp in a wooded area west of Stutthof, a town about 22 miles east of Danzig.

The camp was established in connection with the ethnic cleansing project that included the liquidation of Polish elites such as members of the intelligentsia as well as religious and political leaders.

The camp staff consisted of SS guards and, after 1943, Ukrainian auxiliaries.
The SS in Stutthof began conscripting women from Danzig and the surrounding cities in June 1944, to train as camp guards because of their severe shortage after the women's subcamp of Stutthof called Bromberg-Ost was set up in the city of Bydgoszcz. One such woman became Wanda Kalacinski. After she finished school in 1938, Wanda worked in a jam factory until 1942. The same year she married Willy Klaff and became a housewife and then a tram conductor. This changed in 1944 when she became a guard in Praust, the subcamp of the Stutthof.
She held the same position at Russoschin, another Stutthof's subcamp, where she arrived on the 5th of October 1944. In both camps Klaff became infamous for her brutal treatment of prisoners whom she would beat and kick without any reason at all until they lay still. When she was in particularly bad mood, she would drown the female inmates in mud or club them to death.

Wanda Klaff had escaped from the camp in early 1945. In June of the same year, she was arrested at her parents' home and soon after, she fell ill from typhoid fever in prison.

Klaff was then tried at the First Stutthof trial which began on the 25th of April 1946. During the trial she said: "I am very intelligent and I was very devoted to my work in the camps. I struck at least two prisoners every day." Having made this statement, she was probably the only one to think so.
The trial ended on the 31st of May and Wanda Klaff was sentenced to death by hanging.

Her execution was held publicly and became a theater of horror which was recorded by official press photographers.
