After the German invasion of Poland, the Polish and Kashubian population of Gdańsk Pomerania was immediately subjected to brutal terror. Prisoners of war, as well as many Polish intellectuals and community leaders, were murdered. Many of the crimes were carried out, with official approval, by the so-called "Volksdeutscher Selbstschutz", or paramilitary organizations of ethnic Germans with previously Polish citizenship. They, in turn, were encouraged to participate in the violence and pogroms by the Gauleiter of Danzig-West Prussia, Albert Forster, who in a speech at the Prusinski Hotel in Wejherowo agitated ethnic Germans to attack Poles by saying "We have to eliminate the lice-ridden Poles, starting with those in the cradle… in your hands I give the fate of the Poles, you can do with them what you want". The crowd gathered before the hotel chanted "Kill the Polish dogs!" and "Death to the Poles". The Selbstschutz participated in the early massacres at Piaśnica, and many of their members later joined police and SS formations which continued the massacres until the Fall of 1940.
