In the area around Bydogszcz (Bromberg) about 10,000 non-Jewish Polish civilians were murdered in the first four months of the Nazi occupation. This, the largest town in Pomerania had a population of around 140,000. Its priests, lawyers, teachers and industry leaders were arrested and executed in the town's square by machine-gun fire.
About 100 twelve to sixteen year old boy scouts were rounded up and machine-gunned to death on the steps of the Jesuit Church. For every German soldier shot, a group of between 50 and 100 Polish civilians were randomly selected and executed.
Participating in the shooting of hostages on September 10th, 1939, were members of the Police Battalion 6 (Berlin). Head of the SS, Heinrich Himmler, had said 'All Poles will disappear from the world'. In the provinces of Lodz and Warsaw, the SS conducted a total of 714 executions which took the lives of 16,376 Polish civilians, mostly the leading intelligentsia and aristocracy, civil and political leaders. In mental hospitals around Bromberg around 3,700 mental patients were shot. The most victimized class of Polish society was the clergy. In Pomerania, only 20 of its 650 priests were allowed to remain, the rest were either shot or sent to concentration camps. In Wroclaw, 49% of its priests were killed. In Chelmno, 48%, Lodz, 37% and Poznan, 31%.
In Warsaw 212 priests died at the hands of the invaders. The last transport of Jews from Bydogszcz arrived at the Warsaw Ghetto on March 10, 1941.
In September, 1939, Poland had a Jewish population of 3,351,000. Only 369,000 were alive at the war's end. In the post-war period the city of Bromberg was surrounded by a network of Soviet concentration camps the inmates of which were ethnic German nationals and residents of the region arrested between 1944 and 1950.
(On November 29, 1939, the USSR forced Soviet citizenship on all residents of Polish territory under their control)
Unable to stem the onrush of German forces during the invasion of their country, Polish soldiers and civilians started fleeing eastwards. It was during this flight to the east that the ethnic German civilians, resident in Poland for many years, received the full impact of the spite and hate stored up in the hearts of the retreating Polish soldiers and their civilian followers.
Between September 4 and September 8, 1939, in the communities of Eichdorf, Hopfengarten and Narzheim near Bromberg the polish soldiers began an orgy of murder and rape that is beyond belief.
German houses were entered and the occupants arrested and then murdered. Not all were shot, many were brutally put to death by all sorts of tools and their bodies severely mutilated. As the soldiers left to search for more German houses, their civilian helpers were left behind to plunder and steal and in most cases, to set the house on fire. Many of the German women were raped before being shot.
During this retreat from the west, the Polish soldiers, together with the communist civilian irregulars, were responsible for the deaths of many thousands of German residents.
At a later investigation, the testimonies of 593 witnesses established the fact that at least 3,841 named ethnic Germans were murdered by the Poles prior to the full German occupation. These revenge murders were carried out as early as April, 1939 in the Polish Corridor. In September, 1939 these Volksdeutsche formed themselves into Self-Protection units known as Selbschutz and came under the control of the SS and later under the Ordungspolizei (Order Police). The infamous reputation that it earned caused it to be disbanded on 30th of November, 1939.
These massacres were one of the causes that gave Hitler the excuse to invade.
