natives of Bydgoszcz. Eyewitness accounts have been criticised by Richard Blanke. In 2004, Chinciński discussed previously unpublished reports of Polish Army Pomorze, which reported "a large scale diversion" in Bydgoszcz on September 3 and numerous smaller incidents in surrounding area around that time. A number of Polish and German historians discussed the problem September 4, 2006, at the German Historical Institute in Warsaw. Chinciński discussed newly discovered documents of the Abwehr that show that there were indeed plans for fifth column and diversion activities in Bydgoszcz; several paramilitary groups were organized by Germany in the city, he discussed the bias of the Polish communist era historiography, which minimized cases of Polish mob lynching of ethnic Germans, which did occur in Bydgoszcz. German historian Hans-Erich Volkmann noted problems with German historiography, outlining some of the unreliability inherent in early post-war studies, which were still significantly affected by the Nazi era, and that the Bydgoszcz events were and still are used for political purposes. By 2007 after several years of studying German archives, documents were uncovered in which General Erwin Lahousen praised action of German saboteurs in Bydgoszcz and organized delivery of supplies and medical help to them. German historian Jochen Böhler, in his publication about the invasion of Poland, published in 2006, wrote that new documents uncovered from the German archives proved that Polish soldiers were attacked by Abwehr Agents and members of the German minority.
