The Pomeranian Crime of 1939
In the first months of World War II, mass executions took place in the pre-war Pomeranian Voivodeship, resulting in the deaths of 20 to 30 thousand people. The number of victims in this region was twice as high as in other areas of pre-war Poland. The victims, including priests, teachers, politicians, merchants, officials, as well as the mentally ill and representatives of the Jewish community, were buried in mass graves in order to erase the traces of the crime.
Dr Dawid Kobiałka’s research project attempts to analyse this tragic legacy by using an interdisciplinary approach combining the work of specialists in such fields as archaeology, history, ethnography, physical anthropology, genetics, chemistry, soil and plant analysis, and many others.
The Germans murdered Polish citizens in approximately 400 towns in the pre-war Pomeranian Voivodeship. The idea of the project was to thoroughly research the past and present heritage of four places related to the Pomeranian Massacre of 1939. Monuments, places of internment, prisoner transport, executions and mass graves were documented and their contemporary role and significance was analysed. Family heirlooms, which, as material carriers of memory, constitute unique testimonies of the past, also constituted an important element of research. Archaeological, historical and ethnographic approaches complemented, verified and influenced each other in the course of the research work.
The project used forensic archaeology methods, treating mass execution sites as archaeological sites. Finds such as bullets, shell casings, personal belongings of victims and fragments of remains allow for the reconstruction of key aspects of these crimes and their consequences. This research aims not only to document, but also to reflect on how the legacy of these tragic events affects the present day.
It is a unique attempt to combine archaeological data with other sources – historical, visual and material – in order to better understand and commemorate the Pomeranian Massacre of 1939.

Report from the Death Valley in Chojnice
The Communication and PR Centre team of the 91µÎµÎ visited with a camera the site of archaeological works at the mass grave of murdered patients of the National Social Welfare Centres in Chojnice in July 2024. During the visit we talked with Dr Dawid KobiaÅ‚ka – the project manager, Dr Tomasz Ceran – a historian, Head of the Historical Research Department Institute of National Remembrance, Branch in Bydgoszcz and the project implementer responsible for historical research, Dr Joanna Rogóż – a physical anthropologist, Laura Muñoz-Encinar from the and – a specialist in the archaeology of contemporary conflicts and forensic anthropology, and prosecutor Tomasz Jankowski from the Branch Commission for the Prosecution of Crimes against the Polish Nation in GdaÅ„sk.
We had the opportunity to see with our own eyes the skeletons of the victims, which were carefully and systematically described, examined and excavated. We watched closely as Dr Kobiałka's team, with extraordinary accuracy and respect, reconstructed the stories of the victims whose fate and, above all, their resting place remained unknown for decades.
The testimony to this one-day visit is a short report that synthetically shows the enormity of the work carried out by the researchers. The report not only presents the details of the research methodology but also highlights the emotional dimension of the team's work. It is an invitation to reflect on the difficult legacy of the 1939 Pomeranian Crime and a reminder of the duty of remembrance that rests on future generations.
