Skeletal evidence of the ethnic cleansing actions in the Free City of Danzig (1939-1942) based on the KL Stutthof victims analysis

In the early days of World War II, many of the prominent and influential people of Polish nationality from the Free City of Danzig were arrested by the Germans and sent to the nearby concentration camp KL Stutthof. Nearly a hundred of them died within the next seven months upon their arrival, and were buried in a clandestine mass grave in a nearby forest. However, the exact nature of their death is unknown, as it is unclear what the attitude of the aggressors was toward the victims. We do not know whether there was only one executioner or there were several assassins, nor if the killing methodology was consistent with the other state-regulated executions.The studied material represents the commingled remains of a minimum thirty-four people, possibly all male, aged from under eighteen to over sixty at the time of death. Perimortem traumatic lesions are shown mainly on the skull bones. We asked whether the perimortem trauma lesions visible on the victims’ skeletons could be informative on the cause and manner of their death.Our results show the prevalence of the perimortem trauma inflicted by a blunt object are on the parietal bones above the Hat Brim Line (HBL), which is commonly associated with a violent attack. The gunshot trauma was usually localized on the occipital bone or posterior parietal, which could indicate a shot to the back of the head, and this was commonly encountered during executions. No signs of defensive injuries can be explained either by restraining of the hands or by a surprise attack. The abundance and variability of the trauma type can be evident of multiple assailants. Moreover, the multiple impact points detected on several crania prove unnecessary overkill and brutality, which reflects the personal attitudes of the executioners towards the victims.
