Dziekanka: Death Transports and Killing under Cover of a Hospital
1939–1945; gas transports 1939–1941 · Killing patients, camp violence and experiments
Dziekanka near Gniezno was not simply emptied in a single operation. German authorities turned the hospital into an element of a long-term system of killing. Polish patients were taken away to die and, later, patients from the Reich were also brought to the institution. Understanding this history requires separating successive stages and the nationalities of victims from the overall number of deaths. [1] [2]
Editorial account based on the sources listed below. Sources checked: 5 September 2026.
- Victims and toll
- 1,201 people murdered in transports between 1939 and 1941 according to Maria Tomczak's analysis; the Polish share of the complete occupation-period total has not been established here.
- Perpetrators
- The German authorities of the Tiegenhof institution, management including Wiktor Ratka and staff participating in selection; Sonderkommando Lange.
- Documented methods
- selection of patients and removal for gassing · killing with medicines · starvation and denial of proper care · falsification of information about deaths
The role of the management
An earlier study by Agata Gut describes Wiktor Ratka selecting patients, Otto Reich giving sedative injections and Sonderkommando Lange transports for gassing. Administration and medicine cooperated with the killing unit. A patient had no possibility of refusing transport or checking its destination. [2]
Not 1,201 victims in one month
Maria Tomczak, analysing records and earlier publications, lists 595 people deported in 1939, 448 in 1940 and 158 in 1941. This yields 1,201 transport victims. That sum should not be assigned solely to the turn of December 1939 and January 1940, as older summaries suggest. The researcher distinguishes these actions from the later incorporation of the institution into the central T4 programme. [1]
Further killing and concealment of death
After the transports, killing continued within the institution. An IPN study lists poisons administered as medicines, false notices of causes of death and sham graves. Such measures concealed perpetration from families; they were not ordinary failures of treatment. [2]
The newer analysis points to the diverse wartime population of the hospital: alongside Poles, patients brought from Germany were held there. Preserved death registers do not automatically determine the cause of every death. The overall numbers of the dead, transported and murdered must therefore not be treated interchangeably or presented as one precise number of Polish victims. Separating these categories is the most important correction to a simplified account of Dziekanka. [1]
Limits of the findings
The older paper and the 2020 analysis assign figures to dates differently. Maria Tomczak's explicit reconstruction of the records takes precedence on this point. No single number of Polish victims across all stages has been calculated. [1] [2]

How we assess sources
The evidence base consists primarily of Polish scholarly publications, investigative findings, archives, museums and documented witness accounts. Reliability is assessed through the document’s provenance, scholarly method and the ability to check the finding. Statements by perpetrators and family accounts of perpetrators require especially critical comparison with other material. Two pages from the same institution may repeat one finding; they are not automatically treated as independent confirmation.
