Between 1942 and 1945, Jewish inmates of a forced labour camp and later Auschwitz subcamp at Blechhammer (Blachownia Slaska, Upper Silesia) worked alongside British prisoners of war on the construction site of a giant synthetic fuel facility, the Oberschlesische Hydrierwerke. This paper examines the multifaceted forms of interaction between these two groups, who were situated at the opposite ends of a spectrum ranging from high survival rates to certain death. By reframing the Jewish inmates' perceptions of the POWs, it seeks to shed new light on a controversial debate on the nature of the relationship between them and the British prisoners. The paper argues that important aspects have been missing from this debate, as the Jewish inmates were not sufficiently represented and not viewed as active protagonists. The relations between Jews and British POWs were not one-sided, but rather interdependent in complex ways. Both groups used these contacts to gain strategic information on the war and jointly contributed to the Allied resistance effort. The barter with British POWs played a crucial role in the collective and individual survival strategies of Jewish inmates, whereas the British increasingly depended on the Jewish inmates to procure basic foods, when German rations ceased to be allocated. An analysis of the effects of British aid-giving showed that the actual impact on the physical survival of the emaciated inmates was negligible. However, these gifts were commonly interpreted as humanitarian gestures by both sides. Altogether, the British were encouraging symbols of resistance against the Nazi regime in the eyes of the inmates. Negative experiences were rarely corroborated and were often linked to poor English language skills, or a stronger identification with other nationalities.
