On 17 September 1939, one of the many camps in Pomerania (Internierungslager Karlshof) was established in Karolewo. It was intended for the extermination of the Polish and Jewish populations from the counties of Sępólno, Tuchola, Bydgoszcz, {{Interlanguage link|Wyrzysk County|lt=Wyrzysk|pl|Powiat wyrzyski}}, and Chojnice. The camp was dissolved in mid-December 1939.
