How do you save people from concentration camps when there’s a war raging across Europe and beyond? It’s a big question, but the answer sounds scarily simple: in the case of Scandinavia, you get permission from Himmler himself, then commandeer some buses, ambulances and trucks, collectively called the White Buses. You use a volunteer network to drive them from Theresienstadt, Dachau and Ravensbrück through war-torn Europe to the safety of Malmö’s medieval castle.
Last year I went to Malmö and saw the extraordinary place where those liberated spent their first weeks of freedom. Unsurprisingly, it gave me the research bug.
