On 20 June 1942, four Polish prisoners dressed in stolen SS uniforms, armed themselves with stolen weapons, and drove out of Auschwitz concentration camp in the commandant’s personal staff car. It was one of the most audacious escapes of the Second World War, and all four men survived. Two years later, on 20 June 1944, a German V-2 rocket reached 176 kilometres altitude during a test launch, crossing the Kármán line and becoming the first human-made object to enter outer space. The following year, on 20 June 1945, the US Secretary of State approved the transfer of Wernher von Braun and his team of Nazi rocket scientists to America under what became Operation Paperclip. And in the early hours of 20 June 1631, Barbary corsairs raided the Irish village of Baltimore, taking over a hundred men, women, and children captive to be sold into slavery in North Africa. Clare Vale explores these intersecting stories of escape, innovation, moral complexity, and human resilience.
