Sixty-five-years ago, a fleet of 62 U.S. Air Force bombers dropped their deadly cargo on Prague. As soon as the all-clear sounded a Red Cross photographer named Stanislav Maršál went out into the streets to document the aftermath; he was so traumatised by what he saw that he hid the photos away for sixty years. Now, five years after his death, the photographs are being shown for the first time, at an exhibition in Prague’s New Town Hall.
