In five-and-a-half years, Landsberg Prison was the place of execution of 252 condemned war criminals, all of them by hanging.[4] Executions were carried out expeditiously. In May 1946, 28 former SS guards from Dachau were hanged within a four-day period.[5] Bodies that were not claimed were buried in unmarked graves in the cemetery next to the Spöttingen chapel.
