Mildred Gillars was indicted on September 10, 1948 and charged with ten counts of treason, but only eight were used at her trial which began on January 25, 1949. The prosecution relied on the large number of her programs recorded by the Federal
Communications Commission, stationed in Silver Hill, Maryland, to show her active
participation in propaganda activities directed at the
United States. It was also shown that Gillars had taken an oath of allegiance to Adolf Hitler.
