By spring 1940, Koischwitz was working as a program director in the U.S.A. Zone at the
Reichs-Rundfunk-Gesellschaft, German State Radio. He broadcast talks to the U.S. under the pseudonyms of ‘Mister O.K.’ and ‘Doctor Anders’. His propaganda was directed to college students and German-American listeners who might be susceptible to
Nazism. He spoke on literature, music, drama, philosophy and geopolitics, his broadcasts being
anti-Semitic,
anti-British, anti-
Roosevelt,
Sinophobic, and
anti-communist in tone. In Berlin, Koischwitz began a relationship with another American working for German state radio,
Mildred Gillars, who would become widely known as ‘Axis Sally’. Koischwitz and Gillars became lovers and before long Koischwitz was working her into his political broadcasts. Together they formed a powerful propaganda duo. They began a joint series, the
Home Sweet Home Hour, aimed at the Allied forces in North Africa. Koischwitz also edited a magazine for American POWs,
The Overseas Kid, and in September 1943 he was made head of the USA Zone. From October 1943 he and Gillars toured POW camps in Germany, interviewing captured Americans and recording their messages for their families in the US. The interviews were then edited for broadcast as though the speakers were well-treated or sympathetic to the Nazi cause. After D-Day, June 6, 1944, US soldiers wounded and captured in France were also reported on. Koischwitz and Gillars worked for a time from
Chartres and Paris for this purpose, visiting hospitals and interviewing POWs. Koischwitz also wrote and produced propaganda sketches and plays with Gillars in the lead, the most notorious of which was the
Vision Of Invasion broadcast on May 11, 1944, a few weeks before the
D-Day invasion of
Normandy, France. Koischwitz broadcast for almost the entire war, towards its end appealing for the United States to join Germany in fighting the approaching
Red Army. ==Charges of treason==
