the Riegner Telegram notified the Allies, but they largely ignored the information which stated the estimated number of 3.5 to 4 million Jews, and the planned use of hydrogen cyanide. In 1943, the Gestapo noticed his activities, and Schulte had to permanently flee to Switzerland with his wife, while his two sons had to remain under German control to fight in the Wehrmacht. One son was killed in the war. After the war, Schulte remained silent. Riegner always refused to acknowledge who had supplied him with the information as this was "the one request he ever made of me".
