According to Louis P. Lochner, while stationed in Berlin he received a copy of a speech by Hitler from his "informant", which he published (in English translation) in his book What About Germany? (New York: Dodd, Mead & Co., 1942) as being indicative of Hitler's desire to conquer the world. In 1945, Lochner handed over a transcript of the German document he had received to the prosecution at the Nuremberg trials, where it was labeled L-3.
