After some time back in the US, he joined the Berlin bureau of the "New York Times" in 1933, where he chronicled the rise of Nazi Germany. Within two days of the secret signing of the Molotov–Ribbentrop Pact he had managed to get news of it for a page-one story called "Nazi Talks Secret" whose subtitle included "Soviet and Reich Agree on East." On 26 August 1939, he filed a story that noted Nazi troops on the move near Gleiwitz (now Gliwice), which led to the Gleiwitz incident, a false flag operation, on 31 August 1939. (On 28 August 1939, the "Times" was still reporting on fears of a Gleiwitz raid.) In 1940, he was expelled from Germany.
