He met General Dwight D. Eisenhower in France. During the capture of Albert Speer in Glücksburg Castle (Speer was Adolf Hitler's Minister of Armaments and War Production) Harsch translated for a British officer leading the arrest and he reported of the capture of Karl Dönitz in a hospital of Mürwik (Muerwik), who was the head of the Flensburg Government. Harsch also reported from the Nazi concentration camps in 1945 when the Allied forces made their advance, and in the early years of the so-called Cold War, Harsch correctly predicted that the Iron Curtain would eventually fall along with the Soviet bloc. His own newspaper reported in his obituary that "He seemed to be everywhere, or at least everywhere something important was happening."
