I was convinced before the war started that it was a great disaster, a great wrong. Even after the campaign in Poland my conviction didn't change because on 3rd September, the third day of our going to war, the Western Powers had declared war on Germany. After the campaign in France in 1940 my conviction became uncertain, but when I heard one or two months after the armistice with France that now Hitler was to go with Russia, the old conviction came up again and it was at this moment that I changed the place of living for my family, moved them from Berlin to the place where they are today.
