I knew that Germany invaded Poland on September 1, 1939, but this was a part of the story I had not heard:
In late August 1939, [Clare] Hollingworth was a 27-years-old cub reporter for the Telegraph in Poland. After talking a British diplomat into allowing her to borrow his car, she drove across the border into Germany, where she observed large numbers of troops, tanks and field artillery lined up along a road.
As she wrote in her autobiography, when the wind blew open burlap screens “constructed to hide the military vehicles . . . I saw the battle deployment.” Her story appeared in the London newspaper on Aug. 29 under the headline “1,000 Tanks Massed on Polish Frontier.” Germany invaded Poland three days later.
