1939年8月31日,格莱维茨事件爆发。当日,一支身穿波兰军装的德国党卫军冒充波军,袭击了德国边境的格莱维茨电台,并发表对德国的侮辱性讲话。随后,全德各电台都广播了“德国遭到了波兰突然袭击”的消息,希特勒以此为借口,签署入侵波兰的第一号作战命令,并于次日发动了对波兰的入侵。Re-enacted true story of successful assault by Nazis, posing as Poles, on a German border radio station so that Hitler could "justify" thereby his invasion of Poland.
