The legend of Polish cavalry attacking German tanks with sabres and pikes is perhaps the most famous myth of the September 1939 campaign. I believe that it is impossible to determine exactly where and when this myth originated, but it is still alive both in Poland and beyond its borders. The myth was created during the entire Polish campaign and the years that followed. The fact that such an attack would have been a clear suicide, and no commander in his right mind would have given such a stupid order, in no way diminishes the popularity of these stories, repeated with wonder even by well-known authors. It proves that it is very difficult to remove any stereotype, however utterly absurd, when it is so deeply ingrained.
