This book is about how and why the Polish elite betrayed their people in the bloody September of 1939, about the true causes of World War II and the role that Poland played in it. This book is about the valor of ordinary Polish soldiers, and it is also about the betrayal of Polish politicians and generals who doomed their own people to slaughter. But in general, this book is about Poland of our days, in which, invisible to the outside eye, the centuries-old battle still continues between Slavic Poland and European Poland - and this battle is still very far from over.
