"The German invasion of Poland on 1 September 1939 began World War II in Europe, pitting the newly modernized army of Europe's great industrial power against the much smaller Polish army and introducing the world to a new style of warfare-blitzkrieg. Panzer divisions spearheaded the German assault with Stuka dive-bombers prowling ahead spreading terror and mayhem. This book demonstrates how the Polish army was not as backward as it is often portrayed and fielded a tank force larger than that of the contemporary US Army. Its stubborn defense gave the Germans some surprises and German casualties were relatively heavy for such a short campaign."--BOOK JACKET.
